Green_98 is spot on as to insulation and condensation. I had a garage built a few years back and due to the slope I needed to dig the back side into the ground. The walls are concrete, sealed with a masonry sealer, 9’ high and the back is dug 8’ in the ground. so the the back and half of the side walls are always colder in the spring thru fall. On humid days the wall sweats so much you would swear that wall is leaking. I have done the plastic sheet taped to the wall test and proved that the water was from condensation and not a leak coming thru the wall. The sweating gets worse when I open the doors. After doing research, the only way to stop the condensation is to equalize the wall temperature to the ambient temperature. Insulation would solve this. It’s on my list of things to do! I am also installing a dehumidifier to dry thing out when the garage is closed up.
Mike_B is also right when he said “build it bigger then what you think you need, there is never enough room!”
Mine is only 24‘ wide and due to the constraint‘s of my property, it was as big as I could squeeze in. Don’t get me wrong, I am thrilled that I have a place where I can store and work on my ‘52 Chevy 3100, but I am busting at the seams trying to find places to store all of the equipment required to work on these trucks. In this case, ”Size Does Matter”.
