Cornerstone Construction & Remodeling

Cornerstone Construction & Remodeling is a Westford, Massachusetts general contractor and remodeler that also lists insulation and spray-foam weatherization among its services, working across roughly twenty Merrimack Valley towns from Acton and Chelmsford to Nashua, New Hampshire. The one detailed customer account on file, a 2021 basement remodel, describes a competitive quote, on-time and on-budget completion, and a team that answered questions throughout the project and offered advice on other work around the house — specific, first-hand praise rather than a marketing line. Houzz and BuildZoom both list the company at 69 Broadway Street with the phone number (978) 692-3938, and both cite an active Massachusetts Construction Supervisor license, #CS-111195. BuildZoom separately shows an older Home Improvement Contractor registration, #169913, as inactive, while Houzz's own awards section still names an "HIC contractor license" without that caveat — the two platforms don't fully agree on its current status, worth confirming directly before signing anything that needs HIC coverage. Beyond the one on-record project, the company's stated service list runs from kitchen and bathroom remodels to siding, flooring, and historic restoration, and it explicitly offers insulation installation and spray foam insulation. Anyone looking specifically for weatherization work should ask what share of their recent jobs are insulation versus general remodeling, since the only documented review is for a basement remodel.
