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. The door was shut the whole time; the snow came in around it.
Garage Door Perimeter Weatherstrip
In plain words
A perimeter seal is only as good as the door it meets, so a technician looks at the door before the seal. If one side shows daylight and the other is tight, the strip may be fine and the door may have drifted: worn rollers, a track bracket that has moved, a top section that bows away from the header. Setting that right first means the new fin can be positioned with the same light contact on every side. Where the door is already square, the seal is fitted straight to it. Either way the result is a door that closes against a continuous line of contact.
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.
Setting the fin against the door
Getting the fin's contact right is the heart of the work. The technician holds each length against the closed door and adjusts it until the fin bends toward the door just enough to seal without pushing back. A fin set too far off leaves a standing gap that shows as daylight; one set too hard drags the door, folds under on the way down and wears through well before its time. Contact is checked at several points along each side, since a jamb is rarely dead straight, and the fastener positions follow the door face rather than the wood behind it.
A note of what was fitted
Before leaving, the technician tells you what went on: the seal type, the profile and fin width, the colour, and the lengths of the header and sides. It is worth writing this on a card near the opener or in the door's paperwork. If one length is ever damaged, by a ladder or a car mirror, the same profile can be matched and a single piece replaced rather than the whole set. If a jamb was repaired, the note records where and with what, so anyone painting or working on the frame later knows what is behind the finish.

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.
2Commercial or oversized openings
Wider and taller commercial doors often carry an aluminum retainer with a rubber insert or a brush seal, and the material and fitting time differ from a residential vinyl seal.
3Colour and profile
Standard colours and fin widths are carried on the truck. A less common colour, an extra-wide fin or a commercial retainer with insert may be a special order, with the difference noted.
Garage Door Perimeter Weatherstrip: questions
My door was replaced last year. Does the perimeter seal need doing too?
Often, yes. A new door is sometimes fitted against the original wood stop and its old fin, and the new door may sit slightly differently in the opening, so the old seal no longer meets it. If daylight shows at the edges or the fin is hard and cracked, a new seal set against the new door completes the installation and matches the fresh look of the door.
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.
Does new weatherstrip make the door any quieter when it opens and closes?
A little, though it is not the main reason to do it. A fresh bottom seal cushions the door's contact with the floor, and snug side and top seals stop the panel rattling against loose or worn stops. Most of the noise people notice from a garage door comes from rollers, hinges and the opener chain or belt rather than the seals, so a technician checking the weatherstrip will usually point out those parts too if they are the louder culprit.
