Founding Streets open in Wahroonga 2076
Wahroonga's heritage sandstone gets soft washed, so a century of lichen and salt lifts off the block without scarring the face. That is sandstone cleaning done the way old stone deserves.

Wahroonga runs to grand homes on generous blocks, and a lot of them sit on original sandstone: front steps, garden walls, the piers by the gate. Our sandstone cleaning here is a soft wash, not a hire-shop pressure gun. High pressure on hundred-year-old block chews the surface and leaves it porous, so we lift the lichen and salt with low pressure and the right dwell time instead.
Under the oaks along streets like Burns Rd, that stone goes green fast. Shade holds moisture, moisture feeds lichen, and the steps get slick before you notice. Sandstone near the estate gardens tends to carry salt bloom on top of the green, so we treat both rather than just blasting the surface layer and moving on.
Every step and wall gets photographed against the checklist when we finish, so you can see the before and after on your own stone. Put your address into the instant quote and you will have a firm price back in about a minute.
Every block gets read before it gets touched. Here is the finish it is done to, surface by surface.
Soft washed at low pressure. Black lichen and salt lifted, the natural honey colour back, no blast scarring.
Treated at the root and drawn out over days, not scrubbed off the top. It does not grow straight back.
The white efflorescence eased off the face and the stone left open to breathe, never sealed shut over damp.
Worked gently around, old lime pointing left intact. Loose or failing joints flagged in the condition report, not force washed.
Trafficked sandstone cleaned back to grip and colour, edges and nosings done by hand where the machine cannot reach.
Copings, balusters and any carved faces cleaned by hand at close range so the crisp lines stay crisp.
A breathable seal only, applied once the stone is fully dry. It sheds salt and water and still lets the block breathe.
Job-close photos against the checklist. Anything past maintenance is named, marked, and referred to a specialist partner.

Booking a one-off? A couple of cleans a year adds up. The Schmick Plan folds the whole exterior into one monthly price and keeps it handled, so you never think about it again.

“Couldn’t fault them”
Had the windows and the driveway done. Turned up right on 8, finished before lunch, and the driveway honestly looks brand new. Same guy came back for the gutters last month and remembered our dog’s name. Couldn’t fault them.
“Should’ve done it years ago”
They sent me photos of what came out of our gutters. Revolting. Glad it’s gone. Lovely guys too.
“Came out after the storm”
We’re on their monthly plan. After that big blow in June they were out two days later and sorted everything without us having to chase. Worth it for that alone.
“Honest, which is rare”
Our sandstone wall had gone black and I’d assumed it was ruined. It’s come up beautifully. There was one damp patch he said needed a stone specialist rather than pretending he could fix it, which I appreciated. On time, tidy, very fair on price.
“Neighbours all asked who did it”
Windows are unreal. Two of the neighbours came over to ask who did them before the van had even left the street. Booking was easy and they text you when they’re on the way.
“10/10”
Got the whole outside done before we hosted Christmas. Mum asked if we’d had the place repainted. Showed up when they said, price was exactly what they quoted.
Yes. We soft wash heritage sandstone across Wahroonga, from the estate gardens end to the homes along Burns Rd. Steps, garden walls and gate piers are all exterior work we cover.
Put your address into the instant quote and you get a firm, bookable price in about 60 seconds. It holds unless the stone is materially different from what you described, so there is no waiting on an inspection.
The big oaks and tile roofs keep the stone shaded and damp, which is exactly what lichen wants. A soft wash clears it without opening up the surface, and most shaded steps stay clean for a good while before they need another visit.
One crew, one visit. Book a single job or hand us the whole exterior.
Inside and out, tracks and screens. The squeegee line you can see from the street.
Render, brick and weatherboard brought back without blasting a thing. Ten years of grey, gone by lunch.
Cleared, flushed and photographed. The before you never wanted to see, and the after you will.
Pressure cleaned back to the day they were poured. Sealing available.
A film of grime is a tax on every panel. We take it off, quarterly, and your yield thanks you.
Moss, lichen and mould lifted off tiles and Colorbond. Soft washed, never blasted.
Timber, Colorbond and rendered fences washed back. The street side done first.
Tell us the address and what the street sees. The same person who would do the job gets back to you, not a call-centre.
