After arriving and determining exactly what was needed the tech left and returned about an hour later with a new tank and all the necessary parts to get me hot water all in the same day. Their work was very clean and at a great price!!!

Eduart from Maxwell Plumbing did a great job at one of our properties on 5th Ave. He was very professional and knowledgeable. He completed the work on time and within budget. He worked well with tenants in a high-end academic environment. He was able to move work around to accommodate the demanding schedules. I would highly recommend him and Maxwell for any work.B Keenan

My client retained another plumber as part of a larger renovation. All aspects of the job were very poorly handled until Maxwell Plumb Mechanical Corp. stepped in. Through their hard work, a project that had been a four-year nightmare was closed out in a matter of days. They even handled an aspect of the job that wasn't their responsibility in order to provide the best possible service to their customer. I highly recommend Maxwell Plumb Mechanical Corp. for their professionalism, expertise, prompt communication, innovative solutions, and overall excellence.Mina K.
