Coulter Construction

Coulter Construction is a three-person Billerica outfit that has been working since 1998, according to its Better Business Bureau file, which names Derek Coulter as owner and grades the company A+. What homeowners have written is thin and dated. The one review on file, from 2020, comes from an architect who says he hires Coulter regularly and had him work through his own house — a dormer for a new master bathroom, a new window and sliding glass doors, two decks, interior demolition on the second floor, an attic ventilation system. His point was less about finish than about bids: typically the low bidder, and the job done without change orders. The company has also turned up in a Massachusetts town's select board minutes, which recorded recommendations from historical groups and described Coulter as flexible and responsive on a municipal repair bid. Its own site is a single page of contact details under the line "Building Boston and Beyond." If you're weighing them for a remodel or an addition, ask for recent references and photos of finished jobs — the one homeowner account you can read online dates to 2020.
