The honest answer is that pressure washing on its own won't solve it long-term. Lichen has a root structure that grips into sandstone and limestone, so it needs a biocide treatment to kill it off before any cleaning happens, otherwise it's back within months.

We treat, clean and can seal patios across Oxclose - sandstone, limestone, porcelain, concrete flags and block paving all covered, with a biocide treatment for black spot lichen and moss before any washing starts.

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 growthfrom around £4-£5 per m²
Sandstone or limestone, moderate growtharound £5-£7 per m²
Heavy black spot lichen, any materialaround £7-£9 per m²

Exposed and High-Ground Properties

Properties on higher, more exposed ground around Oxclose catch more wind-driven rain, which keeps stone surfaces wetter for longer even without direct shade. That constant dampness is enough on its own to encourage green algae and black spot lichen without any tree cover involved.

Wind exposure also means more airborne debris and grit settling into joints and pores, so a clean here often needs a bit more attention to the pointing and gaps between flags, not just the flat surface.

Low-Maintenance Gardens for Retirement

For anyone who wants a garden that looks after itself, a treated and sealed patio needs far less scrubbing and sweeping than one left to green up on its own. We can talk through a sensible cleaning interval so it's a call every year or two rather than something to worry about.

We're happy to explain what we're doing and why as we go, and there's no pressure to add extras like sealing or re-pointing on the day - just honest advice on what would actually help.

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.

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.

Not Sure What Your Patio Needs?

A biocide treatment followed by the right clean for your material costs a bit more upfront than a straight pressure wash, but it lasts years longer. We'll explain exactly what your patio needs and why.
