"Nonstop home improvements were great! They were recommended to us, and I would highly recommend them as well. They thoroughly took care of us, addressing any concerns we had and made the roof replacement easy. They tore up two layers of shingles, replaced the wood underneath and layered new shingles. All for a fair price!"

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"Was very impressed from start to finish. They came to give me an estimate and showed me exactly the difference in why roofing has so many pricing options. I went with the best quality system and Iâ m very happy. I watched the entire install front he morning when they arrive at 8am and finished by 4pm. I was shocked it all got done in one day and how they cleaned up."
