Most homeowners in Westmoreland don't realize their garage door is bleeding heat and letting cold air pour in. Weather stripping and seals fail silently. You notice higher utility bills, then feel the draft months later. The good news: replacing worn seals is straightforward, affordable, and worth doing right before winter arrives.
A garage door isn't just an entry point for cars. It's often the largest uninsulated opening in your home. When weather stripping deteriorates, gaps form around the edges where the door meets the frame. Cold air rushes in during winter. Conditioned air escapes in summer. Your HVAC system works harder. Your utility bill climbs. See our guide on garage door openers in westmoreland: which type saves you money?.
The bottom seal takes the most punishment. It compresses under the door's weight, flexes with temperature swings, and gets scraped by ice, snow, and road salt. In Westmoreland's climate, a bottom seal typically lasts 4 to 6 years before cracking or hardening. Top and side seals often outlast the bottom, but they fail too.
Not all weather stripping performs equally. Rubber seals are durable and affordable, costing around $50 to $150 for a full set depending on door size. Vinyl seals offer better flexibility in cold climates and resist cracking longer. Foam seals are cheaper but deteriorate fastest in New England weather.

The threshold seal at the bottom deserves special attention. It compresses under constant load and endures direct contact with the ground. Look for visible cracks, hardening, or gaps wider than 1/4 inch. If your garage feels drafty or you see daylight under the door, the threshold is likely the culprit.
Side and top seals wear more slowly but still need inspection annually. Check them before winter, when sealing performance matters most. Many homeowners skip this step, only to discover drafts when temperatures drop below freezing.
If you haven't had your door inspected recently, Westmoreland Garage Doors can evaluate your seals and identify problem areas in one visit. We'll provide a clear cost estimate and explain exactly what needs replacing.

Pay attention to warning signs before they become expensive problems. Drafts under the door, visible gaps, or rubber that looks cracked or hardened are clear indicators. You might also notice increased heating costs, especially if your garage is insulated or connected to your home.
Frost buildup along the bottom edge in winter suggests the seal isn't sealing properly. Dust and debris collecting inside the garage door frame point to gaps that let outdoor air flow freely. These aren't just comfort issues. They add up to real money lost on heating.

Replacing weather stripping yourself is possible if you're handy, but precision matters. Seals must compress evenly, or they'll fail unevenly. Poor installation creates new drafts in spots you didn't intend. Professional installation ensures the threshold and all side seals compress uniformly and last their full lifespan.
Labor typically adds $100 to $300 depending on door size and seal condition. Westmoreland Garage Doors offers same-day estimates so you know the cost upfront. No surprises. No hidden fees.
If your door has other issues like misaligned tracks or worn springs, seals won't solve the problem. Check our troubleshooting guide if your door isn't closing smoothly. Sometimes multiple repairs are needed for a door to seal and operate correctly.
A properly sealed garage door reduces heating loss by 10 to 15 percent if your garage is insulated. Even uninsulated garages benefit from stopping drafts near the house. Over a heating season, that translates to $150 to $400 in savings for most Westmoreland homes, depending on energy costs and insulation levels.
Seals also protect your door's mechanisms. Without proper seals, water and salt spray corrode springs, hinges, and hardware. Replacing seals now prevents expensive repairs later. It's preventive maintenance that pays for itself.

How long do garage door seals last? Bottom seals typically last 4 to 6 years in New England climates. Side and top seals often last 7 to 10 years. Lifespan depends on weather exposure, UV damage, and how often the door cycles.
Can I replace seals myself? Yes, if you're comfortable with basic tools. However, professional installation ensures even compression and proper seating. Improper installation can create new drafts and void warranties.
What's the difference between a bottom seal and a threshold? The bottom seal is the rubber or vinyl strip attached to the door's bottom edge. The threshold is the track or channel at the bottom of the frame that the seal compresses into. Both must be in good condition for effective sealing.
