We stock and install Raynor-compatible weather seal replacement in San Antonio for $95 – $160 installed, including the part, most days the same day you call. The seal is the rubber strip along the bottom of your door (and sometimes the side jambs) that keeps water, dirt, leaves, bugs, and Texas heat from pushing into your garage. Most San Antonio owners discover theirs has failed by spotting daylight under the door, sweeping out fine dust after every windstorm, or noticing the garage got oddly hot in July. If the rubber is cracked, flattened, or pulling loose from the retainer, that’s your answer. We bring the replacement seal on the truck, match it to your door, and you get a written price before we touch a tool.
Which Raynor Models This Applies To
Weather seal is one of the few parts that’s nearly universal across the Raynor line. Whether you have a Builder Series door from a 2000s San Antonio track home, a ShowCase model, an Aspen AP200, or a newer aluminum-framed Raynor with a bulb-style P-seal, the bottom rubber wears and needs replacement. The key gotcha is the retainer style: Raynor doors use a T-channel or U-channel aluminum retainer, and a generic seal from a big-box store often won’t seat correctly. We stock T-style and J-style seals for Raynor in both 3-inch and 4-inch widths, and we can tell within seconds which one your door takes by checking the channel opening. For most residential Raynor doors, the seal is sold by the foot, and standard widths run 8, 9, 16, or 18 feet.
OEM vs. aftermarket: Raynor-branded weather seal is fine, but premium aftermarket equivalents like Atco and Ulti-Seal often outlast OEM by a few years because the rubber compound is thicker and more UV-resistant. We’ll install either. The thing that matters more than brand is fit. A seal that’s too short means you still get daylight and pests. Too long means it folds, catches, and tears off at the bottom corners.
Styles & brands we work with






Signs Your Raynor Weather Seal Replacement Is Failing
- You can see daylight under the door. The most obvious one. If you can slide a pencil under the door at any point, the seal has compressed or lost contact with the slab. Water and bugs are already getting through.
- Dust and fine dirt collect inside the garage. San Antonio’s wind kicks up a lot of fine calcium dust. A healthy seal blocks most of it. If your floor has a permanent red-brown film, your seal stopped doing its job months ago.
- Water puddles at the bottom panel after rain. Even a quarter-inch gap lets sideways rain in. You’ll see stains on the inside panel or wet floor right at the door line.
- The bottom of the door scrapes or catches. If the rubber has torn and balled up in the track, you’ll hear a grinding or feel resistance when the door moves. That’s not spring trouble, it’s seal debris.
- Bugs and spiders appear in the garage more often. Scorpions and crickets want shade and a crack. The seal is your barrier. If it’s gapped, they’ll find it.

AfterReplacement Cost & What’s Included
In San Antonio, Raynor weather seal replacement runs $95 – $160 installed. A basic 16-foot T-style seal install is on the lower end; a longer door, a two-car wide door with worn-out retainer that needs cleanup, or a higher-grade UV-resistant seal pushes it to the top of the range. What’s included: the correct seal matched to your Raynor retainer, removal of the old rubber, trimming to exact length, seating it straight, and confirming the door closes on level contact. You’ll see the written price before we begin, and the work is covered by our 365-Day Done Right Promise: if it fails within a year, we come back and make it right at no charge.
| Seal Type | Typical Installed Price |
|---|---|
| Standard T-style, 8′ – 9′ door | $95 – $120 |
| Standard T-style, 16′ door | $110 – $140 |
| Premium UV-resistant material, 16′ door | $140 – $160 |
DIY or Call Us?
Weather seal is one of the few garage door parts an alert homeowner can replace without real risk, because it doesn’t involve the torsion spring or cable tension. The honest split: if your current seal slides out of the retainer and you can measure the width and channel shape, a careful DIY swap is doable for about $40 in materials. Where DIY goes wrong in San Antonio is the measurement step. Buy the wrong channel style or cut it an inch short, and you’ll have the same gap you started with, plus a wasted afternoon. Also, never attempt to replace a seal while the door is open with spring tension loaded. If the bottom retainer is bent, corroded, or full of hardened rubber, call us at (361) 314-2738 and we’ll have it sorted in under an hour, seal included.
FAQs
Expect 3 to 5 years on a garage that faces direct afternoon sun, because our UV intensity and summer heat break down the rubber faster than in cooler climates. Shaded garages can get 6-plus years. If you’re replacing it more often than that, ask us about a premium UV-resistant compound.
Mostly no. If a section has torn or flattened, patching doesn’t last because the seam catches debris and opens again. Replacement is faster and cheaper than a repair attempt that fails in a month. If the retainer is in good shape, we just pull the old rubber and slide in new.
Most Raynor weather seal swaps take 30 to 45 minutes from arrival to finish. That includes removing the old seal, cleaning the retainer channel, cutting the new one to length, and testing the door’s close.
Yes. We carry T-style and J-style seals in 3-inch and 4-inch widths for Raynor doors, along with compatible parts for LiftMaster, Chamberlain, and Genie openers. If your door uses an uncommon size, we can typically source it same-day from our San Antonio parts network. Call (361) 314-2738 and we’ll confirm your model before we dispatch.
The price we quote you on the phone is the price on the written estimate. If we find extra work (like a badly bent retainer), we show you the separate line item and you approve it before we do anything. No surprises at the end.
