Garage Door Perimeter Weatherstrip

The vinyl strip around the door used to be soft and white. Now it is grey and hard, cracked every few inches, and a piece near the corner snaps off in your fingers.

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.

Sound familiar?

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.

How the visit goes

Mississauga

How the visit goes

  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. Fastening that lasts through the seasons

    Fasteners are chosen for the weather they will live in: galvanized or stainless trim nails, exterior screws where the stop is heavy or the wood is hard, and weatherproof staples only for a light fin on sound wood. They are spaced evenly so the strip stays straight between them, and a nail set is used so the heads sit flush without crushing the vinyl. In cold weather the lengths are kept warm in the van until the moment they are fitted, because cold vinyl is brittle and splits at the ends. Fasteners near the end of each piece go in a little further back for the same reason.

  3. A look round each season

    The simplest care is a glance four times a year. Close the door, switch off the lights and look along both sides and the header for daylight. Then step outside and check that no length has lifted, that the corners are still tucked together and that the fin is still soft when you press it with a thumb. Cracks, a hard grey surface or a piece that has shrunk back from the door are the early signs. Manufacturers suggest wiping the seal down with a damp cloth a few times a year, and that also lets you feel any change in it.

What affects the quote

Same fees day, night or weekend

  1. 1Weather 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.

  2. 2Working height and access

    A tall header, a sloped driveway that makes a ladder awkward, shrubs against the jambs or cars and storage close to the door all affect how long the work takes.

  3. 3Doing 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.

Garage Door Perimeter Weatherstrip: questions

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.

The wood around my door is rotten near the floor. Can the seal still go on?

Yes, and the rot is handled first. The soft wood at the base of the jamb is cut back to sound material and a new piece of lumber or PVC trim is spliced in, fixed and primed, so the fasteners for the new stop bite into something solid. This is one of the most common additions to a perimeter seal job here, because slush and salt sit against the jamb base all winter.

How should I look after the new seal?

Four times a year, check for daylight from inside with the lights off and press the fin to feel that it is still soft. Wipe the seal with a damp cloth to clear grit and salt, keep paint off the fin, apply a silicone wipe before winter, and keep slush and bins away from the bottom of the jambs. Press any lifted corner back and call if a length has come loose.
