From the free quote to the final rinse, exterior mold & mildew removal for brick in your area follows a simple process: inspect, protect, clean, rinse and check. With brick, the right approach is low-pressure wash.

Method and pressure

Low-pressure washCleaning method
Usually 500-1,500 PSI with a wide fan tip, held well back from the mortarPressure

Cleaning solution: Soft wash for algae and mildew; a masonry-specific cleaner for efflorescence and mortar haze.

Cleaning brick safely

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.

Signs you need exterior mold & mildew removal for brick

  • Black, green or gray spots and film
  • Slippery walkways and decks
  • Musty smell near shaded walls
  • Growth that returns soon after rinsing

What causes the dirt and stains

  • Shade, humidity and poor air flow
  • Organic debris and pollen
  • Surfaces that stay damp after rain or sprinklers

What you can do yourself

  • Improve sun and air flow by trimming plants
  • Keep gutters and sprinklers from soaking walls
  • Clean small areas with an outdoor mildew cleaner, following the label

Why more pressure isn’t better

  • Blasting growth off without killing it, so it grows back fast
  • Mixing cleaning chemicals, which can release toxic gas
  • Damaging plants with runoff

What happens on the day

  1. Identify surfaces and growth
  2. Protect plants and fixtures
  3. Apply a solution that kills the growth
  4. Rinse at low pressure
  5. Post-treat where helpful to slow regrowth

This service is for outdoor surfaces. Mold inside the home, in attics or in wall cavities needs a mold remediation specialist, not a pressure washing company.

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.
