Garage Door Bottom Seal Replacement in New Wasaga Beach

After a spring rain there is a puddle inside the door that reaches the tires. The driveway slopes toward the garage, the slab has a low corner, and the flattened old seal is not making up the difference.

Garage Door Bottom Seal Replacement

In plain words

The bottom seal is one part of a weather line that runs all the way round the door. Vinyl-finned stop moulding seals the jambs and header, the section joints have their own tongue-and-groove or shiplap seals, and a threshold seal glued to the floor can meet the bottom strip where a slab slopes the wrong way. Bottom seal replacement addresses the piece that takes the most punishment, and while the technician is there the rest of the perimeter is looked over. Where the side or top strips are torn or shrunk, doing them in the same visit gives a garage sealed on all four edges rather than three.

Sound familiar?

One end of the bottom seal has slipped out of its channel and hangs down like a loose shoelace. Each time the door closes it folds under, each time it opens it flaps, and the gap beside it keeps growing.

How the visit goes

  1. The bottom section and its rail

    The seal can only be as straight as the edge it hangs from, so the bottom section gets a careful look. On a steel door the technician checks the bottom rail for rust where salt water has sat, dents from a bumper or a shovel, and any bow across the width. On a wood door the rail is checked for rot, cupping and the upturned corners of an old door that has dried unevenly. Fasteners for the retainer and the bottom brackets are checked for corrosion. A sound, straight rail lets a standard seal do its job; a damaged one is pointed out so you can decide on repair, a taller seal, or both.

  2. Taking the old seal out

    With the door secured, the ends of the old strip are freed from any caps or folds and the seal is drawn out of its channels from one end. A supple seal slides; a hardened one is coaxed with a flat blade and a little silicone, or cut into short lengths and removed a piece at a time. Old nails come out of a wood rail with a claw. The channels are then cleaned of grit, rust flakes, salt crust and any remnants of the previous strip with a wire brush and a scraper, because a clean channel is what lets the new seal feed through without tearing.

  3. The opener stays in step with the seal

    The opener was reset to the new seal height, and it will hold that setting until something changes. If the door begins to reverse just before the floor, stops short and leaves a gap, or lands with a thump, the down limit or force has drifted or the seal has taken a set, and a small adjustment puts it right. The reversing test with a 38 mm (1.5 in) solid object, or a 2x4 laid flat under the door, is worth repeating monthly and after any adjustment, as the industry checklist for homeowners describes. A door that closes gently and reverses on an obstruction is one whose seal and opener are working together.

What affects the quote

Same fees day, night or weekend

  1. 1Bottom section repairs

    A rusted, dented or bowed steel bottom rail, or a rotted wood rail, is pointed out and any repair or reinforcement offered as an option beside the seal work.

  2. 2Door out of level

    If one corner of the door hangs low because of cable or spring tension, levelling the door is separate work done before the seal goes in and is priced on its own.

  3. 3Material chosen

    Standard vinyl, cold-flexible rubber and silicone are priced differently. Where the door faces the weather, the technician explains what the step up buys in flexibility and working life.

Garage Door Bottom Seal Replacement: questions

Does a wood garage door use the same kind of seal?

Usually not. Wood doors most often carry a flat or angled strip of vinyl or rubber nailed directly to the bottom rail, rather than a profile that slides into a retainer. Replacement means removing the old strip and nails, checking the rail for soft or cupped wood, and fastening a new strip so its lip angles outward and meets the floor along the full width. A retainer can be added to a sound rail if you prefer a channel seal.

What is the difference between T-style, bead and bulb seals?

The names describe the edge that grips the retainer and the shape of the part that meets the floor. A T-style seal has T-shaped edges that slide into slotted channels along the bottom rail. A bead seal has round edges for the rounder channels found on many older steel doors. A bulb, or U-style, seal is a larger tube that compresses further and suits rough or dished floors. The retainer on your door decides which one fits.

What information helps when I book?

The width of the door and whether it is a single or double; what is getting in, whether light, drafts, water, snow or pests, and where along the door; whether the gap is even or worse at one end; the door material; and a photo of the end of the bottom section showing the retainer and seal. Mention if the seal has frozen to the floor or if the door has been reversing before it closes.
