Stone in Nassau County
What Nassau County owners usually need
Nassau County is the older, denser half of Long Island. Many of its homes were built decades ago, and a good number have marble or other natural stone in the places people notice first: the front foyer, a hallway, a bathroom floor or a vanity top. Stone that has been walked on for years tends to go dull in the main paths, pick up scratches, and show etch marks where something acidic was spilled.
Foyers, bathrooms and kitchens
In a closely built neighborhood, a single small floor is a common job. A foyer or a powder room is a modest area, so the question is usually whether honing and polishing will bring the surface back, or whether the floor also needs its grout cleaned and the stone sealed. Photos help when you call or text. Our marble restoration page explains honing, polishing and crystallizing.
Condos, co-ops and small commercial spaces
Along with houses, Nassau has condo and co-op buildings and a lot of small commercial space, such as offices and storefronts, where a lobby or entry floor is the first thing visitors see. If the stone is in a shared area, check with your building manager about their rules for outside contractors before you book anything.
Patios, steps and pavers
Outdoor stone gets weather and foot traffic all year. Dirty pavers, patios and brick are a pressure washing job, while interior travertine and terrazzo are covered on our natural stone restoration page.
