M H Barnes

$275 dollars to not even properly diagnose whether or not they fixed the problem because the plumber was unable to read my meter ( not their fault but I was under the impression they'd return and this doesn't seem to be the case ). The 275 dollars was a charge to change 3 flappers, one of which was brand new because we had a different plumber come not even 2 weeks earlier. I used MH because they were listed on the WSSC website as master plumbers but I sincerely wish I had just stayed with Len the Plumber. Additionally their billing system is RIDICULOUS . You can't hand the plumber payment at the time you have to wait to receive an invoice and then you can't even pay online (??????????) You have to call to provide cc information over the phone or send a check in by mail ?!??!?! Both of tho

Shawn did a great job installing my toilet. Fast, friendly, and everything works perfectly. Highly recommend!

Echoing other reviews -- I wouldn't recommend Barnes Plumbing. They installed a sump pump battery backup in my house in November 2022 and it started beeping with an error message in December 2024. When someone from Barnes came out in January 2025, they said the battery was dead and should have lasted 5 years but they couldn't do anything about it because the manufacturer only had a 1 year warranty. They said it would cost over $500 to replace a battery that was only 2 years old and was defective. And then they charged me $130 for someone to just come out to my place without even telling me that there was a charge for that (and told me I "should have asked" when I asked why I wasn't informed of the charge). They said the $130 was for a minor fix they did that took 4-5 minutes total, so

Barnes came highly recommended from our friends. They are very professional, timely and fairly priced. Every time they have come to our home, they have fixed the problem with as little hassle as possible.

Do not use MH Barnes for Heat Pump Hot Water Heaters. We had them install an AO Smith water heater 22 months ago. They had promised a unit with a 10 year warranty and delivered a unit with a six year warrantly. After six months the heat pump portion of it failed. They could not diagnose it. They sent out a junior person when it failed who knew nothing about heat pump hot water heaters. We called repeatedly for follwo up after this one visit. Barnes did not return phone calls.They did not help us with a warranty claim. After we reached out to AO Smith directly, they helped us diagnose the failure using two simple thermometers and the software on the heat pump. AO Smith offered a warranty replacement. I would not have Barnes do any work for us again.
