Pressure washing estimate generator — price it right, quote it in minutes

WashQuote prices a job the way experienced contractors do it on paper: each surface is measured in square feet, multiplied by the rate for that service type, and adjusted for how dirty it actually is. A lightly soiled maintenance clean bills at the base rate; medium soil — the typical residential job — adds 15%; heavy algae or years of neglect adds 35%. Every line on the quote shows its surface, rate and soil level, so the customer can see the price is measured rather than invented.

Three protections are built into the totals. First, your minimum job charge: if the measured lines come to less than your minimum (most contractors set $100–$250 to cover travel, setup and chemicals), the difference is added as a clearly labeled adjustment instead of silently inflating your rates. Second, the sanity checks compare every rate you enter against the typical US range for that surface and flag outliers in orange — they catch typos like $2.50 instead of $0.25 before the customer does. Third, the totals lay out discount, sales tax, deposit and balance on completion, so everyone knows what is paid and when.

The calculator runs entirely in your browser. Nothing you type — not your prices, not your customers' names or addresses — is sent to a server, and the page keeps working even when job-site signal drops to one bar. When you export, your browser's own print engine produces the PDF: no account, no watermark on your prices, no subscription. If you want a copy in your inbox, an optional email field appears at export time; declining takes one click and changes nothing.

Ranges verified September 18, 2026 against published US cost data (Angi; Housecall Pro’s 2026 pricing guide). Each cost page cites its own source.

Defaults are mid-range and fully editable — your market, your costs and your speed set the final number. New to per-square-foot pricing? Read the rate guide and the step-by-step pricing method, or grab the structure from our estimate template page.

Homeowners collect two or three prices for exterior cleaning. The contractor who leaves a clean, itemized PDF — business name on top, surfaces and rates in a table, total in bold, validity date at the bottom — reads as insured, established and trustworthy. The one who texts "350 for everything" reads as negotiable. Contractors consistently report closing more work at higher prices once they switch from verbal numbers to written estimates, and the document protects both sides when the job is done: no dispute about what was included, no mystery about the balance due. WashQuote exists to make that document a two-minute task you can finish from the customer's driveway.
