Garage Door Perimeter Weatherstrip in Cliffcrest
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
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.
How the visit goesA 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
Measuring for the new pieces
With the door closed, the header is measured across the full width of the opening and each side from header to floor, because openings are rarely the same on both sides. The profile is chosen to match the gap: a wider fin for a door that sits a little back from the stop, a narrower one where the gap is slight, and a one-piece stop where the wood is going. Colour is matched to the trim from a range of standard finishes. The technician also notes whether the existing stop projects far enough to cover the door edge, since a stop set too shallow leaves the fin working alone.
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.
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
Same fees day, night or weekend
1Size 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.
2Trim, brickmould and caulking
Re-caulking the joint between stop and trim, or dressing capping that channels water down the jamb, is small work done while the surface is bare and is listed on its own line.
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
How can I tell the side and top seal needs replacing?
Close the door, turn off the garage lights and look along the edges for daylight. Then press the fin with a thumb: it should be soft and spring back. Hardness, cracks, pieces missing, a strip hanging loose, snow or leaves inside along the edge, or a fin that has folded under and torn are all signs. A rubbing squeal as the door moves is another.
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.
Can the seal be replaced in winter?
Yes. The technician keeps the lengths warm in the van until the moment they are fitted, because cold vinyl is stiff and can split at a fastener, and works with the door closed so the garage is not open to the weather for long. Jamb repairs can be done in the cold as well. Many households have it done in autumn or winter because that is when the gaps make themselves felt.
