I hired a contractor to stain my deck. I requested that the underside also be stain to match the top. The contractor sent me a proposal listing all items that where to be treated. After he stated he was finished I questioned him on the underside. He claims that was not part of the proposal. I believed it was part of it and now there is a conflict in terminology. He used techincal terms when describing the deck. The terms have several meanings and our interpetations are different. I already paid him ahead of completion and now I'm seeking a full refund because he did not do the underside and the work he did do is not acceptable at all. He refuses to refund or fix any of the unacceptable areas or do the underside as we requested. Thank you!
