The contractor was knowledgeable about all aspects of my remodel and gave me ideas that worked with my project. Project was completed in a short time-frame and I got my finished family room, kitchen, dining, living room and office completely tiled and painted with new trim and baseboards. He retiled my fireplace and two small bathrooms. Great job! Everyone loves my home:)
