    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.

    The foundation in our basement was showing signs of movement. Their repair work stabilized it completely.

    ⭐️⭐️⭐️⭐️⭐️ 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!

    I met James from Keystonemasonry with the expectation that I would have my front stairs repaired. What I soon found out the my stairs were way worse than I thought. I had a safety issue along with looking very bad. James came up with a fair budget and the team went to work. A team of mostly three re-built my stairs. Straight, neat, and done in three days. I made a great decision going with Keystone Masonry, and will not hesitate to use them again. Also, the cleanup after a giant pile of brick and cement was outstanding.
