Start Clean: Pressure Washing Business
This course does not give legal, tax, insurance, or environmental advice. Pressure washing rules vary by city, county, and state. Before paid work, confirm local runoff, licensing, tax, and insurance requirements from official sources. Never pressure wash asphalt shingles or delicate siding, never let wash water reach storm drains unless your local authority allows a specific method, and do not take roof or height work you cannot do safely.
Welcome. Let's get to work.
This is a free, 12-unit, workbook-first course for launching a legal, safe, and profitable residential or small commercial pressure washing business in the United States. It includes plain-English lessons, official-source compliance checks, downloadable unit notes, practice tasks, quizzes, and a 30/60/90 launch plan. Your progress saves automatically in this browser.
How to complete this course
- Work sequentially: Do the units in order — each unit builds on the last. Plan to spend about 10 hours per week (averaging one unit per week).
- Watch actively:If units contain videos, pause at every new term, write down a one-line definition in your own words, then resume. Tick “Mark watched” when done.
- Practice and test:Read “The big picture” and “Critical points,” complete safe practice tasks, then take the quiz — answering out loud before revealing.
- Organize your notes: Download the unit notes (a markdown summary file) and keep them in a digital or physical binder.
- Validate achievement: When you meet the “Done when” standard, hit Mark unit complete in the unit checklist. Safety quizzes require 100% — no exceptions.
The 8 Hard Stops (memorize before Unit 4)
- Local rules win. Confirm stormwater, license, tax, and water-use rules for every city or county where you work.
- Never high-pressure an asphalt shingle roof or delicate siding. Use soft wash methods only where appropriate.
- Keep wash water out of storm drains unless a local official gives a specific allowed method in writing.
- Do not do paid work uninsured. General liability is the baseline before the first paid job.
- Treat the wand as a serious injury risk. High-pressure injection wounds need emergency medical care immediately.
- Never mix sodium hypochlorite with acids, ammonia, or unknown cleaners.
- Protect plants before, during, and after chemical work: pre-wet, cover sensitive plants, and rinse.
- Decline jobs with unsafe roofs, failing surfaces, lead-paint risk, uncontrolled runoff, or customers pushing you to ignore safety.
About the videos and sources
This course is workbook-first and does not require embedded videos. Legal, tax, environmental, and safety claims point students to official sources first: EPA, SBA, IRS, OSHA, state revenue agencies, city stormwater programs, and ARMA. Pricing and startup ranges are treated as planning ranges, not promises. Local rules always win, so students must complete the compliance research checklist for their own city, county, and state before paid work.
