Garage Door Garage Door Seal Replacement Duncanville, TX
For garage door seal replacement in Duncanville, TX, the right approach depends on the environment. Local conditions bring summer heat and moisture that swell wood doors and seize rollers, storm-season wind that stresses panels and bottom seals, and intense UV that degrades rubber weatherstripping, which we account for on every Duncanville job.
Ask any Duncanville tech and they'll tell you the climate decides what fails. A warm, humid climate of sultry summers, abundant rainfall, and damp conditions that work hard on metal hardware brings summer heat and moisture that swell wood doors and seize rollers, storm-season wind that stresses panels and bottom seals, and intense UV that degrades rubber weatherstripping, year after year.
Run down the service log for Duncanville and the same repairs repeat: swollen, sticking wood doors in summer humidity, storm-driven debris and water in the tracks, corroded springs and cables in the humid air, and rusted bottom brackets on damp slabs. We carry every part needed to close them out in one trip.
Bottom seal replacement is the highest-volume seal job we do — bottom astragals wear out faster than the side jamb or top header seals because they contact the floor every close cycle. The seal compresses, deforms, hardens under UV, and eventually tears or cracks. A failed bottom seal lets water, dust, leaves, insects, and small rodents under the door. The fix is straightforward and quick: remove the old seal, slide a new one into the retainer (or replace the retainer if it's also worn), trim to length, and verify a tight close.
We carry T-style, P-style, and bulb-profile astragals to fit any retainer. The retainer (U-channel) is the aluminum or PVC track that holds the seal — if the retainer itself is cracked or pulling away from the bottom panel, we replace it during the same visit. Stock profiles cover 95% of doors; obscure or vintage doors may need a special-order astragal.
Fast service for stock profiles is standard. Most visits take 45–60 minutes including a quick check of the side and header seals and a confirmation of the bottom-to-floor gap with the new seal compressed.
Worn or compressed seal lets daylight through. Replacement restores the seal.
Water enters during rain
Bottom seal failure is the most common cause of garage water intrusion during heavy rain.
Leaves or debris under door
Wind blows debris under failed seals. Restored seal stops the inflow.
Insects or rodents entering
Even small gaps let pests through. A continuous seal stops them.
Seal visibly cracked, torn, or chunked
Visible damage means the seal is functionally compromised even if the gap looks small.
Common causes & what we fix
UV degradation
intense sun hardens vinyl and rubber seals over 5–8 years. Hardened seals crack and tear.
Floor contact wear
The seal compresses and abrades against the floor every close cycle. Wear is cumulative over years.
Concrete heave or settlement
Floor changes shape with foundation movement. Old seal can't compensate; new seal with potential threshold kit can.
Pest damage
Rodents chew through seals to enter. Once chewed, seal must be replaced — repair isn't viable.
Retainer corrosion or cracking
Aluminum retainers corrode at the floor contact line; PVC retainers crack with age. Retainer replacement extends seal life.
