Noise can carry quite noticeably throughout a home. That’s why many homeowners opt for soundproofing solutions that reduce noise within their homes and make for a more comfortable, peaceful living environment. Soundproofing is beneficial for any homeowner, especially those with young kids or pets who may be subject to more noise. Not only is soundproofing nice for homeowners themselves, but it’s also something neighbors will appreciate. The overall goal of soundproofing is to minimize the noise entering and exiting a certain room or even the whole house.

Soundproofing is a smart home investment. The average soundproofing cost range is between $1,000 and $2,500. The average homeowner spends around $1,500 to add soundproof windows and doors, plus another layer of insulation in a 130 sq.ft. room. The cost of soundproofing a room can be as low as $300 to add an acoustic door or wall panels in a room of the same size. Costs run as high as $45,000 for comprehensive soundproofing, including double insulated walls, new soundproof windows, and solid core doors throughout a 1,500 sq.ft. home.

How Does Soundproofing Work?

Soundproofing a space requires different materials to block two types of noise: airborne noise and impact noise. As the name suggests, airborne noise travels from room to room through the air. Whistling, shouting, screaming, and other high pitch sounds are common examples of airborne noise. Impact or flanking noise occurs when soundwaves travel through building materials like bricks, plaster 1, and timber. Sounds that pass through the floors, ceilings, and walls are impact noises and generally low pitched. The sound of feet, falling objects, and washing machines are usually impact sounds. Soundproofing materials vary for each type of noise. Foam and similar fibrous materials are preferred for blocking airborne noise, while impact noise is best blocked by rubber sheets. By using materials that absorb or reduce sound, you can achieve significant noise reduction.

Soundproofing is used in residential and commercial buildings throughout the country with a special rating system. In the United States, the sound insulation of buildings is measured in terms of sound transmission class (STC). While a poorly-made partition wall, through which you can hear everything happening on the other side, will have an STC score in the 20s, a luxury hotel room may have a score in the 60s. Most residential buildings have a score between 30 and 45.

300 sq.ft.$3,600 - $7,500$3,000 - $9,000

Soundproofing New Construction

Soundproofing a house during construction costs $12 to $25 per sq.ft. Contractors incorporate the soundproofing solutions into the initial build and labor costs. Noise-reducing insulation can be installed with the building frame and plaster instead of removing these materials to install insulation in an existing room. Double-layered glass on windows and doors helps with soundproofing and can be installed during the construction process instead of being replaced in a room that’s already built. If homeowners think they want comprehensive soundproofing throughout their new home, it often pays off to incorporate this project when building rather than later on when the house is finished.

Soundproofing in an Already Built Room

The average cost of soundproofing an existing room is $10 to $30 per sq.ft. You can seal doors and windows or get newer insulated glass. Adding insulation works well but involves more labor to get inside the walls and redo the plaster. A few inexpensive options are available for soundproofing an existing room, such as a door sweep that reduces external noises and blocks insects. Door sweeps cost $25 to $100. Acoustic wedge panels cost $1.60 to $4.60 per sq.ft. to install. Another option is to blow insulation into the existing wall by drilling a hole or add mass loaded vinyl ($100 to $200 for a 40 sq.ft. roll) between two drywall layers. Sometimes homeowners decide to build a soundproof wall over the existing wall for long-lasting sound reduction, especially in living rooms or studios.

Soundproof Room Cost by Area

You can look at soundproofing prices based on which area of the room where you are working. The areas outlined in the table are the most common parts of a room that can be soundproofed, with the average costs for new builds or existing rooms.

Window Soundproofing Cost

Homeowners have the option to soundproof just one area of a room or make changes throughout the entire space. Some may choose to soundproof just the windows or doors and see if that makes a difference or if they need to invest in more soundproofing solutions. Here are the average costs of popular home soundproofing projects. Those that are DIY projects can be done by a homeowner or a professional. However, because of the simplicity of the project, it won’t add much to the labor costs, especially when combined with other soundproofing tasks.

Acoustic Caulk for Windows

Acoustic caulk 2 costs $15 to $100 and serves as an affordable way to seal gaps between window frames and interior walls. Outdoor noise filters into the home through these gaps and affects the sound transmission. Acoustic caulk is noise-proof and latex-based, allowing it to block sound while maintaining full window function. It provides greater flexibility than standard silicone caulk and won’t crack or shrink when you open or close the windows.

Window Seal Price

The average price for a window seal kit is $20 to $80. These budget-friendly soundproofing kits contain a durable window film and double-sided tape. The heat shrink film is clear, so it doesn’t impact the view. When secured over the window glass, it adds an extra layer of insulation and noise protection. If you want to make outside noise less noticeable without a complete window replacement, this is a good place to start.

