Rising damp in Wollondilly

Wollondilly is semi-rural country south-west of Sydney, with older brick, weatherboard and cottage homes on acreage and clay soils. Springs, creeks and high local water tables keep the ground damp, many older homes have no effective damp-proof course, and subfloors on large rural blocks stay moist. Rising damp and damp subfloors are common.

On rural ground the water table and drainage are often the drivers. We diagnose the source, install a damp-proof course where needed, manage drainage and ventilation, and finish in a breathable render so the repair lasts.

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 Wollondilly

Wollondilly's rural and semi-rural homes sit on clay and shale across the outer south-west, often on acreage with their own drainage. Older homesteads without a damp-proof course draw moisture up from damp ground, leaving salts that blister paint and blow plaster, while damp subfloors keep lower walls and air musty.

Rising damp FAQ — Wollondilly

Why is rising damp common in Wollondilly homes?

Wollondilly is semi-rural, with older brick and weatherboard homes on acreage and clay soils. Springs, creeks and high water tables keep the ground damp and many homes lack an effective damp-proof course, so rising damp is common in Picton, Tahmoor and Bargo.

Which Wollondilly suburbs do you cover?

All of them — including Picton, Tahmoor, Bargo, Thirlmere, The Oaks, Wilton, Douglas Park, Buxton, Yanderra, Pheasants Nest. If your suburb is not listed, call us; we cover the whole area.

We are on acreage with a high water table — what helps?

On rural Wollondilly blocks the water table and surface drainage are usually key. We look at where water sits and runs, treat the walls with a damp-proof course where needed, and improve drainage and subfloor airflow so the ground around the house stays drier.
