Dry Rot is a brown rot fungus, which is found on wood embedded in, or in contact with wet brickwork, or other such damp conditions. The conditions needed for proliferation are similar to that for Wet Rot. The name Dry Rot may be considered somewhat inappropriate, since like all wood-
Due to its nature, Dry Rot is one of the most serious hazards that can beset a building structure and as such is often referred to as the “cancer” of a building.
Dry Rot is very secretive; it favours dark, stagnant conditions in which to develop, because of this it is able to spread extensively before any damage becomes apparent. Thus the first signs of a major attack may often be the collapse of a section of apparently sound timber.
The fungus is capable of penetrating through brickwork, masonry and plaster in search of other areas of timber of attack.
Due to its secretive growth nature, Serpula lacrymans (the true dry rot fungus)) is capable of causing extensive damage to buildings. It is very sensitive to high temperatures and humidity, which can promote exceedingly rapid growth, up to 4 metres per annum. It can remain dormant and viable for up to 10 years, the potential for a new attack being a constant threat.
Able to grow through brickwork and plaster, Serpula lacrymans is able to transport moisture, and thus carry the attack to other areas. Affected timber becomes dull brown in colour, with deep cracks along and across the grain. Silky white cotton-

One of our team of surveyors will identify the cause and the fullest extent of the outbreak. It is essential that these factors be correctly diagnosed in order that the subsequent treatments fully eradicate the problem.
