Leitner Brothers Construction is a family-owned general contractor in Watertown, Massachusetts, run by John Leitner. The Better Business Bureau lists it as established in Massachusetts in 1996 with three employees, while Angi separately credits the family with 61 years of experience in the trade; a 2011 news piece described the founder working in partnership with his son, John. The company's own listings describe a broad renovation scope: additions, framing, finish work, and renovations per the Better Business Bureau, and basement, bathroom, and kitchen remodels plus multi-room renovations per Angi. BuildZoom shows 34 permitted projects on record for the business. For additions, framing, finish work, or a fuller room renovation, this looks like an established, family-run option — before booking, ask which license number currently applies to the work and confirm it directly with the state.
“He founded the Leitner Construction Company, later incorporating it as the Leitner Brother Construction Company. He was currently in partnership with his son John Leitner.”
