The seal slides into a retainer channel on the bottom rail. Once the rubber takes a permanent flat set, the gap it leaves is enough for water, draughts and mice.
Signs the seal is done
Daylight visible along the bottom with the door closed.
Water tracking into the garage in heavy rain.
Rodents or insects getting in — a gap of a quarter inch is enough for mice.
The rubber is hard, cracked or has taken a permanent flat set.
What climate does to seals
Sustained heat degrades rubber and vinyl fastest. In desert climates seals often need replacing every four to six years rather than the usual eight to ten.
Repeated freezing makes seals brittle and they tear when the door is opened against ice. In severe-freeze regions, a torn seal in February is routine.
Should you do this yourself?
Yes for the bottom seal on most doors — it slides out of a retainer channel and a new one slides in, for $25 to $60 in materials. Perimeter stop moulding is more fiddly but still within reach.