Soundproof Window Plug

A soundproof window plug should cost around $25 to $75. This soundproof sponge is around 1’ to 3” thick and can be inserted into the window frame. Ideally, it will be an airtight fit, which offers the best protection from outdoor noise like cars, barking dogs, and loud neighbors. Look for window plugs made from closed-cell foam that’s water and chemical resistant. Window plugs work well for home offices and theaters where you want it to be extra quiet.

Filling Holes in Window Frames

The cost to fill holes in window frames is $50 to $300. The final price for this small soundproofing project depends on how many windows you do and how much filling material is needed. Putty, UPVC glue, or epoxy wood filler work to plug holes where sound may be entering. Sometimes homeowners combine this method with window plugs or window seals to improve the soundproofing level.

Sound Dampening Curtains

The average cost of sound dampening curtains is $100 to $400. Generally, the heavier the curtains, the better they work at stopping noise. Velvet, vinyl, and similarly thick curtains absorb sound and prevent echoing for quieter living spaces. While loud noises may not be completely blocked, they are absorbed pretty well. Blackout curtains help with noise reduction while also blocking light from bedrooms and living rooms.

Noise Reduction Window Inserts

Noise reduction window inserts cost $250 to $500 to install. Window inserts are essentially an extra layer of protection against noise vibrations inside the windows. These inserts press into the current window frames to seal drafts and block outside noise. One of the benefits of inserts is that they don’t damage the window frame. This means they can be used for historic original windows if you don’t want to change them, but you want to improve noise reduction.

Soundproof Window Cost

The average cost of installing soundproof windows in a new installation is $500 to $1,000. The cost of replacing regular windows with sound dampening windows is $550 to $1,200. In addition to soundproof windows with acoustic glass, there’s also the slightly more affordable option of standard laminated glass windows that cost $125 to $2,750. Soundproof windows have thicker laminated glass to essentially create a glass and plastic sandwich to lock sound in and prevent it from filtering into your living spaces. Pockets of dead air within these windows minimize noise transmission and protect against loud, disruptive sounds inside the house.

Door Soundproofing Price

Soundproofing doors cost around $300 to $3,500 for new construction and $500 to $4,000 to replace existing doors with soundproof options. You can make smaller upgrades to your door to lower the sound transmission. Often, homeowners start with smaller, less expensive changes and see if they provide a suitable level of soundproofing in their home before replacing the doors. However, it depends on personal preference and each individual home. Soundproofing projects labeled DIY may be completed by a homeowner or a professional. They are relatively simple and won’t contribute much to the labor costs.

Acoustic Door Thresholds

The average cost of acoustic door thresholds is $30 to $100. Acoustic thresholds are similar to door sweeps because they are designed to prevent noise from filtering in through the bottom of the door. Thresholds are installed on the floor instead of the door, so you can use the door without dragging the door sweep across the surface. Hardwood floors and other hard surfaces often benefit from acoustic door thresholds.

Soundproof Door Seal

Sealing a door to make it soundproof costs $35 to $90. Weather stripping around the door covers the sides, top, and bottom. This is most common for front doors and patio doors that serve as key entry and exit points for the home. However, you can seal any door in the house to block sound from carrying as much. Sealing doors helps them last longer and prevents pest problems and moisture damage.

Door Sweep for Noise Reduction

The average cost of a door sweep is $60 to $120. Noise often filters in through the bottom of the door, where there is a gap between the door itself and the floor. A door sweep is attached to the bottom of the door to seal the threshold gap. Not only is a door sweep a good option for reducing noise like pets barking and people talking, but it keeps dust, insects, and moisture out.

Mass Loaded Vinyl on Door

The average cost of mass loaded vinyl 3 for soundproofing a door is $100 to $200. This densely packed vinyl absorbs sound waves and reduces vibrations. Adding mass is best for cutting down on low frequency sounds. Mass loaded vinyl rolls are versatile and can be cut to fit the door, plus used on other surfaces throughout the home. Different thickness levels are available, as well as fire-resistant and odorless varieties.

Acoustic Panels on Door

The cost of acoustic panels for doors averages $100 to $300. These sound blocking panels are easy to install and remove. They hang over the door frame to reduce noise transmission between different parts of the house. Acoustic panels block sound and reduce echo. For homeowners with hollow core doors, acoustic panels are a good place to start soundproofing before replacing the doors altogether.

Replacing Hollow Core Doors with Solid

The average cost of replacing hollow core doors with solid doors is $150 to $2,000. This is an important project considering sound transmission commonly occurs in weak spots in the doors or walls. A door with a hollow core comprises around 20 percent of sound transmission in a noisy room. These hollow core doors are most common in new home construction. By switching out these weak points for doors with solid cores, you can block out considerably more sound for a quieter, more relaxing room. Solid core doors have a thin wood, vinyl, or MDF veneer covering the wood pulp core. Steel and aluminum solid cores are also available, but they are lighter than solid wood.

