EXCELLENT Based on 3 reviews JoBeth Borsello2025-04-26Trustindex verifies that the original source of the review is Google. Chris Duffy designed and built our deck for us at the shore. His attention to details and communication on the project was profound. We will definitely hire him again for other projects and recommend him to our family and friends. Diane Paccione Rizzo2025-04-26Trustindex verifies that the original source of the review is Google. Chris and his team did a great job building a brand new deck. Provided a 3D replica/ photo to insure the design was my vision. Coast Carpentry provide various samples with prices. Seamless process from inception to building the deck. No surprises highly recommend for any carpentry job. Lou Scala2025-04-26Trustindex verifies that the original source of the review is Google. Chris just completely rebuilt my deck from the ground up. Not only does the deck look beautiful it is constructed to last forever. He used the both best materials to ensure the deck withstand's the elements of the house's location,which is 2 blocks from the ocean. To sum it up , the deck is built perfectly, looks beautiful and will last a lifetime. I highly recommend Coast Carpentry! Chris was also a delight to deal with. Sincerely, Lou Scala 😀
