Garage Door Perimeter Weatherstrip in Coldwater
Every time the door closes there is a rubbing squeal along one side, and the flexible fin has folded under itself and torn. Someone painted the trim last summer and painted the seal with it; now it is stiff as a board.
Garage Door Perimeter Weatherstrip
In plain words
The job follows a steady order. First the door is closed and the gaps are found from inside, by daylight and by feel. Then the door itself is checked for how it sits in the opening, since a seal only works against a door that is square to the frame. The jambs and header are inspected for rot and for how the old strip is fixed. The old material comes off, the surface is cleaned and repaired where needed, the header piece is fitted first and the sides after it, and the door is cycled several times to confirm nothing catches. You are shown the result with the lights off.
How the visit goesThe bedroom over the garage is always the cold room, and standing in the garage you can feel why: a steady draft along the door edges that moves the cobwebs on the wall. The seal around the opening has flattened to nothing.

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.
Replacing the wood stop with a one-piece vinyl stop
When the old wood stop is cracked, rotten or buried in paint, it is replaced rather than covered. The one-piece stop, a rigid vinyl moulding with the flexible fin formed along one edge, is cut on a mitre saw to header and side lengths and fitted the same way, header first. It needs no paint, does not rot, and its fin and stop are one part, so the seal cannot peel away from the moulding. Corners are either mitred or the sides butted tight under the header with the fins overlapped. The result looks like fresh trim and works as a seal.
A note of what was fitted
Before leaving, the technician tells you what went on: the seal type, the profile and fin width, the colour, and the lengths of the header and sides. It is worth writing this on a card near the opener or in the door's paperwork. If one length is ever damaged, by a ladder or a car mirror, the same profile can be matched and a single piece replaced rather than the whole set. If a jamb was repaired, the note records where and with what, so anyone painting or working on the frame later knows what is behind the finish.

What affects the quote
Same fees day, night or weekend
1Partial replacement
Replacing one damaged length rather than all three is a smaller job, provided the remaining pieces are still soft and the profile can be matched.
2Size 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.
3Weather on the day
Cold weather means keeping vinyl warm between the van and the opening and fitting each length with extra care, so a winter visit can run a little longer than one in mild weather.
Garage Door Perimeter Weatherstrip: questions
What are perimeter seals made of?
Most residential seals are flexible vinyl or a rubber compound formed into a fin that bends against the door. They come either as a flexible strip that is nailed to a wood stop or moulded onto a rigid vinyl stop as one piece. Commercial doors sometimes use an aluminum retainer holding a replaceable rubber insert, or a brush seal. Manufacturers make them to flex thousands of times as the door operates.
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.
Does it matter if my garage is detached and unheated?
The seal still earns its place. It keeps driven snow, rain, leaves and animals out of the garage and off whatever is stored there, and it stops the door edges rattling in the wind. For an attached or heated garage the comfort benefit to the house is added on top. The technician may suggest a simpler fin replacement for a detached shell and a one-piece stop where the garage is lived beside.
