A customer called last Tuesday complaining her heating bill jumped $40 a month. Her garage door had a worn bottom seal letting cold air pour in. The fix? New weather stripping and seals.under $300 total. No replacement door needed. This is the most common (and most preventable) energy drain we see in Onalaska homes, and it's cheaper to address now than to ignore it.
Your garage door isn't just about convenience.it's a thermal barrier. A damaged bottom seal, cracked threshold, or worn side seals let outside air leak directly into your garage and conditioned spaces beyond. In Onalaska's climate, where winters dip below freezing and moisture is constant, this draft compounds fast.
Most homeowners don't realize seals wear out every 3,5 years depending on weather exposure and how often the door cycles. Unlike springs (which last 7,9 years), seals take a beating from temperature swings, UV rays, and friction. The good news: replacement is straightforward and affordable if you catch it early.
Look for these warning flags:
- Visible cracks or peeling along the bottom seal or side jambs - Daylight visible around the door frame when closed - Cold drafts in your garage or adjacent rooms - Water pooling inside after rain (a failed threshold seal) - Higher heating/cooling costs with no other explanation
If you've already had an energy audit or noticed insulation gaps, worn seals often compound the problem. Don't assume you need a new door.seal replacement is the first move.
Bottom Seals (Sweeps) The most critical piece. This vinyl or rubber strip hangs from the bottom of your door and creates a barrier against drafts and pests. Replacement cost: $80,$150 installed.
Side Seals (Jamb Seals) Run along the left and right edges where the door meets the frame. They prevent lateral drafts and water intrusion. Often overlooked but just as important.
Threshold Seals The horizontal strip at the floor level. Worn thresholds let water pool inside and cold air flow under the door. Replacement: $120,$200.
Top Seals Less common but vital if your door is older. Protects the top of the frame from rain and wind.

DIY Option If you're handy, replacement seals are available at hardware stores. Cost: $40,$100 in materials. Expect 1,2 hours of work. Measure twice, watch a tutorial, and go slow.
Professional Install Garage Door Onalaska can handle this in under an hour. We ensure seals are aligned perfectly.misalignment kills effectiveness. Professional cost: $250,$400 total (materials + labor), but you skip mistakes and get a warranty.
For most homeowners, professional installation pays for itself in one heating season, especially if you're borderline on DIY confidence. A crooked seal won't seal properly, leaving you paying the draft cost anyway.
Think seals are expensive? Consider the alternative: - Wasted energy: $40,$80/month in winter months (that's $200,$400 per season) - Water damage repairs: $500,$2,000+ if moisture gets into framing, HVAC strain: shorter equipment lifespan, earlier replacement
A $300 seal job pays back in 4,6 months. That's budget-conscious math.

How long do garage door seals last? Bottom seals and thresholds typically last 3,5 years in Onalaska's climate. Side and top seals may stretch to 5,7 years. UV exposure, temperature swings, and daily cycling speed wear. Inspect annually.
Can I replace just the bottom seal, or do I need all seals replaced? You can replace seals individually. Start with the bottom seal if that's where you see damage. However, a full inspection often reveals multiple problem areas. We recommend addressing all worn seals at once to maximize energy savings.
Will new seals fix my water damage? New seals prevent *future* water entry, but existing damage needs separate repair. A failed threshold seal lets water pool; replacing it stops the leak. Structural damage requires additional work.we'll assess during your estimate.
Do weather stripping seals affect garage door balance? No. Seals are passive barriers and don't interact with the door's balance or spring tension. A balanced door and good seals are both essential, but they're independent systems.
What's the best time to replace seals in Onalaska? Fall is ideal.before winter cold and rain arrive. Spring is second-best, after winter exposure. Avoid summer if possible; heat makes vinyl seals harder to install. We offer same-day service year-round, so don't wait if you spot damage now.
