Office cleaning in Markham
Markham’s offices range from corporate and technology offices along Highway 7 and the 404 and 407 corridor to multi-tenant buildings in Markham Centre, clinics and professional suites in the plazas, and offices at the front of business-park units. Whichever yours is, we clean it after hours, by the same crew each visit, from a written scope agreed at a free walkthrough.
A routine visit covers open-plan floors and workstations, kitchens, meeting rooms, washrooms, glass and the touch points everyone shares, every night, a few evenings a week or weekly, with carpet and floor care planned through the year. See office cleaning for the full scope.
A campus or a multi-tenant floor can be priced per tenant or as one scope; the pricing guide covers both, and the frequency guide helps split daily from weekly work.
Working in Markham
Markham’s commercial space runs along Highway 7 and the Highway 404 and 407 corridors. We cover:
- Markham Centre around Highway 7 and Warden Avenue
- The Highway 404 and 407 office and technology corridor
- Unionville and the Highway 7 East corridor
- The Steeles Avenue and Woodbine Avenue business areas
- The Markham Road (Highway 48) corridor
The buildings, and what they need
- Technology and corporate offices. Low-rise office buildings and campuses with open-plan floors, kitchens and meeting rooms, cleaned after hours on a recurring schedule.
- Business parks with office and warehouse. Units with offices at the front and storage or light assembly at the back, where the two halves need different care: janitorial for the office, floor scrubbing for the back.
- Clinics and professional offices. Medical, dental and professional suites in plazas and small office buildings, which need to be ready before the first appointment of the day.
Getting there and scheduling
The route to Markham is the Don Valley Parkway and Highway 404, 30 to 40 km north-east of downtown and around 35 to 50 minutes in the evening.
Markham contracts run on fixed evenings agreed at the walkthrough, with the office side and any warehouse side scheduled separately if they need to be.
Where we work from
We do not have an office in Markham: crews travel from our Toronto base at 243 Queen St W in Toronto.

Yes. Markham Centre, the Highway 7 corridor and the business parks along Highway 404 and 407 are all in our service area, and offices there are cleaned after hours.

Yes. They go into one written scope, with recurring cleaning for the office side and scheduled floor care for the back.
Can our clinic be cleaned after the last patient?
Yes. Clinics are cleaned in the evening so treatment rooms, waiting areas and washrooms are ready for the morning.
