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.

I had a major leak in the bathroom and the drainage pipe blew out under the kitchen sink – two problems at one time. It was an emergency. My building management got in contact with these guys and they totally came through. I hadn’t been able to take a shower in a couple of days in this hot weather. It never felt so good to get clean again. With Anita manning the phones and Roberto as pipe whisperer I think any plumbing problem will be tackled with finesse. Cheers to these guys gals in this wonderful City. I’m out.Jean-Paul N.
