How PWNA Certification Actually Works

Getting certified isn't a quiz you click through in ten minutes. Each PWNA course walks contractors through the real methodology behind the discipline — the chemistry, the equipment settings, the surface-specific judgment calls — before testing that knowledge. You finish knowing why a technique works, not just that it works, which is the difference between a contractor who can talk through a callback and one who can't.


Most contractors complete a single certificate course in a few hours of focused study, and many hold two or three certifications covering the service lines they actually run. There's no required order — pick the certification that matches the work you're doing today, and add more as your service list grows.

Staying Aligned With Evolving Industry Standards

A PWNA certificate isn't a marketing sticker. It's tied to a national standard that's been refined by contractors and educators for over three decades, which is why property managers, commercial accounts, and even some insurance carriers treat it as a credible signal — not just a nice-to-have on a website.

Getting Certified With PWNA — Frequently Asked Questions

Frequently Asked Questions

In an industry where anyone with a pressure washer can call themselves a pro, PWNA certification is what tells customers you're the real deal — not just another listing to scroll past.

  • What certifications does PWNA offer?

    PWNA offers six core certificate courses: House Wash, Roof Cleaning, Flatwork, Fleet Washing, Wood Restoration, and Water Fed. Each one is a standalone credential built around a specific service line, so you can get certified in exactly the work your business actually does instead of one generic "pressure washing" badge.

  • How do I get PWNA certified?

    Choose the certification that matches your service offering, enroll through the Certificate Courses page, and complete the coursework at your own pace. Courses are built by working contractors and safety professionals, so the material reflects real jobsite conditions rather than generic classroom theory.

  • How much does PWNA certification cost?

    Cost depends on your membership tier. Contractor members pay a per-course fee for each certification, while Enterprise members get unlimited access to every certificate course — House Wash, Roof Cleaning, Flatwork, Fleet Washing, Wood Restoration, and Water Fed — included in their membership at no additional charge per class.

  • Which PWNA certification should I start with?

    Most contractors start with House Wash Certification since residential exterior cleaning is the highest-volume service in the industry, then add certifications that match how their business grows — Flatwork for concrete work, Roof Cleaning for soft-wash roof jobs, or Water Fed if you're moving into window cleaning. Choose based on what you're already selling, then build outward from there.

  • What does the House Wash Certification cover?

    The House Wash Certification covers soft washing systems, correct pressure settings for different siding materials, chemical dilution ratios, surface pre-treatment, and protection protocols for windows, landscaping, and architectural details — everything needed to clean a home safely without damaging the property.

  • Is PWNA certification recognized in the industry?

    PWNA has set training and safety standards in the exterior cleaning industry for over 30 years, and its certifications are built on documented, field-tested methods rather than trends. Certified contractors also gain eligibility for PWNA's contractor directory, which customers use specifically to find vetted, trained professionals.

  • Do I need to be a PWNA member to take a certification course?

    Yes — certificate courses are a membership benefit. Contractor members can access courses at a per-class rate, while Enterprise members get every certificate course included with unlimited access.

  • What's the difference between certificate courses and technical training?

    Certificate courses (House Wash, Roof Cleaning, Flatwork, Fleet Washing, Wood Restoration, Water Fed) result in a standalone credential tied to a specific service line. Technical Training modules — like Power Washing 101/102 or Coefficient of Friction — cover foundational skills and specialized techniques that support those certifications but aren't credentialed courses on their own.

  • Does PWNA certification help me win more jobs?

    Certification gives homeowners and commercial clients a concrete reason to trust you over an uninsured, unverified competitor — it signals that you've been trained on correct chemical ratios, surface-specific techniques, and safety protocols instead of learning by trial and error on someone's property. Certified contractors also become eligible for PWNA's public contractor directory, putting them in front of customers actively searching for vetted pros.

  • Can my whole crew get certified?

    Yes. Under a Contractor membership, each technician can enroll in courses individually at the per-class rate. Under Enterprise Membership, your entire team gets unlimited access to every certificate course with no per-class fees, making it easy to get every technician credentialed as they're hired.
