Came home to my central a/c not working. After checking a few things, I called Masi Plumbing, based off of consumer reviews here. The person who answered the phone was accommodating to my needs and had a service person here super promptly! The service person was very friendly, highly informative and fixed the issue promptly- and not at a high cost either! Will def be calling them for our needs again, and referring them as well. Thanks a million Masi Plumbing!

My pipes froze and burst on a Sunday evening. I called several plumbers who would not give me the time of day. MASI Plumbing to the rescue! They sent a plumber (Nick) out immediately who was able to repair the broken pipes that evening, even though though he had already worked all day! A huge thank you! I highly recommend MASI Plumbing and will be using them exclusively in the future.

Bought a new boiler system from them this year and they gave us the most comprehensive quote for the right work (pointed out the need for fresh air and a new oil line which we knew were needed) at a good price. Unfortunately one of our parts in the system failed, but they had it replaced and our system up and running within 2 hours, and covered under warranty, so no cost to us. They have always been very friendly, down to earth, but professional. Great to work with!
