How to use this pressure washing estimate generator
Start from the three example lines and make them yours: set the area of each surface — house siding, driveway, deck, roof — and your per-square-foot rate, then add detergents, any rented equipment, and a trip or minimum-service charge. Change a quantity or price and the running total on the right updates instantly. Add a global markup and your sales-tax rate, then export a PDF to send. Nothing is uploaded — the draft saves in your browser so it's still here when you come back.
What to include in a pressure washing estimate
A quote that wins work — and protects you from a callback argument — spells out each surface instead of hiding it in one number. Include:
- Each surface as its own line, with the square footage or linear footage: house/siding wash, driveway, sidewalks, deck, patio, fence, roof.
- The cleaning method — soft wash (low pressure + detergent) for siding and roofs, higher pressure for flatwork. Say which; it sets expectations and protects delicate surfaces.
- Chemicals and treatments — soft-wash mix, degreaser, and any rust, oil, or stain spot treatment as a separate line.
- A minimum service charge so small jobs still cover your drive time, water, and chemicals.
- Assumptions and terms — access to water and power on site, and what heavy staining or organic growth could add to the price.
Typical 2026 pressure washing price ranges (edit to your market)
The tool seeds these as editable hints — they are current starting points, not gospel. Your real rates and local market beat any table:
| Service | Unit | Typical range |
|---|---|---|
| House & siding soft wash | sq ft | $0.15–$0.40 |
| Driveway & concrete flatwork | sq ft | $0.20–$0.55 |
| Deck & patio wash | sq ft | $0.30–$0.75 |
| Roof soft wash | sq ft | $0.20–$0.70 |
| Fence cleaning | linear ft | $1.50–$4.00 |
| Minimum service charge | job | $100–$250 |
A worked example
Say a job is an 1,800 sq ft house soft wash at $0.28, a 600 sq ft driveway at $0.32, and $45 of detergent and chemicals. With a 15% markup and 7% sales tax on the taxable chemicals, the tool lands on a $855.77 total. Change any input and the receipt on the right re-totals in integer-precise cents, so your numbers always add up. Working below your minimum service charge? Add the minimum-service line and the quote floors there instead.
Mistakes to avoid
- Quoting one round number. A lump sum invites haggling and callbacks; per-surface lines make your price make sense and protect your scope.
- No minimum charge. A $60 driveway across town loses money once you count drive time, water, and chemicals — set a floor.
- Not naming the method. Write "soft wash" for siding and roofs; it manages expectations and covers you if a customer expected a high-pressure blast on delicate surfaces.
- Forgetting access. State that the price assumes working water and power on site — a missing spigot or a locked gate changes the job.
