Local crews, local response.
Northwest Suburbs, IL.
Operating from Barrington with a tight Lake, Cook, and McHenry County footprint — so a same-day call-out is a phone call, not a logistics problem.

The questions facility managers ask first.
- What areas of Illinois do you serve? +
- Evergreen serves Barrington, Lake Zurich, Algonquin, Hawthorn Woods, Palatine, Inverness, Deer Park, South Barrington, Arlington Heights, Buffalo Grove, Schaumburg, Vernon Hills, Northbrook, and Elk Grove Village — generally a 20-mile radius around Barrington.
- Are your cleaning crews insured and background-checked? +
- Yes. Every team member is background-checked and W-2 employed. We carry general liability, janitorial bond, and workers' compensation, and we can provide a Certificate of Insurance on request.
- How quickly can you start service? +
- Most new accounts begin within 7–10 business days of a signed agreement. Urgent or post-construction one-time projects can usually be booked the same week.
- Do you clean after business hours? +
- Yes. The majority of our office and medical clients are serviced between 6pm and 6am. Day-porter programs cover daytime needs separately.
- How is pricing structured? +
- Quotes are flat-rate by visit, based on square footage, fixture count, and frequency. There are no per-supply surprises — everything is documented in the scope of work.
