How to Install Weatherstripping on an Entry Door for a Tight Seal

A 1/32” gap around the edge of an entry door can let in as much cold air as a two-inch hole smack in the center.  Imagine how that would feel on a wintry day.

The good news is you can eliminate drafty leaks around exterior doors with this simple-to-apply weatherstripping that installs in minutes and lasts for years.  The integrated vinyl tubing makes an excellent seal against moisture and air.

With the door closed, measure the length of the doorstop on the hinge side of the door frame.  Then, transfer that measurement to a length of weatherstripping. 

Next, draw a straight cutting line.  Cut the vinyl tubing with a utility knife and the metal with a hacksaw, using a very fine 32-tooth-per-inch blade.  Using a self-centering drill bit, drill pilot holes and then install the screws.  When the right and left sides are in place, measure and cut the top.  Attach the top piece the same way the sides.  With the weatherstripping installed, you can tell just by the sound of the closing door that it's well sealed and that drafts are going to stay outside where they belong.
