Here's what most homeowners don't realize about weather stripping and seals: your garage door can lose more heat through a compromised bottom seal than through an uninsulated attic. In Westwood, where winters push temperatures well below freezing for months at a time, a failing threshold seal means your heating system works overtime. The good news? This is one of the cheapest, fastest fixes we handle. Most jobs take under an hour, and same-day service is almost always available.
Garage door seals live a harsh life. They compress thousands of times per year as your door cycles up and down. In New England's climate, freeze-thaw cycles crack rubber. Salt spray from winter roads hardens the material. UV exposure degrades vinyl. After 5 to 7 years, most bottom seals and side stripping lose their flexibility and stop creating an airtight closure. See our guide on commercial garage doors in westwood, ma: what business owners really need to know.
When the seal fails, cold air doesn't just sneak in. Moisture follows. Pests follow moisture. Your garage becomes a wind tunnel, and conditioned air bleeds from your home into an unheated space. If you've noticed your garage feeling drafty or spotted daylight under the door, the seal is almost certainly compromised.
The threshold is the most critical piece. This rubber or vinyl extrusion runs the full width of your door opening at ground level. It takes the most abuse from rolling tires, kicked debris, and repeated compression. A worn bottom seal won't stop a draft, and it won't keep water out during heavy rain either.

Not all weather stripping and seals are created equal. Westwood Garage Doors uses three main types depending on your door style and climate needs.
Bottom seals (threshold) come in two profiles: bulb and wiping. Bulb seals are softer and compress easily, ideal for doors that don't have perfect alignment. Wiping seals are firmer and create a tighter closure but require your door to sit perfectly level. For most residential doors in Westwood, we recommend bulb seals because they tolerate the minor settlement and shifting that happens in older homes.
Side seals run vertically along both sides of the door frame. These are often overlooked, but a gap here means draft directly into your garage. Side seals also prevent weather and pests from entering where the door panel meets the frame.
Top seals seal the header area above the door. These matter less for draft but are important if you park under the door opening or have a finished space above.
Our team can assess which seals have failed and which are still doing their job. Sometimes you only need the bottom seal replaced. Other times, a full seal replacement makes financial sense. We'll give you an honest estimate before we start work.

A bottom seal replacement typically runs between $150 and $350 installed, depending on door size and material. A full seal kit with top, sides, and bottom might be $300 to $600. These are real numbers, not bait-and-switch pricing. We've seen other shops charge $700 for a bottom seal alone, and we won't do that to you.
If you're considering a garage door tune-up in Westwood, seal replacement is a perfect add-on. A annual maintenance visit catches seal wear before it becomes a problem. Better yet, it prevents the hidden costs that sneak up when you ignore small issues.
The energy savings alone justify the cost. A properly sealed garage door reduces your heating load by 10 to 15 percent if your garage is attached to your home. Over a heating season in Massachusetts, that translates to real money back in your pocket.
If your seal is torn, cracked, or missing chunks, replacement is your only option. If it's just compressed but intact, sometimes we can adjust the door alignment to compress it better. We'll recommend replacement if the seal has less than a year of good performance left. No point in a band-aid fix.

How long do garage door seals last? Most bottom seals and weather stripping last 5 to 7 years in New England climates. Bulb seals often outlast wiping seals by a year or two. Regular maintenance and cleaning extend lifespan.
Can I replace weather stripping myself? Yes, for most homeowners. Bottom seals typically slide into a track and can be removed and reinstalled with basic tools. Side and top seals often require adjustment to door frame alignment. If you're unsure, call us for a same-day quote.
Will new seals really stop drafts completely? New seals eliminate 90 to 95 percent of draft through the door. A small amount of air movement is normal. If drafts persist after seal replacement, the door frame or panels may need adjustment.
What's the difference between a threshold and a bottom seal? A threshold is the metal or rubber piece mounted to the door frame at ground level. The bottom seal is the rubber extrusion that compresses against it. Both must be in good condition for an airtight closure.
Should I replace seals before winter? Absolutely. Fall is the ideal time. If you wait until January, we may be booked for same-day appointments. Call now to schedule your estimate before cold weather hits hard.
