Clopay weather seal replacement in San Antonio typically runs $85 – $160 installed, depending on door width and seal profile, and we carry the common Clopay-compatible profiles on the truck for same-day install. Most homeowners discover the seal has failed the same way: a line of daylight under the door, leaves and dust blowing into the garage, or a utility bill that creeps up in August. The bottom seal on any garage door is a wear item, and in San Antonio’s heat, it degrades faster than the manufacturer’s general lifespan estimate because rubber compounds don’t love 100-degree afternoons followed by 40-degree winter nights.
We’re an independent service provider, not affiliated with Clopay, but we stock and install seals that match Clopay’s profiles exactly. If your door is a Clopay and the bottom seal is cracked, flattened, or pulling away from the retainer, you’re on the right page.
Which Clopay Models This Applies To
Clopay has used several bottom seal profiles across its residential lines over the years, and the wrong seal won’t seat in the retainer. Most Clopay doors built in the last 15-plus years, including the Gallery, Coachman, and Value Plus series, use a T-channel or bead-style seal that slides into an aluminum retainer at the bottom of the door. Older Clopay models, and some commercial units, use a U-shaped astragal that wraps the bottom edge and mechanically fastens. The quickest way to identify what you need is to look at the bottom edge of the door: a T-channel seal bulges out from a track, while a U-astragal hugs the door from both sides.
We match by profile and width, not just by brand, because Clopay’s own specs have shifted over time. A common gotcha we see in San Antonio: homeowners buy a generic big-box seal that looks close, force it into the Clopay retainer, and the seal pops out within weeks because the bulb diameter is wrong. On the OEM versus aftermarket question, we install what works best for your specific door. Some Clopay profiles are worth buying OEM-equivalent for exact fit; others are commodity rubber and a quality aftermarket seal is indistinguishable in performance. We’ll tell you which is which on your door, honestly.
Styles & brands we work with






Signs Your Clopay Weather Seal Replacement Is Failing
- Visible daylight under the closed door. The seal has compressed, cracked, or pulled away from the retainer. When you stand inside the closed garage and see a line of light, water and air are getting through the same gap.
- Water pooling or staining near the door threshold. A flattened bottom seal stops channeling rainwater away from the garage floor. San Antonio downpours will find every gap. If you see damp spots after a storm, the seal is suspect.
- Dried, cracked, or brittle rubber. UV exposure and San Antonio heat will leach the plasticizers out of a vinyl seal, leaving it hard and split. Flex the seal by hand: if it feels like stale bread instead of rubber, it’s done.
- Leaves, dirt, or pests getting in. The seal isn’t just about water. A lifted or worn seal leaves enough room for roaches, crickets, and field mice. San Antonio’s hot, dry stretches drive insects toward the cooler space under a garage door.
- Higher energy bills without another explanation. A failed bottom seal lets conditioned air escape and attic-like heat in. It’s rarely the main culprit, but it’s always a contributor on an unsealed garage.

AfterReplacement Cost & What’s Included
For Clopay-compatible bottom seal replacement in San Antonio, you’re looking at $85 – $160 installed for a standard two-car door. The range mostly reflects door width and seal material: vinyl lasts longer in heat and costs a bit more than standard rubber, and wider doors need longer runs. The price includes the seal material and the labor to remove the old one, clean the retainer, and seat the new seal correctly.
Where we land within that range depends on what your Clopay door actually needs, and you’ll know the number before anything happens. Every job gets a written price before we touch a tool, and every seal replacement is covered by the 365-Day Done Right Promise. If the seal fails within a year, we come back and make it right at no charge. No fine print, no prorated nonsense.
DIY or Call Us?
Weather seal replacement is one of the safer garage door repairs to attempt, but getting the old seal out of a long aluminum retainer without bending it is where DIY goes sideways. The retainer is extruded aluminum, and once it’s kinked, the new seal can’t slide through evenly. You’ll end up with a scalloped, leaky fit. For T-channel seals, the job requires pulling the old rubber straight out without tearing it, then lubricating the new run and sliding it through without the retainer flexing off the door.
If you’re handy, have an undamaged retainer, and don’t mind an hour on the garage floor, it’s doable. If the retainer is corroded, bent, or missing screws, or if you’d simply rather not fight it, call (361) 314-2738 and we’ll handle it. Jaylen Ross and the Marlow crew do this particular job on Clopay doors across San Antonio multiple times a week; there’s no guesswork left.
FAQs
A Clopay bottom seal in San Antonio typically lasts 3 to 5 years, which is shorter than the 5-to-7 year lifespan you might see in milder climates because our UV index and sustained summer heat harden the rubber faster. If your door faces west with no shade, expect the shorter end of that range. A simple visual check once a season will tell you where your seal is in its lifespan. If it looks cracked or no longer makes full contact with the floor, give us a call at (361) 314-2738 and we’ll give you an honest read and a free estimate.
Generally no. Once the seal material is cracked, flattened, or pulling away from the retainer, patching it is a temporary fix that typically fails within months. The material itself is compromised, and the seal’s job is a full-width, continuous contact line against the floor. Replacing the run is the honest fix, and at $85 – $160 installed, it’s priced to just be done right once. Call (361) 314-2738 to get a free estimate before you commit to anything.
Most Clopay weather seal replacements take 30 to 45 minutes for a standard two-car door, start to finish. If there’s retainer damage, add a little time to straighten or re-fasten it. When you book with us, you’ll get a live arrival window you can track, so you’re not sitting around waiting.
Yes. We keep the common Clopay T-channel and U-astragal profiles in the truck, along with seals for LiftMaster, Chamberlain, and Genie openers’ associated door hardware. If your door takes an unusual profile or width, we’ll bring it out on the second visit at no additional service-call charge, and your written quote will reflect that before we start.
No. The price we quote in writing before starting is the price you pay. If we find something unexpected while working on your Clopay seal, we stop, show you what we found, and give you a revised written price before doing anything else. The number on the invoice matches the number you agreed to, every time.
