In our years serving Burlington, we've seen this problem again and again: homeowners lose hundreds of dollars to energy waste because their garage door's weather stripping and seals have dried out or cracked. A worn bottom seal lets cold air pour into your home during winter, and heat escapes in summer. The good news? This is one of the cheapest fixes we perform, and catching it early saves you far more than the replacement cost.
Rubber seals don't last forever. Sun exposure, freeze-thaw cycles, and constant opening and closing all degrade the material. In the Pacific Northwest, our climate is especially tough on seals. Rain, moisture, and temperature swings mean most weather stripping lasts 5 to 7 years before it hardens, cracks, or separates from the frame. See our guide on garage door insulation in burlington: why your door loses heat and what to do.
The bottom seal takes the most punishment. It sits closest to the ground, absorbing moisture and enduring impacts from debris and lawn equipment. When it fails, you'll notice drafts under your garage door, dust accumulation inside, and higher heating bills. Some homeowners ignore this thinking it's a minor cosmetic issue. That's a mistake. A deteriorated threshold seal can let rodents inside and allow moisture to damage your garage floor and foundation over time.
Let's talk numbers. A full weather stripping and seal replacement in Burlington typically costs between $200 and $400, depending on your door size and seal type. Compare that to the energy loss from a failing seal: studies show a single unsealed gap can add $15 to $30 per month to your heating bill in winter. Over a year, that's $180 to $360 wasted. Replace the seal once, and you've paid for itself in a single season. Read about garage door won.

Most garage doors use three types of seals: the bottom seal, side seals (jamb seals), and top seals (header seals). Each serves a specific purpose.
The bottom seal is the workhorse. It compresses against the floor when your door closes, creating an airtight barrier. When this fails, drafts pour in immediately.
Side seals run along the vertical jambs on both sides of the opening. These prevent air from sneaking around the edges. Worn side seals let noise in and conditioned air out.
Top seals sit above the door frame. They block weather from entering the gap between your garage ceiling and the door opening. Though less visible, a failed top seal causes noticeable drafts and pest entry.
If your door won't close properly or you suspect seal damage, don't wait. A failed seal can lead to other problems if moisture gets inside the door mechanism. Our garage door maintenance schedule recommends inspecting seals twice yearly, especially before winter.
Sometimes you don't need a full replacement. If your seals are just dirty or slightly misaligned, we can clean and re-seat them for under $100. This buys you another season or two.
But if seals are cracked, hardened, or permanently compressed, replacement is the only real fix. Trying to patch a failing seal with caulk or weatherstripping tape is a temporary band-aid. You'll be back to the same problem in weeks.

Once you replace your seals, a little maintenance extends their life. Keep your garage door track clean and lubricated. Dirt buildup forces seals to work harder and wear faster. In winter, clear ice and snow away from the bottom of your door. Ice buildup pushes against seals and causes premature failure.
If you're in the Shelburne area or anywhere near Burlington, we serve the whole region. For homes with chronic draft problems, consider whether your door needs fuller insulation upgrades alongside new seals. Our team can assess both at once and prioritize the most cost-effective solution for you.
How often should I replace garage door weather stripping? Most seals last 5 to 7 years in our climate. Inspect them twice yearly. If they're cracked, hardened, or leaving visible gaps, replace them sooner. Regular cleaning extends their life.
Can I replace seals myself? Yes, if you're handy. Bottom seals are easiest. Side and top seals require more precision. If your door is under warranty or has a complex track system, let professionals handle it to avoid voiding coverage.
What's the difference between a bottom seal and a threshold seal? They're often used interchangeably. Both refer to the rubber or vinyl piece at the base of your door. Some thresholds include a rigid base for extra protection against impacts.
Will new seals help my energy bills? Absolutely. A single failed seal can add $200+ annually to heating costs. New seals pay for themselves in one winter in most homes.
How do I know if seals are failing? Look for visible cracks, hardening, or separation from the frame. You'll also notice drafts, dust inside the garage, or higher utility bills. Call us for a free inspection if you're unsure.
