How to replace weather stripping on your doors

Here’s a general step-by-step guide to replacing your home’s existing weather stripping. Keep in mind that weather stripping comes in many varieties, so the actual installation process may vary. Be sure to check the instructions provided by the manufacturer.

1. Remove the old weather stripping

The first step in replacing your home’s weather stripping is to remove the old one. This is usually a simple process that involves either peeling the old weather stripping off of the door or removing the screws that are holding it in place. 

If your doors don’t have any weather stripping, you can skip this step and start fresh.

2. Prep the surface

Once the old weather stripping is off, the next step is cleaning the door where the new one will be installed. This is especially important if adhesive was used before, as leftover residue can weaken the new strip’s bond.. A sponge and some soapy water should do the trick. Thoroughly dry the area after cleaning.

3. Measure and cut the new weather stripping for your doors

Once you’ve removed the old weather stripping, it’s time to install the replacement. Lay the new strip along the edge of the door and carefully measure it against the length you need. Use a utility knife or heavy-duty scissors to make clean, precise cuts. Precision is key as the strip needs to fit snugly without leaving gaps. Taking the time to cut each piece accurately will make the installation smoother and create an effective seal

4. Install the new weather stripping on the doors

With the pieces cut to size, begin attaching the weather stripping along the door frame. Some types come with adhesive backing, just peel and press firmly into place. Others may require small nails, staples, or a tension fit, depending on the style you’ve purchased. Make sure the strip is flush in corners and pressed securely along the full length.. A properly installed strip will create a seamless barrier that keeps the outside air where it belongs.

5. Test the seal to ensure a tight fit

Once the weather stripping has been installed, close your door to make sure the fit is snug and there aren’t any visible gaps. The whole point of weather stripping is to insulate your home and improve its energy efficiency, so it’s important to ensure that it’s been installed properly.
