Our Clients Say.

***** (five stars) – Loved it!  “Hire them! The team at JM Masonry is just awesome.  They worked with us to re-engineer what turned out to be a major structural issue in our walk-out basement.  The masons were hard-working and skilled, as well as considerate and friendly. The management was excellent, communicating fully and problem-solving with us along the way.  We also hired them to do stonework repair on our fireplace mantle, which required special matching of stone. We are so pleased with and grateful for their work.”
