I would recommend Tim a million times!!! He finished everything on time and sent me photos of everything that was completed and his work was excellent. I gave him a budget and a time line. He NEVER wavered from either! I can't believe that he was my first experience with a contractor. He has spoiled it for everyone else. I highly recommend him!!!
