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.

Is it time for soft washing for fiber cement siding?

  • Green, black or gray film on siding, especially on the north side
  • Black streaks running down the roof
  • Moss or lichen on shingles or tile
  • A musty smell around shaded walls
  • Pressure washing would damage the surface

What causes the dirt and stains

  • Algae, mold and mildew that grow in shade and humidity
  • Roof algae that feeds on the limestone filler in shingles
  • Pollen and dust that give growth something to hold on to
  • Sprinklers and gutters that keep walls damp

Safe steps for homeowners

  • Trim back branches and shrubs that touch the house so walls can dry
  • Keep gutters clear so water doesn't overflow down the siding
  • Spot-clean small areas with a soft brush and mild detergent
  • Aim sprinklers away from the house

Common mistakes to avoid

  • Using too strong a mix, which can burn plants and fade surfaces
  • Using too weak a mix, which leaves growth alive and it returns quickly
  • Climbing ladders with a spray wand and chemicals
  • Mistaking soft washing for 'pressure washing on low'
