Replacing a Clopay weather seal in San Antonio typically runs $110 – $280 installed, depending on whether it’s the bottom seal, the side jambs, or the top header strip. We carry Clopay-compatible seals on our trucks, so most swaps happen the same day we arrive. The part itself is usually under $40; what you’re paying for is getting the old brittle rubber out of the T-channel without damaging the retainer and making sure the new seal actually meets the floor evenly.
Most homeowners discover the failure the same way: a line of daylight under the door, a puddle near the water heater after a Hill Country downpour, or leaves that somehow keep finding their way into an otherwise clean garage. Sometimes it’s the smell of exhaust creeping in from a car idling in the driveway. The seal looks fine from ten feet away. Up close, it’s cracked, flattened, or torn at the corner where the door meets the concrete.
Which Clopay Models This Applies To
We install weather seal replacement on every Clopay residential line sold in the San Antonio market: the Gallery, Bridgeport, Coachman, Grand Harbor, and the entry-level Classic series. The compatibility gotcha that trips up a lot of DIY buyers is the retainer channel. Clopay uses both a single T-channel and a barbed press-in channel depending on the door’s age and series, and they are not interchangeable. A seal that slides into a 2016 Gallery door will not press-fit into a 2008 Classic rail without adapting the channel itself. That’s the kind of thing you only learn by pulling the old seal out in a driveway.
For OEM versus aftermarket: Clopay branded seals are fine, and we stock them, but the aftermarket T-style rubber we carry in 3-inch, 5-inch, and 7-inch widths performs as well in Texas heat for about 30% less. What matters more than the brand is the durometer, the material hardness. Soft EPDM rubber compresses and seals well but degrades faster under San Antonio’s UV load. A slightly firmer rubber lasts longer but needs the door to be adjusted properly or it will leave gaps on an uneven slab. We match the seal to the floor, not just to the door.
Styles & brands we work with
Signs Your Clopay Weather Seal Replacement Is Failing
- Visible daylight under the door. The seal has compressed or torn. If the light is only on one side, the door may also be out of level, which will destroy a brand-new seal within a year if it isn’t corrected during installation.
- Water pooling near the garage door after rain. San Antonio gets fast, heavy storms. A failed bottom seal lets runoff pour under the door and across the slab. The water line usually points straight at the problem.
- Cracked or crumbled rubber when you touch it. UV exposure and summer heat cycles harden elastomer over time. When the seal cracks instead of flexing, it’s done. Replacement is the only fix.
- Pest droppings or insect entry along the door perimeter. The side and top seals don’t just block weather; they block the gaps that critters use. If you’re finding roach activity or geckos near the tracks, check the jamb seals.
- Wind noise or hot air leaking around the door edges. When the seal no longer makes contact with the jamb, you’ll hear the wind whistle through the gap. In August, you’ll feel it as warm air along the wall.
Replacement Cost & What’s Included
For San Antonio homes, here is what you should expect to pay for a Clopay weather seal replacement:
- Bottom seal only: $110 – $180 installed, including the rubber and any T-channel cleanout.
- Bottom seal plus side jambs and top header: $180 – $280 installed for a full perimeter refresh.
- Retainer/channel replacement if the original is bent or corroded: add $60 – $90.
The price is written down and handed to you before a single screw comes out. It includes removing the old seal, cleaning the channel, cutting the new rubber to fit the exact door width, installing it, and adjusting the door so the seal contacts the floor evenly. We don’t quote weather seal work over the phone sight unseen; Aaron Teague has a firm rule about that. The condition of the retainer and the flatness of the slab change the labor, and you don’t know either until you’re standing in the garage looking at the door.
Every seal replacement carries our 365-Day Done Right Promise: if the seal tears, shifts, or leaks within 365 days from the date of the repair, we come back and make it right at no charge. No argument, no prorating, no fine print. We also offer a free second visit if the repair fails, covered automatically.

Weather seal replacement is one of the few garage door jobs where a capable DIYer can save money. The seal itself doesn’t have tension the way springs and cables do. If you can identify the retainer type and muscle the old rubber out, you can slide in a new section and call it a weekend project. What goes wrong in practice: the seal won’t seat because the channel is full of old rubber fragments, the door is out of balance so the seal catches the slab, or someone buys the wrong width online and has a new seal that’s as useless as the old one.
If the door isn’t level or the retainer is damaged, that’s when we’d recommend calling us before you spend money on parts. We see San Antonio garages with slabs that have shifted two inches from one side to the other, and a sealed perimeter is only possible if you address the door first. That’s not a lecture; it just saves you buying the same seal twice. If you’d rather have it done in one visit, call (806) 491-1594.
Frequently Asked Questions
A Clopay weather seal in San Antonio typically lasts 3 to 5 years, depending on sun exposure and how often the door is used. South-facing garages in hot neighborhoods like Stone Oak and Alamo Ranch wear through seals noticeably faster because the concrete holds heat and bakes the rubber from below. Plan on replacement every few seasons, and check it each spring.
No. Once the rubber is cracked, compressed, or torn, you cannot patch it back to a working seal. The only reliable fix is new rubber installed into a clean channel. Any attempt to glue or splice a seal will fail within weeks, and the first hard rain will find the seam.
A bottom seal swap takes 30 to 45 minutes. A full perimeter replacement with side and top seals takes about an hour and a half. This is a quick job compared to spring or opener work, and we can usually complete it the same day we arrive.
Yes. We carry Clopay-compatible T-style and barbed seals in the most common widths, plus replacement retainers for older doors whose channels are too corroded to reuse. If you need a specific OEM seal we don’t have on hand, we can have it within one to two business days. We also stock parts for LiftMaster, Chamberlain, and Genie, so if the seal is only part of your door’s problem, we can handle the rest in one visit.
