The price he gave me does include materials. He also gave me his sq ft. price: $17.25/sq ft. for him to do everything. $16.00/sq ft. if I dig/pour the piers.
I talked to some neighbors this weekend. Apparently the person I had come out does very good work, but he is notoriously expensive. I think he is the type of person I would hire if I wanted custom made kitchen cabinets(for example).
This isn't going to our house forever. Probably at max., 5 years.
Having said that...I have explored doing it myself, with help of course. Another approach I am going to explore is having a carpenter attach it to the house and frame. I will do the rest.
I don't think I mentioned this before, but another part of this project is removing a casement window and adding a slider out to the new deck. In an ideal world I would like to have the carpenter do the door and the deck framing and I will do the rest.
