What to know about cleaning flagstone

Flagstone covers several stones, including sandstone, slate, bluestone and limestone, and they react differently to pressure and chemicals. Softer sandstone flakes if blasted, and mortar joints need care.

Avoid: High pressure on soft or layered stone, and acids on limestone.

How often: Every 1-2 years.

When to book pressure washing for flagstone

  • Driveway or walkways look dark, gray or streaky
  • Green or black growth in shaded areas and along edges
  • Slippery surfaces after rain
  • Oil, rust or tire marks you can't scrub out
  • You're getting ready to sell, seal or paint

What causes the dirt and stains

  • Dirt and pollen that settle into the pores of concrete
  • Mold, mildew and algae in damp, shaded spots
  • Oil and fluid drips from vehicles
  • Rust from sprinklers, furniture and fertilizer
  • Tire marks and general foot traffic

What you can do yourself

  • Sweep off leaves and loose debris so they don't stain
  • Blot fresh oil drips with cat litter or an absorbent right away
  • Point sprinklers away from walls and walkways to cut down on rust and hard-water stains
  • Rinse pollen off with a garden hose during heavy pollen season

Common mistakes to avoid

  • Etched lines and 'zebra stripes' from holding a narrow tip too close
  • Water forced into window frames, door sills and siding laps
  • Damaged plants and lawns from chemical runoff
  • Injuries: a zero-degree tip can cut skin, and wet surfaces are slippery

Is pressure washing for flagstone safe for my plants and pets?

We pre-wet plants and lawns, keep cleaning solutions diluted to what the surface needs, and rinse landscaping again when we finish. Keep pets and children inside until surfaces are rinsed and dry.
