Leak Repairs & Clogged Drains

At the first sign of a leak or clogged drain, don’t hesitate to call on MASI Plumbing, Heating & A/C for prompt, affordable service in Southern New Hampshire.

The consequences of blocked pipes are far worse than standing water in the sink or tub. The increase of internal water pressure can lead to pipes cracking or even bursting. Since water always searches out a way to escape, the damage can show up just about anywhere. Water seepage destroys walls, causes wood rot, and creates the ideal habitat for mold growth and insects. Let our licensed plumbers prevent further problems with affordable and effective solutions.

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!
