Dry rot refers to a type of wood decay caused by certain types of fungi, also known as True Dry Rot. These fungi digest parts of the wood which give the wood strength and stiffness.
We use a Sovereign Chemical treatment that kills rot by filling in the channels of the damaged wood, killing the rot and restoring structural integrity.
In certain buildings, particularly those with solid 9 inch (or greater) brickwork and those built using lime mortar and flintstone, dry rot can travel through and along the wall surface behind plaster and render. For this reason we recomend that where dry rot is found, plaster and wall coverings should be stripped back a metre past the infestation in all directions, and the whole area treated.
Dry rot only attacks wet timber, so plaster need not be removed where there is no timber or the timber is dry (ie outside the zone of wetting that caused the outbreak).
Identifying the source of water and allowing the affected timbers to dry will kill dry rot.
