Brown rot and our solutions

Brown rot comes about when the mycelium develops extensively on the surface of infected timbers and masonry. Most brown rots will need very humid conditions to produce a mass of cotton wool like growth, and often water droplets are produced on the surface. Our team can identify brown rot, and provide full brown rot treatments and removals.


This kind of rot is also known as dry rot.

Most common kinds of brown rot, and how we identify them:


•Rot, Serpula Lacrymans (Cuboidal cracking to timbers, lilac and yellow colour, brown spores)

•Cellar Fungus, Coniophora Puteana (Cuboidal cracking to timbers, mainly in damp masonry)

•Mine Fungus, Antrodia (Firoporia) Vaillantii (Cuboidal cracking to timbers, pure white strands)

White rot identification and treatment

White rot, a form of wet rot, usually decays the timber through water saturation as a result of water ingress, leaking gutters, leaking plumbing or particularly porous brickwork. We offer a full wet rot treatment and removal service in Walsall and surrounding areas.


Most common forms of wet rot, and what we look for:


•Donkioporia expansa, (Mainly in hardwoods, woody fruiting body, associated with Deathwatch beetle)

•Phellinus contiguus (Affects hardwoods and softwoods with a stringy fibrously appearance)

•Asterostroma spp (Mainly in softwoods, courses a stringy fibrously appears over damp timbers)

•Pleurotus ostreatus (Very rarely found, mainly attacks panel products of hardwood)
