Dave the Marble Guy

David Bonasera, better known as Dave the marble guy has been working with Natural stone including Marble, Limestone, Travertine, Onyx, Granite and all types of grouts and masonry surfaces.

Since 1987, when he started in Los Angeles,David's intense training for all  of his employees is done in the shop before we go out to any job site.  (we also train other company’s). Whether it is diamond grinding marble  floors, honing, or polishing your natural stone floors, counter tops, or shower walls back to a factory shine, we also stop leaks in your shower by the use of superior grouts that do not leak and are  mildew-resistant. Even if you get a new shower door and need the old  holes filled in and polished out as if they were never there.


Almost all of the products that David uses are also sold on-line at espsales.net and with the proper training and cleaning procedures all clients can  keep up their natural stone surfaces for years. That is why David has  called his main company ESP (Environmentally Safe Products and  Procedures) Lic # 508842

ESP specializes in complex repairs of Grout, Marble, Granite, Limestone and Travertine whether it is filling in holes in the stone, polishing marble or granite to a factory shine,. flattening a natural stone floor, or bonding the tiles back when they become loose. We also offer consulting and Expert Witness on jobs which have gone south from another contractor.

We Serve San Jose, Los Gatos, Saratoga, Campbell, Cupertino, Sunnyvale, Mt. View,  Los Altos, Palo Alto, Stanford, Menlo Park, Atherton, Portola Valley,  Woodside, and all of the San Mateo county areas.
