"Removed old water heater and installed tankless. Explained what needed to be done. There was some misunderstanding on what was needed that I said I would accomplish prior to their arrival. They stuck to their estimate even though they had to do additional work."

"The water company said that the entire meter well needed to be dug up and replaced to repair the leak. Several estimates for that were $2000-$4000. Amanda Plumbing found out from the water company that they could just replace the pipes in the meter well without excavation. However, in the end, the entire problem was resolved by just replacing a couple of gaskets. As President of the HOA, I was extremely happy with their solution and will definitely call them for any future plumbing needs."

"Excellent. We had other projects we wanted done, but they explained to us that installation of these fixtures (and a new outlet) would involved drywall being cut and they wanted us to know this before starting.  We decided this wasn't worth doing. 
They arrived for the estimate a few minutes early, and arrived the day to work right on time. Matt did the installation, and he was professional, courteous, neat and clean. He was only there 1/2  a day.

"Thank you , Brian Taylor for you excellent service Brian walked in like a BOSS!!! My hot water heater had been out for over a week. He said I can replace it today, He went to the hardware store brought back a quality water heater, he took out the old and installed the new. He left no mess behind including hauling away the old heater, I highly recommend this very respectful hard working man. Thank you Rescue Rooter for sending Brian."

Hi! I’m Matt and I’ve been plumbing for 2 years! I’ve worked with and installed many different systems, but I specialize in water heater install and service, repairing leaks in drainage and water pipes, and installing fixtures! I believe all work must be done neatly and to the home/business owner’s standards, no matter what.

"Keith Votaw and his crew member were very prompt, friendly, efficient and clean. The work that they did installing the water softening and filtration system I had purchased through home Depot was outstanding. He also offered me a maintenance package for the care of my system after I asked him about it. It was great that he di not do a sale to get me into spending more money with them because I bought my system somewhere else."
