Dry rot is the most serious form of rot to affect timbers, it is caused by a fungus called Serpula Lacrymans and famously affects buildings and ships.
This rot has the ability to not only attack the timbers within a property but also other building materials and has the potential to quickly cause devastating damage to properties with repairs costing a fair amount of money.
Dry rot does not discriminate between new and older properties DH Damp Proofing & Plastering have seen cases in all ages of properties across London & Berkshire. Dry rot occurs when there is moisture ingress into a property that can be a result of rising/penetrative damp or condensation.
The signs that this type of rot is present in a property include a damp musty smell, obvious active decay of the timber, timber cracks in shrinks with a cuboid patter, a skin on the timber that is silky grey in colour potentially with tinges of yellow or lilac on there, fluffy growths similar to cotton wool on the timber, fruiting bodies that can be fleshy pancakes that are soft with the surface having large pores and red or rust coloured powder found close to fruiting bodies.
If you notice and of these signs you should take it extremely seriously as mentioned earlier this is a fast spreading rot and can damage other materials in the property not just timber. If not treated promptly and correctly there is the potential for the structural integrity of the property to be affected and other costly and devastating consequences.
Treating this type of rot in the right was is essential. The first imperative step would be to identify the cause of moisture ingress and to treat this to start to dry the area out and is imperative to help prevent the situation recurring.
Next any affected timbers will need to be removed and surrounding areas treated with biocide and fungicide treatments. The decaying and infected timbers needs to be isolated and replaced with pre-treated timbers.
Preventative measures should then be implemented to prevent the dry rot from returning. Air flow should be increased to prevent condensation and you should check for any potential damp issues and correct any problems that you find.
Dry rot should not be treated as a DIY project. Specialists understand the methods needed and will be able to provide the best treatment and advice.
