Garage Door Bottom Seal Replacement

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.

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.

The call
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.

How the visit goes

Illustrative garage doors scene
  1. Scene 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. 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

    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.

  • Track clamps
  • Threshold seal and adhesive
  • Silicone spray lubricant
  • Bulb or U-style bottom seal
  • Nail-on vinyl strip for wood doors

What shapes the quoteInnisfil Garage Door Co.

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.
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.
Door 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.

Things people wonder

What are bottom seals made of, and which suits cold weather?

Most are vinyl, which resists sun and moisture well but stiffens in deep cold. Rubber compounds stay flexible at low temperatures and follow an uneven floor closely, though they can harden after many years of sun. Silicone stays supple in heat and cold and resists cracking, at a higher cost. For a door that faces the weather, a rubber or silicone profile is usually the sounder long-term choice.

Can mice get past a garage door bottom seal?

A worn, hardened or chewed seal is one of their favourite routes, and even a small gap at a corner is enough. A fresh, continuous seal sized to the floor removes that route. For a garage with repeated trouble, seals with a stainless mesh embedded in the vinyl are available and resist chewing. Keeping the jamb seals sound at floor level matters just as much, since a gap beside the door serves them equally well.

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.

  • 35 in 100 homes · mixed ages
  • About 35% of homes in Innisfil were built in 1980 or earlier, according to the 2021 Census.In areas with a spread of building periods, garage doors fail for different reasons on the same street: worn pulleys and stretched cables on the older doors, cycle-limit springs and tired opener gears on the newer ones. Knowing which pattern applies shortens the diagnosis.
  • Single-detached houses make up about 90% of homes in Innisfil (2021 Census).Detached houses often have a room over the garage, a bedroom or an office, which makes the garage door part of the heated envelope. An insulated door, snug weatherstrip and a fresh bottom seal keep that room comfortable and the furnace from working overtime in winter.