Soundproof Blanket for Door

For $300 to $500, you can get a soundproof blanket for your door. Made from heavy, sound absorbing materials, these blankets cover the door and muffle sound. Various options are available. While they may not be the most attractive soundproofing solution, they work well, especially for children’s rooms and offices where it’s important to cut down on as much noise as possible.

Soundproof Door Price

Soundproof doors range in price from $300 to $4,000. The cost of new construction soundproof doors with a dense sound absorbing inner layer is around $300 to $1,100 per door. Sliding glass doors like those on patios are usually more expensive to install, around $1,800 to $4,600. The benefits of sliding glass doors include great aesthetic appeal and a boost in home value. They are made of laminated glass that cuts sound transmission by over 75 percent. Soundproof glass doors are well-insulated and difficult to break.

Soundproof Walls Cost

If a certain room in your home is very noisy, soundproofing the walls makes a big difference. Many different ways are available to soundproof your walls, ranging in price from $100 to $350. Some of the same soundproofing solutions recommended for doors can be used on the walls too, or you can renovate the walls themselves to reduce sound transmission.

Rockwool Sound Insulation Price

At $1 to $2 per sq.ft., rockwool sound insulation is one of the most affordable ways to soundproof your walls. The stone wool insulation is used to absorb sound and reduce noise within stud walls and floors. The mildew and fire-resistant insulation has a sound dampening R-15 option and a special soundproofing variety specifically designed to create an interior wall noise barrier.

Mineral Wool Batts

The average cost of mineral wool batts is around $1.50 to $2.50 per sq.ft. This loose-fill insulation is fiber-based and slightly denser and stiffer than fiberglass 4 insulation. It’s used to reduce sound in steel stud interior walls and floors. In addition to absorbing sound, mineral wool batts insulation protects against fire and offers impressive thermal performance.

Soundproof Foam for Walls

Soundproof foam costs $1.50 to $5 per sq. ft. and is used to absorb echo inside the house. It’s most commonly used to soundproof a home theater or studio and comes in many colors and patterns. The foam is mounted directly to the wall and may be used in addition to heavy curtains, wall art, and other soundproofing modifications to make noise less noticeable within a room.

Soundproof Paint Cost

Soundproof paint costs around $2 to $4 per sq.ft. or $30 to $40 per gallon of paint without labor. Much like regular paint, soundproof paint can be used on all surfaces, including walls. It can block mid-level frequencies and consists of a resilient base coat and a mass building finish coat. You can find non-toxic, environmentally-friendly soundproof paint varieties that minimize tinning, ringing, and echoing.

Mass Loaded Vinyl Cost

Most homeowners pay around $2.50 to $5 per sq.ft. of mass loaded vinyl. This flexible material contains high-density metal, sand, and salt particles that reduce sound by adding mass to the walls, ceilings, and floors. It’s designed especially for noise control and can be sandwiched between layers of drywall to cut down on sound transmission within walls significantly. Most mass loaded vinyl comes in 4-foot rolls to cut and hang on walls.

Cost of Acoustic Panels

The average cost of acoustic panels is $8 to $12 per sq.ft. Acoustic panels are good for noise reduction and sound control, as they cover the existing wall and absorb sound effectively. Wall-mounted and freestanding panels can be pushed up against the wall. Also, you can hang panels from the ceiling to mitigate problematic noise.

Acoustical Caulk

Acoustical caulk costs $15 to $30 per 28 oz. Caulk serves as an extra defense against unwanted noise, particularly when there are two layers of drywall. Caulk can be put in between the drywall layers to deaden vibrations that would otherwise travel throughout the wall. Acoustical caulk can be used to seal any cracks or holes in the walls, floors, or window frames. This is something you can do yourself, otherwise most professionals will add acoustical caulk as part of other soundproofing projects.

Decoupling Cost

The average cost of decoupling is $15 to $60 for an hour of professional labor to complete this soundproofing job. Decoupling is a simple and effective soundproofing technique that involves mechanically separating the two sides of a wall so that sound cannot pass through it easily. The two sides of a traditional wall are coupled by wood studs, making it easy for sound to pass from one side to the other. When you use a resilient decoupling mount, it hinders sound transmission and improves the soundproofing performance.

Cost to Repair Drywall Cracks

Drywall crack repair is another soundproofing option that costs $75 to $350. Noise can seep through cracks in the drywall 5, especially in older homes where the existing walls may be decades old and in need of repairs. By filling and smoothing these cracks, you improve the sound protection in a room. Sometimes homeowners repair drywall cracks first and then make more wall improvements to enhance the soundproofing.

