Weather Stripping & Seals in Somerville: Stop Drafts Before Winter
2026-04-23 7 min read
If you've noticed cold air seeping under your garage door or felt a draft while parking your car, your weather stripping and seals are likely worn out. Replacing them is one of the cheapest, fastest fixes you can make.and it prevents expensive problems down the road. Most Somerville homeowners don't realize how much heat and energy they're losing until they feel that chill or see their electric bill spike.
Why Weather Stripping Fails (And Fast)
Your garage door's weather stripping and seals take a beating. They're exposed to freeze-thaw cycles, UV rays, moisture, and constant compression every time the door opens and closes. In a New England climate like ours, rubber and foam degrade even faster.
I've seen seals that looked fine from above but had massive gaps underneath. The bottom seal especially.that critical piece that sits against your concrete threshold.gets pinched, cracked, and flattened over just 3 to 5 years of use. Once it fails, you're inviting drafts, pests, water intrusion, and energy waste into your garage.
The worst-case scenario I've encountered? A family in Somerville ignored a deteriorating bottom seal for two winters. Water pooled inside their garage, damaged stored items, and created conditions for mold. Then came the pest problem. All of that could have been prevented with a $150 seal replacement.
The Real Cost of Ignoring Worn Seals
Energy loss is invisible, which makes it dangerous. A compromised threshold seal can increase your heating costs by 10,15% if your garage is attached to your home. That's real money over a heating season.
Beyond energy, there's the domino effect: - Water damage to concrete, stored belongings, and vehicles - Pest entry.rodents and insects exploit gaps ruthlessly - Accelerated wear on your garage door opener and springs, which then cost hundreds to replace - Compromised insulation.if you've invested in an insulated door (as we discuss in our garage door insulation guide), failed seals undo that benefit entirely
I once serviced a home near Cambridge where gaps in the side seals had allowed water to pool behind the door frame. The metal was corroding. A $200 seal job six months earlier would have prevented $1,200 in frame replacement.
Types of Seals You Need to Know
Your garage door uses three main seal types, and each serves a purpose:
Bottom seals (thresholds): These run horizontally across the bottom of the door. They compress against the concrete floor and take the most abuse. They're your first defense against drafts and water.
Side seals: Vertical pieces that run along the left and right edges. They're softer than bottom seals and prevent drafts from the sides.
Top seals: Less common but important in some installations; they seal the gap between the door and the frame at the top.
When any of these fail, you lose the envelope of protection. Same-day replacement is often possible.it's not a time-consuming job for a trained technician.

How to Spot Failing Seals (Before Winter Hits)
Look for these red flags:
- Visible cracks, splits, or chunks missing from the rubber or foam - A gap you can see between the door and frame when closed - Daylight visible under the door on a sunny day - Drafts or cold air you can feel near the door - Water pooling or staining on the concrete inside the garage
The best time to inspect is late summer or early fall.before heating season strains your system. If you're not sure what you're looking at, request a free estimate. We'll assess your current seals and let you know the cost and timeline upfront.
Installation and Maintenance
Replacing weather stripping is straightforward. A technician removes the old seal (which usually just pulls or unscrews), cleans the surface, and installs the new one. Depending on which seals need work, the job takes 30,60 minutes.
To extend the life of your new seals: - Keep the garage clean and dry, Lubricate moving parts annually (per our seasonal maintenance tips) - Inspect seals twice a year, especially before winter, Avoid parking so close that you compress the side seals constantly
Quality matters. Cheap seals wear out in 2,3 years; better-grade materials last 5,7 years. Garage Door Company Somerville uses durable, weather-resistant seals designed for our climate.
Why Call a Professional
You can replace some seals yourself if you're handy, but improper installation leaves gaps. A loose bottom seal won't create a tight seal against your threshold, defeating the purpose. Our technicians know the exact pressure and alignment needed for your specific door model.
Plus, we often spot other issues during seal work.worn hinges, loose panels, or opener problems.that you might miss. Catching these early prevents costly repairs.
Your garage door works hard year-round. Proper weather stripping and seals are your best investment in its longevity and your home's comfort. Don't wait until January when it's freezing and you're desperate.

Do new seals help with energy costs? Absolutely. Proper seals reduce drafts and heat loss by 10,15% in attached garages. The savings pay for the replacement within a season or two.
What's the difference between rubber and foam seals? Rubber is more durable and handles temperature swings better; foam is softer and seals tighter initially but compresses faster. We recommend rubber for New England climates.
