- The call
- Dry leaves keep appearing in the same corner inside the garage, and this fall there were mouse droppings along the wall beside the door. When you look, the corner where the top and side strips meet is wide open.

The new door went in last year and looks perfect, but the old wooden stop and its tired seal were left in place. Along the top there is a gap you could slide a finger into, and the cold pours through it.
A perimeter seal is only as good as the door it meets, so a technician looks at the door before the seal. If one side shows daylight and the other is tight, the strip may be fine and the door may have drifted: worn rollers, a track bracket that has moved, a top section that bows away from the header. Setting that right first means the new fin can be positioned with the same light contact on every side. Where the door is already square, the seal is fitted straight to it. Either way the result is a door that closes against a continuous line of contact.

Scene 1
Gaps like to live where pieces meet. The technician looks at both top corners, where the header seal and the side seals should overlap so there is no square hole, and at both bottom corners, where the side seal should run right down to meet the bottom seal on the door. Mouse droppings, leaves and a small drift of snow in one corner are common finds and point to exactly which joint has opened. The bottom seal itself is noted; it is a separate part of the door, but if it is flattened or torn the household is told so both can be renewed in one visit if they wish.
Scene 2
When the old wood stop is cracked, rotten or buried in paint, it is replaced rather than covered. The one-piece stop, a rigid vinyl moulding with the flexible fin formed along one edge, is cut on a mitre saw to header and side lengths and fitted the same way, header first. It needs no paint, does not rot, and its fin and stop are one part, so the seal cannot peel away from the moulding. Corners are either mitred or the sides butted tight under the header with the fins overlapped. The result looks like fresh trim and works as a seal.
Scene 3
The simplest care is a glance four times a year. Close the door, switch off the lights and look along both sides and the header for daylight. Then step outside and check that no length has lifted, that the corners are still tucked together and that the fin is still soft when you press it with a thumb. Cracks, a hard grey surface or a piece that has shrunk back from the door are the early signs. Manufacturers suggest wiping the seal down with a damp cloth a few times a year, and that also lets you feel any change in it.

Wipe the fin with a silicone spray or a silicone lubricant on a cloth in late autumn and once or twice through the winter. The film cuts the odds of meltwater bonding the fin to the cold door face, though a hard freeze can still catch it. Avoid oil-based products, which soften vinyl. If the door does freeze to the seal, let the sun or a little warm water free it, dry the spot afterwards, and avoid forcing the opener.
The bottom seal is a rubber or vinyl strip fixed to the lower edge of the door itself and presses against the floor. Perimeter weatherstrip is fixed to the frame, running up both jambs and across the header, and the closed door presses against it from inside. They wear differently and are replaced separately, though it is common to renew both in one visit when each is showing its age.
It closes one of their favourite routes. Mice enter at the open corners where the header and side seals meet and along a fin that has shrunk back from the door, so a continuous, overlapped seal removes those gaps. It works alongside a sound bottom seal, a swept threshold and attention to any other openings in the garage wall, and a technician will point out any of those noticed during the visit.
