Mike is officially my new plumber! The water was overflowing in my new basement shower, and I had no idea why. Within 5 minutes, Mike told & showed me exactly what the issue was. The problem was resolved in less than 30 minutes. If youre looking for a knowledgeable plumber with 45 years of experience, hire Mike for the job and you wont regret it! And get this, he recommended someone to clean & disinfect my floors within an hour. Thanks Mike!

I always call Sal Manzos in an emergency it seems and they always come through and take care of me while I am melting down. This time we needed our main waste line snaking out after it was completely blocked and backing up into the washing machine.
Mike and Mike (seriously) were super, knowledgeable, clean, tidy and funny. My basement is now dry with fully functioning pipes

When plumbing fails on the weekend, we typically had to wait until Monday for help. Sal Manzo Plumbing immediately answered our call and sent Chris to the rescue. He kindly answered our questions and then very efficiently went to work on resolving our problems. Chris did a wonderful job of repairing the issues and has a great personality so it was fantastic to have his help. We highly recommend Sal Manzo Plumbing and the terrific service Chris provided. THANKS! Update: another weekend shout out for help with Sal Manzos Chriss to the rescue again. A super jobkudos!

Absolutely terrible service, most unprofessional group of individuals Ive ever come across, came to fix and leak in a washing machine drain and almost got into a physical altercation with my 85-year-old father. Not only should this group of individuals be out of business but they should be arrested. Im driving there tonight to drop off applications for Burger King they all need to get a real job and learn some customer service!

Thank you to Jay Rockerfeller for a fantastic job today. He was courteous and friendly! He and his assistant treated me very well and were very clean and neat and explain everything that needed to be done to my cooling and heating system.
