The secret to exterior mold & mildew removal for stucco is using the right method, not the most pressure. In Diamondhead, MS, we match the cleaner and pressure to the surface so it comes out clean without damage. For stucco, that means soft wash.
Method and pressure
Cleaning solution: A diluted house-wash solution with surfactant, given time to dwell, then a gentle rinse.
Cleaning stucco safely
Traditional stucco is porous and holds moisture, which is why it streaks green and black in humid and shaded spots. Hairline cracks are common, and high pressure can force water into them or break off the finish coat.
Avoid: High pressure, which can etch the texture, blow out patches and push water behind the wall.
How often: Every 1-2 years.

Local exterior mold & mildew removal for stucco for Diamondhead, MS
Mildew and algae are the main reason Mississippi 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 Mississippi 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 Mississippi 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.
