I presently have a makeshift open lean to attached to my garage. I plan on ripping it down this summer and putting up a new, totally enclosed lean to attached to my garage. It is a cinder block garage. My question is on getting rid of the steam? How have others dealt with it. Some type of vent on the top against the garage, windows on the top near the garage wall or other ideas??? Really don't want to use a fan because of all the moisture.
