Sandstone cleaning in Mosman starts with the walls nobody notices until they turn black. This is a suburb of Federation brick and white render, but underneath the harbourside homes it's sandstone doing the heavy lifting: retaining walls terracing down to the water, steps, piers, the block that keeps the gardens from sliding into the street.
That stone is a century old and soft as it looks. South-facing faces under the tree cover grow lichen in black rosettes that eat into the surface, and anything within sight of the water carries the salt haze that hangs over the harbour most of the year. A hire-shop pressure gun takes both off and a layer of the stone with them, leaving pockmarks that never grow back. We soft wash instead. The lichen and the salt lift, the sandstone keeps its face, and the whole wall is photographed against the checklist before we leave.

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.
Meet Jake. He runs Schmick jobs in Mosman, and the same person comes back each visit — no rotating crew, no call-centre between you and the work.
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 work the harbourside streets around Raglan St and Bradleys Head Rd regularly, five minutes up from Balmoral. Retaining walls, steps and piers are all part of the job.
Put your address into the instant quote and a firm, bookable price comes back in about 60 seconds. Nobody needs to come out and look first, and the price holds unless the wall is materially different to what you described.
That's lichen, and it favours the south-facing faces the tree cover keeps damp and shaded. Down near the water, salt haze off the harbour feeds it further. We soft wash it off rather than blast it, and most walls hold clean for a couple of years before they need another pass.
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.
