And ESP has been stopping leaks in showers for over 23 years now.


Our unique take on tile and stone restoration to provide environmentally safe products and procedures stem from our owner, David Bonasera’s background. David started his experience in environmental issues back in the late 80’s and early 90’s in the west side of Los Angeles and Orange County areas by doing stone work and environmental indoor air quality inspection. (David was one of the top indoor air quality inspectors in Southern California). During that time David also studied the geological properties of stone to determine why and how installation should be done and how to fix the stone or tile that has been installed incorrectly, coming up with procedures to refinish and protect natural tile and stone.


David’s experience and passion for stone has brought him to not only to be a national speaker as a tile and stone consultant, he is also an investigator and volunteer at the Cal State board of contractors with others writing the test for the C-54 test (Tile, stone and fabrication areas).

In addition his way of doing business comes from his extensive background in touring and building large rock n roll productions. During his years in entertainment David was a Rodie, lighting designer and ran four departments for the largest light touring company in the world. The work ethic of ”the show must go on” and always be prepared for anything has transferred to complete the job on time and as promised plus always keep your supplies stocked.


Our team at ESP’s goal is to not to go fast but to do the job right and then we make sure that the client can call for any information or concerns.

ESP sells many line of fine quality environmentally safe products: Stone Pro, Magic Al, Bonstone and Touch stone adhesives, MORE stone care products, Easy Care Products, and Better Bio which is over 80% bio based and approved by the USDA. So you might say that David Bonasera and ESP are still 5 years ahead of green.
