Garage Door Perimeter Weatherstrip
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.
Garage Door Perimeter Weatherstrip
In plain words
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.
How the visit goesThe new door went in last year and looks perfect, but the old wooden stop and its tired seal were left in place. Along the top there is a gap you could slide a finger into, and the cold pours through it.

How the visit goes
Probing the jambs and header
The strip is only as secure as the wood behind it, so the jambs are probed with an awl along their length and especially the lowest part, where slush and salt sit all winter. Soft, dark or crumbling wood is marked for repair. The header is checked for sag and for gaps opening between it and the top section. Where the jambs are clad in aluminum or vinyl, the technician looks for what the cladding hides and for where the seal can be fastened through to solid material. This step often adds a splice of new lumber or PVC trim to the job, and it is what makes the new seal stay put.
Cycling the door and sealing the joints
Once all three lengths are on, the door is run through several full cycles by hand and then with the opener, while the technician watches each fin for catching, folding or rubbing and listens for a squeal. The daylight test is repeated from inside with the lights off. Any joint between the new stop and the trim or brickmould where water could get behind is caulked with an exterior sealant, and the fin is wiped with a silicone spray to cut the odds of ice bonding it to the door. The old material is bagged and removed, and the household is walked round the finished opening.
A continuous line of contact
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.

What affects the quote
Same fees day, night or weekend
1Fin on the existing stop or a one-piece vinyl stop
Nailing a new fin to a sound wood stop uses less material than replacing the stop with a one-piece vinyl moulding, which costs more as a part but needs no paint and does not rot.
2Doing the bottom seal at the same time
When the bottom seal on the door is also worn, renewing it during the same visit is offered as a separate line and saves the cost of a second call.
3Size of the door
A double door has a longer header and the same two sides as a single, so more material and a two-person lift for the top piece; taller openings take longer side lengths.
Garage Door Perimeter Weatherstrip: questions
Do you adjust the door as part of the seal work?
Small corrections, yes. If a track bracket needs re-setting or the door needs to come plumb so the fin can meet it evenly, that is done so the new seal is fitted to a door that sits properly. Larger work, such as replacing rollers or a bowed section, is explained and offered as its own job so you can decide on it separately.
How is the seal fastened to the frame?
A flexible fin is nailed or stapled to the face of the wood stop with galvanized or stainless fasteners spaced evenly along its length; a one-piece vinyl stop is nailed or screwed through its rigid edge into the jamb and header. Fasteners go into sound wood, heads are set flush without crushing the vinyl, and the joint between stop and trim is caulked where water could get behind.
Will replacing the perimeter seal keep mice out?
It closes one of their favourite routes. Mice enter at the open corners where the header and side seals meet and along a fin that has shrunk back from the door, so a continuous, overlapped seal removes those gaps. It works alongside a sound bottom seal, a swept threshold and attention to any other openings in the garage wall, and a technician will point out any of those noticed during the visit.
