Labor Costs to Install a Sliding Patio Door

Installing a sliding patio door requires professional knowledge so that it can be installed properly, so hiring a professional to do the job is a good idea. Installing a sliding patio door includes: preparation of the opening for the new door (measuring to make sure the new door fits), applying leakproof flashing 3, caulking 4 and installing the new frame, adding extension jambs, trim, and filler strips, and then adding filling in the exterior trim to support the door.

The average cost to install a sliding patio door averages $1,400-$4,000. This price includes labor costs, which average around $65-$85 per hour and will take approximately 7 hours to install, as well as material costs including shims, silicone, and caulking 4. Removal and disposal of an old patio door typically costs $100-$150 and is included in the cost.

How to Measure for a Sliding Patio Door

If you are replacing an existing sliding patio door or installing a new door, one of the most important steps is to correctly measure for your new door so that it will fit properly. Sliding patio doors often come in standard sizes so it shouldn’t be too complicated to order a door that will fit. The typical patio door opening is 6'8" tall and 6 to 12 feet wide.

To measure your patio sliding door opening for replacement, remove the wood trim first so that you can get more accurate measurements. Measure from one top corner to the other to get the width, and measure from the top corner to the bottom corner on the same side to get the height. Take 3 width measurements at different locations and average them, and 3 height measurements at different locations and average them, and submit these averages to the contractor. Make sure you measure your sliding patio door from the inside, as the measurements will be more accurate.

This cost guide is based on installing a 6’-wide sliding patio door. It is important to keep in mind that the bigger the size of the door, the higher the cost.

Sliding Patio Door Replacement Costs

If you already have a sliding door in place, you can actually save on the overall cost of installation. Replacing an existing sliding door costs around $800 to $2,000 on average. You'll be expected to pay around $100 to $300 for removal of an old door. Additional costs of $100 to $300 may apply if the frame needs replacing or repairing.

You might also just need a panel replaced on your pre-existing door. This will cost between $400 and $700 in general, which covers the cost of removing and disposing the old panel, plus the installation of the new one.

Cost to Install a Sliding Glass Door in an Existing Wall

If you wish to install a sliding glass door into an existing wall without any kind of pre-existing door or opening, the costs will be higher on average than simply replacing a door. This kind of installation will cost around $1,500 to $5,000 on average.

The cost of creating a new opening in the wall ranges from $400 to $1,500, and then there's another $300 to $600 in costs to frame the new opening, plus the potential costs of permits and structural engineers, which can add anywhere from $300 to $1,500 onto the total price.

Right Hand vs Left Hand Sliding Door

Right hand and left hand are terms that help to determine the way in which the door will slide open.

While facing the sliding patio door, if the door handle is on the left hand, then this is considered a right-hand door. The right side of the door is fixed and the left side will slide open along the tracks. Opposite to that, if the door handle is on the right side of the door, then this is a left-hand door. The left side of the door is fixed and the right side will slide open along the tracks.

Patio Door Hardware

If you want your door handle and door frame to match the hardware styles and colors in the rest of your home then hardware is something that you will have to consider as an additional cost. A door handle and door frame cost anywhere from $20-$100 plus $30-$35 in labor fees.

For installation, a sliding patio door roller is needed and can cost between $15-$50 plus $30-$35 in labor fees.

Sliding Patio Door Lock

Locks are a very important part of the installation process of a patio door. In comparison to the past, locks for sliding doors are much more advanced and provide a much higher level of security. A basic lock for a sliding patio door averages $10-$15 and other options are available such as auxiliary locks ranging from $20-$50. Some common lock types for patio doors include deadbolts, foot locks, and security bars.

Screen for Sliding Glass Door

Having a screen for your sliding patio door is a great way to naturally cool your home, allowing fresh in while blocking bugs and dirt from entering your living space. They can help you cut down on your energy bills by cooling the property naturally, without the need for fans and air conditioning units, and they come in various styles so you can find one that suits you.

There are two main types of screens for sliding glass doors: sliding and retractable. Sliding screens are installed on the exterior of the sliders and are only located on one side of the doors. They’re cheap and affordable, with great value options available for $150 to $250, but they’re not ideal for homeowners with pets as claws and paws can damage them, leading to repair costs.

Retractable screens are becoming more and more popular with many homeowners due to their unique advantages. As the name implies, they’re able to retract into a housing chamber when not in use, letting you pull them out and store them away as needed. They can be easily installed on any patio door and are available in a range of colors and styles, as well as being more durable than sliding screens. However, they’re more expensive on average, costing $400 to $600.

Automatic Sliding Door Price

Enhance your new patio sliding door with an automatic sliding door system. Automatic sliding doors provide beauty, strength, and technology into one! Automatic sliding doors make it easy to open up with little maintenance and also provide a reduction in operational noise. Automatic sliding doors are on the expensive side and range from $2,000-$3,500 per door including installation fees.

Sliding vs Folding vs French Patio Doors

There are different styles of patio doors to choose from. The three most popular kinds on the market are sliding, folding, and French patio doors. Each of these doors differs in the way they open and in their cost. These three types of doors are discussed below and should be taken into consideration when purchasing a patio door.

  • Folding: Allow the whole wall of glass to be folded open completely along the tracks within the floor.
  • Sliding: A patio door that slides open along the tracks.
  • French: A patio door that has two door frames that open up separately (inward or outward) using the handles.



Come in many different designs

Easy access to outside without a large opening

Tend to bring in less light



Can open up the whole door completely

Easy to open

Brings in a lot of light

Frame is heavy so moving the folding panels can be difficult



Provide lots of light due to their narrow frames

No sections to fold back so saves on space

Visually cleaner

Over time they can wear out and become more difficult to open and close


Energy Star Certified Patio Doors

Due to advances in technology, ENERGY STAR certified patio doors make it easier to save energy than ever before.

