Just found out yesterday they installed a non-potable expansion tank on my water heater in 2018. Absolutely disgusted at what was dumped out of that tank yesterday and thankful we have a Brita.

WARNING The phone number now rings to JP Contracting and Joe Pitzo is a criminal. They take $59 upfront to secure a spot on the schedule. Then they never show up. It’s a complete scam and I have reported it but also want to warn people here.

After my usual plumber botched a job and decided to try to up-sell me an additional service contract rather than fix it, I started looking for a replacement. Brendan Walsh replied to my inquiry right away. They told me they didn't really do onsite free estimates, but then got back to me right away to tell me they would be in the area and could come by that afternoon. They sent an estimate only a few hours later. They did the job they were hired for but then they fixed the job my "former" plumber botched and did not charge me. The cost was about $70 less than my former plumber quoted and they offered

Thank you for your professional and honest assessment of my sewer line. I own a rental property were during the annual inspection the township speculated because of a settling walkway the sewer line might be failing. They referred me to a company who came out and inspected the line (shot a video). The company sent the video to the township who called and said the line needs to be replaced. I found Brendan Walsh after an online search. In speaking with Craig, he said he was a master plumber who could certify whether or not the line was failing. He came out inspected and certified that the line was

Craig, Will, and Alex did a great job installing my new dishwasher. Home Depot could not install it due to the slightly elevated floor. However, Brendan Walsh Plumbing was able to access the situation on the same day that I called (a Saturday) and return on Monday for the installation. Home Depot also left a part for the installation, but Craig had the part in his truck. I highly recommend Brendan Walsh Plumbing.

Brendan Walsh Plumbing was awesome. I called them with an emergency drain backup in my basement and they were out at the property within two hours. All of the staff that I interacted with were friendly, professional, and informative. They resolved the issue quickly and it was affordable. Thanks Craig and crew!

We had a wonderful experience with Brendan Walsh Plumbing!! They were extremely friendly and accommodating. They were able to go out and perform a sewer lateral inspection for our client in a timely and professional manner. Darlene, in the office, was very thorough and kind and made sure we were taken care of. Brendan was very knowledgeable and extremely helpful. His vast experience certainly showed in his work and in the information he provided us on this inspection and any future inspections or work that we may need in the future. We will definitely be recommending them to any of our clients
