Garage Door Garage Door Seal Replacement Concord, NH
For garage door seal replacement around Concord, the details that matter are local: winter snow and ice load on doors and tracks, summer heat and humidity that swell wood doors and rust steel, and wide seasonal swings that work bolts loose over time. Our crews stock corrosion-resistant parts built for exactly those conditions.
Because Concord has a humid continental climate — hot, humid summers and cold, snowy winters, with sharp freeze-thaw swings between seasons, the doors here age differently than inland or coastal homes elsewhere. The usual culprits are winter snow and ice load on doors and tracks, summer heat and humidity that swell wood doors and rust steel, and wide seasonal swings that work bolts loose over time — exactly what our techs come prepared for.
We've fixed thousands of doors around Merrimack County, and the pattern holds in Concord: loosened hardware from wide seasonal swings, freeze-thaw-cracked bottom seals, ice- and snow-jammed tracks, and warped or sagging panels after years of freeze-thaw. None of it should leave you without a working garage for more than a day.
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.
