Weather Stripping & Seals in Union: Why Your Garage Door Loses Heat Fast
2026-05-18 7 min read
If your garage feels drafty even with the door closed, worn weather stripping and seals are likely the culprit. A damaged bottom seal or threshold lets conditioned air slip away, raising your heating and cooling costs. We'll show you how to identify the problem and what a professional repair actually costs in Union.
What Weather Stripping Does (And Why It Fails)
Weather stripping is the rubber or foam gasket that runs along the edges of your garage door. The bottom seal does the heaviest lifting, pressing against the concrete threshold when the door closes. Over time, UV exposure, freeze-thaw cycles, and regular wear cause these materials to crack, harden, or separate from the frame. See our guide on belt replacement: a complete guide for homeowners.
In Union, our winters bring moisture and temperature swings that accelerate deterioration. A seal that looked fine in September might split by January. When it fails, you lose the airtight barrier that keeps out cold air, rain, and pests. Your furnace works harder. Your energy bill climbs. Simple math.
Signs Your Seals Need Replacement
Look for these red flags when you inspect your garage door:. Read about garage door insulation in union: why it matters & what it costs.
Visible cracks, tears, or missing chunks in the rubber. If you see daylight under the door when it's closed, the bottom seal has failed. Cold drafts near the door frame, especially around the sides and top. Water pooling inside after rain indicates a failed threshold seal. Pests or insects entering the garage suggests gaps large enough for unwanted visitors.
The bottom seal takes the most abuse. It gets compressed thousands of times a year and sits in standing water if your concrete has any slope. Most bottom seals last 5 to 7 years before needing replacement. Don't wait until water damage spreads to your flooring.

Professional Repair vs. DIY Attempts
You can buy replacement seals online for $30 to $80, and some homeowners successfully install them. But there's a catch: you need the exact profile for your door model, proper tools to remove the old gasket, and enough strength to seat the new one correctly. Many DIY installs leave gaps or wrinkles that defeat the purpose.
A professional inspection also catches problems beyond just the seal. We check whether the door is closing evenly, if the frame is bent, or if hinges are misaligned. These issues can cause premature seal wear and make a new seal fail faster. Our team at Garage Door Union has installed hundreds of seals in Union and the surrounding region. We know the local weather patterns and which materials hold up best here.

What You'll Pay for Weather Stripping & Seals
Costs break down like this. A bottom seal replacement runs $150 to $350 installed, depending on your door size and condition. Side seals and top gaskets add $100 to $150 each if needed. An estimate is always free. We measure your door, assess the condition of the frame, and tell you exactly what's required before you commit to anything.
Many homeowners are surprised by how affordable this fix is compared to energy waste over a year. If your draft costs you an extra $20 per month in heating, a $250 seal pays for itself in about a year. After that, it's pure savings.

Common Questions About Seals and Drafts
A damaged seal won't affect your door's operation unless it's so deteriorated that it jams the rollers. However, a door that's dragging or not closing smoothly can damage seals faster. If you notice both problems, have the door mechanism inspected first. Our [garage door repair guide] covers what to do when alignment issues emerge. (/blog/garage-door-repair-union-wa-20260513)

Frequently Asked Questions
How long does a weather seal last? Most bottom seals and gaskets last 5 to 7 years in our climate. UV exposure, freeze-thaw cycles, and daily compression accelerate wear. Inspect annually and replace at first sign of cracking.
Can I replace the seal myself? Yes, if you have the right profile and tools. Many homeowners succeed with online kits. However, professional installation ensures proper fit and checks for frame damage that could cause premature failure.
Will a new seal stop all drafts? A new seal eliminates gaps under and around the door. If you still feel cold air, the door may not be closing evenly, or the frame could be warped. We inspect both during any seal replacement.
How much does a weather seal cost installed? Bottom seals typically run $150 to $350 installed. Side and top seals add $100 to $150 each. We provide free estimates with no obligation.
Does weather stripping affect my door's operation? No. A properly installed seal shouldn't change how your door moves. If it does, the frame alignment is likely off and needs adjustment before sealing.
