Garage Door Perimeter Weatherstrip in Midland

A length of weatherstrip along the right jamb has pulled away, nails and all, and it slaps against the trim every time the wind picks up. The wood behind it is dark and soft where it meets the floor.

Garage Door Perimeter Weatherstrip

In plain words

Around a garage door there are three seals: one on the bottom edge of the door, and two running up the sides and across the top of the opening. Those last two are the perimeter weatherstrip. They are fixed to the stop moulding on the jambs and header, and their flexible fin rests against the door face when it is closed, closing the gap between door and frame. Replacing them means fitting new lengths that meet the door evenly, cutting down how much wind, driven snow, dust, leaves and small animals get through. The bottom seal is handled as its own job, but the two are often done together.

Sound familiar?

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.

How the visit goes

  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. Making the jamb sound

    Where probing found soft wood, it is dealt with before the seal. Rot at the base of the jamb is cut back to solid material and a matching piece of lumber or PVC trim is spliced in, fixed and primed. Minor soft spots are hardened with an epoxy consolidant and filled. Fasteners that will hold the new stop are then going into wood that grips them, which is what keeps the strip tight through years of the door pressing on it. Where the jamb is clad, the technician finds the solid framing behind the cladding and fastens through to it rather than into the thin skin.

  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. 2Corner 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.

  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

Why is there daylight on one side but not the other?

It can be either. Worn rollers, a track bracket that has shifted or a top section that bows can move the door face toward one jamb and away from the other, and a seal that is damaged, shrunk, the wrong size or set slightly off the door face shows the same way. The technician checks both the door's alignment and the seal itself, corrects what is out of true, then fits the new seal to a door that closes evenly.

Do you adjust the door as part of the seal work?

Small corrections, yes. If a track bracket needs re-setting or the door needs to come plumb so the fin can meet it evenly, that is done so the new seal is fitted to a door that sits properly. Larger work, such as replacing rollers or a bowed section, is explained and offered as its own job so you can decide on it separately.

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.
