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.

This will be an odd review, because I did not actually hire the company. That said, Michael came over to view my job, which involved excess water off my property impacting my next door neighbor. I thought I was going to have to rejigger all of my gutters for thousands of dollars, but Michael identified the real problem as lying in my neighbor's driveway, which had a dip next to his basement door where all of the water collected. Plus, his drainage system had never been cleaned (he's owned the building for 24 years). The solution then that Michael urged us to was first for my neighbor to contact Roto Router to clean out his drains. In the event that didn't do the trick, another easy solution he suggested was redirecting my downspout from the back of the building to the front. So, while I had no need to hire Primestone, the advice my neighbor and I received (for free!) was sufficient to resolve the problem for the present, and likely into the future. Many thanks Michael!
As a real estate attorney I'm always nervous about contractors. Thomas and his team were dedicated and professional down to coming in and out through a hutch so they would not track dust. We are quite happy with the service and communication. This is the type of old school care about one's business we don't see enough these days. Highly recommend
Brick and Stone Patios, Walks, and Steps - Install ($8,500). Thomas and his crew were amazing. They finished this job in a little over a day. They left the area spotless and I couldn't be happier. Worth every penny. They removed the original brick walkway and hauled away bricks.
Excellent job on my patio and wall no more water buildup or ants it's a little late but thank you thomas
I had Tomas for a quote for my front stairs he explained the posses and the engineer view of the work he came did a great job I recommend him for any type of work Great job Ted Leotsakos
