Garage Door Bottom Seal Replacement

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.

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.

How the visit goes

  1. Scene 1

    Retainer condition and fasteners

    The aluminum or plastic retainer that grips the seal is inspected along its full length. The technician looks for kinks where something struck it, channels that have been spread open, corrosion where salt has sat, and screws that have rusted or pulled loose from the rail. A retainer that is straight and tight is reused; one that is damaged is measured for a matching replacement so both channels line up with the new seal. On doors where the retainer is part of a plastic bottom cap, a cracked cap is noted and a screw-on aluminum retainer is offered as the practical repair.

  2. Scene 2

    Feeding the seal into the retainer

    Both edges of the new seal are started into their channels together at one end of the door. A spray of soapy water or silicone on the edges lets the strip glide, and the technician works it across in stages, pulling gently from the front end and feeding from the other so the seal is never stretched, since a stretched seal shrinks back and leaves a gap later. Once it is across, the bulb is checked to hang evenly with no twists. The ends are trimmed flush with the door and folded up into the channel or capped, so water running along the seal drains out rather than into the section.

  3. Scene 3

    What to look for each season

    Once a season, close the door, turn off the lights and look along the floor. You are checking for a line of daylight, a corner where the seal hovers, an end that has slipped from its channel, and cracks along the fold of the bulb. Run a hand along the strip for stiff or brittle patches. Then watch the door close under power once and notice how it lands. A change in any of these is worth a call while the fix is a seal or an adjustment rather than a torn strip dragged through a winter. The check takes less time than reading this paragraph.

What shapes the quoteBroughdale Garage Door Specialists

Retainer replacement
If the aluminum or plastic retainer is bent, spread open or corroded, a new extrusion, fasteners and the time to fit it straight along the rail are added as their own line.
Bottom 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.
Door width
A single door takes a shorter length of seal than a double, and the widest doors need more time to feed the strip evenly across. The quote starts from the width measured on the day.

Homeowners ask

What happens during the visit?

The technician maps the gap with the door closed, checks the door is level and the bottom section straight, and identifies the retainer and profile. The opener is disconnected and the door clamped at working height. The old seal comes out, the channels are cleaned, a new seal is cut and fed in, and any retainer work is done. The door is then closed under power, the opener reset, and the reversing and photo-eye tests run.

How long does a bottom seal last?

Several years is typical, with the range set by exposure. A door facing south or west, a threshold that is wet and salted all winter, and a seal that freezes to the floor a few times a season all shorten the life. A shaded door on a dry slab with a wipe of silicone each autumn can go much longer. The condition of the strip, rather than its age, is what to watch.

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.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 42 in 100 homes · mixed ages
  • About 42% of homes in Middlesex Centre were built in 1980 or earlier, according to the 2021 Census.Where housing is mixed, so are garage sizes: single doors on older lots, double doors on infill and newer builds. Spring pairs, cable lengths and opener strength are all sized to the actual door, and we carry the range to cover whichever door is in front of us.
  • Single-detached houses make up about 91% of homes in Middlesex Centre (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.
