Garage Door Bottom Seal Replacement in Buena Vista Park
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.
How the visit goesThe garage doubles as a workshop, and with the heater running the floor near the door stays cold and the draft finds your ankles at the bench. When the wind is up you can feel the air moving under the door.

How the visit goes
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.
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.
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
1Retainer 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.
2Number 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.
3Perimeter 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.
Garage Door Bottom Seal Replacement: questions
Should the side and top weatherstripping be replaced at the same time?
It is worth having them looked at while the technician is there. The vinyl fin on the stop moulding around the jambs and header shrinks, tears and hardens on the same schedule as the bottom seal, and a draft that survives a new bottom seal usually comes from the sides. Doing the perimeter in the same visit saves a return trip and leaves the door sealed on all four edges.
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.
Will I need a new retainer as well as a seal?
Only if the existing one is damaged, and most are reused. A retainer that is straight, tight to the rail and free of heavy corrosion stays. One that has been kinked by a bumper or shovel, spread open so the seal slips out, or eaten by salt is replaced with a matching aluminum extrusion so the new seal seats properly. The inspection at the start of the visit settles which applies.
