About Legacy Glass Block & Window Co.
We started in 1986 with one goal — do precise work for our neighbors.
Four decades later, the job hasn't changed. Careful craftsmanship, and close attention to the structural health of every home we work on.
We're family-owned and operated. We treat your house the way we'd want ours treated.
Our family also runs Legacy Fresh Coat Painting, handling interior and exterior painting across the same service area.
