Exterior Mold & Mildew Removal in Cave Spring, VA
Humid summers in Virginia grow green algae and black mildew on the shaded sides of homes, especially on vinyl and painted wood. A soft wash kills the growth rather than just knocking it off, so the siding stays clean longer.
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 Virginia 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 Virginia. 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.
