"Tony was the plumber that worked in my home. I give him an A+. He was extremely professional, polite and provided me with a clear and concise explanation of the problem and recommended solution. I should have used this company immediately rather than wasting time and money with less skilled neighborhood plumbers. I would recommend United Sewer & Water without hesistation!"

"I had plumbing leaks in a couple of places, but the men that did the work went above and beyond by replacing every component involved top to bottom to ensure there would be no leaks for a long time to come. Very satisfied with the quality of work as well as how quickly it was done."

"Bruce and Bill of Williams and Associates Mechanical Contracting recently removed and replaced my 18 year old oil fired boiler and added an indirect fired water heater. I had been saving for this project for over a year and had been geeking out in my avid research (Thanks Internet!) of products available, reviews and costs, as well as the reputation and reliability of local heating and plumbing contractors. I knew what I wanted, I just needed to stay within my budget and find a contractor I could trust. It is therefore, my pleasure to let others know, on the same web review sites that I referred to, how overwhelming pleased I am to have worked with Bruce Williams and his team. They skillfully removed and installed the heating system in a day, took pride in their work and took the time to explain the new system and to fully answer all my questions. Bruce and Bill clearly like what they do for a living, have great people skills and work very well together. I was able to get the very best of products and still come well under budget. I cannot thank these guys enough! Honest, Professional and Reliable! My dusty, unfinished basement with my new Viessmann boiler, Carlin burner and HTP indirect fired water heater is now my favorite part of the house!"
