Dry rot arises from a fungal infestation that feeds on the cellulose within the timber, gradually breaking it down and causing the wood to become brittle and crumbly. The fungus releases spores that can travel through air or moisture, enabling it to spread rapidly across a property. What makes dry rot particularly dangerous is its ability to affect not only visible timber but also concealed areas, such as floorboards, joists, and wall cavities. If left untreated, the damage caused by dry rot can necessitate significant and costly repairs, including the replacement of timber, plaster, and other building materials.
Identifying dry rot early is critical to mitigating its impact. The signs can often be subtle, especially when the fungus develops in hidden areas. A persistent damp or musty odour is often one of the first indicators of dry rot. This odour lingers even when the timber appears dry, suggesting that the decay may already be underway.
As the infestation progresses, affected timber becomes brittle, cracked, and often crumbles upon touch. Another distinguishing feature of dry rot is the presence of fungal growth, which may appear as a cotton wool-like substance that is white or grey in colour, with rust-red or purple tinges around its edges. Additionally, the timber itself may shrink, darken, and develop cracks, further undermining its structural integrity. Mycelium, a thread-like growth produced by the fungus, can spread across surfaces, providing a visible clue to the extent of the infestation.
