Walkway and Paver Cleaning: Restoring Slippery, Mould-Covered Paths

Walkways, courtyards and paved entertaining areas often sit in shade for large parts of the day, which makes them one of the fastest surfaces on a property to develop mould, algae and general grime.

Why it's more than a cosmetic issue

A green or black film on pavers isn't just unattractive — it can become genuinely slippery when wet, especially on smooth-finished pavers or tiled outdoor areas. That's a real trip hazard for family, guests or customers walking through.

What a professional clean involves

  • Removing built-up mould, algae and organic staining from the paver surface.
  • Cleaning between joints and grout lines, not just the paver tops.
  • Adjusting pressure and technique for softer or older pavers to avoid damage.
  • Leaving the area safe and presentable for immediate use.

If your walkway, courtyard or entrance is looking tired or feels slippery underfoot, it's worth getting a free quote — it's often a quicker and more affordable fix than people expect.

How often should walkways be cleaned?

Shaded, high-traffic walkways often need attention every 6 to 12 months, while sunnier, well-drained paths can go longer. Courtyards enclosed by fences or dense planting tend to hold moisture longest and are usually the first area to show mould again after a clean.

Different paver types need different care

  • Concrete pavers can generally handle higher pressure than natural stone or older, worn pavers.
  • Sandstone and limestone are softer and need lower pressure to avoid surface erosion.
  • Joints and grout lines often hold more grime than the paver surface itself and need specific attention.
  • Sealed pavers respond differently to cleaning than unsealed ones, so it pays to know which you have.
