Garage Door Perimeter Weatherstrip in Newton Brook

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

A perimeter seal is only as good as the door it meets, so a technician looks at the door before the seal. If one side shows daylight and the other is tight, the strip may be fine and the door may have drifted: worn rollers, a track bracket that has moved, a top section that bows away from the header. Setting that right first means the new fin can be positioned with the same light contact on every side. Where the door is already square, the seal is fitted straight to it. Either way the result is a door that closes against a continuous line of contact.

Sound familiar?

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.

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. Cycling the door and sealing the joints

    Once all three lengths are on, the door is run through several full cycles by hand and then with the opener, while the technician watches each fin for catching, folding or rubbing and listens for a squeal. The daylight test is repeated from inside with the lights off. Any joint between the new stop and the trim or brickmould where water could get behind is caulked with an exterior sealant, and the fin is wiped with a silicone spray to cut the odds of ice bonding it to the door. The old material is bagged and removed, and the household is walked round the finished opening.

  3. A look round each season

    The simplest care is a glance four times a year. Close the door, switch off the lights and look along both sides and the header for daylight. Then step outside and check that no length has lifted, that the corners are still tucked together and that the fin is still soft when you press it with a thumb. Cracks, a hard grey surface or a piece that has shrunk back from the door are the early signs. Manufacturers suggest wiping the seal down with a damp cloth a few times a year, and that also lets you feel any change in it.

What affects the quote

Same fees day, night or weekend

  1. 1Working 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.

  2. 2Fin 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.

  3. 3Colour 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.

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.
