Priority One

What Priority One does

Priority 1 Janitorial Services (operating as Priority One) is a privately held, family-owned commercial cleaning company headquartered in Mundelein, Illinois, serving the Chicagoland metropolitan area. Founded in 1996, the company provides recurring janitorial services — daily, weekly, and monthly — for office and corporate spaces, alongside one-time specialty work including post-construction cleanup, flood and storm recovery, and emergency response. Service delivery is built around skilled in-house custodial crews using state-of-the-art cleaning equipment, with site-specific operational practices such as dedicated bathroom-only mops and buckets to prevent cross-contamination and on-stored equipment at larger facilities for rapid response.

The company operates six productized service categories: Office Cleaning (routine custodial maintenance), Commercial Cleaning (restaurants, retail, hotels, event venues), Floor Cleaning & Service (polishing, stripping, resealing, refinishing across all floor types), Specialty Cleaning (seasonal, post-event, post-construction, disaster recovery), Window Cleaning, and High Dusting. Each category is offered as a standalone service or bundled into recurring maintenance contracts. Customer segmentation spans eight verticals — office/corporate, hospitality, retail, manufacturing, fitness, government, sacred/religious, and educational — with no publicly named anchor accounts.

The business model is subscription-style recurring commercial services sold via a sales-led, direct-to-B2B motion. Pricing is custom and quote-based, driven by square footage, restroom count, flooring type, service frequency, and whether union labor is required; pricing is not publicly disclosed. Demand generation runs through the company website, content marketing (blog), email newsletter, and an online quote request form. Revenue, funding, and ownership structure beyond family-held private status are not disclosed.
