Black spot lichen and green algae spread fast across Indian sandstone, limestone and concrete flags, and once it takes hold a garden hose won't shift it. The dark speckling that starts in the shady corner of a patio in Columbia creeps outward every wet spell, and by the time it reaches the seating area most of it is bonded into the stone rather than sitting on top.

Why does a patio in Columbia 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.

The figure that actually matters is cost per year of clean patio, not the invoice total - a treated and sealed patio can stay looking good for two or three seasons, while a quick pressure-only wash can green up again within months.

Handling a Patio with Mixed Materials

  1. 1

    Map the materials

    Many gardens combine sandstone, block paving and concrete edging - we identify each zone before starting so methods can differ across the same patio.

  2. 2

    Treat by zone

    Biocide strength and dwell time are adjusted per material rather than applied uniformly across the whole area.

  3. 3

    Clean by zone

    Porous stone gets gentler steam or low-pressure cleaning; denser porcelain or concrete can take a firmer wash where needed.

  4. 4

    Blend the finish

    We finish with an overall rinse so the different zones read as one consistent, even-coloured patio rather than a patchwork.

Cost Per Square Metre

For larger or irregular areas it's often easier to think per square metre rather than a flat fee. Porous stone needing biocide treatment generally sits toward the higher end, while denser materials in good condition sit lower.

Porcelain or concrete, light growth
from around £4-£5 per m²
Sandstone or limestone, moderate growth
around £5-£7 per m²
Heavy black spot lichen, any material
around £7-£9 per m²
