Garage Door Perimeter Weatherstrip
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
Perimeter seal comes in two common forms, and the visit begins by deciding which suits your opening. The simpler is a flexible vinyl fin nailed to the face of the existing wood stop, which works well where the stop is sound. The other is a one-piece vinyl stop moulding with the fin built in, which replaces the wood stop altogether and suits jambs that are weathered or where the old stop is cracked and paint-heavy. Commercial doors sometimes carry an aluminum retainer with a replaceable rubber insert. Each is cut to your header and sides on site and set against the closed door.
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.
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.
Slush, salt and the bottom of the jambs
The lowest part of each jamb is where the weather does its work, so a little attention there protects the whole seal. Push slush away from the jambs when clearing the driveway rather than piling it against them, and rinse the salt off the bottom of the stop on a mild day. Keep the joint between the jamb and the sill caulked so meltwater runs off the face instead of behind it. If a section of jamb was replaced, keep its paint or PVC surface intact. A dry jamb base holds its fasteners, and fasteners that hold keep the seal tight.

What affects the quote
Same fees day, night or weekend
1Alignment work on the door
Where the door sits out of square and a track bracket or the door itself needs small correction before the seal can meet it evenly, that adjustment is named separately.
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.
3Corner detailing
Mitred corners on a one-piece stop, or fitting round an unusual trim profile, take more cutting and fitting than butted corners on a plain jamb.
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.
