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.
Why does a patio in Stanley 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.
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 Stanley 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.
Side Passages, Steps and Tight Access
Not every patio is reachable in a straight line from the road - side passages, steps down to a sunken garden, or a shared access path all change how a job's approached. We ask about this at quoting stage so there are no surprises on the day.
Longer hose runs or hand-carrying equipment through a tight passage can add a little time, which we'll factor honestly into the price rather than springing it on you afterwards.

Honest advice
If sealing or re-pointing isn't needed, we'll tell you rather than upsell it.
How We Clean Your Patio, Step by Step
We start with a walk round to check the material, the level of black spot lichen or algae, and anything unusual like loose pointing or an uneven flag. Then we apply a biocide treatment to any lichen, moss or algae and leave it to work - this is the step that actually kills the growth rather than just knocking it back.
Once the treatment has done its job we clean with steam or low-pressure washing depending on the surface, working the joints as well as the flag faces. Block paving usually gets re-sanding advice if the jointing sand has washed out, and we finish with a rinse and a check over before we leave.
Concrete Flags
- Older concrete flags, especially from the 1960s-80s, tend to be more porous than modern cast slabs and can show surface crazing after decades outside. We check condition before deciding on pressure, since heavily worn concrete can be more fragile than it looks.
- Concrete takes biocide treatment well, and a proper clean can bring genuinely tired-looking flags back to a much more even, presentable finish.
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.
1960s and 70s Estate Patios
Patios from this era in Stanley 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.
