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

  1. Identify surfaces and growth
  2. Protect plants and fixtures
  3. Apply a solution that kills the growth
  4. Rinse at low pressure

Exterior Mold & Mildew Removal: frequently asked questions

How much does exterior mold & mildew removal cost in Baker, MT?

Exterior Mold & Mildew Removal typically costs $250-$700 for typical exterior growth on a 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 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.
