The parts of Markham we clean most
Markham work is mostly recurring head-office and medical-building contracts. Corporate campuses typically require a certificate of insurance and an access arrangement before a contractor can start, so settle both with your facilities team ahead of the first visit.
What we clean in Markham, and how the spec changes
A quote is only comparable once scope and frequency match. These are the building types that drive commercial demand locally, and what each one actually needs.
Markham has more than 1,500 technology and life sciences companies, so much of the commercial demand is recurring head-office cleaning. Open-plan floors, shared kitchens, meeting rooms and washrooms on nightly or several-nights-a-week schedules, with equipment areas dusted but never opened.
Medical and dental tenancies need a documented disinfection routine, correct product dwell times and clear separation of clinical and waiting areas. See our medical office cleaning services for how that scope differs from standard office cleaning.
Storefronts and restaurants need entrance glass, floors and washrooms held to a visible standard. Older heritage-district buildings often have limited back-of-house access, so the schedule and equipment are planned around the building.
Lobbies, shared washrooms, corridors and elevator banks cleaned on a nightly schedule and coordinated with property management, building access rules and insurance requirements.
How commercial cleaning is scheduled in Markham
Most Markham contracts run in the evening or early morning, outside office and clinic hours. Hybrid work has changed occupancy on many tech floors, so the useful question at the walkthrough is how many people are actually in the space on which days, not what the lease says. Frequency is the biggest cost lever, and matching it to real occupancy usually matters more than the rate itself.
The scope per visit is written down and does not drift: workstations and shared surfaces wiped, washrooms cleaned and restocked with your supplies, kitchenettes and lunchrooms cleaned, floors vacuumed and mopped, high-touch points disinfected, and garbage and recycling removed. Periodic items such as glass and floor care are listed with their own frequency.
For a look at the building types and access rules by district, read our business cleaning guide for the Markham tech corridor and Main Street. Our GTA frequency standards explain how often different building types usually need service.

Comparing commercial quotes in Markham
Two contractors can quote the same building and land far apart. The difference is almost always buried in scope and frequency rather than in rate. Before comparing any two numbers, get these in writing.
A monthly figure means nothing on its own. Ask for the task list per visit and the frequency of each task. Vacuuming might be nightly while glass is monthly and floor care quarterly.
Most buildings do not need five nights a week. Auditing actual occupancy before renewing saves more than negotiating the rate ever will, particularly with hybrid schedules.
Hand soap, paper towel, toilet tissue and bin liners are the classic hidden cost. Confirm whether they are supplied or billed separately.
Ask for a certificate of insurance and confirm WSIB coverage. Then ask whether cleaners are employees or subcontractors: turnover is the biggest predictor of quality drift.
Our commercial cleaning frequency standards for the GTA breaks the decision down by building type.
Common questions from Markham facility and office managers
How is a commercial cleaning quote prepared in Markham?↓
We start with a free walkthrough of the space: cleanable area, washroom count, floor types, access rules and the hours the building is quiet. From that we agree a scope and frequency per visit and send an itemized proposal. No figure is quoted before the walkthrough, because two buildings of the same size can need very different scopes. You can also use the cleaning cost calculator for a first estimate.
Can you clean Markham offices after hours?↓
Yes, and it is the default. Evening and overnight visits keep staff, clients and tenants undisturbed. We agree building access, alarm procedures and any concierge or security sign-in with your facilities team or property manager before the first visit.
Are your cleaners insured and background checked?↓
Every cleaner is background checked and trained before being assigned to a commercial site, and we are fully insured with $4 million liability insurance and carry WSIB coverage. We provide certificates directly to your property manager or facilities team on request.
Do you provide day porter service in Markham?↓
Yes. Day porter coverage keeps washrooms, entrances and shared areas presentable during trading or office hours, alongside an overnight clean. We scope the two separately so you can adjust each one as traffic changes.
Do you clean tech offices and corporate campuses in Markham?↓
Yes. Corporate and tech offices are a large share of our Markham work, cleaned after hours with a consistent crew. We provide insurance certificates and agree access arrangements with your facilities team in advance.
Do you clean medical buildings in Markham?↓
Yes. Clinical areas follow a documented disinfection routine, kept separate from waiting rooms and offices. See our medical office cleaning services page for the scope.
Can you clean Main Street and Unionville storefronts?↓
Yes. We plan around limited back-of-house access, shared walls and entrance glass, and can combine an overnight clean with day porter coverage where foot traffic justifies it.
