From the free quote to the final rinse, pre-paint washing for stucco in Amherst, NY follows a simple process: inspect, protect, clean, rinse and check. With stucco, the right approach is soft wash.
Method and pressure

What to know about cleaning stucco
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.

Serving Amherst, NY and nearby towns
Humid summers in New York 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.
