I am tearing out the wood deck and replacing it with a lower maintenance cement patio. It will be the exact same demensions 12x16. Obviously, it won't be as high up as the deck but will be a foot off the ground. I've had several contractors give me estimates. The contractor I like (work within my budget/friendly/honest) will be coming over and will be bringing the proposal and then it will be time to sign the papers. He will be putting in a floating patio. It will not be attached to the house. Any questions that you can think of to ask when he comes back for a final Q&A session before signing the papers?
