Have things been getting a little drafty in your home? It may be time to replace the weather stripping on your doors. This type of exterior door maintenance won’t just make your living space more comfortable—it’ll also save you cash. Fewer drafts equal lower energy bills, and you don’t need to be a pro to get it done. Here’s how to replace worn weather stripping around doors in just 60 minutes.
Sealing gaps and weatherstripping can save up to 20% in annual energy bills according to the U.S. Department of Energy.
Inspect Your Door
Before you start your project, you’ll want to inspect your weather stripping and tighten the hinges on your door. The goal is to make sure that your weather stripping—rather than a loose hinge—is actually what’s causing a draft. If you can lift your door up by the knob, your hinges may be to blame.
Once you rule out the hinges, measure your space. Close the door and measure the areas where you want to install your replacement weather stripping along the door jambs. Both width and length are important. For example, you’ll often need a thicker type of weather stripping for garage doors.
When in doubt, you can measure your existing weather stripping for reference as long as it’s not significantly degraded. Door sweeps, which go on the bottom of the door, come in standard sizes. After you take your measurements, add 10 inches to the length to give yourself some leeway.
Remove Old Weather Stripping and Clean the Area
Remove your old weather stripping either by hand (if it’s peel-and-stick) or by removing the screws and nails that hold it in place. If you’re having trouble pulling it away from your door, use a putty knife to get under the adhesive.

Cut Your Weather Stripping

One for the horizontal jamb (the interior top of your door frame)
One for each vertical jamb (the interior sides of your door frame)
Use your tape measure to determine the right size, then use scissors to make your cut. Keep the length a little longer than required to fine-tune it later. It’s better to have a piece that’s too big than too small. Hold your weather stripping segments up to the door frame to check the sizing.
Install the Weather Stripping

If needed, cut the excess weather stripping to get a perfect fit. Press it down firmly to ensure adhesion, and—if you want added security—tack it in place using a staple gun or small nails.
Install the Door Sweep
Door sweep weather stripping goes on the bottom of your door rather than the door frame. Some varieties are adhesive. Others need to be screwed into the bottom of your door. Either way, when you install the door sweep, make sure there’s a tight seal along the threshold (bottom of your door frame). This prevents draft.
Types of Weather Stripping
There are different types of weather stripping, but most homeowners choose a self-adhesive variety because it’s simple to install. However, the material you choose matters.
Felt or foam varieties, like foam tape, are some of the most popular kinds of self-adhesive weather stripping. These can lack durability, despite their ease. If you’re installing weather stripping on an exterior, you may want to choose something stronger like a self-adhesive v-seal or tension seal weather strip made from vinyl, bronze, aluminum, or stainless steel. Rubber is one of the most durable options, but installation is tricky because you’ll need to nail it in place, so you may want to hire a local handyperson.
When purchasing new weather stripping, consider:
Where it’s going on your door
How much durability you’ll need
Your overall budget
Your climate
DIY vs. Hiring a Pro to Replace Weather Stripping
You can save more than $100 on the cost of weather stripping if you install it yourself. This is no problem for most DIYers—especially if you’re using self-adhesive weather stripping. Some varieties, like tubular rubber, are more difficult to install because they need to be nailed into place. In that case, you may want to enlist a local handyperson service. If the project extends to more than just a single door, you may want to have a handyperson weatherize your whole home.
Cost to Replace Weather Stripping on a Door
The average cost to replace the weather stripping on a door is $280, but it can range from $60 to $930, depending on the size and type of your door. The cost to have weather stripping replaced can range from $1.45 to $25 per linear foot. However, about 80% of the cost to replace weather stripping is labor, so you can save a considerable amount by tackling this project yourself.

Weather stripping can be installed to the door or door frame, depending on the type of door you have. Weather stripping is typically applied to the door frame, which will have a small groove or opening to fit the weather stripping into. But if you have a very old door, the frame may not have this opening, in which case you’ll need to purchase a special type of weather stripping that is meant for door installation.
