Perfect Building Maintenance (now a division of PBM, LLC) was founded in 1923 by Austrian immigrant David Mager. When he arrived in New York City, Mager took the best job he could find — washing windows in Brooklyn. Mager distinguished himself by providing exceptional customer service, and his success soon enabled him to move to Manhattan and start his own cleaning company. Given his hard-earned reputation and high standard of work, he called his company Perfect Building Maintenance.
The company flourished. Eventually Mager’s sons, Norman, Marvin and Lawrence, took over, continuing their father’s philosophy of quality service and unstinting personal attention. Today, Norman’s son, Scott Mager, represents the third generation of Magers to run PBM.
