Garage Door Garage Door Seal Replacement Alton, IL

In Alton, every garage door seal replacement starts with the local picture — warm, wet summers and cold winters with snow and ice, driving repeated freeze-thaw cycles on exterior hardware. We choose hardware that survives Illinois's continental-climate region, not whatever's cheapest on the shelf.

What wears out a Alton door isn't just use — it's the weather. Warm, wet summers and cold winters with snow and ice, driving repeated freeze-thaw cycles on exterior hardware drives freeze-thaw cycles that crack seals and loosen hardware, wide seasonal swings that work bolts loose over time, and cold-thickened opener grease that strains the motor, and we plan for all of it.

Garage doors in Alton tend to fail in predictable ways — cold-snapped torsion springs in deep winter, humidity-swollen wood doors in summer, corroded low brackets from winter slush, and rusted hardware from snowmelt and road salt. Catching them early during a tune-up usually costs a fraction of an emergency call.

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.

Signs you need garage door seal replacement

• Visible gap between closed door and floor

  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.
