Our Team

Mark Fetters

Mark started his career as a sales representative for many different companies including chemicals sales in the commercial cleaning industry. Seeing new trends in the concrete and stone flooring industry, he decided to specialize in sealing, polishing and coating products designed for the next generation. After working on some of the largest concrete flooring projects in Idaho, he decided to expand his knowledge in the stone restoration industry. After being trained by the best-known stone restorer and forensic scientist in the world, Mark decided he had enough experience and knowledge to evaluate stone problems and solve them. He first started in the cleaning of stone then went off to polishing. Today, with over 25 years in the business solving stone problems, he is always looking for a new challenge. Today, he is now training his son Mack, the same techniques and trade secrets that can only be taught by working very closely with each other.

Mack Fetters

Every day brings a different stone problem and a different solution. Growing up working with his dad on jobs during his high school years, Mack decided after graduating from high school that this trade was unique and different. He decided to follow his dads’ footsteps and go to stone polishing school and to work side-by-side with his father. Today, the father and son team have many successful projects under their belt. Currently, they average several hundred stone problems a year locally and throughout surrounding states. Mark currently is a consultant in the industry and managing the business. Mack spends most of his time running the daily projects and taking on new challenges. Now, that’s experience!
