Garage Door Perimeter Weatherstrip in Mount Pleasant

Dry leaves keep appearing in the same corner inside the garage, and this fall there were mouse droppings along the wall beside the door. When you look, the corner where the top and side strips meet is wide open.

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?

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.

How the visit goes

Mount Pleasant

How the visit goes

  1. What has been getting in, and what the garage is for

    A short conversation shapes the rest of the visit. Is the garage attached and heated, or a detached shell? Has snow, water, leaves or an animal been coming in, and where? Is the door used several times a day or once a week? Was the door itself replaced or adjusted recently? A heated garage under a bedroom justifies a full one-piece stop and careful corners; a detached garage used for storage may want a straightforward fin replacement. Knowing what the household has noticed also tells the technician which side to test first and whether a section of jamb has been wet for a long time.

  2. Replacing the wood stop with a one-piece vinyl stop

    When the old wood stop is cracked, rotten or buried in paint, it is replaced rather than covered. The one-piece stop, a rigid vinyl moulding with the flexible fin formed along one edge, is cut on a mitre saw to header and side lengths and fitted the same way, header first. It needs no paint, does not rot, and its fin and stop are one part, so the seal cannot peel away from the moulding. Corners are either mitred or the sides butted tight under the header with the fins overlapped. The result looks like fresh trim and works as a seal.

  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. 1Commercial or oversized openings

    Wider and taller commercial doors often carry an aluminum retainer with a rubber insert or a brush seal, and the material and fitting time differ from a residential vinyl seal.

  2. 2Working height and access

    A tall header, a sloped driveway that makes a ladder awkward, shrubs against the jambs or cars and storage close to the door all affect how long the work takes.

  3. 3Trim, 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.

Garage Door Perimeter Weatherstrip: questions

What are perimeter seals made of?

Most residential seals are flexible vinyl or a rubber compound formed into a fin that bends against the door. They come either as a flexible strip that is nailed to a wood stop or moulded onto a rigid vinyl stop as one piece. Commercial doors sometimes use an aluminum retainer holding a replaceable rubber insert, or a brush seal. Manufacturers make them to flex thousands of times as the door operates.

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.

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.
