How-To Address a Sagging Door

Therma-Tru provides a simple tutorial on where to look first for a sagging door issue. The most common sagging issues with a door occur because the wrong screw lengths were used to hold up the hinge. If the door continues to sag after correcting the screw length issue, Therma-Tru recommends contacting a local contractor.
