Garage Door Perimeter Weatherstrip

With the door closed and the garage lights off, a thin bright line runs down the whole left side of the opening. You can see the neighbour's fence through it.

In plain words

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.

The call
A length of weatherstrip along the right jamb has pulled away, nails and all, and it slaps against the trim every time the wind picks up. The wood behind it is dark and soft where it meets the floor.

How the visit goes

Technician reaching to the side track of a partly raised white garage door with small windows, a tool bag on the driveway.
  1. Scene 1

    Trim, cladding and where water gets behind

    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.

  2. Scene 2

    Fitting the sides and closing the corners

    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.

  3. Scene 3

    Keep paint off the fin

    When the trim is next painted, the flexible fin stays bare. Paint fills the flexible material and stiffens it, and a stiff fin cracks well before its time once the cold takes hold. If the rigid part of the stop is wood, it can be painted, but with the brush kept off the fin or the fin masked. One-piece vinyl stop needs no paint at all and simply washes clean. This single habit is the difference between a seal that stays soft for many years and one that fails early, and it is the most common cause of early failure the technician sees.

In the van

  • Exterior caulking and gun
  • Exterior screws and weatherproof staples
  • Epoxy consolidant and exterior primer
  • Vinyl stop moulding with integral seal
  • Jamb repair lumber or PVC trim

What shapes the quoteApplewood Hills Garage Door Co.

Fin 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.
Size 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.
Partial 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.

What people ask us

Why should the seal only touch the door lightly?

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.

What should I do before the technician arrives?

Move the car out of the garage or well back from the door, and clear anything stored against the jambs inside and any bins, planters or snow piled against them outside. Leave the door closed so the gaps can be seen as they are. If you have noticed where the daylight, drafts or snow come in, or where the mice appear, be ready to point it out.

Will a new seal make the room above my garage warmer?

It can help. Drafts around the garage door cool the garage, and the garage cools the floor above it and the wall it shares with the house. Closing the perimeter cuts those drafts, though how much warmer the garage runs depends on the door's own seal, the ceiling insulation and how the space is heated, not the perimeter alone. A technician can talk through those as separate steps if the room stays cold.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 38 in 100 homes · mixed ages
  • About 38% of homes in Mississauga were built in 1980 or earlier, according to the 2021 Census.Where housing ages are mixed, many older houses have already had a newer door and opener fitted, so the door's age and the house's age are not the same thing. The technician reads the door itself, its spring type, tracks and opener, before recommending anything.
  • Single-detached houses make up about 37% of homes in Mississauga (2021 Census).Townhouses built in rows tend to have identical doors from the same builder, so when springs and openers age they do so together along the street. Owners often arrange service for several doors at once, and we can plan a single visit that covers the row.
