Garage Door Perimeter Weatherstrip in Willowdale

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.

How the visit goes

  1. Probing the jambs and header

    The strip is only as secure as the wood behind it, so the jambs are probed with an awl along their length and especially the lowest part, where slush and salt sit all winter. Soft, dark or crumbling wood is marked for repair. The header is checked for sag and for gaps opening between it and the top section. Where the jambs are clad in aluminum or vinyl, the technician looks for what the cladding hides and for where the seal can be fastened through to solid material. This step often adds a splice of new lumber or PVC trim to the job, and it is what makes the new seal stay put.

  2. The header piece goes on first

    With the door closed, the header length is cut to the full width of the opening and lifted into place, a two-person job on a double door. It is positioned so its fin lies against the top section with a slight, even deflection along the whole width, then fastened from the centre outward with galvanized or stainless nails or exterior screws at regular spacing, which keeps the length straight rather than letting it wander. The ends are left to receive the side pieces beneath them. Fitting the header first means both sides are cut to meet it exactly, and the corners close properly.

  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. 1Fin 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.

  2. 2Colour 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.

  3. 3Jamb 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.

Garage Door Perimeter Weatherstrip: questions

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.

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 should I do before the technician arrives?

Move the car out of the garage or well back from the door, and clear anything stored against the jambs inside and any bins, planters or snow piled against them outside. Leave the door closed so the gaps can be seen as they are. If you have noticed where the daylight, drafts or snow come in, or where the mice appear, be ready to point it out.
