How To Fix Wet Rot Problems


The most important step in wet rot treatment is to get rid of the moisture source which allows the fungus to thrive. You can locate the moisture source using your building moisture meter.

Once located you need to rectify this moisture problem and ensure that the surrounding area is dried out.

If you do not do this properly you will have yourself another wet rot spread.

After dealing with the moisture issue you then need to work with the timber. For a small wet rot outbreak you may well only have to remove a small piece of timber which is affected.

Just simply cut it away and replace it with a new piece of wood that has been treated by fungicide treatment.

For larger problems whole timber frames may have to be removed and replaced with new treated timber.

After replacing any timber you should use a wet rot treatment chemical spray on the new timber to help ensure that any wet rot infestation has been properly eradicated.

If you do not wish to carry out the treatment work yourself then it is advisable to find yourself a properly qualified and recommended timber worker who will do the job for you in a most professional way.
