How much does it cost to install weatherstripping?
A poor air seal around your windows and doors could be losing you as much as 20% of the energy you use to heat and cool your home according to Energy Star. This poor air seal can be caused by swelling or shrinking of frames creating openings, or simply by a door or window not being sized perfectly to your home. One of the most recommended and effective ways to stopping an air gap is to weatherstrip your home, or to apply a type of foam, rubber, or metal material around the gaps in your windows and doors, as well as in areas such as your attic to stop the transfer of air in and out of your home.
Weatherstripping your home is easy, and many people choose to take on the project themselves, while others may hire a handyman to take care of the job for them. The average cost of weatherstripping a home is around $168 using a variety of materials to fill the relevant areas all over your home.
When to weatherstrip
If you suspect that your home will benefit from weatherstripping, it probably will. Feeling cold air or drafts near windows and doors is an indication of a poor air seal that could be improved with the use of weatherstripping. Energy Star makes a DIY guide to air sealing your home that includes additional steps you can take to determine whether or not an area of your home could be sealed. They recommend starting in either the attic or basement and working your way through your whole home. However, even the most thorough search by a homeowner often misses places. Therefore, it is recommended that you have a professional check your home, to determine how much weatherstripping should be done.
How to choose weatherstripping
With so many options on the market and on the shelves at the home improvement store, it can be difficult to determine which type of weatherstripping you need. These tips may help:
- Choose a weatherstripping based on the material your door or window is made of.
- Choose a weatherstripping based on the area of the door or window you are treating.
- Consider the cost vs. longevity. For example, felt is the least expensive type of stripping, but it only lasts two years, while silicone can last up to 10 for only a few dollars more.
- Ask your installer to purchase the materials for you, while there is a higher cost associated with this, around $235 total, it relieves you of the burden of choosing the right materials for each area of your home.
Types
In addition to the various applications for weatherstripping, most materials also have several pros and cons that can help you determine which one will be right for your project.
| Material | Pros | Cons |
|---|---|---|
| V-Tape/Tension Seal | Easy to use Comes in a roll of adhesive backed tape that you press into place Can be used on many types of windows and doors | Thin Won’t seal up large cracks or heavy doors |
| Felt | Inexpensive Easy to use Works on nearly all types of windows and doors | Only lasts about 2 years before it needs to be replaced |
| Reinforced Foam | Easy to use Comes on a roll with an adhesive back | Doesn’t last as long as some types Can only be used in thicker gaps and doorways |
| Door Sweeps | Easy to install | Rubber sweeps can crack over time |
| Magnetic | Forms a very good Close seal, particularly on aluminum doors and windows | Harder to install |
| Tubular Rubber and Vinyl 1 | Lasts a long time Makes a good seal on nearly all types of doors and windows | Difficult to install, as the tubular form is round and rolls as you put it up |
| Rolled and Reinforced Vinyl 1 | Lasts a long time Makes a tight seal on most types of doors and windows | Can be difficult to install Must be nailed in place |
| Reinforced Silicone | Lasts a very long time Can be used in place of caulk 2 in some outdoor applications | Expensive Hard to work with |
| Door Shoe | Lasts longer than door sweeps | Fits over the bottom of the door Not as adjustable for finding the right fit |
| Bulb Threshold | Works well at stopping heat and cold transfer | Difficult to install Needs special threshold tools |
| Frost Break | Very effective at stopping cold transfer | Very difficult to install Needs threshold tools |
| Fin Seal | Ideal for aluminum windows and sliding doors | Limited in its use If you have mixed material windows and doors, you can’t use this material on anything but aluminum |
| Interlocking Metal Channels | Locks up door perimeters securely | Hard to install Tight tolerances for installation |
Factors affecting the cost
Most people pay around $168 to have their home weatherstripped, but some may pay upwards of $250. There are a few factors that can go into determining what your final costs may be:
Location
There are several areas in and around your home that may require weatherstripping, and each of these areas may require a different type of material or seal depending on what it’s made of, and how big the gap is. For example, a poorly hung door with a wide gap at its top edge will require a heavier, more substantial weatherstripping than a window with a thin gap around its edge.
Most weatherstripping is sold by the roll or by the piece, depending on what it is and where it’s needed. Your installer can help you determine how much you need of each material based on the size of each area.
| Location | Type of Weatherstripping | Cost of Material |
|---|---|---|
| Sliding windows 3 | V-Strip | $12/kit |
| Doors and window sashes | Felt | $6/roll |
| Top and bottom of window sashes | Foam tape | $8/roll |
| Wide door gaps | Foam tape | $8/roll |
| Bottom of door | Door sweep | $12/piece |
| Bottom of door | Door shoe | $15/piece |
| Bottom of door | Bulb threshold | $15/piece |
| Bottom of door | Frost break | $18/piece |
| Base of doors and windows | Rubber or silicone | $10/piece |
| Garage Doors | Rubber panels | $9/piece |
Type of doors and windows
In addition to the location of the area you need to weatherstrip, the type of door or window may play a role as well. For example, sliding windows 3 will need V-stripping or tension stripping, while window sashes can use felt or foam. In most cases, weatherstripping can be interchangeable between different areas. However, there are a few types of doors and windows that need a specific type of weatherstrip to do the job.
| Type of Area to Seal | Material for Weatherstripping |
|---|---|
| Inside double-hung and sliding windows 3 | V-tape or tension seal |
| Door and window stops, as well as top and bottoms of doors and windows | Reinforced foam tape, vinyl 1, or magnetic stripping |
| Inoperable windows, irregularly shaped cracks, window sashes, and attic trap doors | Foam tape or rubber |
| Bottoms of doors | Door sweeps, door shoes, frost breaks, or reinforced silicone |
| Aluminum windows and sliding doors | Fin seals |
| Door perimeters | Interlocking metal channels |
Installation and labor
The process of weatherstripping doors and windows are relatively alike. In most cases, the material is cut to fit the opening it is being applied to. Any adhesive backs are removed and the material pressed into place. Nails are then used to help adhere the material if necessary.
Most handymen can take this job on, with an average cost of $153 for the labor; weatherstripping material itself is very low cost, making the labor the bulk of the expense.

Energy Audit
The best way to determine what parts of your home need to be sealed is to have an energy audit done. Most energy companies, including your electric company, perform this service for free. In other cases, there may be a charge up to $150, which is applied toward any improvements you make later on. An energy audit looks at all the ways your home may be losing energy, including poor air seal, using thermal imaging tools to show you the hot and cold spots in your home. Getting an energy audit done first can help you determine if you need to weatherstrip, if you need more than weatherstripping, or if your home is already well sealed.
Additional considerations and costs
- According to Energy Star, weatherstripping alone can reduce your heating and cooling bills by 20%, while at the same time reducing drafts that can make you uncomfortable.
- To figure out the amount of weatherstripping you need, measure the perimeters of your windows and doors inches and add them up. Add 10% extra for waste and error and round up to the nearest roll size.
- Weatherstripping types range from simple to difficult to install; check the guidelines on each type as you purchase to avoid confusion.
- Apply the stripping to clean, dry surfaces in temperatures above 20ºF.
- Measure twice before cutting your stripping to get the best fit.
- Inspect your weatherstripping and caulking 2 each year prior to winter to make sure they are in good condition.
- Have caulking 2 applied to any outside gaps when you weatherstrip to get the best seal. Silicone outdoor caulk 2 costs around $20 a tube, and most handymen can apply it for an additional charge of $50.
- Many types of weatherstripping can be applied DIY; check the instructions before you begin to see if the type you are using qualifies.
