Rising damp in Georges River

The Georges River area mixes Federation, Californian bungalow and postwar brick homes on a blend of sandstone and clay near the river. Older homes often have failed damp-proof courses, sloping blocks push moisture laterally, and lower-lying riverside pockets hold water. Rising and lateral damp are both common.

On these mixed sites we confirm whether moisture is rising, coming laterally through an uphill wall, or sitting in the subfloor, then treat with DPC injection, drainage or ventilation and a breathable, salt-resistant finish.

Signs you have rising damp
A tide mark up to ~1m on internal walls
Blistering, bubbling or peeling paint
White salt deposits (efflorescence)
Crumbling or hollow-sounding plaster
Damp patches near the floor / skirting
A persistent musty, damp smell

What rising damp does in Georges River

Georges River homes around Hurstville and Kogarah sit on a mix of clay and sandy soils with older brick and aged damp-proof courses. Ground moisture rises through the walls leaving destructive salts that blister paint and blow plaster, and on lower-lying blocks it keeps subfloors damp and feeds recurring mould.

Rising damp FAQ — Georges River

Why is rising damp common in Georges River homes?

The Georges River area mixes Federation, bungalow and brick homes on sandstone and clay near the river. Failed damp-proof courses, sloping blocks and low riverside pockets make rising and lateral damp common in Hurstville, Kogarah and Mortdale.

Which Georges River suburbs do you cover?

All of them — including Hurstville, Kogarah, Mortdale, Oatley, Penshurst, Beverly Hills, Carlton, Riverwood, Peakhurst, Blakehurst, Hurstville Grove. If your suburb is not listed, call us; we cover the whole area.

What is the difference between rising and lateral damp?

Rising damp climbs up from the ground through the base of the wall; lateral damp pushes in sideways, often through an uphill or below-ground wall on a sloping block. Both are common around the Georges River and need different treatment, which we confirm at inspection.
