Lexington is in Middlesex County, Massachusetts, established in 1713 and home to roughly 34,500 people. It was settled well before the Republic, which usually means a core of Federal and Greek Revival homes surrounded by later infill — plenty of hand-framed structure, and rooflines never meant to carry today's insulation. For a contractor that makes it a mid-sized town with a genuinely varied housing stock, from the oldest streets to recent construction. It sits in Greater Boston. It is about 30 miles from our Northborough shop — about 45 minutes to an hour in normal traffic. Being close keeps estimates and site visits quick.
