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

Winter is what wears a perimeter seal out here. Sun and cold cycles harden the vinyl until it cracks, freezing rain glues the fin to the door so the opener tears it, and salty slush sits against the bottom of the jambs and rots the wood the strip is nailed to. One visit deals with all of that: soft wood at the base of the jamb is cut out and replaced, fresh seal is fitted in continuous lengths with the corners overlapped, and the fin is wiped with silicone so ice does not bond to it. The garage stays drier and calmer through the next freeze-thaw season.

Sound familiar?

The bedroom over the garage is always the cold room, and standing in the garage you can feel why: a steady draft along the door edges that moves the cobwebs on the wall. The seal around the opening has flattened to nothing.

How the visit goes

How the visit goes

  1. 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.

  2. 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.

  3. If the door changes, the seal is re-checked

    The seal was set against the door as it sits today. If the door is later adjusted, has its springs or rollers replaced, or is swapped for a new one, the contact can change: a door that now sits a few millimetres further out presses the fin harder, and one that sits further in leaves a gap. After any such work, do the daylight test again and ask the technician doing that job to check the perimeter seal while they are there. Re-setting a length is a small task and keeps the two parts of the system working together.

What affects the quote

Same fees day, night or weekend

  1. 1Condition of the jambs

    Soft or rotten wood at the base of a jamb is cut out and spliced with new lumber or PVC trim before the seal goes on, and that repair is quoted as its own item.

  2. 2Jamb material

    Wood jambs take nails; steel or aluminum-clad jambs need screws and sometimes a backing piece, and masonry openings need a different fixing altogether, each with its own time and hardware.

  3. 3Removing the old stop and paint build-up

    Lifting a wood stop that has been painted for decades, scraping old adhesive and knocking down paint ridges takes longer than pulling a loose fin, and the time shows in the quote.

Garage Door Perimeter Weatherstrip: questions

How long does the visit take?

A straightforward fin replacement on a single door is often a matter of an hour or two once the technician is set up; a double door with a one-piece stop takes longer, and any jamb repair adds to it. Most of the time goes into checking the door, preparing the surface and setting the contact carefully, since those are what make the seal last. You are given a sense of the timing when the work is confirmed.

Can you replace just one side or only the top piece?

Yes, a single damaged length can be replaced when the rest is sound and still soft; the new piece is matched to the existing profile and colour and its corner is overlapped with the neighbouring fin. When the whole set is the same age and the others are hardening too, replacing all three at once gives an even seal and saves a second visit, and the technician will say which applies.

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.
