"I called five different companies from the Angi list before finding Colonna Consulting. When I called and I explained my situation to Nick (the owner), I immediately knew he was the one. Despite his tight schedule, he managed to fit me in on the same day. We hired Colonna and Nick to inspect our residential structural foundation. Nick responded promptly to my requests and explained everything clearly during the inspection. He completed the report within the same day. Working with him was a pleasure, and his professionalism made the process smooth and stress-free. Thank you very much Nick, for your fast response."

"Julian delivered exceptional engineering analysis and design work for my residential gut rehab. He was consistently available, willing to help, and brought strong technical expertise to every discussion. His vision for an open‑wall layout led to the installation of a structural beam that completely transformed the home’s flow and created a true open‑concept space we never thought possible. He worked efficiently, communicated clearly, and carried himself with total professionalism. I highly recommend him to anyone looking to upgrade or reimagine their living space."

"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"

"Excellent service; very professional. Since the waterproofing was done, have not had any problems with water in our basement."

"I was long over due on doing a addition/ remodeling project on my house. I had Victor come out and I went over what my plans were and what I had envisioned. He was quick to offer solutions that met the cities guidelines, which meant part of my addition would be 2 stories, to allow room for my master suite. They prepared the plans worked out all the details with me. The scope of our project was; adding a master suite, enlarging the family room, kitchen remodel, powder room remodel, and some other misc. work. I was pleased with every aspect of there work, from customer service to the quality of the work preformed. One thing I was really impressed by is the attention to details. Victor would spend so much time talking to me about little design elements, how to position the lights, where to put switches, all things which I thought were pointless at the time. But now I realize all those little things really do add up to make a great finished product. All around it was a pleasure working with Build Now NYC"

"Fernando and Francisco were fantastic! Professional, punctual and reasonably priced. They did a beautiful job rebuilding some stone pillars for us and replacing damaged fencing. Also power washing. Could not have been more satisfied with the work."
