"Proffesional installation by Hector and Michael. They installed Bradford White Water Heater, and day before installation I called and asked Hector if they can install also Halo 5 water treatment system, self cleaning, and he said Yes! Clean, speedy job. Great price. Effective, fast communication. Hector answered my questions via phone, text, email literally within minutes, or instantly. Highly recommend this crew, company. Already informed my family, if they need fast, reliable service, installation of new systems, to contact them. GO SPEEDY WATER HEATERS!!!! Thank You for great service, consultation, explanations, answering all my questionsin details, fast, and installation for great price. I would give them 6 Stars, if I could."

"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."

"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."

"Can not say enough positive things about this company. Usually do alot of things diy, but i would hire them any time to do plumbing. Their professionalism is way above board. Prices more than fair. Miguel is a definite asset to this company. When i have a plumbing problem i will definitely call them back. (had another company come before them that could not get the job done and suggested replacing the trap under my bathtub. My home is not on a foundation but a slab, and that means removal of my bathtub. The cost of his visit would have gone from one hundred dollars to thousands. ) Thank you Service Champions!"

"Also had them install faucets, do pipe repair, and clear drains. They were on time, easy to communicate with, returned calls in a timely manner, discussed job prior to starting, and looked for the most cost effective way to solve whatever the issue was."
