Garage Door Perimeter Weatherstrip
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.
In plain words
For an attached garage the perimeter seal does more than keep leaves out. The garage is a buffer between the weather and the house, and drafts around the door cool the wall it shares with the kitchen and the floor of the room above it. Snow blown in melts and refreezes on the slab, and mice follow the warm air in at open corners. A well-fitted side and header seal closes those paths and eases the job of the weatherstripped door between garage and house, though the garage's warmth also depends on the door's own seal, the ceiling and the heating. It is a worthwhile comfort improvement for the house.
How the visit goesEvery 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
What has been getting in, and what the garage is for
A short conversation shapes the rest of the visit. Is the garage attached and heated, or a detached shell? Has snow, water, leaves or an animal been coming in, and where? Is the door used several times a day or once a week? Was the door itself replaced or adjusted recently? A heated garage under a bedroom justifies a full one-piece stop and careful corners; a detached garage used for storage may want a straightforward fin replacement. Knowing what the household has noticed also tells the technician which side to test first and whether a section of jamb has been wet for a long time.
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.
Corners that stay closed to pests
With the header and side fins overlapped, the small square holes that mice and wasps used are gone. Keep them that way by checking the four corners each autumn, when animals are looking for warmth, and pressing any lifted corner back into place. The point where the side seal meets the bottom seal on the door is worth a look too, since the bottom seal wears on its own schedule. A clear threshold, with leaves swept away from the door, removes the shelter pests use to work at a corner. Sealing the perimeter is one of the simpler parts of keeping a garage pest-free.

What affects the quote
Removing the old stop and paint build-up
Lifting a wood stop that has been painted for decades, scraping old adhesive and knocking down paint ridges takes longer than pulling a loose fin, and the time shows in the quote.
Alignment 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.
Working 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.
What to have ready
- Where do you see daylight, drafts or snow: sides, top, or corners?
- What colour is the trim around the door?
- Is the bottom seal on the door also worn?
Garage Door Perimeter Weatherstrip: questions
QuestionsHow 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.
What colours does perimeter weatherstrip come in?
Standard ranges cover white, almond, brown, grey, black and a sandstone or clay tone, which between them match most trim, garage door and brickmould colours. The technician brings the colour that suits your trim once you describe it or send a photo. A one-piece vinyl stop is coloured through, so it does not show scratches, and a fin on a painted wood stop can be matched to the paint.
Do you adjust the door as part of the seal work?
Small corrections, yes. If a track bracket needs re-setting or the door needs to come plumb so the fin can meet it evenly, that is done so the new seal is fitted to a door that sits properly. Larger work, such as replacing rollers or a bowed section, is explained and offered as its own job so you can decide on it separately.
