    James and his crew did a good job on a chimney crown repair and new cap. Would use again.

    Good professional service! Coordination was easy, the Service team arrived on time. And the Team went above and beyond to secure a loose fixture on the roof for free! Thanks!

    I have a historical home in brookline, the chimney was falling apart and Keystone Masonry looked at it, provided the estimate and timeline. The completed the job beautifly and on time as promised. Very happy with their work

    Keystone Masonry fixed up our front walkway and stairs. They did a great job overall and when we identified a minor issue a few months later, James promptly followed up and had it fixed without any additional charge. We would definitely reach out to them again for future work.

    ⭐️⭐️⭐️⭐️⭐️ I recently had James come out to fix the columns that hold up my deck, and I couldn’t be happier with his work! He was professional, skilled, and took the time to make sure everything was done right. The deck feels solid and looks great now. James was on time, respectful, and clearly knows his craft. I’d definitely recommend him to anyone who needs masonry or structural work done. Very happy with the results—thank you, James!
