Three Hills Masonry & Foundations is a Charlestown outfit that gets called when a basement stops staying dry. Nearly every homeowner who has written about them describes the same job: water coming through an old foundation, sometimes with a chimney involved, and a crew that stopped it. Its Massachusetts home improvement contractor registration is active — number 219738, held under the company's registered name, Three Hill Masonry & Foundations Corp. The business itself is new: BBB records it as started and incorporated on 7 May 2026, with one employee, and declines to rate it for lack of history. The written history is six Google reviews, all five stars, all posted in July 2026. One homeowner had put off basement leaks and chimney trouble over cost, got a quote they called affordable, and said the leaks held off through a later storm. Another, in a 112-year-old house with long-running water and damp, said the price came in well under other bids and the work finished in about a week. A third describes chimney and step repairs plus a new brick walkway. Two reviewers name Gerard as the person doing the work. One thing to weigh as you read them: two of those July accounts tell nearly the same story, down to the hesitation over cost and the storm afterwards. The company's own site describes an owner-operated shop — the founder grew up in his family's construction business and runs his own crew start to finish — working mostly on older New England brick and stone across Boston, Charlestown, Cambridge, Chelsea, Somerville, Allston, Quincy, Dedham, Braintree, Weymouth and Hingham. For a wet basement, a failing chimney or crumbling front steps on an older Boston-area house, this is a reasonable call to make: the state registration is current and the July jobs point the same direction. Ask for addresses of those jobs you can go and look at, get scope and price in writing, and confirm insurance — a few months of trading is what there is to judge them on.
Absolutely thrilled with the service from Three Hills Masonry! ⭐⭐⭐⭐⭐ I had persistent leaks in my basement and issues with my chimney that had been a concern for quite some time, but I was hesitant due to potential costs. A neighbor recommended this fantastic company, and after receiving a surprisingly affordable estimate for both repairs, I decided to go for it. The team was professional, friendly, and efficient. They completed the foundation repair and chimney work quickly, and after a recent storm, I can confidently say those leaks are a thing of the past! Their pricing was significantly lower than other masonry contractors, which is why I had delayed the repairs for so long. I wholeheartedly recommend Three Hills Masonry for any masonry work you need done. Great guys who truly deliver!
