Typical Greater Boston range for this kind of work, from regional averages — not a quote from Constantino & Company Plumbing/Heating. Use it to sanity-check bids, then get the real number in writing.
Water heater specialist — frequent installs and repairs
Licensed plumber — active MA registration, registry-verified
BBB accredited — A grade since 2025
Tidy work — shoe covers, cleanup noted repeatedly
Constantino & Company Plumbing/Heating is a Beverly-area outfit run by owner Alex Constantino, whose Massachusetts plumbing license is active and registry-verified. The company holds a 4.9-star average across 73 Google ratings and an A grade with the BBB — accredited since April 2025 — with 69 reviews on file since 2024.
Speed is the thread running through almost every account. A recent review describes the company diagnosing both low water pressure and a failing water heater the same day it was called, and another recounts fixing a kitchen leak the day it happened, with technician Nick handling the visit. In a February 2026 review, Alex and a colleague showed up 30 minutes after a 6pm call about a leak at the meter horn on one of the coldest nights of the year, avoiding a repeat of the frozen-pipe trouble neighbors were having that same night. In a December 2025 review, Constantino was the only company that responded at all after a customer needed a wall cut open to reach a shower valve, and another from the same month describes a burst kitchen sink fixed within a half hour of the call.
Water heater installs and repairs show up repeatedly — a recent review calls one 'neat and clean,' and in a March 2025 review a hot water heater that died overnight was replaced the following morning. The crew also handles faucet and fixture installs and, in a September 2025 review, ran a new gas line for an outdoor grill. One recent review specifically credits Alex and Nick with resolving 'plumbing and heating woes,' consistent with the heating and hydronic-heating work the BBB lists alongside plumbing.
There's little to flag — the last six months brought 10 reviews and zero negative ones, and no complaints turn up anywhere in the 69-review history on file. For plumbing or heating work on the North Shore — an emergency leak, a water heater replacement, a fixture swap — this is a shop reviewers describe calling back for the next project too.

These guys did a whole house water filter for me. They did a great job very clean professionally done, they got me on schedule quick and showed up on time. Definitely will use them again and recommend them to anyone.
My mother Marilyn just wanted to drop 5 stars (she can’t do it on her own phone for some reason); she has been raving about the two young professional gentlemen who came and provided spectacular service in three different areas on the property. The pricing was better than the others and they were quick to respond to our requests for services. We highly recommend them and will be the the only plumbers we call moving forward.
Constantino and Company is the best of the best. They always make themselves available and are very trustworthy/honest people! Can’t recommend them enough! Best plumbers on the North Shore!
