How To Reseal Patio Doors

Patio doors are a great way to let in natural light and fresh air, but they can also be a source of drafts and heat loss if they are not properly sealed. Resealing your patio doors is a relatively simple DIY project that can save you money on your energy bills and make your home more comfortable.

Materials You'll Need

New weatherstripping
Caulk
Caulk gun
Utility knife
Putty knife
Screwdriver

Instructions

1. Remove the old weatherstripping. Use a utility knife to carefully cut away the old weatherstripping from the door frame and the door itself. Be careful not to damage the door or the frame.

2. Clean the door frame and the door. Remove any dirt or debris from the door frame and the door using a damp cloth. Allow the surfaces to dry completely.

3. Apply new weatherstripping. Cut the new weatherstripping to the correct length and apply it to the door frame and the door. Use a caulk gun to apply a thin bead of caulk around the edges of the weatherstripping. Press the weatherstripping into place and smooth it out with a putty knife.

4. Recaulk the door frame. Use a caulk gun to apply a thin bead of caulk around the perimeter of the door frame. Press the caulk into place and smooth it out with a putty knife.

5. Replace the screws. Replace the screws that hold the door frame in place. Tighten the screws until the door frame is secure.

6. Test the door. Open and close the door several times to make sure that it is properly sealed. If you feel any drafts, you can add more caulk or weatherstripping.
