"Closet expansion!! I don’t normally do reviews, but I had to share my experience with this company. OUTSTANDING WORK! Dan and Joe demolished 2 walls and rebuilt them in one day including sheet rock. From there Kyle took over the project spackling, painting and hanging the barn door. All of their work was super neat, clean, and meticulous. Frank was my salesman, and he was great. Price was very fair. John’s communication was constant and always appreciated. I also appreciated that he walked the job before and after to make sure I was happy with what I was getting. Better than any other contractor I’ve used in the past. Ten out of ten, a must hire company. "

Lou is reliable and courteous, which makes him my "go to" guy when recommending his services to my clients."

"After years of working with various contractors on major home improvements, we finally found our dream team with Duane Mainardi Builders! From the moment we reached out, Duane and his crew impressed us with their honesty and clear communication. Duane was always available throughout the project, and Keith, the site foreman, was simply incredible. He was onsite every step of the way and made the entire experience smooth and enjoyable. When we asked for changes after work had started, they welcomed every request with a genuine commitment to getting it just right. The siding crew was professional, skilled, and worked tirelessly. What we anticipated to be a four day job was impressively completed in just two and a half days. The final result? Gorgeous vinyl siding that has completely transformed our home?s look. We wholeheartedly recommend Duane Mainardi Builders if you want high quality siding done right by a team that truly stands behind their work. Michael and Vicki Sneed"