Resilient Channel over Existing Drywall

The average cost of installing a resilient channel over existing drywall is from $150 to $200. This specially-designed metal bar improves the soundproofing of drywall, sheetrock, and ceilings. Resilient channels must be installed properly over existing drywall to achieve the best possible sound reduction. It’s best to use resilient channels to hang drywall.

Tie New Block Wall into Existing Wall

The cost to tie a new block wall into an existing wall is $150 to $350. The more walls you’re working on, and the more complex the project, the more professionals charge. This option is most popular with brick or concrete walls. The idea is to build a second wall in front of the current wall, leaving a small 100 mm gap between the two. This gap is filled with foam, rubber, and fibrous material to absorb noises coming through the wall and significantly improve the room’s soundproofing.

Sound Absorbing Wall Art

Most sound absorbing wall art is priced at $150 to $300 each. This is a unique option for homeowners who want to improve the soundproofing in their home while also respecting their interior design. Wall art panels come in several patterns and colors and offer an additional barrier to trap sound from the wall. Generally, the larger and thicker the art piece, the better it absorbs sound inside the home. You can hang the wall art on your own or ask a professional for help while they do the rest of the soundproofing, but it shouldn’t add much to the labor costs.

Double Drywall for Soundproofing

Expect to pay around $40 to $60 per sheet of drywall. Double drywall involves adding a second layer of drywall to produce better insulation and protection against sound. By putting soundproofing material between the two layers, you drown out much of the noise that would otherwise carry through the walls. Double drywall is a good solution for walls with hollow cavities that transmit noise easily.

Soundproofing Ceiling Cost by Type of Project

Soundproofing the ceiling is another possibility, especially in a home with multiple levels or a loud tin roof. Ceiling soundproofing solutions are especially popular in homes with basements or hardwood floors on the main level that carry sounds more than carpet. To block sound waves traveling through the ceiling, you can add insulation between ceiling joists, including on top of any recessed ceiling lights, add resilient sound clips on ceiling joists, add a second layer of drywall using green glue, or fill the space between seams and the perimeter using acoustic caulk. Acoustic panels and mass loaded vinyl can also add density to the ceiling to prevent sound transfer. The average costs for different ceiling soundproofing projects are highlighted below.

Mass Loaded Vinyl$2.50 - $5 per sq.ft.
Resilient Sound Isolation Clips$5 - $10 per clip
Green Glue$15 - $30 per 28 oz.
Double Layer Drywall$40 - $60 per sheet

Hanging Acoustic Panels from Ceiling

Acoustic ceiling panels cost $1 to $10 per sq.ft. Like acoustic wall panels, ceiling tiles are cheaper, around $1 to $4 per sq.ft. if it’s the mineral fiberboard that’s standard throughout the homebuilding industry. High-end wood and metal panels cost more, around $3 to $10 per sq.ft. When installed on the ceiling, acoustic panels absorb noise from the roof or upper levels of the home, such as footsteps, rain, and music.

Soundproof Ceiling Insulation

The average cost of soundproof ceiling insulation is $1.50 to $4 per sq.ft. Fiberglass insulation adds a layer of protection between the ceiling and the building structure above, whether it’s a second layer of living space, the attic, or the roof. Many homeowners choose soundproof ceiling insulation for their basements and first levels. This way, they lower the noise from activity on the upper floors. The combination of insulation and drywall works the best.

Acoustic Foam Panels for Ceiling

Acoustic foam panels are $1.50 to $5 per sq.ft. to install on the ceiling. The foam absorbs noise and is preferred for home studios, theaters, and entertaining rooms. The sound of music and movies is kept inside the space without being so loud in other areas of the house. These panels improve sound quality and reduce echo.

Mass Loaded Vinyl for Ceiling

Homeowners pay $2.50 to $5 per sq.ft. for mass loaded vinyl on the ceiling. The material is the same as what’s often used on walls, with densely packed vinyl to absorb sound and produce quieter living spaces. Flexible rolls of vinyl are easy to work with and can be cut to fit the ceiling, plus used for soundproofing other building materials and areas of the home.

Resilient Sound Isolation Clips Cost

Resilient sound isolation clips cost $5 to $10 per clip. They are often used to mount drywall and trap sound, so it doesn’t carry throughout the whole space. Resilient sound isolation clips can be added to ceiling joists to improve the STC rating. They are an important part of decoupling ceilings to minimize noise transmission.

Green Glue Ceiling Soundproofing

Green Glue costs $15 to $30 per 28 oz. This noise proofing compound forms a damping system when put between two rigid drywall layers. With a unique polymeric formula, green glue turns sound waves’ mechanical energy into heat, reducing audible sound throughout living rooms. Green Glue is the best for dissipating low frequency noise.

