Why Pests Get Through Garage Door Gaps
A garage door is built to seal tightly against its frame and the floor beneath it, but that seal can degrade over time. Weatherstripping along the bottom edge dries out and cracks, side seals pull away from the frame, and panels can warp slightly with heat and humidity — all of which create small gaps.
In Tallahassee, FL, seasonal humidity and temperature swings can accelerate wear on rubber seals and wood trim, making gaps more common than in drier climates. Once a gap forms, it tends to widen gradually rather than appear suddenly, so many homeowners don't notice it until pests or debris start showing up inside the garage.
Common Causes of Garage Door Gaps
Several separate issues can create the openings that let pests through a garage door.
The rubber strip along the bottom of the door hardens, cracks, or shrinks over time, leaving a gap along the floor even when the door is fully closed.
If the tracks are bent or out of alignment, the door may not sit evenly against the frame, creating uneven gaps on one or both sides.
Wood or composite panels can warp slightly with moisture and heat, pulling away from the frame and opening small gaps along the edges.
If the garage floor has settled or shifted, the door's bottom seal may no longer make full contact across the entire width of the opening.
Seals along the sides and top of the door frame can tear or come loose, leaving openings pests can squeeze through even when the door itself operates normally.

Options for Addressing Garage Door Gaps
Depending on what's causing the gap, a few different approaches may help.
Seal Or Weatherstrip Replacement
If the bottom or side seals are worn, replacing the weatherstripping is often the most direct way to close gaps without further work on the door itself.
Track And Alignment Adjustment
When gaps come from a door that sits unevenly, adjusting or realigning the tracks can help the door close flush against the frame again.
Panel Or Hardware Repair
If warped panels or damaged hardware are the source of the gap, repairing or replacing the affected section can restore a tighter fit along the frame.
When to Have a Technician Take a Look
Small gaps can sometimes be addressed with a seal replacement on their own, but if the door itself is out of alignment, sagging, or reacting slowly, the underlying issue is worth having checked before pests become a recurring problem.
A technician can inspect the seals, tracks, and door balance together, since gaps are often the result of more than one factor working against each other over time.
