Flaherty Construction

Flaherty Construction is a general contracting, masonry, and waterproofing outfit based in Cambridge, Massachusetts, operating under a Massachusetts Home Improvement Contractor license (currently listed as expired) held by Flaherty Construction Corporation. Homeowners who hired the crew, often describing a foreman named James, report specific completed work across foundation waterproofing, masonry, paving, and patios. A 2025 review describes the team waterproofing a fieldstone foundation that had been leaking for a long time and carrying out masonry work both inside and outside the home. Other 2025 reviews describe a newly paved sidewalk and patio left clean and tidy, and pavers customers were happy with. Reviewers who used the company for larger remodeling work in late 2025 describe a crew that stayed on schedule, kept the site clean, and communicated clearly throughout. That track record sits alongside two harsher reviews from March 2026, one describing work that began falling apart within months and another reporting poor-quality work and property damage during the job. Neither review names the specific trade involved. Anyone considering Flaherty Construction should confirm the company's current Massachusetts HIC license status directly, since state records show it has lapsed, and should get a written scope and timeline given the mixed recent feedback. For foundation waterproofing, masonry, and paving work the company has a history of named, specific completed jobs that satisfied customers — but the two 2026 complaints are recent enough to warrant asking for references from work done this year.