Double Layer Drywall Ceiling

You will pay $40 to $60 per sheet of drywall to create a double layer drywall ceiling. Two layers of drywall are better than one, especially when a soundproofing compound is inserted between the layers to lock in noise and prevent it from causing noise problems. Contractors often recommend adding an additional layer of drywall, particularly in lower-level rooms that can hear the noise from above.

Soundproofing Ceiling Cost by Location

Sometimes homeowners prefer to soundproof the majority of their living space rather than just one room. These projects usually involve soundproofing the ceiling. The cost of ceiling soundproofing in different areas of the house depends on the square footage, with prices ranging from $1 to $6 per sq.ft. Here are the average costs of installing soundproof ceilings in these common locations.

Cost to Soundproof a Garage, Basement, Condo, or Apartment Ceiling

Cost to Soundproof a Garage, Basement, Condo, or Apartment Ceiling

LocationAverage Costs (Labor Included)
Garage$200 - $1,000
Basement$500 - $3,000
Condo$800 - $4,000
Apartment$850 - $4,000

Soundproofing Garage Ceiling

The average cost of soundproofing the ceiling in a garage is $200 to $1,000. Many homeowners don’t go overboard on the aesthetic appeal of the garage ceiling. However, soundproofing can be a worthwhile investment, especially if the garage is situated underneath part of the house. Some garages don’t have insulation, so adding insulation and drywall to the ceiling is the main cost.

Cost to Soundproof Basement Ceiling

Soundproofing a basement ceiling costs $500 to $3,000. Basement soundproofing is popular because, in many homes, residents can hear footsteps, music, and other noises coming from the upper floors. This project typically costs more than the garage ceiling because homeowners prefer a finished basement ceiling that’s soundproof and attractive. A double drywall layer, ceiling insulation, or acoustic panels improves basement sound transmission.

Soundproofing Condo Ceiling Cost

The average cost of soundproofing a condo ceiling is $800 to $4,000. Many condo building residents report they can hear noise coming from the surrounding units, including those on the floor above. In that case, soundproofing the ceiling makes a difference while also locking in noise from music, TV, pets, and children. To maintain the interior design of the condo, it’s preferable to have a double drywall layer with insulation and acoustic panels for a nice finish.

Soundproofing Apartment Ceiling

The average cost of soundproofing an apartment ceiling is $850 to $4,000. Apartments are similar to condos in terms of soundproofing requirements and suggestions. But the final cost depends on the apartment square footage and the level of soundproofing needed. Acoustic panels and Green Glue with double layer drywall produce the most efficient soundproofing in an apartment, helping to block out the noise from neighbors.

Cost of Soundproofing Floor

If you are looking to soundproof your room against impact noise (the sound of footsteps or objects falling against the floor), a heavy carpet and rug pad offer a quick and easy fix. If it is new construction, you can install resilient underlayment, vinyl barrier, and soundproof insulation between the floor joists and sound clips below the joists for best results. Carpet underlayment, which consists of a resilient acoustic foam layer with a vinyl barrier on one side, offers good results for carpeted floors. Here are the average costs for the most popular floor soundproofing projects, including those with professional installation and several DIY projects that don’t add to labor costs.

Soundproof Floor Underlayment

The average cost of a soundproof floor underlayment 6 is $0.20 to $0.50 per sq.ft. This underlayment is placed beneath carpet, hardwood, tile, or laminate floor. It serves as a protective layer against sound transmission and keeps cold floors warmer. A soundproof underlayment is easier to install on naked floorboards before the final flooring is installed. Otherwise, you need to remove the top layer of flooring to install the underlayment.

Soundproof Carpet Pad

The average cost of a soundproof carpet pad 7 is $0.20 to $1 per sq.ft. These pads support carpet floors and create a sound barrier to keep unwanted room noise to a minimum. Sound absorbing carpet pads are made of thick rubber that’s durable and dynamic for any room in the house. Keep in mind the amount of traffic in the room, so you know how thick the carpet pad needs to be. If it’s a living room, kitchen, or hallway where people are walking regularly, the carpet pad should be thicker than if it’s a bedroom or office where there won’t be much activity.

Interlocking Floor Mats

Interlocking floor mats cost $1 to $2.50 per sq.ft. These mats are commonly used in home gyms and playrooms where there is heavy equipment and physical activity. Interlocking floor mats provide a cushion against sound and can be placed on top of existing hard floors. Rubber foam mats are easy to put together and move around, so they are preferred for temporary and versatile soundproofing. They can be kept in place for solid soundproofing. That’s a matter of personal preference.

Sound Absorbing Carpet Cost

The average cost of sound absorbing carpet is $1 to $3 per sq.ft. Soft fabrics in plush carpets are naturally sound absorbing, and the thicker the carpet, the better. Carpet absorbs sound waves and keeps rooms warm and welcoming. Special acoustic carpets are optimized to absorb the sound of voices, music, and footsteps.

