Hiring a power washing company might seem like a straightforward task—search online, read a few reviews, and book a service. But not all power washing companies are created equal. If you want your property treated with care, the job done safely, and long-term results that last, it’s crucial to choose a contractor who holds the right certifications and credentials.
Let’s break down why certifications matter, what to look for, and how to avoid getting stuck with an amateur who might do more harm than good. 💡
💼 Why Certifications Matter in Power Washing
Power washing equipment can be powerful—often releasing water at thousands of PSI (pounds per square inch). Without proper training, that pressure can damage siding, strip paint, crack concrete, or harm delicate surfaces.
That’s where certifications come in. Companies that invest in professional training and certification demonstrate:
- A commitment to industry standards
- Up-to-date knowledge of equipment and techniques
- A focus on safe, eco-friendly practices
- Professionalism and liability awareness
Would you trust an uncertified electrician to rewire your house? The same mindset should apply to exterior cleaning services.
🏆 Top Certifications to Look For
When hiring a power washing company, ask if they hold any of the following certifications:
✅ PWNA – Power Washers of North America
One of the most respected organizations in the industry. PWNA-certified contractors follow strict guidelines on chemical usage, safety, and environmental protection.
✅ UAMCC – United Association of Mobile Contract Cleaners
Offers business and technical training for pressure washers. UAMCC also promotes environmentally responsible practices.
✅ SoftWash Systems Certified
Specialized certification for companies offering “soft washing,” a gentler cleaning method ideal for roofs and delicate surfaces.
✅ OSHA Safety Certifications
While not exclusive to power washing, OSHA training shows a commitment to on-the-job safety and risk reduction.
✅ EPA Compliance
While not a formal “certification,” a good power washing company should know how to manage wastewater in compliance with EPA Clean Water Act regulations. 🌍
🔍 How to Verify Certification Claims
Don’t just take a contractor’s word for it—ask for proof. Here’s how to do it professionally:
- 📄 Ask to see a copy of their certification documents or training credentials
- 🔗 Visit the certifying organization’s website to search for the company by name
- 🗨️ Look for logos or badges on their website, truck, or uniforms
- 📞 Call the certifying body if you’re unsure whether the certification is valid
Legitimate companies will be happy to share this info. If they hesitate or make excuses, that’s a red flag 🚩.
🧠 Experience Still Matters
While certification is important, it’s not the only factor. Ask how long they’ve been in business and whether they specialize in the type of cleaning you need:
- Residential vs. Commercial
- Roof and gutter cleaning
- Graffiti removal or stain restoration
- Post-construction cleanup
A certified newbie might not have the hands-on experience of a seasoned pro—so weigh both equally.
🌿 Certifications and Eco-Friendliness
If you care about your landscaping, local waterways, or just minimizing your environmental impact, certification can also indicate a company’s green practices.
Professionally trained washers are more likely to:
- Use biodegradable detergents 🌱
- Apply chemicals sparingly and safely
- Reclaim and filter wastewater properly
- Avoid runoff that can damage soil or plant life
Ask if the company uses eco-friendly methods or offers water recovery systems—especially for large-scale jobs.
🛡️ Certified Contractors = Peace of Mind
There’s more at stake than clean concrete. A certified contractor is far more likely to be:
- Properly insured (liability and worker’s comp)
- Transparent in pricing
- Well-versed in local regulations
- Backed by guarantees or warranties
In short, they’re less likely to leave you with damaged siding, dead grass, or legal headaches.
📋 Questions to Ask Before You Hire
Here’s a simple checklist you can use during your first conversation:
✅ What certifications do you hold?
✅ Can you show proof of training or industry association membership?
✅ Are you insured and licensed in this area?
✅ What experience do you have with [specific type of cleaning]?
✅ Do you follow EPA guidelines for wastewater and runoff?
🧽 Final Thoughts
Anyone can rent a power washer and call themselves a “pro.” But hiring a certified, trained, and experienced power washing contractor can mean the difference between a clean home and a costly repair.
So do your homework. 📚 Ask questions. Verify their credentials. And don’t be afraid to choose quality over price—because when it comes to power washing, you truly get what you pay for.
