Stone & Exterior Cleaning in Castlecrag, NSW 2068

Castlecrag (2068) is unlike anywhere else in Sydney — Walter Burley Griffin’s planned bushland suburb, where heritage stone houses sit inside the landscape rather than on top of it, and the streets follow the contours of the Middle Harbour escarpment. With Middle Cove and Castle Cove (2069) sharing the same bush-and-bay character, this pocket demands the gentlest methods we have.

Griffin stone is irreplaceable

The Knitlock and sandstone construction of the heritage houses — and the stone walls, steps and outcrops threaded through every garden — can never meet high pressure. Our stone cleaning is chemistry-led: identify the stone, treat the biological blackening the bushland shade feeds, lift it at a pressure the stone carries, and seal breathably. On listed fabric we’ll tell you plainly what should and shouldn’t be touched.

Living inside the bush

Full canopy means gutters that fill relentlessly — twice-yearly clears that double as ember-season prep on the reserve interface — plus flat and low-pitch roofs collecting leaf mats, and shaded paths that our moss removal keeps safe on the suburb’s steep walkways.

Glass to the water

The contemporary homes stepping down to Sugarloaf and Sailors Bays run on view glass — cleaned with purified water from the ground, no ladders on these gradients — with facades soft washed. Serving Castlecrag, Middle Cove and Castle Cove under Willoughby City Council. Request a quote today.
