“How much does commercial cleaning cost?” is one of the first questions any Melbourne business asks — and one of the hardest to answer with a single number. Genuine quotes vary widely because several real factors change the price, not because pricing is deliberately vague. Here’s what actually drives the cost, so you know what you’re paying for before you compare quotes.
The factors that matter most
1. Square metreage and layout
Larger spaces cost more to clean, but layout matters almost as much as size. An open-plan office cleans faster per square metre than the same area split into many small offices, meeting rooms, and corridors — more doors, corners, and furniture to work around adds time regardless of total floor area.
2. Cleaning frequency
Daily cleaning costs more per visit than weekly cleaning, but often costs less per clean overall — a space maintained daily needs less intensive work each time than one that’s built up a week of mess. Frequency should match your actual foot traffic, not just budget (a guide to figuring this out is on our blog: how often should a Melbourne office be professionally cleaned).
3. Type of facility
A standard office costs less to clean than a medical clinic or a bar. Medical facilities need TGA-approved disinfectants, specific dwell times, and cross-contamination protocols — genuinely more time and higher-cost products than a general office wipe-down. Bars and pubs often need after-hours scheduling, which can carry a premium over standard daytime hours.
4. Access and scheduling constraints
After-hours or early-morning cleaning (common for hospitality venues and some corporate offices) sometimes costs more than standard business-hours cleaning, since it requires staff availability outside normal shifts. Restricted building access (security clearances, limited elevator access, shared-tenancy buildings with strict rules) can also add time and cost.
5. Specialized services
Regular cleaning is one price; specialized add-ons are another. Carpet steam cleaning, window cleaning, strip-and-seal floor treatments, and grease trap cleaning are usually quoted separately from your base contract, since they’re needed monthly or quarterly rather than every visit.
6. Staffing model
This is the factor most businesses don’t think to ask about, but it affects both price and quality. A provider using rotating subcontracted staff can sometimes quote lower, but consistency suffers — different people, different standards, every visit. A provider with dedicated, directly-employed, police-checked staff typically costs a bit more but delivers more consistent results and real accountability.
What a fair quote should include
A genuine, transparent quote should specify:
- Exact scope (which areas, how often)
- Whether staff are directly employed or subcontracted
- Insurance coverage (ask for the certificate of currency)
- What’s included in the base price versus billed as an add-on
Be cautious of a quote that’s dramatically lower than others for the same scope — it’s usually a sign of subcontracted, rotating staff or corners being cut on insurance and screening, not a genuine efficiency advantage.
Getting an accurate number
The only way to get a genuinely accurate quote is an on-site walkthrough — your actual foot traffic, layout, and specific requirements determine the real cost far more than a generic price-per-square-metre calculator ever will.
