Soft Washing for Cedar Shake Roofs in Stone Mountain, GA
Mildew and algae are the main reason Georgia 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 Georgia 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 Georgia 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 Georgia. 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.
