Caring for composite decking

Composite decking doesn't need staining, but it does grow mold and mildew, especially in shade and between boards. Most manufacturers recommend gentle cleaning, and some limit the pressure that can be used without affecting the warranty.

Avoid: High pressure and narrow tips, which can scar the surface and may void the warranty.

How often: Every year, more often in shade.

Serving Stuart, FL and nearby towns

Mildew and algae are the main reason Florida 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 Florida 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 Florida 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.

Much of Florida has hard water. Sprinklers and misters leave white mineral spots on walls, windows, fences and pool tile, and those spots need a mineral-safe cleaner, not more pressure.
