Limestone Cleaning, Honing & Polishing Services

Limestone is soft and porous, and it etches easily, which is why so many Chicago floors turn dull or stained within a few years. Our limestone restoration for Chicago homes starts by determining whether the damage is surface-level or has penetrated the stone, since that changes the entire approach. Light dulling gets a pH-balanced limestone cleaning across Chicago, safe for porous stone. Etched or scratched spots are addressed through honing to level out the damage, and then a final polish restores the shine. Neglected floors often need crack filling first under our limestone tile restoration work in Chicago buildings.

Common questions about limestone restoration

Can dull or etched limestone be polished again?

Yes. Etching and dullness sit in the top layer of the stone, so limestone tile restoration in Chicago removes them by honing with progressively finer diamonds and then refining to the sheen you want. Deep etch rings from acids may need extra passes, but the stone itself does not need replacing.

Does limestone need to be sealed after cleaning?

Yes. Limestone is highly absorbent, so after limestone cleaning in Chicago we apply a penetrating impregnating sealer that sits below the surface and slows staining from water, oil and wine. Sealer does not stop etching from acids, so we also explain which everyday cleaners are safe to use on your stone.

Why does limestone stain so easily?

Limestone is soft and very absorbent, so oils, red wine, and rust marks soak in quickly. We use poultices to draw stains out of the stone, then hone the surface and apply an impregnating sealer to slow future absorption.

Can scratches be removed from limestone floors?

Yes. Scratches and traffic patterns are honed out with progressively finer diamond abrasives until the surface is uniform again. The result is a smooth, even finish without replacing tiles.

How often should limestone be sealed?

Limestone floors and showers typically need resealing every one to two years, and sooner in high-traffic entries or steam showers. We can set you up on a maintenance schedule so the stone never reaches the stained, worn stage.
