Weather Stripping & Seals in Lewisville: Stop Drafts and Save on Energy
2026-07-24 7 min read
A customer called last Tuesday saying her heating bill had jumped forty dollars a month. We inspected her garage door and found the culprit: a worn bottom seal letting cold air pour underneath. She'd been losing conditioned air for months without realizing it. A simple weather stripping replacement took ninety minutes and cost less than two weeks of that inflated bill. That's the power of catching seal problems early.
Your garage door's weather stripping and seals do more heavy lifting than most homeowners realize. They form a barrier against drafts, moisture, pests, and temperature swings. When they wear out, your HVAC system works overtime to compensate. The good news: fixing this won't drain your wallet, and the energy savings pay back the investment quickly.
What Weather Stripping Does (And Why It Matters)
Weather stripping is the rubber or foam material that runs along the perimeter of your garage door. The bottom seal is the most critical piece, sitting directly against the threshold where your door meets the concrete. Together, they block drafts that let heat escape in winter and cool air leak out in summer.
Without proper seals, your garage becomes a conduit for outside temperatures. If your garage is attached to your home, that draft pulls energy from your living spaces too. Over a heating or cooling season, bad seals can add $15 to $40 monthly to utility costs. That's $180 to $480 a year in wasted money.
Lewisville's climate shifts between hot summers and cold winters, making robust seals essential year-round. Check your door's condition now before the next season hits hard.
Signs Your Seals Need Replacement
Look for these red flags: visible cracks or chunks missing from the rubber, gaps you can see daylight through, or a musty smell coming from the garage. If you feel a draft under the door on a calm day, the bottom seal is likely shot. Some seals compress over time and no longer make contact with the threshold.
Rodents and insects finding their way in is another telltale sign. A gap that lets air through also lets critters through. If you've spotted spiders, ants, or worse in your garage, worn seals could be the entry point.
Most weather stripping lasts 5 to 7 years depending on exposure and climate. If your door is older than that, seals are probably due for replacement. Our team at Garage Door Lewisville can inspect your door and give you an honest estimate without pressure.

Cost of Weather Stripping & Seals (What You'll Actually Spend)
Bottom seal replacement typically runs $100 to $250, depending on your door size and material. Side seals and top seals cost $50 to $150 each. A complete weather stripping package for all four sides might be $300 to $500.
Compare that to your monthly energy overages. If you're losing $30 a month to drafts, you'll recover the cost in 10 to 17 months. After that, every month is savings. Plus, you'll have a more comfortable garage and protected items stored inside.
Don't skip this repair thinking it's too minor. Small leaks compound fast. Some homeowners delay and end up spending more on energy bills than the actual repair would have cost. Schedule a free quote to see what your specific situation needs.
DIY vs. Professional Replacement
You can buy weatherstripping kits online for $30 to $80 and install them yourself if you're handy. The process involves removing the old material, cleaning the tracks, and adhering new strips. It's straightforward but requires precision to seal properly.
The trade-off: a professional installation guarantees proper alignment and material selection for your door type. If the threshold itself is damaged or the door frame isn't level, a DIY fix won't solve the underlying problem. A technician spots these issues during inspection.
For most homeowners, professional installation is worth the extra cost. You avoid mistakes that waste money on materials, and you get a warranty on workmanship. Learn more about our maintenance services to see what's included.
Energy Savings You'll Actually See
After weather stripping replacement, most homeowners report 10 to 15 percent lower HVAC costs during the relevant season. That's $10 to $25 monthly in a typical Lewisville home. Over five years, that's $600 to $1,500 in pure savings.
The benefit extends beyond money. Better seals mean fewer temperature swings in your garage, which protects stored items, batteries, and tools. Your car's engine won't be as cold on winter mornings. Humidity stays more stable, reducing mold risk.
Don't overlook this simple fix. Weather stripping is one of the highest-return maintenance items you can do on a garage door. Call us at (336) 600-4636 or get a same-day estimate to move forward.
Frequently Asked Questions
How long does weather stripping last? Most seals last 5 to 7 years in North Carolina's climate. Exposure to intense sun, freeze-thaw cycles, and friction wears them faster. Check annually and replace when you see visible cracks or gaps.
Can I replace just the bottom seal, or do all sides need work? You can replace individual seals as needed. However, if other sides are aging too, replacing everything at once saves labor costs and ensures uniform protection against drafts and moisture.
Will new seals reduce noise from my garage door? Yes, slightly. Worn seals let the door vibrate against the frame more. New, snug seals dampen some operational noise. For serious noise issues, check our guide on noisy garage doors for other causes.
How much energy will I save with new weather stripping? Most homeowners see 10 to 15 percent lower HVAC costs during heating or cooling seasons. Exact savings depend on your door's current condition, insulation, and local energy rates.
Should I replace weather stripping in summer or winter? Either works fine. Schedule during off-peak seasons if possible, so the adhesive cures fully. Spring and fall are ideal in Lewisville since temperatures are moderate.
