Weather Stripping & Seals in Eastham: Stop Drafts Before They Cost You
2026-04-30 7 min read
Here's what most homeowners don't realize about weather stripping and seals: a worn bottom seal lets in as much cold air as leaving a window cracked open all winter. On the Outer Cape, where wind and salt spray are constant threats, a failed threshold seal doesn't just waste energy.it lets moisture, pests, and debris straight into your garage. I've been servicing garage doors in Eastham for years, and I can tell you that fixing this problem early costs a fraction of what you'll pay in heating bills and rust damage later.
Why Your Garage Door Seals Matter in Eastham
Your garage is often the largest uninsulated space attached to your home. When the bottom seal deteriorates, air flows directly from outside into your garage and, eventually, into your house through interior walls. In Eastham's climate.especially during our long, windy winters.that draft adds up fast.
Weather stripping isn't just about comfort. A compromised seal lets in:
- Cold air that forces your HVAC system to work harder, Moisture that rusts springs, hinges, and the door frame, Salt-laden air that accelerates corrosion (we cover this in detail in our post on how salt air damages your door) - Insects, rodents, and debris
The bottom seal takes the most abuse. It flexes every time your door opens and closes, gets dragged across gravel and ice, and absorbs moisture. Most seals last 3,5 years before cracking or warping.
Signs Your Weather Stripping Needs Replacement
Check your seals right now. If any of these apply, you need service:
Visible cracks or gaps. Look at the rubber or vinyl along the bottom and sides. If it's split, hardened, or pulling away from the frame, it's not sealing.
Light showing under the door. Stand inside your garage at night with the door closed and lights off. Sunlight or streetlight coming under the door means the threshold seal is failing.
Drafts you can feel. Wave your hand along the bottom edge. You shouldn't feel air movement.
Ice buildup in winter. If moisture is freezing inside your garage, water's getting in through a bad seal.
Rust on hardware. Premature rust on springs, brackets, or the frame suggests moisture intrusion.often from failed seals.
Types of Weather Stripping & Seals We Install
Not all seals are created equal. Here at Eastham Garage Doors, we stock and install the right material for your door and climate.
Bottom seals (threshold seals). These are the most critical. We install heavy-duty rubber or vinyl seals that withstand repeated flexing and Cape weather. A good bottom seal costs between $150,$300 installed, depending on door width.
Side seals. These run along the vertical tracks and prevent side drafts. They're often overlooked but essential in exposed locations.
Top seals. Less common, but if your garage is poorly insulated, a top seal reduces heat loss.
Weatherstripping tape. For minor gaps around the frame, adhesive-backed foam tape works as a temporary fix, though it won't last as long as rubber seals.

DIY vs. Professional Installation
You can replace some weatherstripping yourself.foam tape, for instance.but the bottom seal requires removing the door track and often realigning the door. Get it wrong and your door won't close properly or will bind.
Our estimate is free. We'll inspect your existing seals, measure your door, and tell you exactly what's needed. Most jobs take under an hour. We handle same-day appointments whenever possible because I know a draft in April means higher bills in May.
If your garage door has other issues.like worn springs or damaged panels.we'll spot them during the seal inspection. You might also want to read our guide to preparing your garage door for summer to address any other maintenance before the season shifts.
Cost and What to Expect
A full bottom seal replacement with labor typically runs $200,$400 in Eastham. Side seals add another $100,$200 if needed. Yes, it's an upfront cost, but the energy savings and rust prevention pay for themselves in 1,2 winters.
We don't upsell. If your seals still have life in them, we'll tell you. But if they're cracked or pulling away, replacing them now prevents expensive frame damage and keeps your heating bills honest.
Take Action Before Summer Heat Arrives
Spring is the perfect time to seal your garage. Temperatures are mild, you're not running your heating, and you'll have the whole season to evaluate the difference before next winter. A fresh seal also keeps your garage cooler and drier through summer, reducing AC load and protecting stored items from humidity.

Your garage door's seals aren't glamorous, but they're one of the smartest maintenance investments you can make.
Frequently Asked Questions
How long do weather stripping and seals last? Rubber and vinyl seals typically last 3,5 years in Eastham's climate. Exposure to salt air, UV, and repeated flexing shortens their life. We recommend inspection annually and replacement when you see cracks or gaps.
Can I just use weatherstripping tape instead of replacing the bottom seal? Tape works for small gaps, but it won't last more than a season or two. A proper bottom seal is worth the investment if you want reliable, long-term protection against drafts and moisture.
What's the difference between rubber and vinyl seals? Rubber is more durable and handles extreme temperatures better; vinyl is less expensive but degrades faster in UV light. For Eastham's coastal environment, rubber is the better choice despite slightly higher cost.
Will new seals help my heating bills? Yes, significantly. A compromised seal can increase heating costs by 10,15% in winter. A fresh seal reduces drafts and lets your HVAC system run more efficiently, paying for itself quickly.
Do you offer same-day service for seal replacement? We do when scheduling allows. Call (508) 388-5346 to check availability. Many routine seal jobs can be completed the same day or within 24 hours.
