Illinois standards for DeKalb facilities
DeKalb employers in manufacturing, distribution, healthcare, and corporate offices need a facility partner who treats clean as part of operations, not an afterthought. Optimal delivers nightly janitorial, hard-floor and carpet care, restroom sanitation, disinfection, and day-porter coverage — scoped to your building and your hours.
Then there is the weather. Illinois’s long, snowy winters drag salt, slush, and grit across your floors for months, and entrances take the worst of it. Our DeKalb scope includes matting programs, daily hard-floor care, and ice and snow response so your lobby does not become a slip-and-fall claim mid-winter.
One DeKalb account, one regional team, one report. From a single office or clinic to a multi-site footprint across the surrounding area, you get the same standard and the same proof at every location.
