- 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.

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.
Around a garage door there are three seals: one on the bottom edge of the door, and two running up the sides and across the top of the opening. Those last two are the perimeter weatherstrip. They are fixed to the stop moulding on the jambs and header, and their flexible fin rests against the door face when it is closed, closing the gap between door and frame. Replacing them means fitting new lengths that meet the door evenly, cutting down how much wind, driven snow, dust, leaves and small animals get through. The bottom seal is handled as its own job, but the two are often done together.

Scene 1
The seal shares the jamb with brickmould, siding, capping and old caulking, and water that gets behind any of them ends up in the wood the strip is nailed to. The technician follows the joint between stop and trim looking for cracked or missing caulk, capping that funnels water down the jamb face, and gaps at the sill where meltwater collects. These are small things to correct while the old strip is off and the surface is bare, and they are what stop the fresh wood from going the way of the old. Anything larger, such as damaged siding, is pointed out for a separate decision.
Scene 2
With the door closed, the header length is cut to the full width of the opening and lifted into place, a two-person job on a double door. It is positioned so its fin lies against the top section with a slight, even deflection along the whole width, then fastened from the centre outward with galvanized or stainless nails or exterior screws at regular spacing, which keeps the length straight rather than letting it wander. The ends are left to receive the side pieces beneath them. Fitting the header first means both sides are cut to meet it exactly, and the corners close properly.
Scene 3
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.

FeesSame any hour
A straightforward fin replacement on a single door is often a matter of an hour or two once the technician is set up; a double door with a one-piece stop takes longer, and any jamb repair adds to it. Most of the time goes into checking the door, preparing the surface and setting the contact carefully, since those are what make the seal last. You are given a sense of the timing when the work is confirmed.
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.
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.
