Weather Stripping & Seals in Westport, CT: Stop Drafts Before Winter
2026-07-02 7 min read
A customer called last Tuesday with ice forming inside her garage and a $200 heating bill spike. The culprit? A worn bottom seal letting cold air pour underneath. Weather stripping and seals in Westport are your first defense against drafts, energy loss, and weather damage. Replace them now, and you'll sleep warmer this winter without the shock on your utility bill.
Why Your Garage Door Seals Fail
Westport winters are brutal. Snow, freeze-thaw cycles, and salt spray all attack rubber seals relentlessly. Most homeowners don't realize how quickly these wear out. A typical bottom seal lasts 5 to 7 years before it cracks, shrinks, or hardens. Side seals and threshold strips deteriorate even faster in areas near the coast, where salt and moisture accelerate breakdown.
I've pulled up to houses in Darien and Weston with seals so cracked you could see daylight underneath. By then, the damage spreads. Cold air drafts into the garage, your HVAC works overtime, and moisture creeps into the weatherstripping gaps, rotting wood and corroding hardware.
What Happens When Seals Go Bad
A loose or missing bottom seal creates more than just a draft. It's an open invitation for pests, water intrusion, and loss of conditioned air. If your garage is finished or insulated, energy bills climb 10 to 15 percent with bad seals. Unfinished garages lose heat to the exterior, but the cold still radiates inward and affects attached living spaces.
I also see damage to the garage door itself. Water pools under the door frame, ice buildup warps panels, and salt corrodes the bottom section. Many homeowners think they need a full door replacement when really they just need a new threshold and quality weather stripping installed properly.
The good news? This is one of the most cost-effective repairs you can make. A threshold and seal replacement typically runs $150 to $400 depending on door width and material choice. Compare that to a new door at $1,200 and up, and you'll see why preventive maintenance pays off.

Types of Seals and When to Replace Them
Not all seals are the same. The bottom seal is the workhorse, taking the most abuse. It compresses against the floor and wears fastest. Side seals run vertically and protect against wind-driven rain. The threshold sits under the bottom seal and provides a structural stop point.
I recommend replacing all three together. Mixing old and new doesn't work well because the worn seals won't compress evenly, leaving gaps. We use EPDM rubber or vinyl, both lasting longer than the cheap foam strips you see at big box stores.
If you're still running the original seals from when your door was installed, schedule an inspection now. Many homes built in the 1990s and early 2000s have seals that are long overdue for replacement.

How to Spot a Bad Seal
Look underneath your door on a sunny day. If you see a line of light, that's a gap. Shine a flashlight into the seal itself. Cracking, brittleness, or hardness means replacement time is here. In winter, ice formation under the door is a dead giveaway that the bottom seal isn't sealing.
Drafts are obvious too. Stand near your closed door on a cold day and feel for air movement. Cold spots on the garage floor near the door indicate seal failure. Water stains on the concrete directly under the door frame also suggest moisture is getting past your seals.

Frequently Asked Questions
How often should I replace garage door weather stripping? Every 5 to 7 years for bottom seals in Westport's climate. Side seals and thresholds may last longer if protected. Salt spray near coastal areas accelerates wear, so check annually.
Can I replace seals myself? Yes, for simple side seal replacement on some doors. Bottom seal and threshold work require proper tools and alignment skills. Improper installation creates gaps that defeat the purpose.
What's the cost difference between foam and rubber seals? Foam seals cost $50 to $100 installed but last 2 to 3 years. Quality rubber runs $150 to $300 installed and lasts 7 to 10 years. The rubber pays for itself in energy savings and durability.
Will new seals reduce my heating bill? Yes, noticeably if your seals were badly worn. Expect 10 to 15 percent reduction in garage heating costs once proper seals are installed. The payback period is typically 1 to 2 years.
What's the difference between a threshold and a bottom seal? The threshold is the metal or rubber base that sits on the concrete. The bottom seal (or weatherstripping) compresses against the floor on top of or attached to the threshold. Both work together to create a tight seal.
