Trusted by Long Island homeowners
“Cristiano and his crew are reliable, professional, and efficient — true craftsmen who are talented, skilled, and incredibly precise. They replaced the base molding, crown molding, and trim throughout my home. Their attention to detail was exceptional, and the finished project exceeded my expectations. I would highly recommend That Guy Carpentry to anyone looking for high-quality craftsmanship.”Ann Marie VerolaTrim & molding · East Northport Google review
“We are greatly satisfied with our full kitchen renovation — great value for the craftsmanship. Cristian and his crew were reliable and kept the project on track. They didn’t just follow our blueprint; they partnered with us and offered creative ideas that made a massive difference. The final result is a gorgeous, high-quality kitchen that blew past our expectations.”Theo M.Kitchen renovation · Long Island Google review
“We had our bathroom renovated by That Guy Carpentry and I am so happy with the results. They truly listened to my vision but also gave great recommendations to pull everything together. They kept the area clean and tidied up each night, and they even finished earlier than the original timeline. I highly recommend them for your next project.”Tricia RBathroom renovation Google review
“Cristian redid our entire basement and turned it into a bedroom and playroom. He went above and beyond on timing and paid attention to every detail. He replaced the sheetrock, insulation, flooring, and lighting, and completely transformed the space. We are so happy with his work.”Reyna GalvinBasement renovation · Long Island Google review
