John S Tremblay

John S Tremblay is a contractor listed with a local address at 8 Ruthven Ave in Middleton, Massachusetts and a headquarters address in Chester, New Hampshire, reachable on (781) 760-0204. The permitted work on file is heating and cooling installation, not the windows and siding this listing was filed under. Across 2020 to 2022 the permits show sheet-metal jobs in Lexington: pairs of gas- and propane-fired furnaces installed with air conditioning and duct systems, at valuations between $10,000 and $20,000. Seventy-six permitted projects are recorded in total, making this a working contractor with real volume behind it. There is no customer feedback to weigh that against. BuildZoom states it has received no reviews and publishes no star average; the 91 shown there is calculated from permit and licence records rather than from anyone who hired him. The credential picture needs care before hiring. Eight licence records are listed across six types. Two different construction supervisor numbers, CS-107887 and CS-097047, are both reported verified active as of July 2026, while a third, CS-096376, is reported cancelled. A single number, CSSL-099483, appears three times under three different specialty types — construction supervisor specialty, roofing, and windows and siding — all reported cancelled, as is home improvement contractor registration 155627. A landscape architect record numbered 847 is shown active but unverified with a January 2014 expiration. The same profile names the owner as John T. Tremblay rather than John S. All of that comes from the directory, not the state. If you are hiring for heating or cooling work, ask which construction supervisor licence is current, confirm it with the Massachusetts Department of Public Safety, and ask about the cancelled home improvement registration before any nonstructural residential work begins.
