How to fix a leaking door threshold.

Simply remove the corner pad s adhesive backing and stick the small square pad to the insides of your door frame at the crucial corners. Tap it snugly into position using a rubber mallet. Now also if you take a piece of paper and lay it on the threshold how hard is it to pull out from under the door. At that point it is wise for the homeowner to simply make a purchase of a new door threshold as opposed to trying to fix it.

Lay a bead of caulk along what will be the back edge of the threshold. You most likely need to replace the gasket along the bottom of the door slab. If it prevents the door from closing comfortably you can plane down the door or lower the threshold. Slide the threshold underneath the doorstops and position the notches you cut around the door jambs.

Opportunity is missed by most people because it is dressed in overalls and looks like work. Take the door off by pulling the pins in the hinges and post a picture of what that gasket looks like. Unfortunately if the spring goes bad this system becomes useless. Give it 30 min to show up and if that doesn t work try spraying around the outside of the frame and see if it leaks in then.

Place the end of a strip of adhesive backed aluminum tape on one of the side jambs in the doorway 3 inches above the threshold. You could try a door sweep with a rain drip cap to keep water from running down the door and going inward at the bottom. Have a helper with you and on a dry week spray with a water hose against the door where it meets the jam see if any water leaks in from that. Notice how this door sweep has a rounded front edge the water will drip off of it.
