Coming soon to the App StoreHow pressure washing pricing works
Square footage × production rate = hours
Every surface has a realistic pace: concrete flatwork washes fast, wood decks and stucco are slow, careful work. Measure the area, divide by your rate for that surface, and you have the honest core of the price. Guessing hours without measuring is where most bad quotes start.
Condition and access are multipliers, not footnotes
Heavy buildup, organic growth, tight access, and second-story work don't add a few minutes — they multiply the whole job. A driveway with oil staining can take half again as long as the same driveway with light dirt. Quote the surface you actually saw, not the best case.
Setup time is real time
Unloading, hose runs, connecting water, protecting plants and fixtures, repositioning between zones, packing up — on a small job, setup can rival washing time. That's exactly why minimum charges exist.
Set a minimum charge and let it do its job
A minimum job charge covers the cost of simply showing up: travel, setup, teardown, and a baseline profit. Price every job normally, then let the minimum quietly catch the small ones. The calculator shows you when the minimum — not the math — is setting the price.
Chemicals, water, and equipment are job costs
Pre-treatments, surfactants, water you supply, fuel for the machine, and wear on pumps and nozzles all belong in the job's cost — not silently absorbed. Operators who skip these costs underprice by the exact amount they forgot.
Overhead and profit close the loop
Insurance, the trailer, the website, your phone — every wash has to carry a share. Add overhead to direct costs, then price for the margin you actually want. Covering costs isn't profit; it's break-even with extra steps.
Safety and accuracy notes
Different materials need different pressure and treatment methods — always test an inconspicuous area first. Roof cleaning is typically a soft-wash service, not high-pressure washing, and deserves its own assessment. Specialty stains (oil, rust, irrigation) may need separate evaluation, and results can't be guaranteed. This calculator estimates pricing only — not treatment methods — so follow your equipment, chemical, runoff, and local safety requirements.
A note on taxes
Exterior cleaning services are taxable in some places and not in others. The calculator can add tax on top of your pre-tax price, but check your local rules with a tax professional.
Five jobs, five different prices
Same calculator, different surfaces — this is why one flat rate for everything leaks money.
Driveway
Fast production rate, one setup zone. Small ones often hit your minimum charge — that's the minimum doing its job.
House siding
Slower rate, second-story multiplier, more masking and care. Height changes this job more than area does.
Deck / patio
Wood needs lower pressure and patience — the slowest residential rate, often with sensitive-surface care.
Fence
Two sides, awkward access along the line. Linear jobs hide more square footage than customers expect.
Commercial walkway
High production rate but multiple setup zones and scheduling constraints. Setup time drives the quote.
Pricing a different trade? The service price calculator handles the general case, and the pressure washing page shows how operators run the whole workflow. The hourly rate calculator works out what your hour needs to earn. And the profit margin calculator converts margin and markup instantly.

Frequently asked questions
Is the pressure washing cost calculator free?
Yes. The calculator is completely free, with no sign-up and no limit on how many jobs you price.
Is my pricing data stored?
No. Everything you enter stays in your browser. Nothing is sent to or stored on our servers, and the numbers are gone when you leave the page.
How do I estimate pressure washing time?
Divide the square footage by a production rate for that surface — concrete flatwork washes much faster than wood decks or siding — then adjust for condition, access, and height, and add setup time. This calculator does exactly that with editable production rates.
Should I charge by square foot or flat rate?
Most residential quotes end up flat, but a good flat price is built from square footage times a realistic production rate. This calculator gives you both views of the same number, plus the effective hourly rate behind them.
How should I set a minimum charge?
Add up what it costs just to show up — travel, setup, teardown, and a base amount of profit — and never price a job below it. Enter your minimum in the calculator and it will hold the recommended price at that floor, telling you when it's the minimum that's controlling the result.
How do surface type and condition affect price?
They change the hours. A driveway with light dirt washes fast; stucco with organic growth is slow, careful work. The calculator uses per-surface production rates and condition multipliers you can inspect and edit.
How do I price a two-story house?
Height adds time and care — ladder or extension work, more setup, slower coverage. The calculator applies a story multiplier on top of the base rate; adjust it to how you actually work.
Should chemicals and equipment be separate costs?
Yes. Track chemicals, water you supply, equipment usage, and surface protection as their own line costs so every job pays for what it consumed — not just labor.
How do add-ons affect the estimate?
Each add-on contributes its own minutes and, where relevant, material cost — pre-treatment, oil or rust treatment, gutter exteriors, window rinse. Tick them and the time and cost are added to the job.
Should I charge sales tax?
Pressure washing is taxable in some places and not in others. The calculator can add tax on top of your pre-tax price, but check your local rules with a tax professional.
Can I turn the result into an estimate?
Yes. Put the price on a professional PDF with our free estimate generator, or save the service in the Revenuor app for iPhone and iPad and reuse it in every estimate and invoice.
Can I use this for roof cleaning?
The calculator includes a roof soft wash surface with its own slower production assumption, but roof work is a distinct, higher-risk service that usually uses soft-wash methods rather than high pressure. Assess each roof separately and price it as its own job.
Is this the same as power washing?
The terms are used interchangeably in most markets — power washing sometimes refers to heated water. Either way, the pricing model is the same: surface, area, condition, access, time, costs, and margin.
