First let me say hello. This is my first post in PWR. I have had my window cleaning buisness going for about 7 months and things have been going great. I have been thinking about adding pressure washing to the buisness but don’t know much about it and have not had the cash flow to buy the equipment. So here is my question. The manager at one of the Starbucks I clean windows at asked me if I would give him an estimate on pressure washing his drive thrue. He is a friend and really likes the work I do on the windows and trust me to provide good service. I told him to give me some time and I would get back to him. I know that I can rent a machine since I cant afford one yet, but like I said I really don’t know much about pressure washing. Is this something I should attempt? If so, any advice on where to start would be great.
