Garage Door Perimeter Weatherstrip in Adelaide-Metcalfe
Every time the door closes there is a rubbing squeal along one side, and the flexible fin has folded under itself and torn.
In plain words
The skill in this job is in the position of the fin. It should touch the door with a small, even deflection, so that it seals when the door is closed and springs clear as the door lifts. Set too far off, it leaves a standing gap; pushed too hard, it drags, folds under and tears within a season. The header piece goes on first, fastened from the centre outward so it stays straight, and the sides are fitted tight beneath it so the fins overlap at the corners. Fasteners are spaced evenly in sound wood, and any joint where water could get behind the stop is caulked.
How the visit goesWith the door closed and the garage lights off, a thin bright line runs down the whole left side of the opening. You can see the neighbour's fence through it. The strip that should close that gap has shrunk back from the door.

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.
Making the jamb sound
Where probing found soft wood, it is dealt with before the seal. Rot at the base of the jamb is cut back to solid material and a matching piece of lumber or PVC trim is spliced in, fixed and primed. Minor soft spots are hardened with an epoxy consolidant and filled. Fasteners that will hold the new stop are then going into wood that grips them, which is what keeps the strip tight through years of the door pressing on it. Where the jamb is clad, the technician finds the solid framing behind the cladding and fastens through to it rather than into the thin skin.
Before the freezing rain
In late autumn, wipe the fin with a silicone spray or a silicone-based lubricant on a cloth. It leaves a film that cuts the odds of meltwater bonding the fin to the cold door face during an ice storm, though a hard freeze can still catch it. Oil-based products are avoided because they swell and soften vinyl over time. The same wipe once or twice through the winter keeps the fin supple. If the door does freeze to the seal, a little warm water along the edge from inside, or simply waiting for the sun, frees it without pulling; dry the thawed spot afterwards so it does not simply refreeze.

What affects the quote
Adding a brush or foam seal to the sides as well as the stop
Some households want only the top and side stop replaced, while others add a brush or foam seal along the same run for a tighter fit against wind-driven snow. That extra material and the time to fit it are agreed before the old stop comes off.
Colour 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.
Fin 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.
What to have ready
- Have mice, leaves or water been getting in?
- Is the existing seal a flexible strip on a wood stop, or a one-piece vinyl moulding?
- Does the door rub or catch on the seal when it moves?
Garage Door Perimeter Weatherstrip: questions
QuestionsCan 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.
Should I choose a fin on the wood stop or a one-piece vinyl stop?
If the wood stop is sound, straight and not buried in paint, a new fin nailed to its face is the simpler choice and keeps the look of the trim. If the stop is cracked, soft or has been painted many times, a one-piece vinyl stop replaces it entirely, needs no paint and cannot rot. The technician checks the stop and recommends one or the other on site.
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.
