Hunters Hill
RISING DAMP
EXPERTS

Hunters Hill holds some of Sydney's earliest housing — sandstone cottages and Victorian homes built by stonemasons in the 1800s, on a peninsula between the Lane Cove and Parramatta rivers. Solid stone walls with no damp-proof course, a high surrounding water table and river salts make rising damp and salt damp very common and often advanced.

Heritage stone needs careful, breathable treatment. We diagnose the source, install a damp-proof course suited to thick stone or rubble walls where needed, and finish with a lime or salt-resistant render so the historic masonry can keep breathing rather than being sealed in.

Hunters Hill's historic sandstone and brick homes — some of Sydney's oldest — sit on a peninsula with lime mortar and little or no damp-proof course. Moisture rises through the masonry carrying salt that blisters paint and blows plaster, and on this harbour peninsula salt damp works steadily into the heritage stonework.

Musty smell or a damp subfloor → Subfloor ventilation

Hunters Hill's heritage homes on peninsula land often have damp subfloors. We fit an underfloor ventilation system to keep the space dry.

Tide marks, peeling paint or salt on walls → Rising damp treatment

On old sandstone and brick, our DPC injection halts rising moisture without disturbing heritage fabric more than needed.

Blown, crumbling or hollow plaster → Damp plastering

We re-coat with a salt-resistant plaster system suited to older masonry.

Mould on walls, ceilings or in cupboards → Mould remediation

Our mould remediation removes growth and fixes the moisture source.

Penetrating damp or wet areas → Waterproofing

We apply tanking and waterproofing to below-ground and water-exposed walls.
