Pressure washing alone can blast the surface clean for a few weeks, but it leaves the spores in the pores of the stone ready to come back within a season. We treat first, then clean, so the lichen actually goes rather than just getting knocked back.

Why does a patio in Shilbottle go black in patches even when the rest of it looks fine? Nine times out of ten it's black spot lichen, not dirt, and it favours the shaded, damp corners of a garden - under trees, behind fences, on the north-facing side of the house.

It's not just about how it looks on the day either. Treating lichen properly rather than just pressure washing it means the result actually lasts, and a sensible sealing conversation afterwards protects the finish through the next few wet seasons.

Homeowners

Family Gardens and Everyday Use

If your patio is where the kids play, the barbecue goes and Sunday mornings happen, black spot lichen and slippery algae aren't just an eyesore - they're a genuine trip hazard underfoot. We treat and clean with that in mind, getting the surface properly grippy again, not just visually cleaner.

We work around furniture, planters and washing lines rather than asking you to clear the whole garden, and we're happy to talk through sealing at the end of the visit if you want the result to last into next year.

Limestone

  • Limestone is calcium-based, so it can react badly to strongly acidic cleaning products - we're careful about what we use on it. It's also porous like sandstone, so black spot lichen treatment and adequate dwell time matter here too.
  • We keep pressure low on limestone and let the biocide do the work of lifting growth, rather than relying on force that can etch or dull the surface.

What Actually Moves the Price

Sealing, re-sanding of block paving joints and re-pointing advice are usually priced separately from the base clean, since they depend on the condition we find once the surface is clean and dry.

Small patio (up to 15m²)
typically £80-£150
Sandstone or limestone, moderate growth
around £5-£7 per m²
Straightforward access, light growth
typically at the lower end of our range
