Hornsby sits on Sydney's bushland edge where rainfall is higher and blocks are often steep, shaded and backed by bush. Federation and brick homes on these sites have damp ground around the footings, poor subfloor airflow and aged damp-proof courses. Sandstone and clay soils hold water, so rising damp and damp subfloors are common.
Sloping, high-rainfall sites need the cause confirmed before treatment — it may be a failed course, water running toward the house, or a wet subfloor. We diagnose, then treat with DPC injection, drainage or ventilation and a breathable finish.
Hornsby's homes sit on the shaded, bush-backed upper North Shore where sandstone and clay hold moisture and subfloors stay damp. Ground moisture rises through aged brickwork leaving salts that blister paint and blow plaster, while poor subfloor airflow on bushland blocks keeps lower walls and air musty.
Hornsby's elevated, bush-fringed blocks often have cool, damp subfloors. An underfloor ventilation system keeps the space dry.
Our rising damp repair injects a new DPC to stop moisture rising through the walls.
We re-coat with breathable replastering that resists salt damage.
Our mould remediation clears mould and fixes the moisture cause.
We apply tanking and waterproofing to below-ground walls and wet areas.
A free on-site inspection pinpoints the cause and gives a fixed quote.
Hornsby is on the bushland fringe with higher rainfall and steep, shaded blocks. Federation and brick homes there have damp footings, poor subfloor airflow and aged damp-proof courses, so rising damp and musty subfloors are common in Asquith, Waitara and Pennant Hills.
All of them — including Hornsby, Hornsby Heights, Asquith, Waitara, Wahroonga, Normanhurst, Thornleigh, Pennant Hills, Mount Colah, Berowra. If your suburb is not listed, call us; we cover the whole area.
On a sloping Hornsby block, check whether stormwater and ground run toward the house and whether the subfloor stays damp. Both push moisture into the walls alongside any failed damp-proof course. We assess all three at inspection and treat what we find.
