A customer called last Tuesday asking why her electric bill spiked 40 dollars in May. After a quick inspection, I found the bottom seal on her garage door was cracked and peeling away from the frame. That single seal was letting conditioned air escape and hot Texas heat pour in. Weather stripping and seals are one of the easiest fixes we handle, yet homeowners overlook them until energy costs spike or bugs start appearing. If you're noticing drafts, seeing daylight under your door, or finding insects creeping in from the garage, your seals need attention now.
Texas heat is relentless. The sun bakes rubber seals year-round, and temperature swings from hot days to cooler nights cause expansion and contraction that cracks material over time. Most garage door seals last 5 to 8 years before they need replacement. If yours are original equipment and your home is older, they're likely past their lifespan.
Beyond age, poor installation and cheap materials accelerate failure. Some builders and contractors use seals that aren't rated for Weir's climate. Wind also plays a role. The bottom seal takes the most abuse because it's constantly flexed when the door opens and closes, plus it bears the weight of any debris or contact with the driveway.
When seals deteriorate, you lose the seal's primary job: creating an airtight barrier between your garage and the outside. That threshold between your garage and driveway becomes a gateway for heat, cold, drafts, moisture, and pests.
Replacing weather stripping and seals is one of the most cost-effective maintenance investments you can make. A complete seal replacement, including the bottom seal, side seals, and top seal, typically runs between 150 and 400 dollars depending on door size and material quality. Compare that to a 40 to 60 dollar monthly energy overcharge during summer, and the payback period is just a few months.
I've always believed in honest pricing. We don't upsell unnecessary work. If your seals still have rubber left and aren't letting visible light through, we'll tell you to wait. But if there's visible daylight, cracks, or gaps, replacement is the right call. You can read more about garage door pricing philosophy in our cost and pricing breakdown for Weir homeowners.

Most residential garage doors use three seal locations. The bottom seal is the most critical and the one that wears fastest. It's a rubber or vinyl blade that compresses against the concrete as the door closes, creating a tight fit. The side seals run vertically along both sides of the door frame, preventing drafts and keeping weather out. The top seal sits above the door opening and catches wind-driven rain.
Premium seals use durable rubber compounds rated for temperature extremes. Budget seals are thinner and fail sooner. We install seals that match your door's specifications and your climate. If you're also concerned about your door's overall condition, check our garage door safety guide to see if other maintenance is due.
When you call Garage Door Weir about weather stripping and seals, we can often schedule same-day or next-day installation. Most seal replacements take under two hours. We'll inspect the entire frame, check for rot or damage to the wood or metal, and recommend the right seal type for your door and budget.
The process is straightforward. We remove the old seal, clean the frame, measure twice, and install new stripping with proper compression. Proper installation matters more than the product itself. A good seal installed poorly won't seal properly. We've fixed plenty of jobs where corners were cut, and it cost the homeowner more in the long run.

How often should I replace garage door weather stripping? Most seals last 5 to 8 years in Texas heat. Inspect them annually for cracks, peeling, or hardening. If you see daylight under the door or feel drafts, replacement is overdue regardless of age.
Can I replace the bottom seal myself? The bottom seal is removable and some homeowners tackle it, but misalignment causes poor compression and drafts. Professional installation ensures the seal compresses evenly and actually stops air leakage.
What's the difference between rubber and vinyl seals? Rubber seals are more durable and flexible in extreme heat, lasting longer in Texas. Vinyl is cheaper upfront but hardens faster in sunlight. We recommend rubber for long-term value.
Will new seals reduce my cooling bill? Yes, noticeably. A leaking seal lets conditioned air escape. Proper seals can lower summer cooling costs by 20 to 30 percent, depending on how badly the old seals had degraded.
Do you offer warranties on seal installations? We stand behind our work with a one-year labor warranty on all seal replacements, plus the manufacturer's warranty on the seals themselves, typically 2 to 5 years.
