What exactly is Dry Rot and how does it occur? 

Dry Rot is an invasive and progressive wood-rotting fungi which can, if ignored, lead to significant and costly structural damage. Contrary to the name, dry rot does not grow in dry conditions which is why it is vitally important that properties are regularly maintained. Often on damp timber, Dry Rot can cause a myriad of issues and in extreme cases can cause complete structural deterioration.  

Dry Rot is a fungal decay

Dry Rot is a dangerous fungal decay that primarily affects timber due to dampness in the surrounding areas. It is often found in areas hidden away from view, such as floorboards or behind walls. Established Dry Rot will begin to show physical signs, including patches on the wall and fruiting bodies of the fungus, significant damage may have already been caused by the time these fungal fruiting bodies appear.

Caused by damp conditions

Dry Rot can occur in places of high humidity and poor ventilation, especially where condensation is common. If you spot condensation on your windows, have suffered from flooding or a leak in the past, or rarely ventilate you may be susceptible to Dry Rot.

It attacks timber and crucial  structures

Dry Rot will eat away at timber and over time significantly weaken it. When this happens in crucial areas of structure the risk of further, and much more catastrophic, damage to your property is very real. It is important to treat Dry Rot in good time to prevent its spread and the risk of collapse.

How do I identify Dry Rot


Smell can be a key indicator of hidden Dry Rot, often you may smell a musty or damp smell that penetrates a room from a certain location.


More progressed Dry Rot begins to break apart timber and walls. If timber crumbles easily or an area feels damp act fast!  


The final stages of Dry Rot are physical growths penetrating your property. From patches of orange-brown to full fungal bodies growing in the area.
