Can you clean Indian sandstone without damaging it?

Yes - sandstone is porous and can be relatively soft, so we treat black spot lichen and algae with a biocide first, then clean with steam or low-pressure washing rather than high pressure, which protects both the surface texture and the pointing between flags.

How often should a patio actually be cleaned?

It varies with material, shade and local conditions, but a treated and sealed patio can often go two to three years between cleans, while an untreated, shaded patio in a damp spot might need attention every year. We can suggest a realistic interval once we've seen yours.

Is there anything I need to do before you arrive?

Not much - clearing loose garden furniture, planters or toys from the patio surface helps us get started straight away, but otherwise we bring everything we need. Reasonable parking access near the property is helpful if space is tight.

Do you work on patios in Haughton regularly, or is it a special trip?

Haughton falls within our normal 45-mile working area from our Washington base, so it's part of our regular schedule rather than an occasional job - which generally means more flexible availability for booking.

Haughton Patio Cleaning: Sandstone, Limestone & Block Paving

Patio looking patchy or slippery in Haughton? Proper biocide treatment plus expert cleaning gets black spot lichen gone for good, not just for a fortnight.

Whether it's a small courtyard patio behind a terrace, a large sandstone patio on a newer estate, or a block-paved driveway-turned-patio, the cleaning approach in Haughton starts with the same question - what's it actually made of, and how bad is the black spot lichen.

For patios around Haughton that means sandstone and limestone get treated gently enough to protect the pointing, while block paving and concrete flags that can handle more get a proper deep clean including the joints, not just the flag faces.

Steps for a Heavily Overgrown Patio

1
Clear loose debris
Moss, leaves and loose organic matter are cleared by hand first so treatment can reach the stone directly.
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
Extended dwell time
Heavier growth needs longer for the biocide to work through fully - we don't rush this stage.
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
Joint and edge detail work
Gaps between flags or block paving are cleaned individually where growth has been established for years.
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.

Doing It Safely - for the Patio and the Garden

Biocide treatments and cleaning chemicals need careful handling around plants, ponds and lawns, and we're trained in spill management so run-off is controlled rather than left to find its own way into a border or drain. We protect nearby planting before we start.

On the stone itself, safety means not overdoing the pressure - too much force on old pointing or soft sandstone can loosen joints or pit the surface, creating problems that weren't there before. We check the condition of the patio first and clean to what it can actually handle.

Tree-Lined and Shaded Gardens

Gardens in Haughton 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.

Typical Patio Cleaning Costs

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.

Sealing (per m², after cleaning)	typically £6-£12 per m²
Restricted access or heavy growth	typically £20-£80 more
Combined patio + block paving driveway	often quoted as one job, ask for a combined price
