The four seals and what each costs
- Bottom seal. The rubber or vinyl bulb along the door's bottom edge. On most doors it slides into an aluminum retainer; if the retainer itself is corroded or bent, replacing it adds a little to the job. This is the seal that fails first and matters most.
- Side and top perimeter seal. The vinyl flap nailed to the jamb that closes the gap around the door face. Sun-baked ones crack and curl, and you can often see daylight past them from inside.
- Threshold seal. A raised rubber strip glued to the slab under the door, for garages where wind-driven rain sheets under the bottom seal. Common fix on driveways that slope toward the house.
- Between-panel seals. Built into modern doors; if panels no longer meet cleanly the issue is usually alignment, not stripping, and that is a repair call.
Why seals die fast in central Oklahoma
Rubber that lives through metro weather has a hard career. Triple-digit slab temperatures in August cook the plasticizers out of vinyl, then the first ice storm freezes the stiffened seal to the concrete, and the next opener cycle tears a chunk off. We replace far more bottom seals in the two weeks after a hard freeze than any other time; the quick prevention tip is a stripe of silicone spray on the rubber before freezing nights. Add red-dirt grit blowing under the door on every south wind, and a seal that lasts a decade in a mild climate gives you five to seven years here.
Signs yours is finished: daylight under a closed door, dust lines inside the garage after windy days, water intrusion during storms, or rodent evidence each fall. Mice need barely a quarter inch, and a hardened seal corner is their front door.
Worth doing alone or bundling?
Weather stripping is a fine standalone service call, but the economics improve when it rides along with other work. The labor overlaps almost entirely with a tune-up, so bundling both usually saves money versus separate visits, and a tech already inspecting cables and springs will spot whether the "gap under the door" is actually a sagging bottom section or an out-of-level slab, both common in older Del City and Midwest City garages where the concrete has settled. One thing new seals cannot fix is an uninsulated door radiating heat; if comfort is the underlying complaint, our comparison of insulated versus non-insulated door costs addresses the actual lever.
