Weather stripping and seals around your garage door work quietly to keep drafts out and your heating bill down. When they wear out, cold air sneaks in, your HVAC runs harder, and you start losing money every month. The good news: this is one of the most fixable problems in garage door maintenance, and catching it early saves hundreds in wasted energy.
McKenna winters are no joke. Our Pacific Northwest climate brings cold, wet weather that tests every seal on your home, especially around the garage door. A worn bottom seal or deteriorated threshold lets in more than just air. It invites moisture, pests, and that persistent draft you feel every time you walk past.
Your garage door is one of the largest moving parts of your home's envelope. If the seals fail, your heating system compensates by working overtime. Over a season, that adds up. Most homeowners don't realize how much they're spending until they finally replace worn seals and see their energy bills drop.
Seals typically last 3 to 5 years, depending on weather exposure and how often the door cycles. In McKenna, where we see significant rain and temperature swings, you may need replacements sooner. The bottom seal takes the most abuse because it contacts the ground and bears the weight of the door's movement.
Your garage door has seals in several places, and each serves a different purpose.
Bottom Seal (Threshold) This is the rubber or foam strip at the base of the door. It compresses when the door closes, creating a tight seal against the ground. A worn bottom seal is the most common culprit behind drafts and water intrusion.
Side Seals These run vertically along both sides of the door frame. They prevent air and moisture from slipping in at the edges. Unlike the bottom seal, side seals rarely wear as quickly because they don't bear the door's weight.
Top Seal Located above the door opening, the top seal blocks drafts from entering where the door meets the frame header. This seal often goes overlooked but is crucial in our rainy climate.
Threshold Some doors have a separate threshold piece at ground level that works with the bottom seal to create a weathertight fit. If either the seal or threshold warps, the whole system fails.

Look for these warning signs on your next inspection.
Light coming through gaps around the door frame means seals are shrinking or hardening. During the day, close your garage door and look for daylight around the edges. You shouldn't see any. Water pooling inside after rain indicates the bottom seal isn't doing its job. Drafts you can feel with your hand near the door are a clear signal that weatherproofing has failed.
Cracks, gaps, or visible deterioration in the rubber or foam are obvious red flags. If you press the seal with your finger and it doesn't spring back, the material has lost its compression and needs replacement. A professional inspection can catch damage that isn't visible to the naked eye.
If you haven't had a full garage door tune-up recently, seals are worth checking as part of that service. Our maintenance guide covers the complete picture and helps you avoid costly repairs down the road. Read about preventive maintenance in McKenna to see what else protects your investment.
Weather stripping replacement is straightforward and affordable compared to other garage door repairs. A bottom seal replacement typically runs between $150 and $300, depending on your door size and seal type. Side and top seals cost less because they're smaller and faster to install. Getting an accurate estimate before work begins helps you budget properly.
The process takes 30 to 60 minutes for a complete seal replacement. A technician removes the old seal material, cleans the track or frame to remove debris and old adhesive, then installs new seals designed for your door model. Quality matters here. We use seals rated for Pacific Northwest weather because standard materials don't hold up as well in our wet climate.
If you're curious about what a proper estimate should include, our guide to garage door repair quotes in McKenna walks through the details. Many homeowners are surprised at how affordable this preventive work is compared to emergency calls later.
DIY seal replacement is tempting, but precision matters. Improper installation leaves gaps that defeat the purpose. A professional ensures seals are aligned correctly, compressed to spec, and rated for our climate. Same-day service is often available, so you don't have to live with drafts while waiting for an appointment.

How often should I replace garage door seals? Most seals last 3 to 5 years in our Pacific Northwest climate. Inspect them annually, especially after winter. Replace immediately if you notice cracks, gaps, or loss of compression.
Can I replace seals myself? Technically yes, but professional installation ensures proper alignment and compression. Mistakes leave gaps that let drafts through. The labor cost is small compared to wasted energy over time.
What's the difference between a bottom seal and a threshold? A bottom seal is the compressible rubber or foam strip attached to the door. A threshold is a separate piece at ground level that the seal presses against. Both work together for a complete weathertight fit.
Do new seals really save money on heating? Yes. Worn seals force your HVAC to work harder in winter. Most homeowners see noticeable energy savings within the first billing cycle after replacement, especially in McKenna's cold season.
Is this an emergency repair? Not urgent, but don't delay. Worn seals let moisture in, which can damage the door frame and surrounding structure over time. Address them during your next maintenance window or call us for same-day service.
