Moisture is the primary cause of wood rot. When wood becomes damp, it creates an environment that is conducive to the growth of fungi, which can eventually lead to the decay and destruction of the wood.
A bad moisture reading is anything above 20%. This is because wood that is above 20% moisture content is more likely to be damaged by fungi and other pests. The ideal moisture content for wood is between 6% and 12%. If the moisture content is too low, the wood can become brittle and crack. If the moisture content is too high, the wood can become soft and spongy.
There are several things that can be done to prevent wood rot, including:
If wood rot does occur, it is important to remove the damaged wood and replace it with new wood. Rotted wood can be dangerous, as it can weaken the structure of the wood and cause it to collapse.
