Method and pressure

Soft washCleaning method

Signs you need exterior mold & mildew removal

  • Black, green or gray spots and film
  • Slippery walkways and decks

Why it gets dirty

  • Shade, humidity and poor air flow
  • Organic debris and pollen

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 Roanoke, AL

Mildew and algae are the main reason Alabama homeowners wash their siding. Shaded walls can turn green within months, and pressure alone doesn't kill the growth, so we use a soft wash solution that does.

Parts of Alabama are exposed to hurricanes and tropical storms. After a storm, washing removes mud, debris and salt spray from siding, screens and walkways. Check for damage first: loose siding, broken screens and roof damage need repair before anyone washes them.

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.

Spring pollen season in Alabama coats houses, cars, screens and patios in a yellow-green film, and pollen gives mildew something to feed on. Many homeowners book their wash after pollen season ends so the house stays clean longer.

Red clay soil is common in parts of Alabama. Rain splashes it onto the bottom of the siding, walls and walkways, and its iron-rich color can stain light surfaces. It usually needs a dedicated clay or rust cleaner rather than pressure alone.

Exterior Mold & Mildew Removal: frequently asked questions

How much does exterior mold & mildew removal cost in Roanoke, AL?

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.
