Stone Masters Inc in Chula Vista's Third Avenue Village district has restored natural stone surfaces throughout San Diego County since 2010, operating from 157 F Street in the 91910 zip code. When honing and polishing cannot recover a severely cracked or spalled marble floor, the firm refers clients to tile-installation contractors such as Quality Design Tile & Stone for full replacement with matched material. The company's service menu covers diamond-abrasive honing, crystallization polishing, lippage removal, crack and chip repair, and penetrating-sealer application on marble, travertine, limestone, slate, and granite. Commercial clients along the Broadway corridor and in the Otay Ranch Town Center area that maintain stone lobby floors on quarterly schedules often bundle those visits with deep carpet extraction from Hot Style Carpet Cleaning for a single-day floor-care turnaround. The firm's highest-tier restoration projects involve multi-pass diamond grinding at 50, 100, 200, 400, 800, and 1500 grit to remove etching and lippage from Carrara or Calacatta marble slabs before applying an impregnating fluoropolymer sealer.
