A few quick details, a real price back fast.
The reason people miss
It's not just how it looks. It's what you're standing on.
A mossy driveway or a stained patio usually gets booked for how it looks, and that's a fair reason on its own. But the film building up underneath the staining is the more urgent one: moss and algae hold moisture at the surface, and a wet path or step coated in it turns genuinely slippery, in a way a dry-looking patio rarely gives away until someone's already down.
That's the part a jet wash actually fixes, not just papers over. Lifting the growth off the surface removes the layer causing the slip risk, not just the colour it leaves behind, which is why this is often as much a safety visit as a cosmetic one, especially anywhere near a step, a ramp, or a route to the front door.

See it happen
Drag the handle. This is a real job, not a render.
Same patio, same day. What comes off with the moss isn't just the stain, it's the layer that made every slab underneath it slippery when wet.
No filters, no angle tricks: one visit, one camera position, before the hose came out and after it went away again.
Every surface is different
One setting doesn't fit every surface.
Pick a surface to see how the approach actually changes, not just the name of what's being cleaned.
Pressure & technique
Block paving, tarmac and concrete stand up to a firmer pressure than most exterior surfaces, but joints between blocks still need care so sand doesn't wash out from between them.
Regrowth treatment
Often worth it here. Driveway joints are exactly where weed and moss regrowth comes back fastest, since they trap moisture at ground level.
Drying & finish
Full sun exposure usually dries a driveway quicker than a shaded patio, but we'll always confirm on the day rather than promise a fixed time.
Sun exposure matters too
Two identical driveways, two different stories.
The same surface behaves differently depending on how much daylight it actually gets.
Sun-exposed
- Open driveways and south-facing patios with a clear run of daylight
- Dries fastest of the two, often within a few hours in good weather
- Regrowth is slower here, so a treatment matters less urgently
Shaded
- Patios under trees, north-facing walls, decking that never quite dries out
- Holds moisture longest, which is exactly why moss and algae come back fastest here
- Worth asking about a regrowth treatment sooner rather than later
Booking by season
When it's worth booking, and when we'll say wait.
Winter
A hard frost pauses a booking rather than going ahead. Water refreezing on a jet-washed surface makes it more slippery, not less, so we'll always reschedule around it rather than risk that.
Spring & autumn
Peak regrowth season for moss and algae. This is when a regrowth treatment earns its keep most, and when bookings tend to be busiest.
Summer
The fastest drying window of the year, but rain on the day doesn't rule a booking out. We'll always confirm on the day rather than cancel on a forecast alone.
Whatever's growing on it, the same cover and re-clean guarantee applies to every exterior visit.

Jet washing, answered
What people ask most before booking a driveway, patio or exterior clean.
Driveways, patios, decking and render are the most common. Each surface needs a different pressure and technique, which is exactly what we confirm before starting.
Not when it's done at the right pressure for the surface -- which is why we assess the material first rather than running one setting on everything.
Where a regrowth treatment is genuinely appropriate for the surface, we'll offer it -- mention your concern on the quote form and we'll confirm what applies.
Both -- algae and moss on a path or driveway aren't just unsightly, they're a real slip risk, which is often the bigger reason to book this.
It depends on the surface and the weather on the day -- we'll give you a realistic estimate before we finish up.
