Weather Stripping & Seals in Millis, MA: Stop Drafts Before Winter
2026-08-25 7 min read
Yes, you need to replace your weather stripping and seals. In our years serving Millis, we've seen this problem again and again: homeowners ignore worn seals, energy bills climb, and cold air pours into the garage every winter. A degraded bottom seal or threshold costs you real money in heating. The good news? This is one of the cheapest fixes we offer.
Why Your Garage Door Seals Matter More Than You Think
Your garage door is one of the largest moving parts of your home's envelope. When the bottom seal wears out, warm air escapes, cold air drafts in, and your heating system works overtime. In Massachusetts winters, that's not a minor inconvenience. It's a direct hit to your utility bill.
Seals wear faster than you'd expect. Weather stripping deteriorates from UV exposure, temperature swings, and constant friction as the door opens and closes. Over three to five years, rubber becomes brittle. Vinyl cracks. The threshold loses its seal against the concrete floor. By the time you notice a draft, the damage is already done.
The threshold is often the worst offender. This rubber or vinyl strip sits at the bottom of the door and makes contact with the ground every single cycle. It bears the weight of the door, the impact of closing, and constant exposure to moisture. Once it starts failing, water seeps into your garage, pests find entry points, and thermal efficiency plummets.
Types of Seals and What They Cost
There are three main seal components on a typical garage door. Understanding each one helps you avoid overspending on repairs you don't need.
Bottom seal (or bottom weather strip): This runs horizontally across the bottom of the door panel. Replacement cost is typically $150 to $300 installed, depending on door width and material quality. It's the most common failure point.
Side seals: These vertical strips run along the left and right edges. They prevent drafts and keep debris out. Replacing both sides costs $100 to $200.
Threshold: The rigid or semi-rigid strip on the ground. This one's trickier because installation requires precision. Expect $200 to $400 for removal, installation, and adjustment.
Many homeowners ask if they can just caulk around the door instead. Don't. Caulk fails faster, doesn't flex with temperature changes, and won't solve draft problems. Quality seals do the job right the first time.

How to Know When Seals Need Replacing
Look for these warning signs before winter arrives. If you see daylight under the door when it's closed, seals are shot. If you feel air movement around the door frame on a calm day, drafts are getting in. Moisture or water pooling inside the garage after rain signals a failed threshold or bottom seal.
You can also do a simple visual inspection. Open the door fully and examine the rubber or vinyl. Cracks, hardening, or visible deterioration means replacement time. If seals look compressed and don't spring back when you press them, they've lost their seal integrity.
One practical test: on a cold night, turn off your garage lights and look for light leaks around the door edges. Any visible gaps mean air is moving through. That's money heating the outside.

Maintenance Keeps Seals Alive Longer
You can extend seal life with basic care. Keep the door clean and dry. Remove debris from the bottom seal track. In winter, clear snow and ice away from the door base so seals don't freeze in a compressed state. Lubricate seals lightly with silicone spray (not oil) to keep rubber flexible.
If your garage door hasn't had a tune-up recently, seals might not be your only issue. Read our guide to garage door lubrication and inspection to understand what else could be costing you money.

Frequently Asked Questions
How long do garage door seals last? Quality weather stripping typically lasts 3 to 5 years in Massachusetts. Thresholds may last 4 to 6 years. Lifespan depends on climate exposure, door usage frequency, and maintenance.
Can I replace seals myself? Bottom seals are DIY-friendly if you're handy. Thresholds require more precision and tools. Side seals vary by door type. When in doubt, professional installation ensures proper fit and avoids costly mistakes.
Does weather stripping help in summer too? Yes. Seals prevent cool air from escaping when air conditioning runs. They also keep out dust, pollen, and pests year-round. You benefit every season.
Are expensive seals worth the premium cost? Mid-range seals (rubber or vinyl blends) offer the best value. Premium options last longer but cost 20 to 30 percent more. Standard seals are fine for most Millis homeowners.
What if my door still drafts after new seals? Sometimes the door frame or panel itself has gaps. Our team can identify hidden draft sources and recommend the most affordable fix during your inspection.
