As mentioned, the first and most crucial part of wet rot treatment is to cut off the source of moisture. We would then make sure that the surrounding area will now dry out, it is only after this point that we can hope to eradicate the problem.
There are different stages of wet rot and therefore different levels of wet rot treatment. If it is only a small area of infestation, then the wood can simply be removed and replaced by a small piece of replacement timber. We would often use a fungicidal treatment with this method to ensure that the area does not become susceptible to wet rot again.
We have seen more serious cases where the affected area has lost the majority of its strength and stability. In this type of wet rot, we would consider removing the timber as a whole and have it replaced with pre-treated new wood that will be protected against potential wet rot fungi.
In the worst case scenario, the wet rot problem will be so bad that extensive building work will have to be carried out in order to restore the buildings structural integrity.
It is for this reason that we advise getting the problem checked out before the damage gets any worse.
