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?

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.
