Low pressure. Deep clean.

    Soft washing for surfaces that can't take the pressure.

    Roof shingles, painted siding, stucco, and delicate wood — high pressure destroys them. Soft washing uses biodegradable detergents at low PSI to kill mold and mildew at the root, not just rinse the surface.

    What's included

    • Asphalt shingle and metal roof cleaning
    • Painted siding (wood, fiber-cement, hardboard)
    • Stucco and EIFS exteriors
    • Vinyl siding (delicate areas)
    • Pool enclosures and screen cages
    • Algae, mildew, and black streak treatment

    Best for

    • Roofs with black streaks (gloeocapsa magma algae)
    • North-facing siding with visible mildew
    • Delicate painted surfaces that can't handle pressure
    • Homes older than 15 years
    • Properties under mature tree coverage
    • HOA notices for exterior discoloration
    The Process

    How it works

    Straightforward. No hidden fees, no bait-and-switch.

    01

    Inspection + Test

    I inspect the surface, test detergent compatibility in a hidden spot, and confirm the right dwell time for your materials.

    02

    Apply + Dwell

    Biodegradable cleaning solution is applied at low pressure and allowed to work. The detergents kill the organic growth — pressure doesn't.

    03

    Gentle Rinse

    Low-pressure rinse removes the dead organic matter and residue. Surface stays intact, landscaping stays safe.

    Soft washing is easy to do wrong. Wrong chemicals strip paint, kill landscaping, or leave streaks. I use the industry-standard chemical mix diluted properly, and I rinse adjacent plants first so nothing gets burned. It's the quiet skill of this trade — and where most crews cut corners.
