Garage Door Bottom Seal Replacement in Cedarvale
After a spring rain there is a puddle inside the door that reaches the tires.
In plain words
In this climate the bottom seal lives a hard life. Meltwater from the car pools at the threshold and freezes the seal to the slab, and the next press of the remote tears it or drags it out of its channel. Road salt stiffens the vinyl and eats the aluminum retainer; deep cold turns a supple strip rigid. Replacement puts a cold-rated profile on a sound retainer, sized to meet the floor without over-compressing, and the technician shows how a wipe of silicone each autumn and a clear threshold keep the new strip from bonding to the ice. The door closes softly onto rubber again, not onto a frozen ridge.
How the visit goesEvery 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.

How the visit goes
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.
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.
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.

What affects the quote
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.
Perimeter seals done together
Jamb and header weatherstripping renewed in the same visit is quoted per length of stop moulding, and doing it alongside the bottom seal saves a second call-out.
Material 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.
What to have ready
- Is the door steel, wood, or insulated with a plastic bottom cap?
- Can you send a photo of the end of the bottom section showing the retainer?
- Is the old seal hard and cracked, torn, hanging loose, or missing?
Garage Door Bottom Seal Replacement: questions
QuestionsCan 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.
How do I look after the new seal?
Wipe it clean of salt and grit a few times a year, and give it a light coat of silicone spray each autumn so meltwater has nothing to bond to. Keep petroleum products and solvents away from it, since they soften vinyl. Clear ice and packed snow from the threshold before running the door in winter. Once a season, look under the closed door for daylight. That is the whole routine.
