Our garage door seal replacement service covers all of Sanbornville: Wakefield Village and Milton Mills. Set in New Hampshire's continental-climate region, these doors face winter snow and ice load on doors and tracks, humid summers that seize hinges and rollers, and wide seasonal swings that work bolts loose over time, and we plan every repair around it.
Sanbornville, NH is shaped by a humid continental climate — hot, humid summers and cold, snowy winters, with sharp freeze-thaw swings between seasons. We've learned which parts last in New Hampshire's continental-climate region, because winter snow and ice load on doors and tracks, humid summers that seize hinges and rollers, and wide seasonal swings that work bolts loose over time take a steady toll on springs, tracks, and seals.
Nine out of ten Sanbornville calls trace back to ice- and snow-jammed tracks, loosened hardware from wide seasonal swings, humidity-swollen wood doors in summer, and corroded low brackets from winter slush. We pinpoint which one it is before quoting a cent.
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.

Frequently asked about garage door seal replacement
Top questions homeowners searching for Garage Door Seal Replacement near me ask us:
Do you cover the whole Carroll County area, not just Sanbornville?
Yes. Sanbornville is one of the communities of Carroll County, New Hampshire, and we work the whole footprint: Sanbornville plus nearby Rochester, Somersworth, Laconia, and Dover. Same licensed, insured crews and 10-year workmanship guarantee county-wide.
How does the climate in Sanbornville, NH affect my garage door?
Sanbornville sits in a humid continental climate — hot, humid summers and cold, snowy winters, with sharp freeze-thaw swings between seasons. That is hard on a door — winter snow and ice load on doors and tracks, humid summers that seize hinges and rollers, and wide seasonal swings that work bolts loose over time all accelerate wear on springs, seals, and openers, so the failures we see most here are ice- and snow-jammed tracks, loosened hardware from wide seasonal swings, humidity-swollen wood doors in summer, and corroded low brackets from winter slush. We size springs and seals for New Hampshire's continental-climate region conditions rather than a generic catalog spec.
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.
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.
What seal profile do I need?
T-style (most common since 1990s), P-style (older builds), or bulb (commercial and some specialty). We bring samples to the visit so you can see and feel the options.
