Local Thornhill Crews Who Know the Area
Our teams service Thornhill every week and know its business districts — the Highway 407 corridor, Yonge Street, the Promenade shopping district, and the Markham and Vaughan business parks.

Serving Every Corner of Thornhill
Thornhill is a busy corner of York Region, anchored by the Highway 407 corridor, Yonge Street, the Promenade shopping district, and the Markham and Vaughan business parks. Companies here compete hard for staff and customers, and a clean, well-kept office space is part of that first impression. Whether you run a professional office near Thornhill Woods, a storefront in Royal Orchard, or a facility out toward German Mills, our team tailors a cleaning program to how your space is actually used.
A Dependable, Inspected Cleaning Program
Every Thornhill contract starts with a free walkthrough so we can price the work accurately and build a checklist around your priorities. From there a consistent, police-checked crew handles the day-to-day — dusting, disinfecting high-touch points, sanitizing and restocking washrooms, cleaning kitchens and breakrooms, vacuuming and mopping floors, and clearing trash and recycling. Supervisors inspect the work regularly so the standard never slips.
Commercial-Only Cleaning You Can Rely On
Because CMG Clean is a commercial-only cleaning company, everything we do in Thornhill is built for workplaces and business properties — never residential jobs. That focus means our staff are trained on office, retail, medical, and industrial environments across York Region, understand building-manager expectations, and keep the certificates of insurance and documentation your landlord may require on file.

Frequently Asked Questions
Common questions about office cleaning Thornhill.
How much does office cleaning cost in Thornhill?
There is no flat citywide rate — pricing for office cleaning in Thornhill depends on your square footage, how many areas are in scope, how often we visit, and the type of facility. A small professional suite near Thornhill Woods is a very different job than a multi-floor building off the 401. Tell us about your Thornhill space and we will provide a free, no-obligation quote with a clear flat rate.
Do you offer after-hours or overnight office cleaning in Thornhill?
Yes. Most Thornhill clients prefer evening, overnight, or weekend service so cleaning never interrupts the workday. We schedule around your operating hours across York Region and hold keys and alarm codes securely so your office space is cleaned and locked up without anyone on staff needing to stay late.
Which areas of Thornhill and York Region do you serve?
We cover all of Thornhill — including Thornhill Woods, Royal Orchard, German Mills, Uplands, Grandview, and Brownridge — and the surrounding York Region. If your office property sits anywhere near the Highway 407 corridor, Yonge Street, the Promenade shopping district, and the Markham and Vaughan business parks, our crews can reach it on a reliable schedule.
Are your Thornhill cleaners insured and WSIB-covered?
Yes. We carry commercial liability insurance and hold WSIB clearance for our Thornhill work, and every crew member is a police-checked CMG Clean employee. A certificate of insurance and a current clearance certificate come with our quote and are available on request.
How quickly can you start office cleaning in Thornhill?
After a quick walkthrough of your Thornhill site we can usually have a crew and checklist in place within a few business days. For urgent needs — a last-minute inspection, a new tenant move-in around Royal Orchard, or a same-week start — call 647-948-9415 and we will do our best to accommodate your timeline.
What does your office cleaning service in Thornhill include?
Our Thornhill office cleaning covers professional offices, medical and dental suites, retail plazas, and corporate suites along Yonge Street and Highway 7: dusting and surface wiping, high-touch disinfection, washroom sanitizing and restocking, kitchen and breakroom cleaning, vacuuming and floor care, glass and entrance cleaning, and trash and recycling removal.
