Hi Carly. Yes, the seals can shrink some in extreme cold. What can be done to prevent shrinking in very cold climates is to secure the ends and center section with a Tapcon or similar concrete anchor. They are available in either a hex head or screw. Here is an example.

Hello Ronnie. What worked for Allen was to install garage door seals on the exterior side moldings of the garage door. The sides of the seals go right to the ground and form a seal against the door when it is closed. There are many examples on Youtube that show how they work and how to install them.

Hi Shea, I have a similar, if not the same issue as Allen. I have a rollup door that does not seal at the corners. The Jams were cut short and bevelled to prevent rot, which creates a super highway for insects to enter the garage. I will need to implement (cut and shape) some custom solution, but so far I can think of nothing that has anything but a “rigged” and unprofessional-like appearance. If you helped Allen, I would like to know your solution. Thank you!

Hi Art. If you live in a milder winter climate that does not experience snow and freeze thaw cycles, then you can let the apron be as is. However, if you do live in a harsher winter climate, then we would recommend sealing the apron with a good penetrating sealer.
