"Given the fact that having a water heater fail is never a fun experience, Joe and his team did such a fantastic job of making the situation so much better for us. Honest, hard working, fair pricing, and quality work. They were honestly a lifesaver given my wife was recently pregnant and being without hot water is not an option.

"I needed 2 backflow preventers replaced , a water heater repaired and a to0ilet repaired. I had a quote from a very famous local plumbing/heating company for $4000! I called Doug for a second opinion and he came in at HALF the price!! and that was AFTER I showed him the first quote! He didn't seem surprised at all about the first quote. Not only was he half the price but he pointed out that my 6 year warranty on my water heater had 6 months left and said I could get a new one thru that warranty for $100!!! He took care of going thru the company getting me the new heater. He completed the job in a few hours. I will NEVER call another plumber again! My recommendation is to run, not walk, to get Doug for your needs. On top of that he is so very nice. I would give 10 stars if I could."
