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.

I'm not sure what my patio is made of - does that matter?

It matters quite a bit, since sandstone, limestone, porcelain, concrete and block paving all respond differently to pressure and chemicals. We identify the material as part of the initial assessment, so you don't need to know beforehand - just get in touch and we'll work it out on site.

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.

What if you find a problem with the patio once you start cleaning?

We'll stop and talk to you before continuing. Things like loose flags, failing pointing or unstable edging sometimes only become obvious once dirt and growth are removed, and we'd rather flag it honestly and discuss options than plough on regardless.

Patio cleaning prices in Hurworth on Tees typically run from around £4-£8 per square metre depending on material, condition and how much black spot lichen treatment is needed, with most standard-sized patios coming in as a fixed quote rather than an hourly rate.

Proper treatment means killing the lichen and algae first with a biocide, letting it work, then cleaning the dead growth away. It takes longer than a straight pressure wash but it's the only approach that actually lasts.

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.

Victorian Terrace Courtyards and Original Flags

Victorian terraces in Hurworth on Tees often still have the original stone flags or early concrete slabs in small rear courtyards, laid long before modern pointing methods. Decades of damp, shade from boundary walls and limited airflow make these some of the worst spots for black spot lichen we see.

The pointing between old flags is frequently lime-based or has been patched over the years, so we're careful with pressure and always flag any joints that look loose or crumbling before we start rather than after.

New Homeowners Inheriting an Old Patio

Moving into a property with a patio you didn't lay yourself often means inheriting someone else's neglect - years of black spot lichen, unknown pointing condition, or a material you're not sure how to look after. We'll tell you honestly what it's made of and what it needs.

That includes flagging anything beyond cleaning, like joints that need re-pointing, before we start, so you're not surprised by an issue a wash uncovers rather than causes.

Proof of the Work, Not Just Our Word

Biocide trained (2024): Up-to-date training means black spot lichen and algae get treated at the root, not just blasted off the surface.
Softwash, steam and low-pressure methods: We match the method to the material rather than using one setting for every patio.
Asbestos awareness trained: Trained to recognise and work safely around legacy materials on older properties.
Biocide trained (2024): Properly trained in the treatments needed to actually shift black spot lichen for good.

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.

Porcelain or concrete, light growth	from around £4-£5 per m²
Sealing (per m², after cleaning)	typically £6-£12 per m²
Block paving joint re-sanding	typically £3-£6 per m²
Decking clean add-on	from around £4-£7 per m²
