“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.

Roof cleaning for Mosman's terracotta, concrete tile and Colorbond. A soft wash treatment lifts the moss and lichen, then keeps breaking it down long after we leave.

Roof cleaning in Mosman is mostly a shade problem. The Federation brick and rendered harbourside homes here sit under heavy tree cover, and any slope facing south stays damp for months. That is where moss beds into the terracotta and lichen takes hold of the concrete tile. The same green that creeps up the render behind the sandstone walls is up there on the roof, out of sight until you notice the gutters staining.
We soft wash it. No pressure gun on century-old terracotta, no scouring the coating off Colorbond. The treatment does the slow work, killing the growth at the root and carrying on for weeks after we pack up, so the tile comes back to the colour it was fired in rather than a stripped version of it. Every roof is photographed against the checklist before we drive off, and it is the same operator each visit.
If your ridge line has gone dark over a street like Bradleys Head Rd, put your address into the instant quote. Firm bookable price in about 60 seconds, and it holds unless the roof is materially different to what you told us.
Every roof gets checked against the same list before we call it done. Surface by surface, ridge to gutter line. This is the finish that passes.
Moss and clumped growth treated and softened, then lifted off the tile or sheet. No gouging. No scraping the surface bare.
The right treatment worked across the whole roof so the black streaks and lichen die back for good. They do not wash off the top and grow again.
Colorbond and metal soft washed at low pressure. The factory coating stays on the roof where it belongs. No blasting.
Old terracotta and concrete tiles cleaned without the pressure that cracks them. What went up sound comes down sound.
Growth and debris flushed out of the valleys and off the gutter line. Water runs where it should, not back under the tiles.
Downpipes, garden beds and paths watched and rinsed. The mess off the roof does not end up staining what is under it.
Clean roof left to dry out properly. A dry roof stays clean longer than a roof that never sees the sun.
Job-close photos shot ridge to gutter against the checklist. Broken tiles, failed pointing or rust flagged and referred to a roofing partner. We do not re-roof or repoint.

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.

“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, most weeks. We work the streets around Raglan St, Musgrave St and Bradleys Head Rd, five minutes from Balmoral. Terracotta, concrete tile and Colorbond are all standard work.
Put your address into the instant online quote and a firm, bookable price comes back in about 60 seconds. Nobody comes out to look first, and the price holds unless the roof turns out materially different to what you told us.
Harbourside canopy keeps the south-facing slopes shaded and damp, and moss and lichen settle there first, exactly like the render behind your sandstone walls. Our soft wash keeps killing spores after we leave, so one visit holds far longer than a quick blast would, and most roofs here want a look once a year.
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.

Salt and lichen lifted, the stone left to breathe. Heritage stone, done properly.

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.
