Weather Stripping & Seals in North Georgetown: Why Your Garage Door Leaks (And How to Fix It)
2026-05-29 7 min read
Your garage door loses heat and lets rain in because the weather stripping has cracked or peeled away from the frame. A failing bottom seal or threshold gasket is one of the fastest ways to run up your heating bill and invite moisture damage into your garage. Let's cut through the confusion about weather stripping and seals so you know exactly what's failing and why it matters.
Why Weather Stripping Fails (It's Not Your Fault)
Weather stripping and seals aren't glamorous. They sit between your door and frame, taking a beating from temperature swings, UV rays, and constant friction. In North Georgetown, where winters drop below freezing and summer heat climbs into the 80s, that thermal stress adds up fast. See our guide on labor vs parts breakdown: making smart decisions.
The rubber and foam materials used in most seals have a realistic lifespan of 3 to 5 years if they're quality products. Cheaper seals fail in 18 months. I've seen homeowners pull away a bottom seal that had turned brittle and crumbly, leaving a half-inch gap straight to the outside. That's when they call in a panic because their garage is now 15 degrees colder than it should be.
The threshold (the seal running along the bottom of the door opening) takes the most punishment. Every time the door cycles, it compresses and relaxes. Rain pools against it. Snow piles on top. Eventually, the material loses its ability to compress, and you get a draft that you can feel with your hand.
Types of Seals and What They Actually Do
Not all weather stripping is the same. Understanding the difference helps you ask the right questions when you're getting an estimate.
Bottom Seal (Astragal): This is the rubber blade that hangs from the bottom edge of your door panel. It should touch the threshold with firm pressure. If it's worn down or missing, air and water flow right under the door. Replacing just the bottom seal typically costs between $150 and $300, depending on your door size.
Threshold Seal: This sits in the floor channel where the door closes. It creates the seal on the floor side. A damaged threshold often means water pooling in your garage after rain. It's a common culprit behind mold and concrete deterioration.
Side Seals and Frame Gaskets: These run along the left and right sides of the opening. They're less obvious when they fail, but a gap here lets in more draft than you'd expect. If you see daylight around the sides of a closed door, the side seals need attention.
Top Seal: Located above the door, this one protects against water running down the outside of the frame. It's easy to overlook until you notice water stains on the interior wall.
Proper weather stripping and seals work together as a system. One failing component forces the others to work harder, which speeds up their failure. That's why a professional inspection catches issues before they cascade.
How to Spot a Problem Before It Costs You Money
Walk around your garage door on a sunny day. Look for light gaps. On a windy day, hold your hand near the frame and feel for drafts. After rain, check the floor inside the garage for water marks or puddles near the door.
If your heating or cooling bill jumped 10 to 15 percent without explanation, a failing seal is a likely suspect. A 2-inch gap around a garage door opening can leak as much conditioned air as an open window.
Check the bottom seal visually. If it's cracked, compressed flat, or missing chunks, replacement is overdue. A seal that looks fine but feels hard and brittle to the touch is also done. Press it gently with your finger. It should compress and spring back.

Replacement Cost and What to Expect
A full weather stripping and seal replacement typically runs $300 to $600 for a single-car door, and $400 to $800 for a two-car door. The cost depends on seal type, material quality, and whether your frame needs repair before new seals can be installed.
If the frame is rotted or bent, you'll face additional costs. That's where a same-day estimate matters. A technician can assess the frame condition and give you a real number, not a guess. Don't assume you're just replacing rubber. Sometimes the underlying structure needs attention first.
North Georgetown Garage Doors offers competitive pricing and can often complete seal replacement the same day you call. No waiting weeks for parts to arrive. Emergency seal work during winter or spring storms is especially important because water damage spreads quickly in a garage.

Installation Matters More Than You Think
A $50 weather seal installed wrong is worse than no seal at all. Poor installation leaves gaps or creates misalignment that causes the door to bind. I've seen DIY attempts that actually trapped moisture between the seal and frame, accelerating rot.
Professional installation includes:
- Cleaning the frame groove thoroughly, Checking frame alignment before seal placement, Ensuring the bottom seal height matches your threshold, Testing the door cycle to confirm proper compression

Frequently Asked Questions
How long does weather stripping last before replacement? Quality weather stripping lasts 3 to 5 years in North Georgetown's climate. Cheaper materials fail sooner. Inspect annually and replace when rubber becomes hard, cracked, or compressed flat.
Can I replace weather stripping myself? You can replace bottom seals if you're handy, but frame seals and thresholds require precision. Improper installation creates gaps that defeat the purpose. Professional installation ensures proper compression and alignment.
What's the difference between a bottom seal and a threshold? The bottom seal hangs from your door and compresses downward. The threshold is the fixed piece in the floor. Both must work together. A damaged threshold can't be fixed by replacing the door seal alone.
Will new weather stripping reduce my energy bill? Yes. A properly sealed garage door can lower heating and cooling costs by 5 to 10 percent, depending on your current gaps. The payback happens within one to two heating seasons in most cases.
Do I need to replace all seals at once? Not necessarily, but inspecting all seals at the same time makes sense. If one has failed, others are likely aging too. A full replacement prevents multiple service calls.
