Garage Door Perimeter Weatherstrip
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 goesThe 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. It no longer bends toward the door at all.

How the visit goes
The corners and the meeting with the bottom seal
Gaps like to live where pieces meet. The technician looks at both top corners, where the header seal and the side seals should overlap so there is no square hole, and at both bottom corners, where the side seal should run right down to meet the bottom seal on the door. Mouse droppings, leaves and a small drift of snow in one corner are common finds and point to exactly which joint has opened. The bottom seal itself is noted; it is a separate part of the door, but if it is flattened or torn the household is told so both can be renewed in one visit if they wish.
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.
A continuous line of contact
The change is visible the moment the lights go off: no bright edge down either side, no glow along the top. From outside, the new stop or fin sits flush and matches the trim. When the door closes, the fin bends gently against it along its whole length and springs clear as it lifts, without a squeal or a drag. Snow that used to drift in along one side is largely kept out, and the garage stays quieter on a windy night. If a jamb was repaired, the fresh wood or PVC at the base is primed and painted so it reads as part of the frame rather than a patch.

What affects the quote
Same fees day, night or weekend
1Colour 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.
2Partial replacement
Replacing one damaged length rather than all three is a smaller job, provided the remaining pieces are still soft and the profile can be matched.
3Number of doors
Two or three doors on the same property share the set-up time and are quoted together, usually at less per opening than a single door on its own.
Garage Door Perimeter Weatherstrip: questions
How long does perimeter weatherstrip usually last?
It depends on sun, cold and how the door meets it. One manufacturer's guide suggests replacing seals every two to three years, while a well-set fin kept free of paint and wiped with silicone before winter often goes considerably longer. Rather than a calendar, watch the fin: when it stiffens, cracks or shrinks back from the door, it has done its work.
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.
What information helps when I book?
The size of the door and whether it is single or double, where you see daylight or feel drafts, whether the existing seal is a strip on a wood stop or a one-piece moulding, the colour of the trim, whether the wood near the floor feels soft, and whether the garage is attached or heated. Photos of the closed door from inside with the lights off, and of each corner from outside, are very useful.
