Garage Door Garage Door Seal Replacement Longmont, CO
Longmont garage door seal replacement, done by a crew that works this area daily. We see cold-snapped torsion springs in deep winter, debris-blinded safety sensors, frozen, sluggish openers in unheated garages, and doors iced to the slab on cold mornings most often here, and we carry the parts to resolve them on the first visit.
Weather matters more than most Longmont homeowners expect. Local conditions — a high-elevation mountain climate — cold, snowy winters, dry, mild summers, and large elevation-driven temperature swings — drive heavy snow load and ice on doors and tracks, freeze-thaw that cracks seals and loosens hardware, and pine debris and grit fouling rollers and sensors, so we recommend hardware and seals suited to Colorado's high country.
The short list of what goes wrong on Longmont garage doors: cold-snapped torsion springs in deep winter, debris-blinded safety sensors, frozen, sluggish openers in unheated garages, and doors iced to the slab on cold mornings. Whatever's on yours, the diagnosis is free on most repairs and the quote is in writing.
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.
