It is important to have a prevention strategy for Wet & Dry Rot.

 

Once untreated timber becomes damp & is allowed to remain in that condition, it can be attacked by any of the multiple species of wood rotting fungi. The terms Wet Rot and Dry Rot are used to describe fungal attack to timbers in buildings.

There is only one true Dry Rot: Serpula Lacrymans.
Dry Rot is in itself a contradiction in terms; initially the fungus will only occur in moist conditions where both the wood & atmosphere are damp.

The name Dry Rot is due to the fact that this fungus can germinate at a lower moisture content than Wet Rot & that the decay caused by the Dry Rot fungus renders the timber dry & brittle, causing it to crumble easily into powder.  Dry rot has the ability to transport water and cause decay in otherwise drier timber.

There are many fungal species collectively known as Wet Rot. In general, Wet Rot is more localised than Dry Rot & requires a sustained higher moisture content. The most common form of Wet Rot, known as Coniophora Puteana or Cellar Fungus, can send out strands superficially over damp plaster and brickwork – however it requires much more moisture to do so & is therefore considered to be a ‘local’ fungus.

McGuinness Building Preservation Ltd has decades of experience in dealing with large & small outbreaks of Wood Rot in all types of properties. 

Treatment

We offer our clients a full range of services including a comprehensive survey to identify the damp source & affected areas, treatment of affected areas, resin repair of affected timbers & a full reinstatement of finishes.

A typical treatment of Wood Rot involves considerably more work than the simple spraying of timber with a wood preservative. To fully eradicate a fungal attack & to provide long lasting protection against re-infestation requires a comprehensive scheme of chemical treatment along with a carefully detailed programme of associated building work.

Treatment is extended in all directions from areas of known infestation, the extent of the treatment being governed by the detectable growth of the fungus and the pattern of moisture present which could support the spread of the attack. It is essential that the building work should include the rectification of the ingress of moisture responsible for the attack & the replacement of any structurally weakened timber with treated timber.
