Independent quoting software for pressure-washing contractors.

Who runs this

WashQuoter is built and edited by a small independent team based in the United Kingdom, with day-to-day product decisions made by the founder. We are not a trade association, not a training school, and not a licensed contractor. Editorial work is done by the WashQuoter Editorial Team and reviewed against primary sources before publication.

We do not employ chemists, industrial hygienists, insurance brokers, or attorneys. When a subject requires that expertise, we cite the source and point you to the licensed professional who can advise on your specific situation.

Why this site exists

Most pressure-washing contractors quote jobs from mental math, a text message, or a paper carbon-copy pad. That produces inconsistent pricing and quotes that look thin next to a competitor's proposal. WashQuoter closes that gap with a fast calculator plus a branded PDF the customer can sign.

On the research side, most public writing about pressure-washing pricing and safety is either thin blog content or vendor marketing. We publish the primary-source version: what OSHA actually requires, what SDS sheets actually say, what BLS wage data actually shows.

How we make money

WashQuoter is a software product. The free tier includes five quotes per month with WashQuoter branding on the quote footer. The Pro tier at $9 per month removes our branding, adds unlimited quotes, PDF download, and a customer database. Annual billing is $90 per year. Full pricing sits on the home page.

We do not take affiliate commissions from chemical suppliers, equipment brands, or insurance providers. We do not sell reader data. Guides that name a specific manufacturer do so because that manufacturer publishes real specifications we can cite, not because we have a commercial relationship.

Editorial standards

Every guide on this site follows the same rules:

1. Every numeric claim traces to a primary source. Federal agencies (OSHA, EPA, IRS, SBA, BLS), state contractor licensing boards, manufacturer specification sheets, published SDS documents, or recognised trade associations. If we cannot cite it, we cut it.
2. No endorsement claims. WashQuoter is not affiliated with or endorsed by PWNA, UAMCC, IWCA, OSHA, EPA, or any regulator or trade body. When we describe an association's published guidance, we quote it and link to the source.
3. Not legal, insurance, or engineering advice. We describe what regulations and industry standards say. We do not tell you what to do about a specific job, injury, claim, or licensing question. For those, we point you to your state licensing board, a licensed insurance broker, an attorney, or the SDS for the product you are actually using.
4. Every long-form page shows a Last reviewed date. Guides in this batch are marked 30 June 2026. When we refresh a page, we bump the date.
5. Sources block on every guide. Every long-form page carries a Sources section at the bottom. Aggregated on /sources.
6. Errors: email us. Send the page URL and the primary source that contradicts our claim to [email protected]. We investigate every report and fix substantive errors within a business day.
7. Plain prose. No em dashes. No AI-tell phrases. If a sentence would not fit in a magazine, we rewrite it.

What we cover

• Pressure-washing pricing benchmarks by service type and region
• Insurance categories relevant to pressure-washing contractors (general liability, workers compensation, inland marine, commercial auto)
• State-by-state licensing requirements for pressure-washing work
• Chemistry and PPE guidance for sodium hypochlorite (SH) based cleaning
• Equipment specifications (PSI, GPM, hot vs cold water, direct drive vs belt drive)
• Marketing and lead-generation channels that solo operators actually use
• Product topics on the quote engine itself

What we don't cover

• Medical advice on chemical exposure. If you or an employee has been exposed to sodium hypochlorite, call Poison Control (1-800-222-1222 in the United States) and follow the SDS for that specific product.
• Specific legal advice on contracts, subcontracting, or employment. Talk to an attorney licensed in your state.
• Roofing structural or engineering advice. Roof cleaning intersects with fall protection and shingle warranty terms that a licensed roofer or engineer should sign off on.
• Tax preparation for your business. Talk to a CPA or Enrolled Agent. We link to IRS publications where relevant.
• Non-United-States pricing benchmarks. All wage and cost data below is US unless noted.

How the quote engine works

The short version: contractors enter surface square footage or service type, the calculator applies a per-square-foot rate, service-type multiplier, trip charge, and regional adjustment, then produces a printable quote branded to the contractor's business. Full formula and source list on the methodology page.
