I was asked to bid on cleaning 25 apartment buildings. I have a company I do work for every year. However I usually only do the breezeways, stairwells, and concrete. These folks want all that, as well as all the vinyl on the outside. First, there are about 5 different styles of buildings. The ones I'm concerned with are the 3 level ones. My first concern is the height. I don't think I can reach the top with my 24foot extension wand. There are 2 that even sit on a hill. So may have to rent a lift to do some of them. That's one cost I have to factor in.(if you know the going rate please include). The big ones have 2 sets of breezeways. I will include pictures of the largest ones. There are about 11 of those. I can figure the others from that. I realize this is out of my league and will probably take on a partner. As to not take forever to complete. I hope the pics are attached. I had a difficult time.
