- Per-square-foot, hourly and flat monthly pricing are all common. They are just different ways to package the same labor.
- Hourly pricing is flexible but can be unpredictable. Flat monthly pricing is predictable but needs a precise scope.
- Whatever the model, ask for the labor hours behind the price.
Cleaning companies package their prices in a few different ways. None is automatically better. What matters is that you understand what you are paying for.
The four common models
1. Per square foot
The vendor sets a rate per square foot per month or per visit. It is easy to compare across buildings, but it hides important details: two buildings with equal size can need very different time depending on restrooms, flooring and clutter.
Best for: open, uniform spaces such as large offices.
2. Hourly
You pay for the hours worked. It is flexible and transparent, and good for irregular or one-time work. The risk is cost uncertainty, and slower work can cost more.
Best for: special projects, event cleanup and emergency work.
3. Flat monthly fee
One predictable price for a defined scope and schedule. It is simple for budgeting and aligns incentives, since the vendor is motivated to work efficiently.
Best for: recurring service with a stable scope. This is the most common model for ongoing commercial cleaning.
4. Per visit or per task
A price for each visit or each specific service, such as a carpet extraction. Good for add-ons.
How the models compare
| Model | Predictability | Flexibility | Best use |
|---|---|---|---|
| Per square foot | Medium | Low | Open spaces |
| Hourly | Low | High | Projects and one-offs |
| Flat monthly | High | Medium | Recurring service |
| Per visit | Medium | High | Add-ons |
The question to ask with every model
"How many labor hours does this price assume per visit?" The answer reveals what you are really buying. See how to evaluate bids.
Watch for hidden extras
Supplies, restroom restocking, trash haul-out, holiday visits and after-hours access are sometimes billed separately. Ask for them to be listed.
