Why Bottom Seals Wear Out in Montgomery's Climate
Montgomery's mix of hot summers, heavy seasonal rain, and intense UV exposure puts steady stress on garage door bottom seals. Rubber and vinyl seals harden and crack faster when repeatedly exposed to direct sunlight and temperature swings, and long stretches of humidity can cause the material to soften, warp, or separate from its retainer track.
Over several years, this wear shows up as flattened edges, gaps under the door, or sections of seal that no longer sit flush against the garage floor. Left unaddressed, a worn seal can let water pool near the base of the door, encourage pest entry, and reduce how well the garage holds a stable temperature.
Signs Your Bottom Seal Needs Attention
Sun exposure and age can cause the rubber to crack, split, or flake along its length, which breaks the seal against the floor and allows air and moisture to pass through.
If you can see light coming through underneath the closed door, the seal is likely compressed, torn, or pulling away from the panel and no longer forming a barrier.
Puddles, dirt, or leaves collecting just inside the door after rain often point to a seal that no longer forms a tight barrier against the floor threshold.
Gaps from a worn seal give insects and rodents an easy entry point and can let in noticeable drafts during cooler months, affecting the comfort of the garage space.
A seal that has slipped out of its retainer track or bunched to one side usually needs to be reseated or replaced before it causes further damage to the door bottom.
Quick Checklist: Inspecting Your Bottom Seal
Repair or Replace: What Fits Your Situation
Seal Replacement Only
If the door itself opens and closes evenly and the track is straight, replacing just the bottom seal is often enough to restore the barrier against water and pests entering the garage.
Seal Plus Threshold Adjustment
When the garage floor is uneven or sloped, a new seal paired with a threshold piece can help close persistent gaps that a seal alone won't fully address across the door's width.
Broader Door Inspection
If the seal wears unevenly on one side, it can signal a door that is out of alignment, which is worth having checked and corrected alongside the seal replacement itself.

Maintaining a New Seal Once It's Installed
After a new bottom seal is installed, a light coat of garage door lubricant on the tracks and rollers can help the door continue closing evenly, which keeps pressure on the seal consistent across its full width.
Periodically clearing leaves, dirt, and debris from the floor threshold also helps the seal maintain full contact and reduces the chance of premature wear during Montgomery's humid months.
