Liddell Plumbing & Heating LLC

Massachusetts lists master plumber licence 17005 as active, held by Timothy Liddell — and that licence is most of what can be confirmed about this Wilmington shop from outside its own front door. The work is plumbing, heating and gas fitting for houses and commercial buildings, with the company pointing to new construction and high-efficiency heating systems as its focus. Tim Liddell founded it and still runs it, and the site says he is on every job; that, and the 16 years in business it advertises, are the company's own claims rather than anything checked independently. The licence number printed in its footer matches the number on the state registry. Past that, the public trail is short. In a March 2025 r/SalemMA thread asking for plumbers, a commenter answered by posting a link to Liddell's Facebook page — a nod, but a bare one. The company also appears in the Wilmington/Tewksbury chamber's business directory. No customer reviews turned up on any of the usual sites, which is why there's no rating here rather than a generous one resting on almost nothing. If you want a licensed master plumber for a heating or gas-fitting job in the Wilmington area, this is a reasonable call to make — with the homework left to you. Ask for recent local references and a written scope before anyone starts.
