Not sure what you're looking at? The free stain identifier and safe pressure guide explain each stain and surface.
Why more pressure isn’t better

What happens on the day

Local stucco cleaning for Montclair, CA
In California, stucco and siding mostly collect dust, cobwebs and sprinkler spots, while shaded walls can grow mildew after winter rains. A soft wash handles both without etching stucco.
Near the coast, salt air leaves a film on siding, windows, screens and railings that dulls finishes and speeds up corrosion on metal. Regular rinsing and washing help protect them.
Much of California has hard water. Sprinklers and misters leave white mineral spots on walls, windows, fences and pool tile, and those spots need a mineral-safe cleaner, not more pressure.
Some cities in California limit outdoor water use, including washing hard surfaces with a hose, especially during drought declarations. Pressure washers use far less water than an open garden hose, but rules vary, so it's worth checking your city's current restrictions. Wash water should also be kept out of storm drains.

Stucco Cleaning: frequently asked questions
How much does stucco cleaning cost in Montclair, CA?
Stucco Cleaning typically costs $300-$800 for a typical stucco home, and usually takes 2-4 hours. The exact price depends on the size and condition, and you get it before any work starts. Call (555) 010-0000 for a free quote.
Do you use high pressure for stucco cleaning?
Stucco Cleaning is done with soft wash. Low pressure and the right solution remove growth and dirt without damaging the surface, and the growth takes longer to come back.
Is stucco cleaning safe for my plants and pets?
We pre-wet plants and lawns, keep cleaning solutions diluted to what the surface needs, and rinse landscaping again when we finish. Keep pets and children inside until surfaces are rinsed and dry.
How often should I schedule stucco cleaning?
Every 1-2 years. Shade, nearby trees, humidity and heavy traffic mean more frequent cleaning; sunny, dry spots can go longer. Our free cleaning frequency tool gives a recommendation for your climate.
What if it rains on the day?
Light rain doesn't stop most washing, but heavy rain, high wind, lightning and freezing temperatures do. If the weather isn't right, we reschedule at no charge. Our work is backed by a satisfaction guarantee.
