Flaherty Construction

Flaherty Construction is a Cambridge masonry, paving and waterproofing contractor working under James, though its Massachusetts home improvement contractor registration is currently listed as expired. Google shows 4 stars from 8 ratings — a mix that splits sharply by when the review was written. The earlier reviews, from March and October 2025, describe specific finished work: a fieldstone foundation that had been leaking for a long time got masonry repair and a full waterproofing treatment, work that followed an earlier roof job for the same customer's mother; a paved sidewalk and patio job left the site clean and tidy; another reviewer describes the crew as on schedule and communicative from consultation through the final walk-through. Then, in March 2026, two one-star reviews landed within a day of each other and describe a sharply different experience — one says work done in the home "started falling apart within months" and calls the company "unprofessional, careless, and abysmally incompetent"; the other reports poor-quality work that damaged the reviewer's property. Neither gives much specific detail about the job involved, but both are recent and there's been no review activity since to indicate what, if anything, changed. One thing worth flagging directly: the website captured for this business describes a masonry and roofing contractor at a Los Angeles, California address — not Cambridge — so its self-reported claims aren't used to describe this business here. Given the expired registration and the sharp, recent turn in reviews, it's worth asking directly about licensing status and getting references from a completed 2025 or 2026 job before hiring.
