Cumberland's housing is a dense mix of Federation, postwar brick and fibro on the central-western plain, where clay soils hold water against the footings. Many homes were built decades ago with damp-proof courses that have since failed, and lower-lying pockets near the river stay damp. Rising damp and salt-affected walls are common.
We confirm whether the moisture is rising through the walls, sitting in the subfloor or driven by drainage, then treat the cause with DPC injection, ventilation or drainage and finish with a breathable, salt-resistant render.
Cumberland's older brick homes around Auburn, Merrylands and Granville sit on reactive clay near the river. The clay holds water against footings and moves with the seasons, breaking down damp-proof courses, so moisture rises through the walls leaving salts that blister paint, blow plaster and rot skirtings.
Cumberland's older brick homes on clay often have damp, poorly ventilated subfloors. We fit subfloor ventilation to dry them out.
Our DPC injection installs a new damp-proof course to stop moisture climbing the walls.
We strip and re-coat with a salt-resistant plaster system so walls finish clean.
Our mould removal clears mould and fixes the damp feeding it.
We apply tanking and waterproofing to below-ground and wet-area walls.

Cumberland mixes Federation, postwar brick and fibro homes on clay soils that hold water. Aged or failed damp-proof courses and low-lying riverside pockets make rising damp and salt-affected walls common in Auburn, Merrylands and Granville.
All of them — including Auburn, Merrylands, Granville, Guildford, Lidcombe, Wentworthville, Greystanes, South Granville, Berala, Regents Park. If your suburb is not listed, call us; we cover the whole area.
On Cumberland's clay soils, heavy rain leaves water sitting against the footings for longer, which the wall draws up. If the damp-proof course has failed, the rise gets worse after wet spells. We check drainage and the course together so it stays dry.
