About Us

Our dedication to our work and stubborn focus on solid surfaces has led to Sigma having immense knowledge and expertise in our field and the services we provide. We are not a janitorial service or an interior maintenance company for all types of surfaces, we only work with natural stone, and terrazzo finishes. Our clientele includes, prominent commercial developers, management companies and public institutions, as well as high-end residential. Sigma is a small minority owned business that prides itself on being able to provide a truly professional and pleasant service to our clients, where our only focus is making what you already have, its absolute best. Sigma Polishing started independent of Sigma Marble & Terrazzo in 1998, and with over 8,000 projects since then, Sigma Polishing has grown to establish itself as a leader within the natural stone and terrazzo restoration industry.
