About Onyx Surface Coatings

Built by Family.
Built to Last.

A family-owned flooring and concrete coating company built on honest work and proper preparation — serving Denver, CO and surrounding areas from Denver, CO.

Our Story

Onyx Surface Coatings was started after noticing a lack of high-quality, dependable contractors in the local area. Too many floors were being rushed or improperly prepared, leaving homeowners and businesses with coatings that failed long before their time.

William operates the company together with his two sons — a true family business. Together they set out to do flooring differently: honest work, clear communication, quality craftsmanship, proper preparation, dependable service, and a genuine commitment to serving the local community.
