Same brick and frame house. Two huge garage door. 1x1 panels, about 25 across and twelve deep. They "float". Then move easily. My idea is that they are supposed to move. The doors are so big there's bound to be flexing and twisting. Contracor i work for had me caulk every one of them. His reasoning is that water can get into the cracks at teh bottom of the panels.
My take is that on every winow or garage door, that bottom profile is always dirty and worn because it takes the sun and dirt sits on it. I wouldn't caulk those.
What would you guys do in this situation?
