Forty years in Milton, and the service list runs further than most plumbers'. Alongside the boilers, hot water tanks and gas fitting, S.G. Harold does radiant floor heating and snow melting — the kind of work that turns up on driveways and walkways rather than under sinks. The BBB records it as a seven-employee sole proprietorship under Stephen G. Harold, started in January 1986, taking both residential and commercial jobs, with Stephanie Bourget running the office. It grades the business A+, though the company has not sought BBB accreditation, and lists its hours as round the clock, seven days a week. Beyond that there is very little to go on — the BBB page carries no customer reviews and no complaint count. For a plumbing, heating or air conditioning job in Milton and the towns around it, the tenure and the breadth of that service list are what the record actually supports. Ask for the current plumbing licence and a couple of recent references, and judge the rest on the conversation.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from SG Harold Plumbing Heating & AC. Use it to sanity-check bids, then get the real number in writing.
