- The call
- After a windy night there is a fine ridge of snow on the garage floor along one side of the door, and another across the top step. The door was shut the whole time; the snow came in around it.

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.
For an attached garage the perimeter seal does more than keep leaves out. The garage is a buffer between the weather and the house, and drafts around the door cool the wall it shares with the kitchen and the floor of the room above it. Snow blown in melts and refreezes on the slab, and mice follow the warm air in at open corners. A well-fitted side and header seal closes those paths and eases the job of the weatherstripped door between garage and house, though the garage's warmth also depends on the door's own seal, the ceiling and the heating. It is a worthwhile comfort improvement for the house.

Scene 1
A perimeter seal can only follow a door that sits where the frame expects it, so the door is checked before any strip is ordered or cut. Each edge is checked for plumb, the gap to both jambs is compared, and the top section is watched as it meets the header to see whether it bows away or leans in. Rollers, hinges and the spacing of the vertical tracks are looked at because any of them can shift the door face toward one jamb and away from the other. Small corrections, such as re-setting a track bracket, are noted so the new seal is fitted to a door that closes square and stays that way.
Scene 2
With the door closed, the header length is cut to the full width of the opening and lifted into place, a two-person job on a double door. It is positioned so its fin lies against the top section with a slight, even deflection along the whole width, then fastened from the centre outward with galvanized or stainless nails or exterior screws at regular spacing, which keeps the length straight rather than letting it wander. The ends are left to receive the side pieces beneath them. Fitting the header first means both sides are cut to meet it exactly, and the corners close properly.
Scene 3
With the header and side fins overlapped, the small square holes that mice and wasps used are gone. Keep them that way by checking the four corners each autumn, when animals are looking for warmth, and pressing any lifted corner back into place. The point where the side seal meets the bottom seal on the door is worth a look too, since the bottom seal wears on its own schedule. A clear threshold, with leaves swept away from the door, removes the shelter pests use to work at a corner. Sealing the perimeter is one of the simpler parts of keeping a garage pest-free.
What shapes the quoteErin Mills Garage Door Experts
FeesSame any hour
A little, though it is not the main reason to do it. A fresh bottom seal cushions the door's contact with the floor, and snug side and top seals stop the panel rattling against loose or worn stops. Most of the noise people notice from a garage door comes from rollers, hinges and the opener chain or belt rather than the seals, so a technician checking the weatherstrip will usually point out those parts too if they are the louder culprit.
Move the car out of the garage or well back from the door, and clear anything stored against the jambs inside and any bins, planters or snow piled against them outside. Leave the door closed so the gaps can be seen as they are. If you have noticed where the daylight, drafts or snow come in, or where the mice appear, be ready to point it out.
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.
