When you look at the granite or marble surfaces in your home, do you wish they looked cleaner and brighter?

Though regular home cleaning on your own does help maintain your stone surfaces, it’s tough to keep your stone surfaces 100% clean with so much built-up residue over time. If you’re looking for a professional cleaning company that can break through this tough residue to revive and restore your granite, give us a call at COIT stone cleaning Modesto.

Here’s a quick list of stone surfaces we treat: marble, granite, slate, Saltillo, terrazzo, travertine and more. Essentially, if it’s made of stone, we can clean it.

Experience Our 5-Step Cleaning Process that Revives Your Natural Stone Surfaces

Step 1: First, we’ll prepare your stone surfaces by blocking off any areas that won’t be treated.

Step 2: If needed, we’ll then pre-seal the surface to ensure it’s as dry as possible before we start deep cleaning.

Step 3: Next, we’ll hone the stone surface using cleaning agents and grease cutters that can break through tough residue. Through honing the surface, we can get rid of scratches, too.

Step 4: Using powerful equipment, we’ll then polish the stone surface to bring back its natural shine.

Step 5: Finally, we’ll seal the stone surface to create a protective layer between treatments.
