Garage Door Bottom Seal Replacement

The strip under the door has gone as hard as a hose left out for ten summers. Press it and it does not give; bend it and it cracks.

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.

The call
Every mild afternoon the snow melts off the car, runs to the door, and by morning the rubber strip along the bottom is frozen to the concrete. Last week the opener lifted the door and left half the seal on the floor.

Garage Door Bottom Seal Replacement · Niagara Falls

How the visit goes

Two long steel winding bars inserted into the cone of a black torsion spring lying on a concrete floor.
  1. Scene 1

    How the opener meets the floor

    Before the old seal comes off, the technician watches the door close under power. Where the door stops, how firmly it lands, and whether the bottom section flexes as it settles all show how the down limit and force are set. A door that stops short leaves a gap regardless of the seal; one set to press hard flattens a new seal in a season and can bow the section. The current settings are noted so they can be reset once the new, taller strip is in place, and the photo eyes and reversing behaviour are checked at the same time so the finished door is tested against a known starting point.

  2. Scene 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. Scene 3

    A door that meets the floor in one line

    The first thing you notice is the absence of daylight. With the door closed and the lights off, the floor line is dark from one jamb to the other, and the draft that used to move across the floor is much reduced. The door lands softly, because the opener now stops when the seal is gently compressed rather than driving the section into the concrete. Leaves, grit and drifting snow are kept out far more often. If you crouch and look, the new bulb sits evenly along the slab, filling the low corner the old strip used to hover above.

In the van

  • Bulb or U-style bottom seal
  • Aluminum bottom seal retainer
  • Threshold seal and adhesive
  • Silicone spray lubricant
  • Bead-style bottom seal

What shapes the quoteChippawa Garage Door Pros

Number of doors
Two single doors are two seals, two inspections and two opener resets. The travel is shared, so doing both in one visit costs less than two separate calls.
Condition of the old seal
A supple strip slides out in a minute. One that has hardened and seized in its channel, or been torn and frozen into the corners, has to come out in pieces, which takes longer.
Rodent-resistant seal
A profile with embedded stainless mesh for a garage that has had repeated chewing costs more per length than plain vinyl and is offered where the history calls for it.

Straight talk

Why is the gap much bigger at one corner?

Two causes are common. The door may be hanging out of level because a lift cable has stretched, a drum has crept on its shaft or spring tension is uneven, which drops one corner. Or the slab may have settled or heaved at that end so the floor falls away. The technician checks both before choosing a seal, since a level door and the right seal height together close a wedge-shaped gap.

How do I know which size and type my door takes?

Look at the end of the bottom section for the metal or plastic strip that holds the seal. Count the channels, note whether they are slotted or rounded, and measure the distance between them and the width of the door. A photo of the end of the retainer and one of the seal's cross-section is usually enough for the technician to identify the profile before the visit and bring the right roll.

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.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 61 in 100 homes · older homes
  • About 61% of homes in Niagara Falls were built in 1980 or earlier, according to the 2021 Census.Older garages are frequently used as workshops or storage as much as parking, which means the door opens many times a day and collects dust on the sensors. Sealed rollers, protected photo-eyes and a tune-up schedule suit that pattern well.
  • Single-detached houses make up about 66% of homes in Niagara Falls (2021 Census).Detached houses commonly have attached two-car garages with a wide double door, which is a heavy door on a pair of torsion springs. Spring and cable work on these doors is done as a matched set so the door lifts level and the opener carries only its intended load.
