Edward F. Corcoran Plumbing & Heating Co., Inc.

The first thing a homeowner should know about E.F. Corcoran is that the company says it doesn't do residential work. Its own site puts it plainly: plumbing and HVAC for commercial, industrial, institutional and medical properties, across Massachusetts and into northern Connecticut, run out of 5 Rose Place in Springfield. That focus shapes everything else. This is a mechanical contractor rather than a call-a-plumber shop — 24-hour service, gas piping, boilers and heat recovery, the mix a BusinessWest piece described in October 2025 alongside work for hospitals, colleges and a supermarket chain. WWLP reported the company among the 2025 Springfield Super 60 revenue-category winners. The company traces itself to 1963 and Edward (Ted) Corcoran, says his son Jack succeeded him, and that Susan and Alyssa Toomey own and operate it now — the second family to run it. It calls itself family-owned and a union shop affiliated with Local 104 Plumbers and Pipefitters. Its BBB page, which is not accredited, carries an A+ and lists the same July 1963 start date. There isn't much written about them for a firm that old: three Google reviews since September 2025, and a 4.7 average across six ratings. The most telling one isn't from a homeowner at all. In September 2025 a facilities-contracting firm wrote that Corcoran sits at the top of its list — efficient, competent, cost-effective on the solutions it brings. A July 2026 review describes a sink repair done on time, with the plumber and the office staff keeping the customer in the loop from booking through completion. The counterweight is specific and worth reading. In December 2025 a vocational shop teacher described a contracted salon shampoo-bowl installation for a classroom that ran well past a month unfinished, with the parts not ordered ahead and a first visit that couldn't be completed for want of them. One thing to pin down before signing anything: the company publishes "Corporate License # 3302" on its own site, and the Massachusetts plumbing registry record for that number comes back expired — and listed to Thomas J Twiggs rather than to the company. Ask which current licence covers your job and who holds it. If you run a building — a school, a clinic, a plant — this is the kind of shop that picks up at 2 a.m. and knows its way around a boiler room. If you need something fixed at your house, they say up front to call someone else.
