Report
Masi Plumbing deserves 5 stars. I called them with a broken grey water pipe. They came out promptly to fix it in just two days. The plumber was knowledgeable and did quality work at a fair price. I appreciate their fast, accurate service. Masi Plumbing is reliable and highly recommended.

Report
I had an old furnace that went down during a multi-day single digit cold spell; the kind where getting a heating contractor in short oder is impossible. The phone message I left late the evening before was answered first thing the following day and I was advised that they were swamped but would get to me ASAP. Service arrived a day later which was difficult on the household but well within a reasonable turnaround under the circumstances of the frigid temps.
When their plumber arrived he listened to every detail I had to tell him about what I had observed and then rolled up his sleeves for the next two hours to bring my old furnace back online. Overall I was happy with the job done. Honestly, parts are expensive off the truck but the labor charges and service call charge was within the range I exoected to pay. I guess the most poignant testamony I can give is that any additional work I need in the future I would call Masi Plumbing and Heating as my primary contractor.
