In our 15 years serving Manor, we've seen this problem again and again: homeowners wait too long to replace worn weather stripping and seals, then wonder why their energy bills spike and their garage stays drafty year-round. The truth is simple. Your garage door's bottom seal and threshold wear out on a predictable timeline, and catching it early saves money, comfort, and headache.
Most quality weather stripping and seals last between 4 and 7 years in Texas, depending on sun exposure, humidity, and how often you open and close the door. The bottom seal takes the most punishment because it contacts the concrete threshold every single time the door opens. UV rays and temperature swings in Manor can accelerate degradation, especially during our hot summers and occasional cold snaps.
If your door was installed between 2019 and 2021, now is the time to inspect it closely. Seals don't fail all at once. They crack, harden, and lose compression gradually. By the time you notice a draft or see daylight under the door, the seal has already stopped working effectively.
Visible cracks or chunks missing. Walk outside and look at the bottom seal and side jamb seals. If you see splits, hardening, or rubber missing entirely, replacement is overdue. Don't wait for the next season.
Drafts you can feel. Stand inside your garage on a windy day. If you feel air coming under the door or along the sides, the seal is compromised. This draft also means insects and dust are getting in.
Daylight visible under the door. This is the clearest sign. Healthy seals compress and block light. If you see gaps, the seal has lost its compression and flexibility.
Higher energy bills. Worn seals force your HVAC system to work harder, especially if your garage is heated or cooled. A few months of higher bills often equals the cost of replacement.
Discoloration or mold growth. Seals that no longer seal trap moisture. Black or green growth on the seal or threshold means water is sitting there, and replacement is urgent.
We wrote more about preventing drafts and energy loss before winter hits, which walks through seasonal prep too.
Many Manor homeowners try to replace seals themselves using hardware store kits. The problem? Proper installation requires exact measurements, the right adhesive for your door's material, and tools most homeowners don't own. A misaligned seal will compress unevenly, fail faster, and leave gaps where you tried to cut corners.
Professional installation ensures the seal sits flush, compresses evenly, and lasts the full 4 to 7 years. The cost difference between a DIY attempt that fails in two years and a professional job that lasts six is minimal.

A basic weather stripping and seal replacement on a standard single-car door runs between $150 and $350, depending on the seal type and your door's age. Double-car doors or commercial applications cost more. We've detailed what to budget for weather stripping and seal repairs in a separate guide if you want exact pricing for your situation.
The timeline is fast. Most jobs take 1 to 2 hours from start to finish. If you schedule a free quote with Garage Door Manor, we'll assess your seals on the same call, explain what's needed, and often complete the work that day if you choose to move forward.
Summer heat and humidity in Manor stress seals more than moderate climates. Rubber hardens faster under UV exposure, and our occasional humidity spikes can cause swelling. Fall is the best season for replacement because you're preparing for cooler months and avoiding summer heat stress on the new seal.
If you're planning upgrades, also consider your door's insulation value. Worn seals often mean an older door that lacks proper insulation too. Check our guide to garage door insulation and R-value to see if a full door replacement might make sense alongside seal repair.
Worn weather stripping and seals don't fix themselves, and they cost more to ignore. A small draft today becomes an expensive energy leak tomorrow.

Your garage door keeps your home secure and efficient. Let's keep those seals working like new.
How do I know if my bottom seal is worn? Look for visible cracks, hardened rubber, or missing chunks. If you can see daylight under the door when it's closed, the seal has lost compression and needs replacement soon.
Can I replace just the bottom seal, or do I need to replace all seals? You can replace just the bottom seal, but side and top seals often wear at similar rates. We recommend inspecting all three during a service visit. Replacing all three at once ensures uniform protection and saves a second trip.
How much does weather stripping replacement cost near me? Most single-car garage doors run $150 to $350 for full seal replacement. Double-car doors and custom seals cost more. Call 17373214632 for a precise estimate for your door.
What happens if I don't replace worn seals? Drafts increase, energy bills rise, insects and dust enter your garage, and moisture can accumulate. Ignoring seals also stresses your garage door opener and frame over time.
How often should I inspect my seals? Inspect seals twice a year, ideally in spring and fall. Look for cracks, hardening, and gaps. Catch issues early to avoid emergency repairs or higher energy costs.
