Janitronics

Janitronics Building Services is a commercial cleaning and building services company that maintains tens of millions of square feet for property managers, developers, multifamily owners and life science companies. Specialty cleaning for labs is a core strength: crews handle cleanrooms, GMP manufacturing areas and standard lab spaces for companies at every stage, from startups to full-scale manufacturers. The company has a large footprint in Cambridge, especially in Kendall Square.

Its roots go back to a small window-cleaning business founded in the 1920s, which became a full building services company in 1977. Today it is one of the largest locally owned janitorial companies in the Boston area, and many clients have stayed with it for more than 30 years. Services include commercial janitorial work, high-end day porter service, exterior cleaning, post-construction cleaning and emergency cleaning.
