Dry rot will only affect timber that is damp, typically affecting timber with a moisture content in excess of 20%. For this reason, removing the source of moisture should always form the core of any dry rot eradication strategy.
Timber can become damp for a number of reasons. Among the most common causes are leaking washing machines, shower trays, baths, condensation etc…
The dampness can also come from outside the building, by for example, leaking gutters, rising damp or penetrating damp. Whatever, the source of the dampness, this must be rectified first.
Dry rot, Serpula lacrymans, is the most serious form of fungal decay of timber in properties. It can spread into and destroy much of the timber.
If you believe that you have a dry rot outbreak at your property then you must consult a specialist such as InsituSCP as soon as possible. The longer that you leave it the more costly it is likely to be to treat it.
Wet rot occurs more frequently but is less serious. Decay is typically confined to the area where timber has become and remains wet.
The Dry Rot Life Cycle consists of four main stages, each with their own tell tale signs that can help you identify a dry rot outbreak.
• Mycelium Growth – mycelium growth will typically appear as a white or grey cotton wool like substance
• Fruiting body (Sporophore) – resembling a soft, fleshy pancake or bracket with an orange-ochre surface. The surface has wide pores.
• Affected Wood – will develop large cuboid cracking and lose its structural integrity
• Dry Rot Smell – active decay produces a musty, damp odour
When controlling dry rot it is essential that the necessary steps to eliminate the source(s) of moisture causing the decay are carried out as part of the overall specification of repairs. This should be carried out by a specialist contractor.
Particular emphasis should also be given to efficient ventilation, particularly of subfloors and roof voids.
