We have earned a reputation for quality work and excellent customer service primarily because of our experienced, knowledgeable and highly trained staff and crew.

Customers who choose Renaissance Stone Care & Waterproofing can be confident their property will receive the best and most appropriate waterproofing products available, and that they are applied by professionally trained applicators who adhere to the industry’s highest standards.

The experts at Renaissance Stone Care & Waterproofing are well versed in the latest industry technology and architectural trends. Architects and designers today are choosing stone to enhance the beauty and value of homes and businesses. The staff and crew of Renaissance Stone Care & Waterproofing are adept at the correct methods of maintaining each specific type of stone such as Travertine, Marble, Granite, Limestone, Slate or Terrazzo. Effective preservation not only reduces scratching and staining, it also enhances the beauty of the marble while imparting a more slip-and stain-resistant finish to new or existing stone installations. The staff and crew at Renaissance Stone Care & Waterproofing also offer effective restoration stone care services to help customers reclaim their investment in the beauty of precious dimensional stone. Restoration is the healing process that includes stripping away old wax and chemicals, repairing cracks and grouting, refinishing the stone to an even surface, removing scratches, stains, chips and pockmarks. And finally, polishing to achieve the fresh look of a factory finish.

Fully licensed and locally-owned, we earn our reputation one satisfied customer at a time.
