Bidding Commercial Pressure Washing Jobs: Square Footage, Equipment, and Margin
Commercial pressure washing bids run about $0.08 to $0.35 per square foot in US metros, and the spread comes from access, water, and equipment.
What to take away
- Commercial pressure washing bids in US metros land near $0.08 to $0.35 per square foot, with garages and warehouse slabs at the low end and storefronts or grease-heavy surfaces at the high end.
- The bid is not the wash price. It is labor hours, water and chemical, equipment allocation, insurance certificates, and a mobilization charge for the drive.
- Property managers in Phoenix and Atlanta usually ask for a certificate of insurance naming the owner as additional insured before they will look at the number.
- Margin disappears on travel, water hauling, and rework, not on the cleaning itself. Those three lines decide whether a commercial job pays.
- A written bid template that lists exclusions protects you more than a low price does.
What the range covers
A commercial pressure washing bid is a per-square-foot number that already has the fixed costs baked into it. The range below is illustrative for US commercial work in 2024 and 2025, drawn from published contractor pricing guides and bid sheets operators share in trade forums.
| Surface and setting | Low per sq ft | High per sq ft |
|---|---|---|
| Warehouse or parking garage slab | $0.08 | $0.15 |
| Sidewalk and loading dock | $0.10 | $0.20 |
| Storefront and entry pavers | $0.15 | $0.28 |
| Drive-through and dumpster pad | $0.20 | $0.35 |
A 40,000 sq ft garage at $0.10 is a $4,000 job. The same square footage of dumpster pads at $0.30 is $12,000, and it takes longer per foot. Square footage alone never sets the price.
Line by line
An invoice for commercial work usually breaks into these items.
- Labor
- crew hours at a loaded rate of $35 to $65 per hour, including payroll taxes and workers compensation.
- Water
- metered cost where a spigot is available, or $150 to $400 per tanker load where it is not.
- Chemical
- $0.01 to $0.04 per square foot for degreaser on grease-heavy surfaces.
- Equipment allocation
- a share of the machine's purchase price and maintenance, often $15 to $40 per operating hour.
- Mobilization
- $75 to $300 per trip for fuel, trailer, and setup time.
Insurance belongs in the overhead you spread across every bid, not as a line the client sees. General liability for a pressure washing operation commonly runs $1,200 to $4,000 a year depending on payroll and state.
What moves the number
Three drivers change a bid more than square footage does.
Access is the first. A garage with a working water source and drive-in lanes takes a fraction of the time of a downtown Atlanta loading dock that needs a permit, a lane closure, and a tanker. Crews that price both the same way lose money on the second.
Surface type is the second. Concrete slabs release dirt with a surface cleaner. Grease on a dumpster pad needs heat, dwell time, and a second pass. That is a different machine and a different chemical.
Frequency is the third. A quarterly contract at $0.12 per square foot beats a one-time job at $0.20 because you skip the sales cost and schedule the crew in a predictable block.
Roof and elevated work adds fall protection obligations under OSHA fall protection rules, and that gear and training time belong in the bid. Chemical mixing brings hazard communication duties under OSHA hazard communication requirements, which means safety data sheets on site and labels on every secondary container.
What quotes leave out
Most small operators underbid because they leave the same five things off the page. Water sourcing is one. Disposal of wash water is another, and some cities restrict what can enter a storm drain. Rework is a third: if the client walks the lot and finds stripes, you return for free.
Permits and lane closures are the fourth, and they can add hundreds of dollars in a downtown core. The fifth is the certificate of insurance. Property managers expect a COI naming them as additional insured, and buying it after you win the job eats the margin you quoted.
A bid template that lists exclusions in writing, signed before the crew rolls, is worth more than any pricing trick. If you want the residential version of that document first, see sample pressure washing quotes, which shows how the same line items look on a smaller job.
Where people overspend
Overspending on commercial bids rarely means paying too much for soap. It means buying equipment the job does not need yet. A $12,000 hot water trailer only pays if you have grease work booked most weeks. Until then, rent one for the dumpster pad jobs and keep the capital.
A machine that sits idle still costs money in depreciation, insurance, and storage. Bid the work you have, not the work you hope to have.
The second overspend is travel: crews chasing jobs two hours away at $0.10 per square foot often lose money after fuel and windshield time.
The third is staffing: hiring a second crew before contract volume supports it turns a profitable bid into a payroll problem. a training checklist for pressure washing staff matters before you scale.
Example: a Phoenix retail center
Take a 60,000 sq ft retail center with 45,000 sq ft of sidewalk and 15,000 sq ft of storefront pavers. Bid the sidewalk at $0.14 and the pavers at $0.22. That is $6,300 plus $3,300, or $9,600. Add $250 mobilization and $400 for a quarterly schedule discount, and you land near $9,450.
Cost side: two workers for 20 hours at $45 loaded is $1,800, water is metered at roughly $120, chemical runs $600, and equipment allocation at $25 per hour over 40 machine hours is $1,000. Insurance and overhead take another $1,500.
That leaves about $4,400 before taxes, a 46 percent gross margin. Drop the price to $0.10 per square foot, and the same job returns roughly $1,500, not enough to absorb one rework visit.
