Sometimes doors can become problematic, and having a perfect seal is important, especially when friends and family are inside. Visible light, cold air drafts and even leaky doors are all tell-tale signs that your door sill may need adjusting.
In this project guide, adjusting your sill is made easy with our step-by-step video that teaches you how to adjust your adjustable sill. From removing the cap plugs to testing the cap height, we’ve got you covered. Let’s get started!
b. Use the putty knife to pry the cap plugs up and away from the cap.
Not sure which way to go?
• If you can see light, or feel air under your door panel, you need to raise your cap by loosening screws.
• If it is difficult to open and close your door panel, you may need to lower your cap by tightening the screws.
b. Readjust the cap as necessary:
• If the door is too hard to close, you may need to tighten the screws to lower the cap.
• If the door is too easy to close and there is no compression of the door bottom, you may need to loosen the screws to raise the cap slightly.
b. Align with weatherstrip and door jamb based on the strike margins (distance between door panel and side frame on the strike side):
• If the margins are less than 5/32`` (tight), align with the weatherstrip kerf.
• If the margins are 5/32`` or greater, align with interior side of door jamb.
c. Press firmly into place.
