Recommended Customer Reviews

Patrick came out and replaced our old/broken hot water heater with an instant hot water heater very quickly. He had no problems even though we had a very strange exhaust setup on the old one. Communication was great, and I definitely plan on reaching out to him for plumbing problems in the future.

No words to say how great Patrick is! He can fix anything, knowledgeable in all things plumbing from years of experience, great person and someone I love to support!

Patrick came out to bail me out when my hot water heater quit working...right before vacation (of course). He was on the ball and sourced out a heater for me, got a team ready and came out to begin...only to find the source of the problem was a much easier solution than we had planned. His honesty and integrity shown through and he fixed the problem for me at a much smaller price than we had originally planned on. For that I owe him immensely (and figuratively).

I'm a single mom and my son clogged the toilet with a toy, i think? Called Brosnan plumbing and he came out on a Saturday and ""snaked"" ? The toilet but he got it cleared!! He charged me week day rates even though it was on Saturday! One thing less I have to deal with!!!
