The right method for the job

Soft washCleaning method

When to book exterior mold & mildew removal

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

Where the grime comes from

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

Easy upkeep between cleanings

  • 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

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

  • 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.

Exterior Mold & Mildew Removal in Dilworth, MN

In Minnesota, snow and slush that sit against the house leave a band of grime and mildew along the lower siding, and shaded north walls stay damp long after the thaw. A spring soft wash removes winter grime before it bakes on over the summer.

Much of Minnesota 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.

Do you use high pressure for exterior mold & mildew removal?

Exterior Mold & Mildew Removal 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 exterior mold & mildew removal 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?

Every 1-2 years in humid or shaded areas. 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.
