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.

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 Langley Park 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.

Late winter and early spring is when patios in Langley Park look their worst - months of damp weather have given algae and black spot lichen a head start, and the low sun shows up every dark patch. It's also the point where most people start thinking about the garden again.

1960s and 70s Estate Patios

Patios from this era in Langley Park are often concrete flags or early paving slabs, laid directly onto sand or hardcore with minimal drainage falls built in. Over fifty-plus years the surface has usually absorbed a lot of green algae and moss into a slightly rougher, more porous finish than newer materials.

These older concrete flags can be more prone to surface crazing, so we test pressure carefully rather than assuming they'll take the same clean as modern slabs.

Getting a Patio Ready for Viewings or Sale

A clean, even-coloured patio makes a real difference to how a garden photographs and how it feels to walk round on a viewing. Black spot lichen and green staining read as neglect even when the rest of the house is well kept, and it's one of the cheaper things to put right before putting a property on the market.

We can usually turn a patio around in a day, and we'll work to a timeframe if you've got viewings or photos booked in.

Steps for a Heavily Overgrown Patio

  1. 1

    Clear loose debris

    Moss, leaves and loose organic matter are cleared by hand first so treatment can reach the stone directly.

  2. 2

    Strength-matched biocide application

    On badly affected patios we use a stronger treatment mix, adjusted to the material so sandstone and limestone aren't over-treated.

  3. 3

    Extended dwell time

    Heavier growth needs longer for the biocide to work through fully - we don't rush this stage.

  4. 4

    First pass clean

    An initial wash lifts the bulk of the dead growth, often revealing the true condition of the stone and joints underneath.

  5. 5

    Joint and edge detail work

    Gaps between flags or block paving are cleaned individually where growth has been established for years.

  6. 6

    Second rinse and inspection

    A final rinse and a full inspection confirms nothing's been missed and flags any re-pointing that's now worth doing.
