Coolock Construction

Coolock Construction is David McGrath's Boston-based remodeling and general contracting outfit, and its Massachusetts home improvement contractor registration checks out against the state registry as active. The written record backs that up: 11 reviews spanning 2019 through this year describe a wide range of work — a new roof in Back Bay, a kitchen ceiling and wall rebuilt after a burst-pipe flood, an AC return vent installed with enough care that David thought to match the drywall paint before the customer even asked, a deck build this spring. What comes through repeatedly is responsiveness and follow-through rather than just finished work. One customer, four years into working with him by the time of their review, describes David as willing to fix problems 'even if it's on the weekend or over a holiday,' and lists having hired him across bathroom, kitchen, roofing, closets, staircases, painting, electrical, plumbing and windows — a track record with one contractor across a genuinely wide range of trades. Another describes a rush job — sound and air sealing work involving tearing open walls, spray foam, drywall and painting — finished in four days with daily photo updates. Houzz backs the review record with a 2x Best of Houzz award and perfect 5.0 sub-scores for work quality, communication and value across its own eight reviews, plus a 'Verified License' badge (no number shown there). The BBB grades the company A+, though it isn't BBB-accredited — a real distinction, not a discrepancy, since accreditation and grade are separate BBB measures. One thing to note: the address and phone on file with Houzz (Boston's Back Bay) differ from the ones BBB has on record (East Walpole) — likely just an older or secondary listing rather than anything to worry about, but worth a quick confirmation when reaching out. For a homeowner in Boston's inner neighborhoods looking for a general contractor who handles everything from a roof to a bathroom to a rush repair, Coolock's record — verified license plus years of specific, corroborated praise — is about as solid as this kind of small operation gets.
