Last 6 months: 0 reviews, 0 negative. ## The honest read Primestone Home Improvement is a Boston-based masonry and waterproofing outfit that says it's been in the family for three generations and more than 35 years. Its reviews line up with that description of old-school craftsmanship — most of the work described is masonry and hardscaping: retaining walls, paver patios, brick and stone steps, and driveways, with basement waterproofing and foundation repair among the company's stated specialties alongside that. The written record is small but consistent and skews toward the responsive and the hand-built. When a retaining wall holding up an above-ground pool started collapsing, the crew (led by Michael) was on site the same day the customer called and had the whole section rebuilt within two days. A separate $8,500 brick-and-stone patio, walkway, and steps job — including hauling away the old brick — was finished in just over a day and left, in the customer's words, spotless. One reviewer who never actually hired Primestone still left a review: after Michael came to look at drainage complaints from a neighbor, he traced the real cause to a dip in the neighbor's own driveway rather than pushing an expensive gutter overhaul. Nothing in the record raises a real concern — one reviewer noted the work finished a little later than hoped, but was otherwise happy with the water and ant problems it solved. Angi's profile lists a Massachusetts trade license for the company (expiring mid-2026), though that listing hasn't been independently verified against the state registry. With only a dozen reviews on file across Google and Angi, the sample is thin — but everything in it points the same direction: for retaining walls, patios, and masonry-adjacent foundation work, reviewers describe a crew that shows up fast and finishes clean. **Strengths:** - Fast response — rebuilt a collapsing retaining wall within two days - Clean finish — large patio job finished in a day, site left spotless **Concerns:** - Minor delay — one job finished a little later than expected ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Self-reported as a third-generation family business operating for more than 35 years _(confidence: medium)_ - [Official Website](https://www.primestoneboston.com) — “Company history (self-reported): States it has protected Boston homes from water damage and structural issues for more than 35 years as a th…” - [Official Website](https://www.primestoneboston.com) — “Ownership (self-reported): Third-generation family-owned business.” - [Official Website](https://www.primestoneboston.com) — “Self-reported 35 years in business” - Angi lists a Massachusetts trade license (#212781, expiring 07/28/2026) for the company; not independently verified against the state registry _(confidence: low)_ - [Angi](https://www.angi.com/companylist/us/ma/quincy/prime-stone-home-improvement-corp-reviews-1.htm) — “Angi profile for Prime Stone Home Improvement Corp (859 Willard St, Quincy, MA) shows a 5.0 rating from 3 reviews praising prompt, high-qual…” - Same-day response for a collapsing retaining wall supporting an above-ground pool, rebuilt within two days _(confidence: high)_ - [Angi](https://www.angi.com/companylist/us/ma/quincy/prime-stone-home-improvement-corp-reviews-1.htm) — “5★ Retaining Wall - Install.