ENERGY STAR patio doors offer:

  • Reduction in energy costs up to 12%.
  • Less condensation in cold weather and better protection from sun damage to furnishings.
  • Reduction of cold drafts.
  • Reduction of noise.

ENERGY STAR is a government-supported program that uses energy ratings and their U-factor to define their energy efficiency. The U-factor measures the rate at which heat transfers and how well the window insulations. The U-factor ranges from 0.25-1.25 and is measured using Btu/h. ENERGY STAR rates patio doors based on the gas between the panes, glass, spacer, and reinforcement. ENERGY STAR is managed by the EPA and the US Department of Energy.

ENERGY STAR doors are excellent for installation and provide many benefits. The only downfall comes with the cost. ENERGY STAR doors are quite pricey and range from $234-$1,050 depending on the material of the door and the brand.

Enhancement and Improvement Costs

Built-in Blinds

As an additional feature, some sliding patio doors offer built-in 5 blinds, which give your home extra elegance and beauty. There are many advantages of built-in blinds such as little maintenance, easy cleaning, energy efficiency, and reduction in noise. Patio doors with blinds can be a worthwhile investment and improvement cost. Purchasing a patio door with built-in blinds can increase the cost of the patio door considerably. A patio door with built-in blinds can raise the cost by $150-$400.

Pet Panels

Pet panels make it easy for pets to go outside and do their business when they want. Designers have created pet panel inserts that fit in any sliding patio door without any drilling. Pet panels come in a variety of sizes depending on the size of your pet and make it very convenient to let them go outside on their own time. Patio doors can be purchased with pet panels already attached or you can purchase the insert on their own. Sliding patio doors with pet panels attached range in cost from $125-$500, depending on the size, brand, and style. Pet panel inserts can be purchased separately at a cost of $54-$350.


Door grids are a beautiful enhancement option that mimics the look of a multi-paned door. Grids are often chosen based on their attractiveness and to act as an accent piece for a home. Grids often come as part of the door and increase the door value by $50-$100.

Old Door Removal

Before you can install your new sliding patio door, you will have to remove your old door. Removal and disposal of the old patio door is typically included in the project cost and averages $100-$150.


Transoms are small, detailed windows that are located over or beside a door. They are good for adding extra light, with many different styles available. Transoms are quite popular and are a great improvement choice for installing a new sliding patio door. Transoms are quite costly and range from $150-$800 per window.


Adding some sidelights to your patio door can help to enhance its appearance. There are different styles of sidelights that run along the side of the patio door or some that illuminate an entrance way. Sidelights that run along the length of the door range in price between $100-$250 each. The sidelights that illuminate the entrance way are called path lights and typically cost $75-$100 each. For installation of sidelights an electrician charges an average of $40-$100 per hour for installation.​

Additional Considerations and Cost

  • Installing a patio door in a wall where no existing opening requires some modifications to the wall, plumbing, and electrical wiring. If the wall is load-bearing then only experienced carpenters or structural engineers should decide whether it can be done and how. The cost to hire a structural engineer varies depending on a few factors. For instance, the length of time in their field will increase their price. Newly graduated structural engineers will charge between $18-$26 per hour while engineers with more experience charge from $30-$42 per hour for the same work.
  • Glass sliding doors today are much more advanced than ever before. They provide more insulation, are more attractive and overall much stronger.
  • The warranty on patio doors may differ depending on the brand. Most companies, however, offer a lifetime warranty. This usually includes a lifetime warranty on the door against warping, peeling, rotting, or cracking, on the hardware and on the glass seals.
  • Warranties do not include surface fading due to sunlight, air pollutants, and atmospheric conditions or damage from improper installation, abuse, accident, negligence, or anything else beyond their control.
  • If you are required to make any changes to the framing of your patio door, a permit may be required to ensure that the required amount of ventilation is maintained and that no safety issues arise. Pay a visit to your city or town hall to get information on the permit you may need to complete the job.
  • During a home inspection, a homeowner should be informed of any repair and maintenance concerns to a patio door. They should be informed whether there are things like rot or mold and should be given the cost to adapt the existing door-opening structure.
  • Here are a few maintenance tips to keep your sliding patio door running smoothly:
  • Clean the track and rollers once or twice a month. A lot of dirt and grime get trapped in the bottom and can make it difficult to open up the door.
  • Replace the seal if it becomes torn, cracked, or broken. This will keep all of the dust and dirt out.
  • If your screen door 6 becomes damaged over time and constantly falls out then it is a good idea to replace it.
  • If you are looking to replace your sliding glass door you should do it in good weather. Once you remove the old door, your inside will be exposed to outdoor elements until the new door is put in place.
  • If you experience any issues with the flooring, siding, or interior trim due to rotting, water damage, or other reasons, this can add to the final cost. The cost of floor repairs is dependent on the size of the space and can range from $140-$850. If there are any issues with the siding the average cost to repair siding is $300. If there are any issues with the interior trim, it averages $155 to repair the trim.
  • Removing a sliding patio door can be challenging but successful with the use of the right tools. First, the interior casing and trim is removed with a screwdriver. Once the casing and trim is removed, the sliding door panel is lifted out. The stationary panel for the sliding door is then removed. After the panel has been removed the exterior trim needs to be pried off. Lastly, the door jamb needs to be cut away so the door can be removed. This can be a DIY project, however, it can be timely and challenging on your own.
