"NexGen contacted us promptly (the next day) to schedule an estimate. They were able to come out on a Saturday to take a look, and gave us options and prices on the spot. The work was completed in one day. They cleaned the work site, did not damage any property, and were very professional and polite while they were onsite. They also complete slate roofing repairs, and we plan on hiring them in the future!"

"This company provides excellent customer service! We bought a home in 2016 that included a pool house awning installed by Sondrini Enterprises in 2013. It worked fine until it didn't. in 2020, we called Sondrini Enterprises, and they came within a week to investigate and fix the issue. It needed a new motor. In the spring of 2024, the awning motor seemed to again be broken. We called again and Nate Sondrini, personally, was able to diagnose and, over the phone, provided us with simple step-by-step instructions that resulted in solving, what turned out to be a very simple problem. These folks are smart, competent and reasonably priced! Would have no issue using them again!"

"Keith did a great job helping us obtain the building permit, explaining the decking options, and designing the deck. The deck completely covers old concrete steps and makes entrance into our home much easier. Keith used Trex material for the deck, which is maintenance free; he negotiated a good deal with the supplier for the color which closely matched our other deck. He suggested a local electrician for us to consult about lights along the stairs. Keith communicated with us in a timely basis and we always knew his schedule. We would not hesitate to hire Keith again for another project."

"Class General Contracting has done roofing and construction work on our over 100 year old house, and each time their price has been fair and the quality and service have been excellent. Recently we thought we saw a shingle missing from the roof and called them. They returned our call immediately and came over. We really felt foolish when it turned out to be a shadow, but Brian said no charge. Brian honors his warranties and his word."

"Phil Catanzaro was great to work with from start to finish. I appreciated him checking in before, during, and after the project. Requesting the quote and scheduling the work was seamless, and the crew was friendly, fast, efficient, and skilled. I will definitely recommend them to my friends and neighbors, and will reach out to them again for any future work."

"Barn Rescue – My barn was hit by a vehicle, which broke a large post and pushed section of siding out from under the roofline, plus major damage at ground level. Brad shored it up for the winter with an array of jacks and an enormous chain to ensure the thing wouldn’t fall down till they could return in the spring. Come spring, they fully replaced the damaged section’s support members and facade, and added bracing to the attic, rendering it stronger than before. Foundation support: The sagging beams and jerry-rigged support columns in the dirt basement of our 18th century house were inadequate. They dug and poured a dozen footings and lally columns, supporting a line of new 6x6 and 9x9 beams that provide solid support to the house above. They showed up promptly every day, worked fast, and left the site clean and finished. Both Brad and Chad have a deep knowledge about old houses and the techniques that were used, and I felt my historic register property was in good hands."
