Bluestone Bluestone is a dense natural sandstone widely used for sidewalks, entryways, steps, and patios. It is valued for its durability, slip resistance, and distinctive blue-gray appearance.
Bluestone has long been used throughout NYC, particularly around historic properties and high-end residential or commercial buildings. It withstands heavy pedestrian traffic while providing a classic appearance that complements traditional architecture. Replacement or repair work often requires matching the existing stone in size, thickness, and finish.
