![]() ![]() Measuring and Cutting the New SealĪs long as the old seal was properly fitted to the door, we can use it as a guide to cut the new one. It’ll come in handy as a template for measuring the new seal. ![]() You may find, however, that you have some nails or staples that you need to pry away and remove.ĭon’t throw the old seal away just yet. If it’s a kerf seal - one that affixes to the underside of the door with a fin (spline) inserted into a carved-out slot - it should come away easily. You should be able to detach the old seal by simply pulling it away from the door but you might need a putty knife or a screwdriver to help dislodge it. To work on the door, I’ll just turn it on its side and lean it against the door jamb. ![]() With the hinge pins out, gently pull the door away from the hinges. Tap the underside of the hinge pins with a nail or small punch to push them up to the point where you can grab ahold of them with a pair of pliers.

The sweep comes with pre-cut slots that will give you some room for vertical adjustment. These are convenient but aren’t the greatest long-term solution, especially in severe climates because cold weather causes the adhesive to become brittle and lose its grip.

This adjustment alone could fix an air leakage or bug problem. The objective is to position the threshold so that it comes into proper contact with the bottom door seal. By turning the screws clockwise, you lower the threshold by turning them counterclockwise, you raise it. Most thresholds have four Phillips-head screws that you can turn to raise or lower the placement. This step is to ensure that the threshold is sitting at the correct level. Any issues with the subfloor really need to be addressed in a timely manner, but that’s a bigger project and a topic for a separate discussion.Īssuming that your threshold is sound, the next pre-install thing to check is its adjustment.
