About The Heiser Group

The Heiser Group is a janitorial services and industrial cleaning business based in Buffalo Grove, Illinois. Founded on May 5th, 1978, The Heiser Group is a family-owned and operated business in its third generation of “Heiser”.

Since the company’s inception, the Heiser family has implemented four key pillars that set us apart from the competition: Honesty, Integrity, Quality, & Service.

David’s grandfather and father believed that any company can clean a building, but going the extra mile can separate a normal janitorial company from a great one.

We pride ourselves on doing just that, offering commercial and residential cleaning with a personal touch.

“After major remodeling and renovation in our building, it was a disaster. David came in and assessed the situation and sent his two best guys. In one evening, they cleaned the inside of the building completely. ”
