How Weather Stripping & Seals Stop Drafts in Newmarket, NH (And Save You Money)
2026-09-13
Here's what most homeowners don't realize about weather stripping and seals: they're doing far more than just blocking a little breeze. A worn bottom seal or deteriorated threshold lets conditioned air escape, forces your heating system to work harder, and can cost you hundreds annually. In Newmarket and the surrounding areas, where winters bite hard, a single gap around your garage door is like leaving a window open all season.
The difference between a sealed door and a drafty one often comes down to whether you notice the problem before it becomes expensive. See our guide on garage door cost & pricing in newmarket, nh: an honest breakdown.
What Weather Stripping & Seals Actually Do
Weather stripping and seals create a barrier between your garage interior and the outside air. The bottom seal is the workhorse here. It compresses against the concrete floor as your door closes, forming an airtight contact. When that rubber degrades, even slightly, cold air and moisture seep in. You'll see it in higher heating bills, condensation on vehicles, and temperature swings that feel uncontrollable.
A proper threshold and complete seal system do three things at once. They reduce energy waste by preventing draft infiltration. They protect stored items from temperature fluctuations and humidity. And they keep pests and water out of your garage space. Most homeowners only think about the first benefit, but the other two save real money and headaches over time.

Signs Your Seals Are Failing
Visible cracks, hardening, or gaps in the rubber are the obvious tells. If you see daylight under the door when it's closed, your bottom seal is compromised. You might also notice cold spots near the door in winter or warm air escaping in summer. Some people describe a whistling sound or feel a draft near the threshold even when the door is shut.
One simple test: run your hand along the bottom of the closed door from the inside. If you feel moving air, the seal has lost its compression. That's your signal to call us.

How Often Do They Need Replacement?
Weather stripping typically lasts 5 to 7 years in a New Hampshire climate. Our winters, salt trucks, and freeze-thaw cycles are tough on rubber and weatherproofing materials. Some homeowners stretch them to 8 years if the door isn't used heavily. After that, degradation accelerates and energy loss compounds.

Installation and Material Quality Matter
Not all seals are created equal. Cheaper rubber hardens faster and loses compression quickly. Quality materials stay flexible longer and maintain their grip against the door's bottom. When we install new weather stripping, we measure twice and use proven products that hold up to our seasonal extremes.
The threshold itself needs attention too. If it's cracked, settling, or misaligned, even a brand-new seal won't perform correctly. Sometimes we need to repair or replace the threshold alongside the seals. That's why a proper estimate always includes both components.

Frequently Asked Questions
How long does a weather stripping installation take? Most jobs are finished in 2 to 4 hours. We remove old seals, clean the surface, and install new material carefully. If the threshold needs repair, add another hour.
Can I replace weather stripping myself? You can, but it's easy to misalign seals or miss gaps. Improper installation means wasted money. Professional installation ensures proper compression and full coverage, protecting your investment.
What's the difference between a bottom seal and side seals? Bottom seals compress against the floor and handle the most wear. Side seals run up the jambs and seal lateral gaps. Both matter, but the bottom takes the heaviest beating.
Will new seals reduce noise from outside? Yes, somewhat. They dampen sound transmission, though they're not soundproofing. The main benefit is energy efficiency and air tightness.
Do I need to replace seals if I'm getting a new garage door? New doors come with seals installed. But if you're keeping an older door, fresh seals are one of the best maintenance investments you can make.
