- The call
- The 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.

There are mouse droppings along the wall behind the recycling bins, and at one bottom corner of the door the vinyl has a neat chewed notch the width of a thumb. Something has found its way in for the winter.
A seal visit runs in a set order. With the door closed, the technician looks for daylight along the floor line and notes whether the gap is even or concentrated at one point. The door is checked for level and the bottom section for straightness, then the retainer is identified and measured. The opener is disconnected and the door secured before the old strip comes out and the channels are cleaned. A new seal, cut a little long, is fed into the channels and trimmed. Finally the door is closed onto the new seal, the opener's limits are reset, and the reversing test is run before the tools go away.

Garage Door Bottom Seal Replacement · Vaughan

Scene 1
A gap that is wider at one corner is often the door rather than the seal. The technician checks that the door sits square in the opening by comparing the bottom edge to the floor at both ends and looking at how each lift cable wraps its drum. A stretched cable, a drum that has crept on its shaft or uneven spring tension drops one corner a centimetre or two, and setting the door level is what closes that wedge. If the door is out of level, the adjustment is explained as its own item and done first, and the seal is then sized to the gap that remains. Getting the order right saves fitting a seal twice.
Scene 2
Where the slab slopes toward the garage or has a dished edge, a threshold seal glued to the floor follows the existing contour and gives the bottom strip a raised, consistent edge to meet, rather than levelling the floor itself. The floor line is marked with the door closed, the concrete is swept and cleaned for the adhesive, and the threshold is dry-fitted and trimmed against each jamb. Adhesive is laid along the underside, the threshold pressed down, and the door lowered onto it while it sets. The result is a small raised lip on the outside that turns water back to the driveway and a bottom seal that lands on a consistent edge along its length.
Scene 3
With the bottom sealed, any remaining draft points to the perimeter: the vinyl fin on the stop moulding at the jambs and header, and the joints between sections. These were looked over during the visit and anything torn, shrunk or missing was pointed out. Replacing perimeter stripping is straightforward work that can be planned for a mild day. Together with a sound bottom seal and, where the floor calls for it, a threshold, the garage gains a stronger barrier against wind, water and cold on all four edges, and an attached garage can stay closer to the temperature of the house.

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.
Usually not. Wood doors most often carry a flat or angled strip of vinyl or rubber nailed directly to the bottom rail, rather than a profile that slides into a retainer. Replacement means removing the old strip and nails, checking the rail for soft or cupped wood, and fastening a new strip so its lip angles outward and meets the floor along the full width. A retainer can be added to a sound rail if you prefer a channel seal.
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.
