Garage Door Bottom Seal Replacement in Glen Huron

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

Not every gap under a garage door is the seal, so the service begins with finding out what the gap is. A strip of light the whole width usually means a seal that has flattened or hardened. A gap at one corner only points to a door hanging out of level or a slab that has settled there. A gap in the middle suggests a bowed bottom section or a crowned floor. Reading these before choosing a seal means the new strip is sized to fill the space that is really there, and any door or floor issue is named and dealt with rather than hidden behind a thicker bulb.

Sound familiar?

With the door closed and the lights off, a bright line of daylight runs along the floor from one side to the other. Leaves and grit have blown in under it and gathered in a neat drift against the back wall.

How the visit goes

Glen Huron

How the visit goes

  1. Which retainer and which profile

    Next the retainer along the bottom rail is identified. Most steel doors carry an aluminum extrusion with two channels that take the T-shaped or beaded edges of a U-shaped seal; some insulated doors have the channel moulded into a plastic bottom cap; older doors may have a single channel; wood doors often have a strip nailed straight to the rail. The technician measures the channel spacing and the T or bead size, checks the door width, and notes the height of the old strip. A seal chosen from these measurements slides in cleanly and holds, which is the difference between a replacement that lasts and one that works loose.

  2. Closing the door onto the new seal

    The clamps come off, the opener is reconnected, and the door is run closed under power while the technician watches the bottom edge meet the floor. The down limit is adjusted so the seal compresses gently along its full length without the section bowing, and the force setting is checked so the door settles onto the new, taller strip without reversing. From inside with the lights off, the floor line is checked again for daylight. The reversing test with a 38 mm (1.5 in) solid object, or a 2x4 laid flat under the door, and the photo-eye test finish the visit, and you are shown the door closing before the ladder is packed.

  3. A clear threshold through winter

    The seal closes onto whatever is on the floor, so the threshold deserves a moment when you clear the driveway. Push packed snow and the ridge of ice that forms where the door meets the slab away from the opening before running the door, and sweep salt piles and grit clear of the line so they are not ground into the strip. Park a little further in, if the garage allows, so drips from the car fall on the floor rather than at the seal. These are the same habits that protect the bottom brackets and cables in the corners.

What affects the quote

Same fees day, night or weekend

  1. 1Condition 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.

  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. 3Threshold seal added

    Where a floor threshold is recommended, its length, its type, whether rubber or aluminum-backed, the adhesive and the floor preparation before it is laid appear as a line of their own.

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.
