Yonkers is a brick-and-bluestone city — mill brick down in the hollow, stone steps and retaining walls on every hill. Snow treats stone badly: it melts by noon in a February thaw, runs down the risers, and freezes to glass by six. Junior's masonry & landscape inc clears it the thorough way — plowing drives and lots, shoveling stairs and walks down to the surface, salting the places where runoff always goes. Clean stone dries; half-cleared stone stays a hazard for a week. That difference is what the work is aiming at.
