Christopher C Allen is a sole-owner general contractor based in Middleton, working across the Boston area on additions, roofing, siding and deck jobs. The clearest picture of the work comes from Massachusetts building permits rather than customer write-ups: a rear addition in Waban that grew to $200,000, a $520,000 addition in Belmont, a combined kitchen addition and three-bathroom remodel also in Waban, plus reroofing and vinyl-siding jobs in Charlestown and two reroofs in Beverly, with the oldest dated to 2011. BuildZoom lists a Construction Supervisor license (#CS-075275) as active. The same page describes "15 years of experience," but that line is BuildZoom's own generated copy on a profile the site itself invites the business to claim, not something Allen has stated directly — worth confirming before assuming it as fact. Anyone considering a project in this range should ask directly about current licensing, insurance, and recent references, since the permit record alone doesn't speak to how the work or the process felt to those who hired him.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Christopher C Allen. Use it to sanity-check bids, then get the real number in writing.
