Sandstone, travertine, timber and pavers all fail differently under too much pressure. Each one gets the setting it can take, and the slick green film that makes them dangerous comes off either way.
The green film that grows on a shaded pool surround is not just unsightly. Wet, it has roughly the friction of soap, and it collects exactly where people are walking with wet feet and no shoes. It is the reason this work gets booked before Christmas far more often than it gets booked for looks.
The catch is that these are the softest surfaces on the property. Sandstone pits. Travertine loses its fill. Timber furs up and lifts its grain, and once the grain is raised no amount of later care puts it back. Pavers give up their jointing sand and start to move. Every one of them will be permanently damaged by the pressure a driveway wants.
So the pressure comes down and the chemistry does more of the work. The growth is treated and given time to die properly at the root, then lifted at a setting matched to what is underneath it. It takes longer. It is the only way these surfaces come up clean and stay intact.

A single alfresco area routinely has travertine underfoot, a timber deck off it, rendered piers holding the roof up and a run of pavers to the pool gate. They do not share a setting, and treating them as one surface is how one of them gets ruined.
Each material gets tested in an inconspicuous spot before the main area is committed to. It is a small habit that costs ten minutes and has saved a great many stone patios.
The slick, shaded areas where the algae grows fastest and matters most.
Soft stone, cleaned at a pressure that leaves the surface where it is.
Cleaned with the grain, and left ready for oiling or staining if that is the plan.
Including the moss in the joints, with re-sanding raised where it’s needed.
Tiled entertaining areas, splashbacks and the grout between them.
Soft-fall surfaces, play equipment and awning fabric where it can be safely washed.
We clean and prepare. Applying a finish is separate work, and the surface has to be properly dry first.
Loose boards, popped nails and rot are photographed and handed to you, not fixed.
A landscaper’s job. We’ll show you where the falls have gone.
The water, the pump and the filter belong to your pool contractor. We work on what surrounds them.
Where a deck is already grey through and lifting, cleaning reveals the condition rather than reversing it.
Tannin from leaf litter and rust from furniture feet can be decades old. They lift; they don’t always vanish.
Entertainment areas are full of things that do not enjoy being washed. Most of this is a five-minute conversation at quote stage.
Moved clear before we start. Coordinated with you rather than shifted without asking.
Kept clear of runoff and treatment. If a cover is needed over the water, that gets planned in.
Deck lights, external outlets and speakers identified and worked around.
Loose boards, proud nails and soft spots found and photographed before pressure goes anywhere near them.
On pavers, how much sand is left in the joints decides the setting — and whether re-sanding should follow.
Where the water leaves the area, so it isn’t pushed toward a door threshold or a garden bed.
More surfaces per square metre than any other job we do, so the walk-around carries more weight here.
Photos matter more here than anywhere — the materials are the quote.
Straightforward areas are measured remotely. Multi-surface entertaining areas usually earn a site visit.
Named surface by surface, so you can see exactly what is and isn’t included.
Each material tested somewhere out of sight before the main area is committed to.
Growth treated and given time, then lifted at the setting that surface takes. Surrounds rinsed.
And a note of anything we found underneath that you’ll want to deal with.

It can, at the wrong setting — soft stone pits and travertine loses its fill. That is why these surfaces are cleaned chemistry-first at low pressure, and why we test an out-of-sight patch before committing to the main area.
Yes, gently and with the grain. Timber is the least forgiving surface out there: too much pressure raises the grain permanently and leaves a furry, splintery finish. Done properly, a deck comes up clean and is ready for oil once it has dried out.
Regularly — pool surrounds are one of the most common jobs on this list, because that is where the slippery growth ends up. The water itself and the pool equipment stay with your pool contractor.
In this climate, eventually. Treating the growth at the root rather than blasting it off buys you considerably longer, and generally you’ll get a good six months of it looking like new before it starts to return.
That is separate work and needs the timber fully dry, so it is a second visit rather than the same afternoon. Raise it at quote stage and the timing gets planned properly.
