Soft and Safe House Washing for Homes and Properties

PWNA Certified House Washing for Homes Across Delaware & Chester County

PWNA certification matters because the exterior cleaning industry has a wide range of “levels.” Some contractors rely on raw pressure and hope. PWNA Certified House Washing emphasizes proper technique, safety, and proven methods that protect the materials on your home while delivering strong, consistent results.


Simple Clean LLC is a PWNA Certified contractor and owner-operated local business. That means your project is handled with professional standards, clear communication, and accountability from start to finish.


This service is ideal for:

  • Vinyl siding
  • Hardie board / fiber cement
  • Stucco and EIFS (surface-appropriate methods)
  • Painted siding and trim
  • Soffits, fascia, gutters (exterior faces), and shutters
  • Front entry areas, porches, and exterior accents


What “House Washing” Actually Means (and Why It Works)

A professional house wash is not the same thing as pressure washing siding. The safest approach is typically soft washing—a low-pressure rinse paired with the power of soaps and chemistry to break down organic growth at the root.


This process is designed to:

  • Remove algae, mold, mildew, and pollen
  • Lift traffic film and atmospheric grime
  • Brighten siding and trim for a fresh, clean finish
  • Reduce recurring buildup by treating the cause—not just the symptoms


You’ll see the difference quickly. And the clean lasts longer when the biology is handled correctly.

The Simple Clean House Washing Process

Every property is different, so the method must match the material. Our approach combines professional detergents with controlled application and careful rinsing to keep your home protected.


Our PWNA-aligned house washing process typically includes:

  • Surface evaluation (siding type, oxidation, heavy growth zones, sensitive areas)
  • Pre-wet landscaping and protection of targeted areas
  • Application of professional-grade soaps and cleaning agents (as needed)
  • Proper dwell time to break down growth and staining
  • Low-pressure rinse for a consistent, clean finish
  • Final walkthrough and detail check around entry points and trim


This is how a house wash stays safe—and looks “new” again.

Frequently Asked Questions About Pressure Washing

  • Is house washing safe for siding?

    Yes—when done correctly. PWNA Certified House Washing emphasizes surface-appropriate methods and low-pressure rinsing to protect siding, trim, and exterior finishes.

    Most homes benefit from routine washing every 12–24 months, depending on shade, moisture, surrounding trees, and visible organic growth.
