CentiMark Corporation opened its doors as a building maintenance and services company with a focus on flooring.


QuestMark, a division of CentiMark Corporation, was established to expand CentiMark’s presence in the commercial flooring industry.
DiamondQuest, an innovative technology for concrete grinding and polishing, launched QuestMark into the fast-growing commercial flooring segment. Its success led us to expand our offerings. Today, we install and service polished concrete, epoxy and secondary containment as well as provide floor repair and maintenance services.


QuestMark achieved over $100,000,000 in sales. This was accomplished through the organic expansion of flooring offices throughout the United States and Canada as well as through the additional product offerings we provided to meet the needs of the industries served.
Launched online flooring shop that offers a wide variety of do-it-yourself (DIY) flooring products, such as floor patch, coatings, and floor maintenance products, along with the tools and accessories needed to get the job done.


As a leader in the flooring coatings industry, QuestMark expanded product offerings with the launch of traffic solutions. Coatings for traffic solutions are engineered to last longer and are used to help preserve parking lots, decks and sidewalks.
