Replacing the weatherstripping at the bottom of a door is a simple and inexpensive way to improve the energy efficiency of your home, reduce drafts, and keep out pests. Weatherstripping is a thin, flexible material that is installed around the edges of doors and windows to create a tight seal and prevent air and moisture from leaking in or out.
There are many different types of weatherstripping available, but the most common type for bottom of doors is a vinyl or rubber seal. These seals are typically self-adhesive, making them easy to install. To replace the weatherstripping on the bottom of your door, simply remove the old seal and clean the area where the new seal will be installed. Then, peel off the backing of the new seal and press it into place.
