A Scarborough-Based Cleaning Company Serving Markham

If you are looking for a cleaning company in Markham, it helps to know where we are. CMG Clean's office is at 10 Milner Business Ct in Scarborough, south of Steeles Avenue and a short drive from Markham along Markham Road, Kennedy Road, or Highway 404. We do not have a Markham office; our crews and supervisors travel to Markham sites from Scarborough and work to the same checklists and inspection routine as every other contract.
