Slate Cleaning in NYC | Natural Stone Restoration | D’Sapone

Slate cleaning the safe way.

Slate stone comes with all the crevices, allowing stains to seep deep into the surface. Our quality slate cleaning in NYC releases all the stains, mold and mildew with an incredible cleaner, penetrating deep to bring cleanliness at every level. We can make your unsighted stone look new again.

Slate shower. Sanitizing.

It can be very tricky to clean slate showers as mold, mildew and soap scum continuously attack the stone. We will clean, sanitize and prep your slate with the most powerful cleaner, releasing all the deep mold and stains. We carry a 5 year labor warranty on our ‘Healthy Shower’ service.

Sealing. After slate cleaning.

Slate must be sealed once it has been cleaned as it is very porous and continuously releases dust in dry settings, while it allows the passage of liquids or moisture in wet settings. Our clear topical sealing process with Celine prevents the stone from releasing dust and retaining liquids while creating a waterproofed surface. Celine is the most powerful slate sealer, keeping the surface sanitized with a refined elegance.

Grout sealing.
After cleaning the slate.

Our slate cleaning in NYC is followed by a grout sealing process. Just like slate, grout also allows the passage of moisture easily that causes mold and stains. Color sealing the grout with Caponi® – a two part pigmented titanium epoxy/resin eliminates this issue permanently. It locks out all the stains while soaking into the grout with 100% color uniformity.
