Onset's garage door seal replacement jobs land on our schedule daily. The housing here is mostly suburban single-family homes with attached garages, alongside pockets of older in-town housing, and we size every fix to match it rather than forcing a one-size part.
Onset's weather writes the maintenance schedule. With warm, wet summers and cold winters with snow and ice, driving repeated freeze-thaw cycles on exterior hardware, doors here face wide seasonal swings that work bolts loose over time, spring damp that rusts unsealed cables and brackets, and doors frozen to the slab on the coldest mornings — and we stock the parts that stand up to it.
Across Plymouth County, the garage door problems we see again and again are corroded low brackets from winter slush, cold-snapped torsion springs in deep winter, openers straining against cold-thickened grease, and loosened hardware from wide seasonal swings. If that sounds like your door, there's a good chance we can fix it today.
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.

Top questions homeowners searching for Garage Door Seal Replacement near me ask us:
What's the most common garage door problem in Onset?

Both are stocked on the truck, so most repairs are one and done.

How long does a new seal last?
5–8 years for bottom seals in intense sun. Sheltered or shaded doors get 10+ years. Side and header seals last longer.
Do you also do threshold kits?
Yes — threshold kits sit on the floor and create a positive bottom seal even on uneven floors or where bottom astragal alone isn't enough. Installed flat-rate, quoted before we start.
How long does seal replacement take?
Bottom seal only: 30–45 minutes. With retainer replacement: 60–75 minutes. With side and header seals: 90–120 minutes.
Will the new seal work on an uneven floor?
Up to ~1 inch of floor variation — yes. Bulb seals compress more than T-style and handle more variation. For severe floor unevenness, threshold kit is the better solution.
