From the free quote to the final rinse, exterior mold & mildew removal for brick in California follows a simple process: inspect, protect, clean, rinse and check. With brick, the right approach is low-pressure wash.
How we clean it
Cleaning solution: Soft wash for algae and mildew; a masonry-specific cleaner for efflorescence and mortar haze.
What to know about cleaning brick
Brick is tough, but the mortar joints are softer than the brick itself, and older soft-fired brick can pit. Organic growth comes off with a soft wash; mineral deposits such as efflorescence need a masonry-safe cleaner instead of more pressure.
Avoid: Zero-degree tips and close-range blasting that erode mortar joints, and strong acids on brick that hasn't been pre-wet.
How often: Every 2-3 years for most homes.

Exterior Mold & Mildew Removal for Brick in California
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.

Do you use high pressure for exterior mold & mildew removal for brick?
For brick: usually 500-1,500 PSI with a wide fan tip, held well back from the mortar. What we avoid: zero-degree tips and close-range blasting that erode mortar joints, and strong acids on brick that hasn't been pre-wet. The cleaning solution does most of the work, followed by a gentle rinse.
Is exterior mold & mildew removal for brick 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 exterior mold & mildew removal for brick?
Every 2-3 years for most homes. 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.