Sound Dampening Rug

A less permanent option is a sound dampening rug, which costs $1 to $4 per sq.ft. Instead of installing a full carpet, you can lay down a rug that achieves a similar effect. A sound dampening rug can be moved out of a room and cleaned when needed, but otherwise, it works well to dampen the volume of noise and make it less noticeable throughout the home. When combined with furniture and cushions, a sound dampening rug makes a noticeable difference to a room.

Blown Sound Insulation Between Floors

Installing blown sound insulation between floors costs $40 to $200. This insulation is made of fiberglass or cellulose to create a tight fit that seals around all the flooring framework, including pipes and openings. Blown sound insulation makes a strong sound barrier thanks to the dense filling, which needs professional labor to insert into the floor using a drilled hole.

Green Glue Floor Soundproofing

Green Glue for soundproofing floors costs $15 to $30 per 28 oz. This unique sound reduction compound is used for floors, ceilings, and other home surfaces. It is best used between two floor layers, as it eliminates low frequencies and minimizes audible sound. This method is best done in new construction or a full renovation.

Soundproof Room Cost by Location

The overall costs of soundproofing a certain room vary greatly based on the room’s size, layout, and design. The project pricing depends on the extent of the soundproofing. For example, making minimal changes to cut down on sound in a living room will be much less expensive than decking out a home theater with state-of-the-art soundproofing solutions. Here are the average costs for soundproofing different rooms in the house.

Cost to Soundproof Room by Location: Furnace Room, Bathroom, Laundry Room, Home Office, Bedroom, Basement, Home Theater...

Cost to Soundproof Room by Location: Furnace Room, Bathroom, Laundry Room, Home Office, Bedroom, Basement, Home Theater...

LocationAverage Costs (Installed)
Furnace Room$100 - $250
Bathroom$100 - $300
Laundry Room$200 - $800
Home Gym$300 - $900
Home Office$300 - $1,000
Bedroom$300 - $1,500
Kitchen$400 - $1,500
Basement$500 - $3,000
Home Theater$1,000 - $5,000

Soundproof Furnace Room

The cost of soundproofing a furnace room is $100 to $250. This average price is relatively low compared to other rooms in the house, as this is usually a mechanical space where the furnace, water heater, and pipes are located. While many homeowners want to minimize the sound coming from this machinery room, they usually aren’t as concerned with the aesthetic appeal of the furnace room. Simpler, less expensive soundproof methods like acoustic panels and door sweeps may do the trick.

Soundproof Bathroom

The cost of soundproofing a bathroom is between $100 and $300. This is another small space in the house, so replacing the current surfaces with soundproof ones can be more affordable than large living rooms and bedrooms. Bathroom rugs reduce noise on the hard floors, while insulated doors and windows have a positive impact on the overall noise reduction.

Soundproof Laundry Room

The average price of soundproofing a laundry room is $200 to $800. The main source of sound in the laundry room is the washing machine and dryer. Laundry rooms that are close to the garage or kitchen may also have noise from those rooms. Laying down rugs or interlocking floor mats is a good place to start, while insulated walls with double layer drywall produce a dramatic reduction in noise coming in and out of the laundry room.

Soundproof Home Gym

Soundproofing a home gym costs $300 to $900. While most home gyms are no larger than a bedroom or office, they usually contain some large workout equipment that produces its fair share of noise. Most people like to play music or TV while working out, so soundproofing the gym keeps the noise down in other areas of the house. Floor mats and acoustic panels on the wall are the most common soundproofing projects for home gyms, but all the walls, ceiling, and floor can also be insulated for the best results.

Soundproof Home Office

The majority of homeowners spend between $300 and $1,000 to soundproof a home office. Thick carpet and rugs are a smart investment to make home offices less noisy and more comfortable, while acoustic wall and door panels also reduce noise filtering through the rest of the house. The whole point of a home office is to have a private, quiet place to work, which is why many homeowners pay a little more to have double insulated walls and ceilings in their office space.

Soundproof Bedroom

The average cost to soundproof a bedroom is $300 to $1,500. Installing carpet pads and an underlayer traps noise, as can heavy curtains and acoustic panels. To increase the privacy and sound reduction in a bedroom, homeowners can use mass loaded vinyl and thick insulation throughout the floors, ceilings, and walls. Double glazed windows and solid core doors are also recommended for soundproofing a bedroom.

Soundproof Kitchen

Most kitchen soundproofing projects cost $400 to $1,500. A lot of noise naturally comes from the kitchen with cooking, cleaning, and gathering. To control the noise entering and exiting the kitchen, acoustic panels, double-glazed windows, and insulated drywall are smart soundproofing solutions. While hard flooring surfaces are preferred in a kitchen, a sound absorbing underlayer or stylish rug helps reduce sound.

