How much does patio cleaning cost?

It depends on size, material and how established any lichen or algae is, but most standard residential patios typically come in between £80 and £450. We'll always confirm a fixed price after seeing the patio rather than quoting blind over the phone.

How long does a patio clean take?

A standard residential patio usually takes half a day to a full day, including biocide treatment, dwell time and the clean itself. Larger areas, heavier growth or mixed materials can take longer - we'll give you a realistic timeframe when we quote.

Can you clean a patio that's got moss growing between the joints?

Yes - joints are often where growth establishes first, especially on block paving and older concrete flags, and we treat and clean the gaps as a specific step rather than just the flag faces. Left untreated, joint moss tends to spread outward across the whole surface.

Do you offer decking and fencing cleaning too?

We do, as add-ons alongside patio work - decking gets algae and grime buildup in a similar way to stone, and fencing can green up in shaded, damp spots. It's often more efficient to have it all done in the same visit.

Will the black spot lichen come back after treatment?

It can return over time since spores are airborne and shade or damp conditions won't change, but a proper biocide treatment kills the existing growth at the root, which means it takes considerably longer to re-establish than after a pressure-only wash. Sealing afterwards slows it down further.

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

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.

Older concrete flags and reclaimed stone often have softer, more porous surfaces than modern porcelain, so what's safe pressure for one can etch or pit the other. We match the method to the material every time.

Tree-Lined and Shaded Gardens

Gardens in Denton Burn with mature trees or dense boundary hedging keep patios shaded for much of the day, which slows drying after rain and creates the damp, low-light conditions black spot lichen and moss thrive in. Falling leaves and sap can also stain the surface between cleans.

These patios often need the joints cleared as much as the flags themselves, since moss and algae take hold in the gaps first and spread outward from there.

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.

Pressure Washing vs Our Treat-First Approach

A standard pressure wash blasts dirt and growth off the top of the stone using force alone. It's fast, and it looks dramatic, but on lichen-affected sandstone or limestone it can drive spores into the pores of the stone and damage soft pointing at the same time.

Our approach treats the biological growth chemically first, so it's actually dead before any pressure touches the surface. We then use the lowest pressure that gets the job done - often steam or a soft wash - which is gentler on the stone and the joints, and the clean lasts considerably longer as a result.

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.
