"We had a issue with our shower and regulating the hot water. We had Kevin put in a new handle and cartridge system. Kevin did a great job installing and cleaning up afterwards. Would hire again."

"Excellent job! Good Guy Plumbing fixed my leaking water heater quickly and thoroughly for a fair price. Spoke with Robert over the phone and David came out to do the repair. Both were professional, knowledgeable and kind. I recently bought a new townhome and will be doing business with them for any future plumbing needs. Many thanks to David, Robert and Good Guy Plumbing. It’s such a relief knowing there are good, honest plumbers I can count on."

"Kayvan was a wonderful service tech! He was on time and professionally checked out the water heater and the HVAC system. He was so polite and friendly. He explained the need for a new filter in the heating unit and showed me photos of the unit located in the attic. He also offered to do a friendly deed for free, which I greatly appreciated, He’s a great asset to Service Champions!"

"They called us quickly and got a plumber out within a few days. Super thorough - tested all pipes and water sources to diagnose the problem. They were able to perform maintenance on most bathrooms the same day and improve the water temperature in our showers. Gave helpful, non-biased advice on potential further plumbing improvements. We will likely call this company again for any and all future plumbing needs."

"The installation was very efficient and the crew did an excellent job in regards to the plumbing hookups and testing. I highly recommend this company and would use them for future projects. I want to comment that this job was in a second floor condominium with very steep stairs and no elevator. To those who wonder how a very heavy 50 gallon water heater is naviga!ted down those stairs without scarring the newly painted walls, l can only say they managed perfectly. No dings anywhere. Good job guys"
