- The call
- After a windy night there is a fine ridge of snow on the garage floor along one side of the door, and another across the top step. The door was shut the whole time; the snow came in around it.

The vinyl strip around the door used to be soft and white. Now it is grey and hard, cracked every few inches, and a piece near the corner snaps off in your fingers.
Winter is what wears a perimeter seal out here. Sun and cold cycles harden the vinyl until it cracks, freezing rain glues the fin to the door so the opener tears it, and salty slush sits against the bottom of the jambs and rots the wood the strip is nailed to. One visit deals with all of that: soft wood at the base of the jamb is cut out and replaced, fresh seal is fitted in continuous lengths with the corners overlapped, and the fin is wiped with silicone so ice does not bond to it. The garage stays drier and calmer through the next freeze-thaw season.

Scene 1
The first check needs no tools. The door is closed, the garage lights go off, and the technician stands inside looking along each side and across the header for lines of daylight. A bright, even line means the fin has shrunk back or hardened; a wedge that widens toward the top or bottom points to the door sitting out of square; a gap only at a corner means the pieces were never overlapped. On a windy day a hand or a smoke pencil along the edge finds drafts that daylight misses. The pattern of the gaps is what tells the technician whether the seal alone is the answer or whether the door needs a small adjustment first.
Scene 2
Each side length is cut to run from tight under the header piece down to the floor, with a little spare to trim in place. It is set with the same light contact as the header and fastened top to bottom. At the top corner, the side fin tucks under the header fin so they overlap, leaving no square hole for drafts or mice. At the floor the side is trimmed to meet the bottom seal on the door, so the seal is continuous around three sides and hands off to the fourth. Both sides are done the same way, checking the door edge gap as they go.
Scene 3
The change is visible the moment the lights go off: no bright edge down either side, no glow along the top. From outside, the new stop or fin sits flush and matches the trim. When the door closes, the fin bends gently against it along its whole length and springs clear as it lifts, without a squeal or a drag. Snow that used to drift in along one side is largely kept out, and the garage stays quieter on a windy night. If a jamb was repaired, the fresh wood or PVC at the base is primed and painted so it reads as part of the frame rather than a patch.

The fin is meant to bend against the door with a small, even deflection. That is enough to seal, and it lets the fin spring clear as the door lifts. Pressed hard, it drags on the door face, folds under on the way down, squeals and wears through well before its time, and it adds load to the opener. Set too far off, it leaves a standing gap. The light touch is the setting that lasts.
A little, though it is not the main reason to do it. A fresh bottom seal cushions the door's contact with the floor, and snug side and top seals stop the panel rattling against loose or worn stops. Most of the noise people notice from a garage door comes from rollers, hinges and the opener chain or belt rather than the seals, so a technician checking the weatherstrip will usually point out those parts too if they are the louder culprit.
Yes, and the rot is handled first. The soft wood at the base of the jamb is cut back to sound material and a new piece of lumber or PVC trim is spliced in, fixed and primed, so the fasteners for the new stop bite into something solid. This is one of the most common additions to a perimeter seal job here, because slush and salt sit against the jamb base all winter.
