Wet Rot and Woodworm

Wet Rot requires a high moisture content within timber, usually in excess of 60% and is likely to occur over a lengthy period of time. Whilst some of the visible symptoms of both Dry Rot and Wet Rot are similar, the treatments required are vastly different. Woodworm is a destructive beetle that attacks most timber with the Common Furniture Beetle and Wood Boring Weevil being the most commonly found, although only one of these require chemical treatment applications. Ensure you have a suitably qualified surveyor identify and explain the difference to you and avoid unnecessary works



The hyphal strands in Wet Rot are not as structurally destructive as Dry Rot and whilst it is always advisable to have a qualified surveyor inspect damage to property, you may not require fungicidal or biocidal treatments.


Wet Rot always requires a high level moisture source and some wet rots may result in bleaching of the wood; this is most common in exposed timbers whereby wood eventually loses its strength and in some situations may become dangerously unsafe. Always engage a suitably qualified surveyor to inspect timber decay and identify the difference between various problems. B.C.
