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.
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.

Scene 1
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.
Scene 2
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.
Scene 3
A continuous seal removes the easy route mice and insects used along the floor. If rodents were part of the reason for the visit, a few habits finish the job: keep birdseed, pet food and grass seed in lidded bins, move firewood and cardboard away from the walls, and check the jamb seals at floor level, where a gap beside the door is as inviting as one under it. Seals with a stainless mesh embedded in the vinyl are available for garages that have had repeated trouble. A sealed bottom edge plus tidy corners keeps the garage a place where nothing wants to nest.

It closes the gap between the door and the slab so rain and meltwater meet a continuous barrier. Where the driveway slopes toward the garage, or the slab edge has dipped, the seal alone is working against gravity, and a threshold seal glued to the floor adds a lip that turns water back toward the drive. The technician looks at where the water comes from and recommends the combination that suits your threshold.
A seal can look intact and still have taken a permanent set, so the bulb no longer springs up to fill the gap. Otherwise the gap belongs to something else: a door hanging out of level, a bowed bottom section, a floor that has settled at one end, or an opener down limit set so the door stops short. The first look during the visit sorts these apart so the fix goes to the right place.
Many homeowners do, and a technician's value lies in the parts that go wrong: identifying the exact profile so the seal seats, freeing a strip that has fused into its channel, spotting a retainer or door-level problem behind the gap, and resetting the opener's limit and force so the door lands gently and still reverses on an obstruction. If you would rather have it measured, fitted and tested in one go, that is what the visit is for.
