What reviewers report — the concerns
Other directories bury these. We think you should read them before you call. Every concern below comes from the reviews it cites.
Red flag
Marketing email system is broken and unresponsive. One customer reports unsubscribe button does not function, receives frequent unsolicited review request emails, and follow-up emails to non-noreply addresses go unanswered. This is a customer service/operational issue, not a plumbing issue.

The evidence — in reviewers' own words
Critical
“Plumbing was fine. Price was fine. The fact that the unsubscribe button on their emails doesn't actually unsubscribe is NOT fine. Not only was I signed up for marketing emails I didn't want (seriously, plumbing service is not a luxury good--marketing emails won't get me to install a garbage disposal every 3 months) but this ridiculous review request seems to be sent every other week now. Because the unsubscribe …”
“Called for estimate on a heat pump water heater and got incorrect information from the person on the phone. The ballpark figures for the job were out of whack - they said $4k just for the unit which is way too high. I don't understand why plumbers steer towards gas when heat pumps are far more efficient. Will be calling another plumber for an estimate on hookup. For reference, even an 80 gallon Rheem heat pump can …”
“I got a deal with them through Angie's list. They came to do a flush and refused to do it as my water heater was old. When I said there was no disclaimer or conditions to the flush stated on the offer, they checked with the "manager" and came back and said they won't do it. Mind you, they did not check the water heater. They just looked at it from the outside, said it was too old to flush (it is a 1997). They …”

“Great job! Richard and his helper were right on it for a propane gas water heater replacement, checked out everything, installed the same-fit/size replacement that we had lined up already right there, and amazingly, they were done in exactly one hour! That included re-soldering the hard-piped high-pressure relief pipe back together that needed to be removed just to do the install. Quick work, and great …”
“Great work by these guys at reasonable prices. I had to have a Pressure Reduction Valve replaced which had caused damage to my Hot Water Heater Pressure Valves and a busted sprinkler line. The team came out and fixed it up. Super friendly and courteous. Ask for Curtis he was fantastic!”
