Report
Very pleased with the work done. I called them to replace two hose bibs/outdoor spigots. They were pleasant on the phone and scheduled me quickly. They charged a fair price and the two plumbers were extremely thorough in fixing the issue. They took their time to explain my options and walk me through the pros and cons of each.

As disappointing because they are quite expensive($150) for their initial estimate which took literally 20 min only to look at to figure out the just brand of the toilet. they do not use that amount towards the actual repair and charge an additional $175 for the repair. Service: Toilet repair

Report
We purchased a new hot water heater from a plumber who doesn't service what he sells. I did not know that at he time, my bad. In searching for an authorized AO Smith Plumber, I came across Master Plumbing and Mechanical. They were awesome, showing me how to get the service call covered by my AO Smith warranty, coming out quickly even though they didn't do the install. And once the part needed was received, they were out almost immediately. Jack was our guy, he was timely, polite, professional. I will refer Master Plumbing to others every chance I get.

Master plumbing is a fantastic, reliable plumbing service. We have done extensive work with them, including on our radiator systems, drains, toilets, faucets, and water heater. They are one of the only shops I know of that actually do the work themselves (ie, done by their master plumbers). They are highly knowledgeable and thorough.