Soundproof Basement

The average cost of soundproofing a basement is $500 to $3,000. Basements often need insulated ceiling or acoustic ceiling panels to minimize sound coming from the upper levels. Carpet flooring throughout the basement and double drywall keep the space warm and quiet. Soundproofing in basements may include insulated windows and solid doors to keep the basement noise from interfering with the rest of the house.

Home Theater Soundproofing Cost

Soundproofing a home theater costs $1,000 to $5,000 on average. This space requires special soundproofing methods because the acoustics are important to keep sound from escaping and entering the room and to ensure the best possible sound quality. Acoustic paneling and sound absorbing materials are typically added across all the walls, ceilings, and floors to muffle as much sound as possible.

Labor Cost to Soundproof a Room

While a few soundproofing projects can be done by yourself, such as laying down a rug or using a door sweep, most soundproofing work should be done by professionals. Dedicated soundproofing companies specialize in acoustic paneling and setups, but handymen can perform many soundproofing projects. Generally, handymen help with insulation, flooring installation, and window/door replacements. If you want premium professional experience and are focused more on achieving the best possible acoustics, it’s best to call a specialized soundproofing company.

Whether they charge per hour or offer fixed rates depends on each individual company. Most contractors and soundproofing professionals offer both pricing options depending on the project and labor required. The average labor cost for soundproofing one room is $200 to $400, with hourly rates of $50 to $100 for handymen and $75 to $200 for soundproofing professionals. The time it takes to complete soundproofing varies greatly depending on the project. For example, a simple door sweep or acoustic panel installation can be done in under an hour, while installing new soundproof windows, doors, and insulation can take several hours or a full day.

Cost to Soundproof House Exterior

While most homeowners think of soundproofing inside their home, there are also options to soundproof the exterior of your house. To increase privacy, security, and comfort throughout your entire property, you may want to consider soundproofing the exterior, with average prices ranging from $500 to $4,500.

Cost to Soundproof an Exterior Door, Garden Room, Garage, or Fence

Cost to Soundproof an Exterior Door, Garden Room, Garage, or Fence

Exterior AreaAverage Costs (Installed)
Exterior Door$500 - $1,500
Garden Room$500 - $2,000
Garage$2,000 - $3,500
Fence$2,000 - $4,500

Soundproof Exterior Door

The average cost of soundproofing an exterior door is $500 to $1,500. You can start by weather stripping your front door or patio door to provide a better seal against outdoor noise. If you have a hollow exterior door, you can swap it out for a solid core door to better block street noise. The larger the door, the more it will cost. If you have multiple entry and exit points, such as a front door and a side patio, you will need to budget more to soundproof all your exterior doors.

Soundproof Garden Room Cost

Expect to pay around $500 to $2,000 to soundproof a garden room. These outdoor spaces come in different sizes, impacting the project cost. If the existing glass windows and doors are made of thin glass, they can be sealed or even switched out for double or triple glazed glass. A solid core door and acoustic panels also work well for soundproofing a garden room.

Cost to Soundproof Garage

The average price of soundproofing a garage is $2,000 to $3,500. The majority of this project cost goes toward sound absorbing garage doors with quiet operation motors. Adding weather stripping to the garage door so it’s fully sealed assists with noise reduction. Acoustic panels and insulation within the garage block out neighborhood noise.

Soundproof Fence Panels Cost

Soundproofing a fence averages $2,000 to $4,500. Special noise reduction fence panels can be attached to wood or vinyl fences to control noise levels. This upgrade is becoming more popular with families who want a safe space for kids to play in the back or front yard without so much noise coming in or out.

Soundproofing Using Home Decor

The way you decorate your home impacts soundproofing. Without even knowing it, you may be reducing sound transmission in certain rooms. Think about what you already have in your house and how it helps with soundproofing. Couches, chairs, cushions, curtains, carpets, and rugs all offer some level of soundproofing. For example, upholstered furniture and plants absorb sound, while rugs, art, and couch cushions reduce noise. If you’re planning to redecorate or invest in more furniture, remember that the thicker and softer the fabrics, the more it will make a difference to soundproofing.

According to The Spruce, having wall art such as paintings or photographs can help, too, especially if it’s a noisy wall. When paired with acoustic drapes or panels, home decor significantly lowers sound transmission throughout different rooms in the house. Consider layering rugs over carpet to add an exciting design element that offers soundproofing at the same time. Upholstered soft furniture works better at soundproofing than hard tables and wooden chairs.

