SMS specializes in providing full housekeeping and maintenance programs to high traffic, public facilities throughout the nation, ranging from 300,000 to 1,500,000 square feet. That?s the technical answer, but what really defines us goes far beyond the work itself. At SMS we manage your services for you. We go beyond cleaning, beyond maintenance, and beyond any other company to make sure everything runs as smoothly as possible. Established in 1988, SMS is the foundation upon which all other SMS Holdings companies are built. It was through these ventures that SMS developed its approach to facility services management that has resulted in its current success.
