Garage Door Gap Repair in Portland, ME
A gap under or around your garage door means cold air, rain, snow melt, and whatever lives outside all have an open invitation. The bottom seal is the most common failure point — it's a rubber or vinyl strip that takes a beating from the floor, UV, and repeated compression. Side and top weatherstripping fail too, usually from the door rubbing against the frame due to minor settling. We identify where the gap is coming from and whether it's a seal problem, a framing problem, or a door alignment issue.

When to Call
When You Need Garage Door Gap Repair

- The garage smells like exhaust because fumes are drifting in from outside
- Mice got in and the only apparent entry point is under the door
How It Works
Our Process for Garage Door Gap Repair
- 1
Gap Mapping
We close the door and check all four sides with a light behind it — gaps show up clearly and tell us where the seal or alignment is failing.
- 2
Cause Identification
A gap from a worn seal is different from a gap caused by a sagging door or uneven concrete floor. We determine which problem we're actually solving.
- 3
Seal Replacement or Adjustment
Bottom seals, door stops, and weatherstripping are replaced with the correct profile for your door type and threshold condition.
- 4
Alignment Correction if Needed
If the door itself sits crooked in the opening, we address the track or spring balance causing it before the new seal goes in.
Portland Context
Why this matters in Portland
Portland's combination of hard winters and wet springs means garage gaps don't stay minor for long — water intrusion along the bottom seal can damage concrete, rot wood thresholds, and freeze into ice dams that crack the seal further. Coastal homes near Munjoy Hill deal with wind-driven rain that makes side seal gaps a real problem.
Straight Talk
About pricing & scope
A simple bottom seal swap is quick work. If the floor is uneven or the door frame has shifted, that changes the scope — some gaps can't be fixed with just a new seal strip. We'll be straight with you about which situation you're in.
