How should weatherstripping and bottom seals on garage doors be maintained?

Garage door weatherstripping and bottom seals should be inspected regularly for cracks, gaps, hardening, or sections pulling away from the door. Since these seals are exposed to sunlight, moisture, changing temperatures, and daily movement, normal wear can be difficult to prevent. Keep the seals and surrounding surfaces free of dirt and debris, and check that the bottom seal makes even contact with the garage floor.

If you notice drafts, moisture, pests, daylight around the door, or visible damage, have a garage door professional inspect the seals. They can determine whether an adjustment or replacement is needed and check for other issues affecting how the door closes.
