The City of Sydney holds some of the oldest masonry in the country — narrow Victorian and Edwardian terraces, converted warehouses and below-grade basements, most built on sandstone with lime mortar and no damp-proof course. A century of salt, ground movement and city groundwater means rising damp and lateral damp through basement walls are everyday problems here.
These buildings need to breathe. The lasting fix is to diagnose the true source, install a new damp-proof course where the wall needs it, and finish with a breathable, salt-resistant render — never a sealing cement or acrylic that traps moisture behind the surface.
Inner-city terraces and converted warehouses sit on old footings with failed or absent damp-proof courses, and basements sit below the water table. Moisture rises through the masonry leaving salts that blister paint and blow plaster — and in below-ground rooms it can saturate walls and feed persistent mould if left untreated.
City terraces and ground-floor apartments often have damp, unventilated subfloors and basements. We install subfloor ventilation to dry them.
Inner-city Victorian terraces rarely have a sound damp course. Our damp-proof course injection stops the rise.
We re-coat with a breathable salt-resistant plaster system suited to old masonry.
Our mould remediation clears growth and fixes the damp behind it.
We waterproof and tank basements, cellars and below-ground walls common in the CBD.

The inner city is full of Victorian and Edwardian terraces and old warehouse buildings put up before damp-proof courses existed, many with basements below the water table. Sandstone footings, lime mortar and city groundwater make rising and lateral damp very common in Surry Hills, Darlinghurst and Redfern.
All of them — including Surry Hills, Darlinghurst, Pyrmont, Ultimo, Glebe, Redfern, Chippendale, Potts Point, Woolloomooloo, Haymarket, The Rocks, Waterloo. If your suburb is not listed, call us; we cover the whole area.
Yes. Basements and lower-ground levels often get lateral damp pushing through below-grade walls as well as rising damp. We diagnose which it is and treat accordingly, with tanking or waterproofing where a basement wall needs it.
