House Washing & Soft Washing Jacksonville, FL

If you’ve noticed dark streaking, greenish film, or black spots creeping across your siding, that’s not dirt in the traditional sense — it’s biological growth, usually algae or mold, feeding on the humidity that sits on your home’s exterior for most of the year here in Jacksonville. Pressure alone can knock the visible layer off, but if you don’t kill the organism at the root, it grows right back within weeks, often looking worse than before because the surface is now roughened and easier for spores to grip. That’s the entire reason soft washing exists as a distinct method: low water pressure carries a cleaning solution formulated to kill algae, mold, and mildew at the cellular level, so what comes back is a much slower, much lighter regrowth cycle instead of an immediate rebound.

Signs You Need House Washing

• Dark streaking running down from the roofline or gutters onto siding
• Greenish or black film, especially on north-facing walls or shaded areas
• A chalky, dull appearance that used to be a brighter, cleaner color
• Visible growth around window sills, corners, and other areas where moisture collects
• It’s been over a year since the exterior was last cleaned

Our Process

1. Inspect and Protect

We walk the exterior first, identify the siding material (vinyl, stucco, brick, or painted wood), and cover or tape off landscaping, outlets, light fixtures, and anything else nearby that needs protecting before we start.

2. Apply the Soft Wash Solution

A cleaning solution formulated for exterior siding is applied at low pressure, giving it time to break down algae, mold, and mildew at the surface and root level rather than just physically knocking it loose.

3. Low-Pressure Rinse

Once the solution has had time to work, we rinse the surface at a pressure level appropriate for your specific siding material — low enough to protect vinyl, stucco, or original paint, but thorough enough to fully clear the dissolved growth.

4. Final Walkthrough

We walk the property with you (or send photos if you’re not on-site) to confirm the results before we consider the job done.

Why This Matters in Jacksonville’s Climate

Jacksonville’s humidity sits between 70 and 90 percent for most of the year, which is exactly the environment algae, mold, and mildew need to establish and spread on an exterior wall. Homes under heavy tree canopy — common in neighborhoods like Riverside, Avondale, and Ortega — see this even faster, since shade keeps the siding damp longer after every rain. That’s why a soft wash isn’t just a cosmetic fix; treating the organism at the root is the only approach that actually slows down how fast the growth returns, rather than restarting the clock at zero every time.

What’s Included

• Full exterior wash of vinyl, stucco, brick, or painted wood siding
• Soft-wash cleaning solution that kills mold, algae, and mildew at the root
• Landscaping covered and rinsed before and after
• Outlets, light fixtures, and vents taped off for protection
• Spot treatment for stubborn buildup around trim, corners, and window sills

What Affects Your Price

• Square footage and number of stories of your home
• Siding material — vinyl, stucco, and brick each require slightly different technique and time
• Severity of buildup, since heavier growth takes longer to fully break down
• Accessibility, including gated yards or landscaping that limits equipment placement
