In our years serving Antrim, we've seen this problem again and again: homeowners ignore small gaps around their garage doors, then watch heating and cooling costs climb through the winter and summer. The good news? Worn weather stripping and seals are among the cheapest fixes we handle, and they pay for themselves fast. Here's what you need to know to stop drafts and keep your wallet intact.
Your garage door's weather stripping and bottom seal take a beating. They flex thousands of times a year, get compressed by thermal changes, and eventually crack or harden. In Antrim's climate.where we see real cold snaps and humidity swings.these components wear out faster than most homeowners expect.
The typical lifespan is 3,5 years before seals lose their compression. Once they do, you're losing conditioned air year-round. That draft you feel? It's also letting in dust, pests, and moisture. A single worn threshold seal can cost you $15,$30 per month in wasted heating or cooling.
Check your seals right now. Press your hand against the bottom of your garage door on a windy day. Feel air movement? That's your cue.
Not all seals are equal. Understanding your options helps you avoid overpaying for features you don't need.
Bottom Seals (Threshold Seals) The horizontal strip at the garage door's base. This takes the most abuse because it compresses every time the door closes. Rubber and vinyl versions cost $20,$50 to replace, though labor adds another $75,$150.
Side Seals (Jamb Seals) Run vertically along both sides of the opening. These often last longer than bottom seals but still need inspection every couple of years. Expect $30,$80 for materials.
Top Seals (Header Seals) Sit above the door opening. Less prone to wear, but a damaged top seal can let in significant water and debris during heavy rain.
Reinforced vs. Standard Reinforced seals cost 20,30% more but last 6,12 months longer in harsh New England weather. For Antrim homeowners, the extra upfront cost often pays off.

Don't wait for a heating bill spike to act. Watch for these red flags:
- Visible cracks or gaps in the rubber or vinyl - Hard, brittle strips that don't compress when you push them - Daylight visible around the door frame on a sunny day - Water pooling inside the garage after rain - Drafts or whistling sounds during wind - Pest droppings or evidence of rodents near the door
Even one of these signs means it's time for a professional estimate.
You can buy weather stripping kits for $15,$40 online. Installing them yourself takes 1,2 hours and requires a screwdriver, caulk gun, and patience. If you're handy and your seals are simply worn (not damaged), DIY might work.
But here's the catch: improper installation leaves gaps. Gaps defeat the purpose. A professional installation from Garage Door Antrim runs $150,$300 total and includes:
- Inspection of rollers and springs (catching bigger problems early) - Proper alignment and compression, Warranty coverage if seals fail prematurely, Same-day availability in most cases
If your door is older or you've never had seals replaced, professional work is worth every penny. It also ensures you're not missing spring wear or roller damage that compounds draft problems.
Antrim winters stress every part of your garage door. Cold makes rubber brittle. Ice and salt accelerate seal degradation. If you wait until January to address drafts, you'll pay premium pricing and face longer wait times.
Schedule seal replacement in fall. Your heating bill will thank you.