Soundproofing vs Acoustic Treatment

Soundproofing and acoustic treatment methods are similar, although the latter is usually more expensive because they are done by acoustic professionals rather than general contractors who handle soundproofing. While soundproofing controls and isolates sound from an undesirable source, acoustic treatments improve and direct sound to a particular area. Acoustic treatments are commonly done in home theaters, where the direction and flow of sound make a huge difference. If the way music, TV, or movies sound in a room is the top priority, professional acoustic treatment is the best choice. If the main concern is absorbing noise coming from the outside or other rooms in the house, standard soundproofing solutions will work.

Acoustic Insulation vs Thermal Insulation

When looking into soundproofing, many homeowners wonder whether acoustic insulation or thermal insulation is better. The main difference between the two is what they restrict. Thermal insulation reduces heat transfer, and acoustic insulation minimizes sound reverberation and transfer. Acoustic insulation is preferred for a higher level of soundproofing, while thermal insulation helps, although not as much. Thermal insulation is targeted toward preventing heat loss and improving the energy efficiency and temperature control in a home. Due to the demand for both these products, there is now thermal acoustic insulation that reduces both heat and noise transfer. Thermal insulation costs $0.50 to $2 per sq.ft. while acoustic insulation is normally $0.75 to $3 per sq.ft.

Enhancement and Improvement Costs

Weather Stripping

You can soundproof your home for much less by installing a door sweep and using weather stripping foam tape around all sides of the door frame. It creates a better seal, reduces sound leaks, and keeps critters away. The average cost of weather stripping a home in the U.S. is between $200 and $600.

Chimney Soundproofing

An open chimney can be a source of unwelcome noise from weather, animals, and neighbors. You can soundproof a chimney in three ways: by using a chimney balloon ($45 to $55), by adding a flueblocker ($35 to $55), or by installing a chimney cap ($300 to $600). The first two methods are easy, and you may be able to do it yourself. If you do not have experience working on rooftops, it is recommended that you hire a professional to fit a chimney cone.

Additional Considerations and Costs

  • Rental. If you are renting your home, make sure you check with the landlord before beginning any soundproofing projects. It’s important to avoid issues and fines by getting approval for drilling and door replacements. Non-permanent solutions like hanging a soundproof blanket or laying down a rug should be fine, but anything that changes the home structure itself requires approval just to be on the safe side.
  • Best siding for soundproofing. The thicker the siding, the better it absorbs sound and stops outside noise from entering your home. Stone and brick are stronger soundproofing materials than wood and vinyl.
  • Air quality. Be on the lookout for air quality problems when soundproofing a room. When you make a room airtight, it reduces noise, but it makes the room stuffier unless you have a forced air heating/cooling system. Improper ventilation can cause health problems for people with asthma and other respiratory issues.
  • Egg cartons. Egg cartons don’t do much in terms of soundproofing. Because these boxes are made of very thin cardboard, sound waves go straight through them with little, if any, noise reduction. The only benefit is that egg cartons may slightly reduce echo and sound deflection.
  • Home resale value. Something small like door sweeps or hanging blankets won’t make much of a difference in your home value. Switching to solid core doors and double glazed windows may slightly improve a home’s resale value. A home theater with full acoustic panels would boost the home value the most.


  • How do you soundproof an existing wall?

There are many ways to soundproof an existing wall. However, the most popular and affordable way is to add mass and seal gaps where sound may leak through. You can add insulation into an existing wall using specialized drilling equipment.

  • How much would it cost to soundproof a wall?

The cost to soundproof a wall is $100 to $350. Acoustic panels and insulation upgrades are the most common soundproofing projects to prevent sound transmission through the wall.

  • How do you soundproof a room for music?

To soundproof a room for music, you need acoustic panels on the walls and ceiling. A solid door and acoustic door blanket produce the best room environment for making music and recording songs.

  • What is the cheapest way to soundproof a room?

One of the cheapest ways to soundproof a room is by hanging heavy curtains and tapestries on the doors and walls. The thicker the material, the better it will be at absorbing sound. Adding thick rugs and a rug pad below the carpet, installing a door sweep, and placing massive furniture against walls are other inexpensive ways to soundproof a room.

  • How can I make my room soundproof from outside noise?

External noise often enters a room through big gaps around the door. You can prevent this by installing a commercial-grade door sweep that seals against the threshold and blocks outside noise, as well as bugs and insects. Heavy blackout curtains that seal against the door help soundproof a room against external noise.

  • Are egg cartons soundproofing?

While egg cartons are inexpensive and reduce echoes and certain frequencies, they are not very effective in reducing sound. However, they are very similar in size, shape, and appearance to the soundproofing acoustic foam used in music studios, which may have given rise to the myth that you can use them for soundproofing.

  • What is Green Glue, and how does it work?

Green Glue is a noise proofing solution that turns mechanical energy from noise into heat. It creates a damping system when inserted between two layers of drywall. Green Glue is used for soundproofing walls and ceilings.
