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
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
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
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.

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.
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.
Three, and they can be combined. A taller bulb-style seal compresses more and follows a modest dip or crown. A threshold seal fixed to the floor follows the slab's existing contour and gives the door a raised, consistent line to land on where it is dished or sloped. And where the floor has heaved or broken up badly, grinding or patching the concrete is a separate job that makes any seal perform better. The gap map from the first look shows which applies.
