Craftsman Weather Seal Replacement: The Boerne Owner’s Guide
We stock and install Craftsman-compatible weather seal replacement for most steel and aluminum door series, with typical installed pricing running $150-$280 depending on door width and seal type. Most Boerne homes with Craftsman doors use a 16-foot or 18-foot bottom seal retainer, and we carry both the bulb-style and T-style profiles on every truck. If you are seeing daylight under the door or finding water after a Hill Country downpour, the seal has likely compressed past recovery.
Homeowners usually notice the failure first in January or February, when a north wind pushes cold air straight through the garage and into the kitchen. Others catch it after a hard rain on Cascade Caverns Road or out near Scenic Loop, where water sheets across the slab and pools against the door. The seal looks fine from a distance. It is not fine.
Which Craftsman Models This Applies To
Craftsman garage doors sold through Sears and later through Lowe’s carried several series designations, and the weather seal profile changed between them. The 1/2-HP and 3/4-HP opener bundles from the 2000s typically shipped with steel doors using a single-channel T-style bottom seal, roughly 3 inches wide. The newer ReliaLift and AssureLink compatible doors moved to a wider, dual-bulb vinyl seal that slides into a U-shaped retainer. The part number is not stamped on the seal itself. You will find the door model on a sticker at the top interior panel or on the hinge side.
We carry OEM-grade EPDM rubber and high-density vinyl equivalents for both profiles. The aftermarket seals we stock are extruded to the same durometer and wall thickness as the original, which matters in Boerne because cheap PVC alternatives harden and crack within 18 months of summer heat and UV exposure. Carl Dutton keeps the original Craftsman spec sheets from 2004 forward in the truck binder, mostly because he hates making a second trip for the wrong part. We are an independent service provider, not affiliated with Craftsman or Sears Holdings.
Signs Your Craftsman Weather Seal Replacement Is Failing
- Visible daylight under the closed door. A healthy seal compresses to fill the gap between door and concrete, even on older slabs that have settled slightly. When the rubber or vinyl loses elasticity, it no longer expands to meet the floor. The gap may be pencil-thin and still admit dust, pollen, and scorpions.
- Water intrusion after rain. The Hill Country sees short, intense storms that overwhelm drainage. A compromised seal lets water sheet under the door and wick into stored boxes or wall framing. If you are running a shop vac after every rain, the seal is the first place to look.
- Increasing garage temperature swing. The seal is your thermal boundary. When it fails, the garage temperature tracks closer to outdoor conditions, which stresses any HVAC ducting running through the space and can freeze pipes on the north wall during Boerne’s occasional hard freeze.
- Cracking, flattening, or permanent compression set. EPDM rubber should rebound when pressed with a thumb. If it stays dented or shows alligator cracking along the contact face, the polymer has degraded. Vinyl seals turn stiff and develop a permanent “memory” of the closed position.
- Rodent or insect activity. A failed seal is an invitation. Mice need only a quarter-inch gap. We have found nests in the bottom rail of Craftsman doors where the seal gap went unaddressed through two seasons.
Replacement Cost & What’s Included
For a standard Craftsman weather seal replacement in Boerne, installed pricing typically runs $150-$280. A single 8-foot or 9-foot door with a straightforward T-style seal sits at the lower end. A 16-foot door with a dual-bulb profile, rusted retainer screws, or a slab that needs shim adjustment runs higher.
The price includes removal of the old seal, inspection of the aluminum or steel retainer for corrosion, installation of the new profile, and adjustment of door closing force so the seal compresses evenly without overloading the opener. We state the flat price before the wrench comes out. If the retainer itself is rotted through or the door bottom rail is damaged, we will show you and quote the additional work before proceeding. Every seal replacement carries our 90-Day Done Right Promise in writing.
DIY or Call Us?
A motivated homeowner can inspect the seal safely. Open the door manually to waist height, kneel, and run a hand along the bottom to feel for cracks or hard spots. Check the retainer screws for rust. That is where safe DIY ends.
Removing the old seal from the retainer channel requires feeding it out the end, which means detaching one or both bottom fixtures from the door track. On a torsion-spring door, the bottom fixtures are under cable tension. A slip here sends the fixture into your hand or face with force. We do not recommend homeowners attempt this. Our technicians arrive with the correct profile already cut to length, and most Craftsman seal replacements in Boerne are finished in under 45 minutes. Call (830) 365-0775 for a free estimate.
FAQs
A quality EPDM seal lasts 5 to 7 years in the Hill Country, though direct south exposure and poor drainage can shorten that to 3. The UV at 1,400 feet elevation is harder on vinyl than rubber. Call (830) 365-0775 if yours is showing age - estimates are free.
No. Once the rubber has lost its compression set or the vinyl has cracked, there is no adhesive or patch that restores the factory seal. Replacement is the only fix that lasts. We stock both profiles on the truck and can match yours in one visit.
Most Craftsman weather seal replacements take 30 to 60 minutes once we are on site. We cut the new seal to exact length in the truck, so there is no waiting. The door is fully operational when we leave.
Yes. We stock T-style and bulb-style seals in widths from 8 feet to 18 feet, plus the retainer hardware. For most Craftsman doors in Boerne, we complete the job in a single visit with no return trip needed.
