From the free quote to the final rinse, pool deck cleaning for flagstone in your area follows a simple process: inspect, protect, clean, rinse and check. With flagstone, the right approach is low-to-moderate pressure wash.

How we clean it

Low-to-moderate pressure washCleaning method
Usually 1,000-2,000 PSI, depending on the stonePressure

Cleaning solution: A stone-appropriate cleaner, tested on a small area first.

Cleaning flagstone safely

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.

Common mistakes to avoid

  • Peeling or etching a coated 'cool deck' surface with high pressure
  • Chemicals and wash water getting into the pool
  • Pitting travertine with acid cleaners
  • Slips on wet, treated surfaces

What happens on the day

  1. Check the deck material and coating
  2. Protect the pool and nearby plants
  3. Pre-treat algae and stains with pool-safe methods
  4. Clean with pressure suited to the surface
  5. Rinse thoroughly away from the water

Many pool decks have a textured acrylic or 'cool deck' coating. These need lower pressure than bare concrete, and a deck that is peeling may need recoating rather than more cleaning.
