How do I adjust the threshold on my front door?
Raise the threshold where light enters by turning the nearest screws counterclockwise. Set a straightedge (such as a framing square) on the threshold and adjust the other screws to make sure the adjustable strip is straight. Close the door and check for light. Readjust the threshold until you’ve eliminated the light.
What can be used to adjust the threshold of the door?
Use a Phillips screwdriver to raise or lower the threshold. Turn the screws counterclockwise to raise the threshold and clockwise to lower it.
How does a door threshold work?
When properly fitted, the threshold under an exterior door keeps water and air from drifting in from outside. The threshold should fit against the door snugly enough to keep the elements out but be loose enough to allow the door to open and close freely without binding against and wearing down the weather stripping.
How do you seal a door threshold?
Attach the weather strip to the center of the threshold. Use a thin layer of silicone caulk to help form a tighter seal. The caulk will need to be applied to both the underside of the threshold and the underside of the weather strip material. Allow plenty of time for the caulk to dry before you test the door.
