Weather Stripping & Seals in Sandwich, NH: Stop the Drafts Now
7 min read
In our years serving Sandwich, we've seen this problem again and again: homeowners ignore worn weather stripping until winter arrives and cold air pours into their garage like a sieve. A failing bottom seal and threshold don't just waste energy.they let pests in, damage stored items, and force your heating system to work overtime. The fix is straightforward, affordable, and something we can handle the same day you call.
Why Weather Stripping Fails in Sandwich's Harsh Climate
New Hampshire winters are relentless. Temperature swings from below zero to mild days stress rubber and foam seals constantly. UV exposure during summer, moisture from spring melt, and salt spray off treated roads all accelerate decay.
Most weather stripping materials last 5,7 years before they crack, compress, or shrink. If yours is original equipment on an older door, it's almost certainly past its prime. The bottom seal takes the worst beating.it bears the full weight of the door, flexes with every cycle, and sits closest to standing water and road salt.
Even a small gap.just a quarter-inch.creates noticeable draft and energy loss. Multiply that across a garage door that opens and closes 10+ times daily, and you're bleeding heat (and money) every single day.
Signs Your Seals Need Replacement
Visible cracks or chunks missing from rubber or foam are obvious red flags. So is a bottom seal that no longer sits flush against the floor.
Look for light showing under the door when it's closed. Run your hand around the perimeter.feel cold air creeping in? That's a draft you can't ignore. If you notice pest droppings, insect activity, or moisture buildup inside the garage, compromised seals are usually the culprit.
Some homeowners don't realize they have a problem until they see their heating bill spike or notice frost building up inside on cold mornings. By then, the damage has been done for months.

The Right Materials Make All the Difference
Not all seals are created equal. Cheap foam compresses and becomes useless within a year. Quality rubber and EPDM compounds resist temperature extremes and maintain flexibility year-round.
The threshold.that metal or rubber strip at the base.must be rigid enough to support the door but sealed properly where it meets the frame. Installation matters as much as material. Misaligned seals create gaps that defeat the whole purpose.
At Sandwich Garage Doors, we don't cut corners on materials. We install seals and thresholds that stand up to New England winters and actually last. We measure, fit, and secure everything so there's no gap for cold air or pests to exploit.
What to Expect: Cost and Timeline
A complete weather stripping and seal replacement typically runs $150,$400, depending on your door size and condition. It's one of the most cost-effective upgrades you can make. Most homeowners recoup that investment in reduced heating bills within one or two winters.
The job takes 1,2 hours. We can often fit you in the same day you call. We'll remove the old material, clean the frame thoroughly, install new seals precisely, and test the fit before we leave. No surprises, no callbacks.

Energy Savings Add Up Fast
Proper weather stripping doesn't just feel better.it performs. A well-sealed garage door reduces air infiltration by up to 80%. That means your heating system doesn't have to work as hard, and conditioned air stays where it belongs.
If you heat your garage or have living space above it, the difference is even more dramatic. Many homeowners report noticeable comfort improvements within days of a seal replacement. Use our energy savings calculator to estimate your potential savings based on your current setup.
When to Replace vs. Repair
Small cracks in rubber can sometimes be sealed with caulk, but that's a temporary fix. Once seals begin to fail, replacement is the only lasting solution. Trying to extend the life of deteriorating seals often costs more in wasted energy than the replacement itself.
