"I chose Carico Drywall because of his attention to detail, the fact he came out to give me an estimate, and the fact that he uses Union Drywall Installers. He was my 3rd bid in my buildout for my garage, and he was the highest bid by far. But the fact that he came to my house, met with me, explained and asked good genuine questions proved to me that he was the correct person to do the job. My garage is 1500sqft (30 ft deep , 50 ft wide) ceiling height is 18ft. At the peak, its roughly 22ft. I used R21 batting in the walls and 6 to 7 inches of open cell spray foam in the ceiling. The shop was drywalled with 5/16 inch drywall, no real need for anything thicker since the insulation keeps most sound dampened. I didnt tackle the drywall, because I felt like that would have taken me forever. Would i recommend Carico to do more projects? Yes I would."

"The Dowell family arrived promptly and began extensive repair of plaster walls and ceilings. They were professional, flexible and did extra work without increasing the original bid. They were clean and finished earlier than expected. They repaired problem areas where drywall and plaster joined. They repaired large holes in garage. The quality of the work is exceptional and the price was the fairest, least inflated that we received. We had to wait 3 weeks for start day but it was well worth it. They noticed so much plaster damage that we did not see and restored the integrity of the walls of our childhood home in preparation for selling. Thank you for the beautiful work."

"The guys were great from start to finish the communication and the great estimate from Pete and his son I didn’t need a 2nd opinion from anyone else. I will definitely hire S&S again for other projects plus I referred them to others that desperately needed an honest company BBB accredited plus great references. I give them 5 stars plus 👍"
