"Was selling my apartment and wanted to service heater prior to listing. Moore provided great technicians who tried everything they could to reset and fix some mechanical issues. Provided lots of info and updates while they worked, showed me everything they were doing, where problems were, etc. In the end, the heater was too far gone and a whole replacement was recommended. Moore was able to schedule the replacement within a week. Whole project was completed in 4.5 hours and came in under their initial estimate. 10/10 would recommend them to all friends and family."

Your plumbing problem becomes our problem to solve.\n\nThat’s not just a tagline, it’s how we operate. When you call GOFLOW, you’re getting a team that knows this area, knows plumbing, and genuinely cares about doing the job right.\n\nWe’re not a franchise. We’re not a call center routing you to whoever’s available. We’re a local company built by plumbers who got tired of watching customers get treated like transactions instead of people.

"The water heater repair was $400 and they wanted to charge us the $300 for the bathroom leak, but we told them it was ridiculous because the guy was only here for 5 minutes. They ended up crediting us some money back so they handled that really well. Less than 2 days later the water heater broke. They did not send out the same guy. They guy they sent out was really great, he walked us through every minute and dime he spent. He told us not to worry and that we were getting our money's worth. We've used them many times over the last 7 years. Once it was Christmas Eve and the hot water heater was having problems and they came out and repaired it for free. Then there was another time that I needd a $6,000 repair and I didn't have time to get estimates, but I trusted their work. The work has been quality, I think in the future with them I will ask them upfront for an assessment and not pay them until they start doing the work."
