How we clean it

Soft washCleaning method

Signs you need exterior mold & mildew removal

  • Black, green or gray spots and film

Not sure what you're looking at? The free stain identifier and safe pressure guide explain each stain and surface.

What can go wrong with DIY pressure washing

  • 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.

Serving Durango, CO and nearby towns

In Colorado, strong sun fades siding and paint, and winter grime builds up along the bottom of walls. A gentle spring wash removes it without stripping a finish that the sun has already weakened.

Much of Colorado 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 Colorado 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.

How much does exterior mold & mildew removal cost in Durango, CO?

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.
