Pressure washing
Commercial Pressure Washing Cost Calculator
Prices commercial washing, where capturing the wash water is part of the job.
Result
A planning estimate, not a quote. Access, the age of the equipment, what is found once it is opened up and local labour rates all move the real figure, sometimes a long way.

Hours times crew times rate, plus chemicals, disposal and the call-out, by area. Commercial work is priced like residential with three additions: it usually happens outside trading hours, the areas are large enough that equipment productivity dominates, and the wash water frequently has to be contained and disposed of rather than allowed to run off. That last item is a real cost involving berms or mats, a vacuum recovery system and tankered disposal, and it is what separates a compliant commercial operator from a cheap quote.
What moves the number
- Whether wash water has to be contained and recovered, which is a major cost.
- Out of hours working, which is usually required and carries a premium.
- Area and equipment productivity, since scale rewards better machinery.
- Site requirements such as insurance certificates and induction.
Where this one goes wrong
Wash water from commercial surfaces carries oil, grease, detergents and sediment, and discharging that into a storm drain is regulated in many jurisdictions because storm drains generally run to waterways untreated. Containment, recovery and proper disposal are the compliant approach, and enforcement is real: fines fall on the contractor and sometimes the property owner. A competitor quoting significantly lower is frequently not containing anything, which is worth being able to explain to a client. Site paperwork is the other practical gate, since many commercial properties require a certificate of insurance and an induction before anyone works there.
Before you quote
- Establish local requirements for wash water containment and disposal.
- Price recovery equipment and disposal rather than omitting it.
- Obtain site insurance certificates and inductions ahead of the date.

Questions
About this calculator
Can wash water just run into the storm drain?
In many jurisdictions no, because storm drains generally discharge to waterways without treatment, and commercial wash water carries oil, grease, detergents and sediment. Containment, recovery and proper disposal are the compliant approach, and enforcement with fines is real for both contractor and property owner.
Why is one commercial quote so much lower?
Frequently because it does not include wash water containment and disposal, which is a genuine cost involving berms, recovery equipment and tankered disposal. It is worth asking directly how runoff will be handled, since the liability can reach the property owner as well as the contractor.
Does commercial washing have to be done at night?
Usually, because large paved areas and building faces cannot be cleaned around customers, deliveries and parked vehicles. Many sites also restrict the hours. That carries a rate premium but it is normally unavoidable rather than a preference.
The formula
total = hours x people x rate + parts + call-out, then sales tax

A worked example
These are the figures the calculator opens with. Every number in the results column below is produced by the same calculation the page runs, so you can follow it through before putting your own figures in.
What goes in
| Input | Value |
|---|---|
| Hours on site | 3 h |
| People needed | 1 |
| Labour rate charged | $95 |
| Parts and materials | $35 |
| Call-out or diagnostic fee | $95 |
| Sales tax | 0% |
What comes out
| Result | Value |
|---|---|
| Estimated total main result | $415 |
| Labour | $285 |
| Before tax | $415 |
| Sales tax | $0 |
About $415: $285 of labour, $35 of parts and a $95 call-out.
How sensitive the answer is
Holding everything else steady and changing only labour rate charged, this is what happens to estimated total. It is worth knowing which of your inputs the answer actually hinges on, and which barely move it.
| Labour rate charged ($) | Estimated total |
|---|---|
| $48 | $274 |
| $71 | $343 |
| $95 example above | $415 |
| $143 | $559 |
| $190 | $700 |
Every other input is held at the example value while this one changes, which is not how a real job behaves. Treat it as a guide to which number matters most, not as five separate quotes.
