A lot of people get confused by the differentials. The outcome is still bad either way and no wants to have it or if they do admit to it, but between Dry rot and Wet rot there is difference between.
- Dry rot doesn’t grow to a huge amount of moisture and lack of ventilation unlike Wet rot. It is caused by the timber itself not being looked after properly, leaving it gradually to weaker from inside first then the outside of the timber,the colour of this tends to go to a yellowish mushroom colour and produce red like brown spore dust.
- Wet rot on the other hand grows where there is moisture touching the timber, it gives a very wet appearance and would probably come from the walls as a cause of this so check regular on your walls if it feels very wet or damp. Wet rotting break the timber from the outside to the inside.
