Caring for fiber cement siding

Fiber cement siding is durable and holds paint well, but its factory finish can be marked by high pressure, and manufacturers' care guides generally recommend low-pressure cleaning. Check your siding's care instructions if it is still under warranty.

Avoid: High pressure and close-range spraying, which can damage the finish and void the finish warranty.

How often: Every 1-2 years.

  • Green or black film on the shaded sides of the house
  • Dirt splash along the bottom of the walls
  • Cobwebs and wasp nests under the eaves
  • Chalky or dull-looking siding

Where the grime comes from

  • Pollen, dust and road grime
  • Spiders and insects under the soffits

Safe steps for homeowners

  • Clear plants and furniture away from walls before a wash
  • Look for loose siding, open seams or damaged caulk before anyone washes the house
