Many Portland homeowners incorporate natural stone surfaces into their décor. These beautiful stone surfaces deserve the best professional care. COIT Portland's high-quality, proven stone cleaning process offers just that. Our experienced technicians are available to visit any home in the Portland area, and to complete a detailed inspection of the stone surfaces. After inspecting your home, they will recommend the best overall cleaning process for the houses' natural stone.

For many stone surfaces, the cleaning process involves most, or all, of the following steps:

  • Preparation and pre-cleaning, including masking of non-treatment areas.
  • Pre-sealing to maintain a dry surface.
  • Honing - Using a laboratory-developed and field-tested combination of abrasive compounds, cleaning agents and grease cutters, the stone surface is gently honed to remove scratches, etches, and wear marks.
  • Polishing - After a thorough rinse, special machinery and compounds bring the original shine back to treated stone surfaces.
  • Sealing - One or more coats of special sealant are applied and buffed to protect against future staining.
