How to Weatherproof a Wooden Front Door

Updated February 21, 2017

Wooden doors are energy-efficient and naturally attractive. A well-stained wooden door adds interesting decor to a house. However many of these doors are exposed to the elements. It does not matter if you have a storm door or screened door in front of it; sunlight will still reach it, particularly if it faces south. Weatherproofing is a simple project that takes only a few hours and extends the door's life.

Remove the door from the door frame, using the power drill and Phillips-head drill bit. Place the door on a flat surface, preferably raised. Sand the door to rough the surface; do not apply too much pressure. Wipe the door with the wet sponge to eliminate dust.

Apply the polyurethane with the foam brush, using long strokes and following the wood grain. Allow to dry.

Remove the weatherstripping from the package. Measure the door frame on both vertical sides and the top horizontal side, using the tape measure. Cut the weatherstripping into the proper lengths, using scissors.

Remove the backing from the weatherstripping and place against the door frame on the top part of the door jamb. Start on the left side of the door first, then the top, and finish on the right side.

Hang the door with the screwdriver after the door has dried. Make sure that the door opens and closes smoothly. If it does not, tighten the screws to the door jamb a bit more.


Allow yourself at least 24 hours of good weather.


Wear surgical gloves to keep the polyurethane off your hands.
