Best Power Washing in Los Angeles, CA

How much does power washing cost?

A driveway cleaning runs $100—$250. House exterior washing averages $200—$500 for a standard home (soft wash). A full property package (house, driveway, patio, walkways) runs $300—$800. Deck cleaning is $100—$250. Pricing is typically per square foot or by surface type.

What is the difference between power washing and soft washing?

Power washing uses high-pressure water (2,000—4,000+ PSI) and is effective for concrete, brick, and stone. Soft washing uses low pressure (under 500 PSI) with a cleaning solution (bleach/surfactant) — the right method for vinyl siding, wood, and roofs to avoid surface damage.

How often should I power wash my house?

Most homes benefit from professional exterior cleaning every 1—2 years. Homes in humid climates, near trees, or with north-facing siding develop algae and mildew faster and may need annual cleaning. Regular cleaning protects paint and siding from deterioration.

Can power washing damage my siding?

Yes — high pressure on vinyl siding, wood, or stucco can force water behind the siding, crack caulk, strip paint, and cause permanent damage. Always use soft washing (low-pressure + cleaning solution) on house exteriors. Concrete, brick, and stone can handle high pressure.

Should I power wash before painting?

Yes — cleaning the surface before painting is essential for adhesion. Power or soft wash the exterior surface 1—2 weeks before painting to allow proper drying. Painting over dirty or mildewed siding causes premature peeling.
