The gap under the door is a finger wide at one end and nothing at the other. The door itself looks straight, but the floor drops away toward the corner where the slab has settled, and drafts pour through the wedge.
What you have afterwards is a door that closes onto a single soft line of contact from jamb to jamb. Daylight under the door is much reduced, the draft across the floor eases, wind-blown leaves and snow are kept out more effectively, and the tighter gap makes the route in harder for mice. The opener has been reset so the door lands gently on the new strip instead of pressing it flat. You also leave knowing the seal's profile and size, which makes the next replacement a matter of one phone call, and a couple of simple habits for winter that keep the new seal from freezing to the floor.

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
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
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.
What shapes the quoteDownsview Door Specialists
FeesSame any hour
Plan on an hour or two for a straightforward replacement on a standard door, including the inspection and the opener reset. A retainer replacement, a hardened seal that has to come out in pieces, a wood door with a nail-on strip or the addition of a threshold seal each add time. The technician will give you a realistic window once the door has been looked at.
Sometimes. Many insulated doors have the seal channel moulded into a plastic cap that wraps the bottom rail, which takes a specific profile rather than a generic one. If that cap is cracked or the channel has opened, a screw-on aluminum retainer can be fitted over the rail so a standard T-style or bulb seal can be used from then on. Identifying the retainer at the first look settles which route applies.
Yes, and winter is when most people notice they need one. Vinyl is stiffer in the cold, so the technician keeps the new roll warm until it is fed and takes a little longer working it across the channels. A seal frozen to the floor is freed by hand first. The door is then closed onto the new strip and the opener reset exactly as in summer, and the garage is sealed for the rest of the season.
