If you've just started a pressure washing business and every quote feels like a guess, this guide walks you through the same pricing model that established exterior-cleaning companies use. You'll learn the per-square-foot rate-card formula, see worked examples for three real job types, and avoid the four pricing mistakes that quietly kill margin in your first year.
New pressure washing operators tend to do one of two things when a customer asks "how much?":
Both feel safe and both quietly cost you money. Quoting from memory means you'll forget the chemical cost on a heavy roof, undercount the square footage of a wraparound driveway, or miss that the north side of the house is solid algae. Quoting "what sounds reasonable" means you're guessing at margins you've never actually measured, with fuel, sodium hypochlorite, and equipment wear coming straight out of your pocket.
The fix is a repeatable formula. Once you have one, every quote takes two minutes, and the customer hears confidence in your voice instead of hesitation.
Pressure washing businesses generally use one of two approaches:
You quote a price per square foot of the surface, by surface type and method. Good for the bulk of residential and commercial work (driveways, siding, roofs, flatwork) where you can measure the area. The customer knows the price up front, and the risk lives with you if you measured wrong.
You quote an hourly rate or a day rate (often with a minimum). Good for unpredictable jobs: heavy industrial degreasing, graffiti removal, or anything where you genuinely can't estimate how long it will take. The risk lives with the customer.
Most successful pressure washing businesses quote a flat per-square-foot price built from an internal rate card. You price the area by surface and method, then present one flat number. That's the rate-card method.
This is the core formula used across the exterior-cleaning industry:
Six inputs drive everything: your baseline rate per square foot, your surface-method multipliers, your minimum, your chemical & consumables %, your markup %, and your access fees. Set those once, then every job follows.
For US exterior cleaning, typical published ranges by surface are:
New operators in lower-cost markets often start near the bottom of each range. Established crews with commercial accounts and the right equipment charge toward the top. Track your actual production after your first 5 jobs and adjust.
Rather than memorize five separate price lists, set one baseline flatwork rate and apply a multiplier per surface and method:
This protects you from quoting tiny jobs for a few dollars. For most pressure washing operators, a $175–$250 minimum is reasonable. It covers your drive, your setup and breakdown, your water and chemical, and the simple fact that getting a rig to a site has fixed overhead regardless of how small the surface is.
Sodium hypochlorite, surfactants, and machine fuel are real per-job costs that scale with the work. Most operators build them in as a percentage of the subtotal, typically 4–8%. Heavy roof and organic-growth jobs sit at the top of that range because they burn more mix.
This is where your profit lives. After base price and consumables, a 25–40% markup is typical for pressure washing. New operators sometimes skip this entirely and only charge for their time, then wonder why there's nothing left after fuel, insurance, and equipment repairs.
Steep roofs, second and third stories, tight rooftop access, and no nearby water source all add time and risk. A flat $50–$150 access fee keeps you whole on the jobs that eat your afternoon.
Let's run the math on three different jobs. Assumptions: $0.18 per sq ft baseline flatwork rate, surface-method multipliers as above, 6% chemical & consumables fee, 30% markup, $200 minimum.
| Base price: 1,200 × $0.18 × 1.00 (flatwork) | $216.00 |
| Chemical & consumables: $216.00 × 6% | $12.96 |
| Gum removal add-on | $25.00 |
| Subtotal | $253.96 |
| Markup: × 1.30 | $330.15 |
| Quarterly route discount: −10% | −$33.02 |
| Final quote | $297 |
| Base price: 2,000 × $0.18 × 1.20 (soft wash) | $432.00 |
| Chemical & consumables: $432.00 × 6% | $25.92 |
| Heavy organic-growth condition fee | $40.00 |
| Subtotal | $497.92 |
| Markup: × 1.30 | $647.30 |
| Final quote | $647 |
No frequency discount on one-time jobs.
| Base price: 1,800 × $0.18 × 2.40 (roof) | $777.60 |
| Chemical & consumables: $777.60 × 6% | $46.66 |
| Gutter face whitening add-on | $90.00 |
| Steep-pitch / height access fee | $75.00 |
| Subtotal | $989.26 |
| Markup: × 1.30 | $1,286.04 |
| Final quote | $1,286 |
Recurring and contract work is gold. It smooths your revenue, cuts your setup cost per dollar earned, and turns a property into a route. Common discounts: 15% on a monthly commercial route, 10% on a quarterly storefront, 5–10% on an annual HOA or property-management agreement. Some operators go higher to lock in a route that fills a slow weekday.
Common a la carte items: gutter face whitening ($1–$2 per linear ft), rust or oxidation treatment ($40–$150), oil-stain treatment ($25–$75), gum removal ($1–$3 per piece or a flat fee), concrete sealing (quoted separately), and screen or window rinse ($5–$12 each). Charge for these explicitly. Never fold them silently into a base price.
A condition fee is your safety net for surprise jobs. A $35–$150 fee on top of the base price keeps you whole when a "light clean" turns out to be three years of lichen, a grease-soaked dumpster pad, or oxidation that needs a dedicated cleaner.
The PressureWashQuoteKit Excel workbook has all of this already built. Rate card, intake form, follow-up scripts.

It depends on the surface: roughly $0.12–$0.30 for concrete flatwork, $0.15–$0.35 for house soft washing, $0.30–$0.60 for roof soft washing, and $1–$3 for wood restoration. Per-square-foot pricing alone misses growth, access, and add-ons, so the rate-card method layers those on explicitly.
Yes. Soft washing leans on chemistry and dwell time rather than raw PSI, so it is the right method for siding, roofs, and painted surfaces, and it carries a higher per-square-foot rate than blasting flatwork with a surface cleaner. Price by the method the surface actually needs, not by the machine's maximum pressure.
Measure the footprint from the ground or from satellite imagery, estimate the roof area with a pitch factor, and add a steep-pitch or height access fee. Quote it as an estimate with the caveat that the final price may adjust after an on-site look. Never climb a roof you can't work safely just to win a quote.
For jobs over about $400, yes. An on-site look almost always wins the customer and protects you from a bad measurement. For smaller jobs, photos plus the intake form are enough. Free estimates eat your day; don't drive across town by default for a $200 driveway.
When you're consistently booked 1–2 weeks out, your margins are stable, and you've stopped attracting price-shoppers. New customers see the higher price; existing recurring and contract customers get grandfathered for 6–12 months, then bumped with notice.
This pricing model only works if you actually use it on every job. Build a calculator in your own spreadsheet, or skip that and use the PressureWashQuoteKit. It has the per-square-foot rate card, the customer intake form, and 13 ready-to-send follow-up scripts in one editable workbook.
