If you've ever watched a pressure washer strip paint off a deck or carve grooves into soft wood, you already know that more pressure isn't always better. Most homes in Louisville need soft washing, not blasting — and knowing the difference can save you thousands in repair costs.
What is pressure washing?
Pressure washing relies on high-PSI water to physically blast dirt, mildew and grime off hard surfaces. It works great on concrete driveways, sidewalks, brick patios and other dense materials that can take the force without damage.
What is soft washing?
Soft washing uses low pressure (about the same as a garden hose) combined with professional cleaning solutions that break down mold, algae, mildew and bacteria at the source. The detergent does the work — not the pressure — so it's safe for siding, painted surfaces, stucco, screens, and roofs.
When to use which
- Soft wash: Vinyl siding, brick homes, stucco, wood siding, soffits, gutters, roofs, screens and pool cages.
- Pressure wash: Concrete driveways, sidewalks, garage floors, brick patios and retaining walls.
Why this matters in Louisville
Kentucky's humid summers and shaded yards create the perfect conditions for algae and mildew. A soft wash treatment kills those organisms at the root — so the siding stays cleaner, longer, instead of just being temporarily rinsed.
