Garage Door Perimeter Weatherstrip

The new door went in last year and looks perfect, but the old wooden stop and its tired seal were left in place. Along the top there is a gap you could slide a finger into, and the cold pours through it.

In plain words

The job follows a steady order. First the door is closed and the gaps are found from inside, by daylight and by feel. Then the door itself is checked for how it sits in the opening, since a seal only works against a door that is square to the frame. The jambs and header are inspected for rot and for how the old strip is fixed. The old material comes off, the surface is cleaned and repaired where needed, the header piece is fitted first and the sides after it, and the door is cycled several times to confirm nothing catches. You are shown the result with the lights off.

The call
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 · Hamilton

How the visit goes

Four long coiled garage-door springs on a concrete floor, three black with metal end cones and one rusty spring broken in two.
  1. Scene 1

    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.

  2. Scene 2

    Fastening that lasts through the seasons

    Fasteners are chosen for the weather they will live in: galvanized or stainless trim nails, exterior screws where the stop is heavy or the wood is hard, and weatherproof staples only for a light fin on sound wood. They are spaced evenly so the strip stays straight between them, and a nail set is used so the heads sit flush without crushing the vinyl. In cold weather the lengths are kept warm in the van until the moment they are fitted, because cold vinyl is brittle and splits at the ends. Fasteners near the end of each piece go in a little further back for the same reason.

  3. Scene 3

    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.

In the van

  • Tape measure, level and square
  • Utility knife and mitre saw
  • Flexible vinyl fin seal
  • Vinyl stop moulding with integral seal
  • Aluminum retainer and rubber insert

What shapes the quoteMount Nemo Door Specialists

Partial 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.
Trim, 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.
Corner detailing
Mitred corners on a one-piece stop, or fitting round an unusual trim profile, take more cutting and fitting than butted corners on a plain jamb.

Answers in plain language

How do I stop the seal freezing to the door in an ice storm?

Wipe the fin with a silicone spray or a silicone lubricant on a cloth in late autumn and once or twice through the winter. The film cuts the odds of meltwater bonding the fin to the cold door face, though a hard freeze can still catch it. Avoid oil-based products, which soften vinyl. If the door does freeze to the seal, let the sun or a little warm water free it, dry the spot afterwards, and avoid forcing the opener.

What is the difference between perimeter weatherstrip and the bottom seal?

The bottom seal is a rubber or vinyl strip fixed to the lower edge of the door itself and presses against the floor. Perimeter weatherstrip is fixed to the frame, running up both jambs and across the header, and the closed door presses against it from inside. They wear differently and are replaced separately, though it is common to renew both in one visit when each is showing its age.

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.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 61 in 100 homes · older homes
  • About 61% of homes in Hamilton were built in 1980 or earlier, according to the 2021 Census.Extension springs are common on older doors, and they should carry a safety cable through the middle so a broken spring is held rather than flung. Adding those cables is a small job the technician checks for and offers on any older door he services.
  • Single-detached houses make up about 56% of homes in Hamilton (2021 Census).A blend of housing means a blend of garages: spacious attached garages with full headroom on the detached lots, and tight tandem garages with little side room in the attached units. Openers, tracks and springs are all sized at the door rather than assumed from the street.
