"I highly recommend A1 Everlast to anyone looking for a reliable, skilled, and trustworthy company. They were punctual, respectful, and kept the worksite clean. We were always kept in the loop, and they responded quickly to any questions we had. They also finished the work in the time frame that was told to us from the beginning. The final result meets beyond our expectations. I highly recommend A1 Everlast. We mainly dealt with Anthony and Bob. Both were phenomenal and detailed in their work (sent us pictures of the work completed daily). Our work was basement water proofing. The best thing about this company is everything is in house (No outside carpenter, electrician) He had his own trusted people.
