Frequently Asked Question
What is rising damp and how does it damage my property?
Rising damp is moisture from the ground that travels upward through walls, causing structural damage, salt deposits, and mould growth if not treated.
Rising damp occurs when moisture from the ground travels upward through the walls and foundations of a building, bypassing or degrading the damp-proof course (DPC). This happens because the mortar and brick are porous materials that absorb water through capillary action, similar to how a sponge soaks up liquid. Over time, the moisture carries salts from the soil, which crystallise on the wall surface and cause significant structural damage.
The damage from rising damp can be extensive if left untreated. It weakens the structural integrity of walls, causes plaster to crack and peel, promotes timber rot in floorboards and skirting boards, and creates an environment where mould and mildew thrive. In Port Melbourne properties, where older homes are common, rising damp is a frequent issue that can compromise both the safety and value of your home. If you notice damp patches appearing on lower walls, efflorescence (white salt staining), or a musty odour, it's important to have the property assessed promptly.
