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.

Do you provide before-and-after photos of the work?

Yes, we can provide photo evidence of the patio before and after treatment and cleaning, which is particularly useful for landlords, letting agents, or anyone wanting a record for their own files.

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.

Can I get a quote without you visiting first?

For a rough idea, yes - a few photos and the approximate size over the phone or by message can get you a ballpark figure. For a firm, fixed price we'd normally want to see the patio in person, particularly if there's significant black spot lichen or the material's uncertain.

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.

Late winter and early spring is when patios in Seahouses 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.

The idea that a pressure washer alone will sort a lichen-covered patio is one of the most common misunderstandings we come across in Seahouses. Blasting black spot lichen off the surface just spreads live spores across the rest of the stone and into the joints - it looks clean for a few weeks, then comes back worse.

A Typical Patio Clean, Visit by Visit

1
Initial assessment
We check the material, extent of black spot lichen or algae, and the condition of the pointing and any edging before quoting.
2
Biocide treatment
Affected areas get treated with a biocide to kill lichen, moss and algae at the root, not just on the surface.
3
Dwell time
We leave the treatment to work - this is what actually kills the growth rather than just loosening it.
4
Clean and rinse
Steam or low-pressure washing removes the dead growth and ingrained dirt, with attention paid to the joints as well as the flags.
5
Final check and advice
We walk the patio with you, point out anything worth knowing - loose pointing, a weak flag, whether sealing would help - and leave it tidy.

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.

Former Colliery Terrace Housing

In the ex-colliery terraces around Seahouses, rear yards were often flagged rather than turfed, and many still have the original stone or early concrete underfoot. Coal dust staining from decades past can sit under more recent algae growth, so a clean sometimes reveals old ingrained marks that a wash alone won't lift.

Narrow yards and high boundary walls typical of this housing keep these areas shaded and slow to dry, which is exactly the environment black spot lichen prefers - it's a genuine repeat-treatment area rather than a once-and-done job.

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.

What Actually Moves the Price

Sealing, re-sanding of block paving joints and re-pointing advice are usually priced separately from the base clean, since they depend on the condition we find once the surface is clean and dry.

Porcelain or concrete, light growth	from around £4-£5 per m²
Sandstone or limestone, moderate growth	around £5-£7 per m²
Sealing (per m², after cleaning)	typically £6-£12 per m²
Restricted access or heavy growth	typically £20-£80 more
