Savings on Maintenance Costs. A masonry building requires a minimum of maintenance primarily because masonry does not rust, shatter, warp, dent, buckle or rot, and there is no need for cleaning or repainting. Consideration of the vulnerability to damage of building walls is also important. Whether a careless fork lift operator or strong winds with hail hits the wall, or a heavy object is propped against the wall, masonry can handle the abuse.
