Exterior Mold & Mildew Removal in Wakefield, NH

In New Hampshire, snow and slush that sit against the house leave a band of grime and mildew along the lower siding, and shaded north walls stay damp long after the thaw. A spring soft wash removes winter grime before it bakes on over the summer.

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.

How much does exterior mold & mildew removal cost in Wakefield, NH?

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.
