Garage Door Perimeter Weatherstrip in Craighurst
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
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 goesDry leaves keep appearing in the same corner inside the garage, and this fall there were mouse droppings along the wall beside the door. When you look, the corner where the top and side strips meet is wide open.

How the visit goes
A daylight test from inside
The first check needs no tools. The door is closed, the garage lights go off, and the technician stands inside looking along each side and across the header for lines of daylight. A bright, even line means the fin has shrunk back or hardened; a wedge that widens toward the top or bottom points to the door sitting out of square; a gap only at a corner means the pieces were never overlapped. On a windy day a hand or a smoke pencil along the edge finds drafts that daylight misses. The pattern of the gaps is what tells the technician whether the seal alone is the answer or whether the door needs a small adjustment first.
Cycling the door and sealing the joints
Once all three lengths are on, the door is run through several full cycles by hand and then with the opener, while the technician watches each fin for catching, folding or rubbing and listens for a squeal. The daylight test is repeated from inside with the lights off. Any joint between the new stop and the trim or brickmould where water could get behind is caulked with an exterior sealant, and the fin is wiped with a silicone spray to cut the odds of ice bonding it to the door. The old material is bagged and removed, and the household is walked round the finished opening.
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.

What affects the quote
Same fees day, night or weekend
1Fin 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.
2Doing 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.
3Size 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.
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.
