Dry rot is wood decay caused by low moisture levels within a building, commonly from poor ventilation below the floor, dampness, water leaks etc. The dry rot is a result of wood destroying fungi species that attacks and weakens unprotected timbers that have been affected by damp.


Dry rot is different from wet rot in the sense that it can travel through a building taking its own moisture supply, and can travel between plaster and brick work as well as wood. Dry rot can cause severe damage if it is not treated.

Treating Dry Rot

Treating dry rot can be quite disruptive, as locating the causing source may require floor boards to be taken up or walls to be opened up. All affected timbers will need to be removed and the damp areas will have to be dried out thoroughly.

Whilst these measures are similar to treating wet rot, dry rot treatment often needs more. If any masonry has had contact with the dry rot, they will need treating with chemicals either as a spray or an injection, as will the surrounding timbers.

Although treating both dry and wet rot can seem very disruptive, it is necessary to rectify the problems to stop any further and perhaps lasting damage. Danford Brewer & Ives will strive to make sure the job is completed as quickly and hassle free as possible.

Causes of dry rot

Dry rot is caused by a fungus called ‘Serpula lacrymans’ and is the most serious form of fungal decay in a building. These wood rot fungi are attracted to damp or moist wood.

Dry rot usually occurs at a low moisture content level of around 20% to 30% which provide the perfect habitat for these microscopic fungal spores to thrive in roofs, underfloor areas or behind wall fabrics that have poor ventilation. The dry rot fungi can multiply and spread quickly throughout the moisture-affected parts of the wood and damp enclosed spaces.

This type of wood rot in buildings can be caused by poor ventilation, defective gutters, spillages from appliances, plumbing and masonry leaks inside your building property.

How to stop dry rot

It’s important to know how to stop dry rot, in order to prevent it from spreading through your house. Leaving your timbers for too long before applying a wood rot treatment can lead to the wood fungus that causes dry rot eating through important structural supports. In a worst-case scenario, dry rot can even cause a building to collapse.

The best way to stop the spread of dry rot is to remove the damp and wet environment that the wood fungus spores need to survive. Get rid of the moisture and the fungus can’t live.

This means identifying what the reason for the damp is, and fixing it.
Visible dry rot needs to be removed entirely. Rotten wood treatment involves cutting out affected areas and then treating non-affected areas with anti-fungicide to stop any spread of the spores further into a building.

A masonry dry rot treatment is also important because spores can travel through and live in the brickwork before latching onto the wood.

What is dry rot in timber?

Timber is the name given to different types of wood that have been cut and prepared as a construction material for building.

Almost all houses and buildings will make use of some form of timber, meaning that given damp and wet conditions, most properties can be susceptible to dry rot.

Dry rot in the timber will see the wood being eaten through by the fungus, as the spores activate and then devour the material. Dry rot easily spreads from timber to timber if given the correct conditions, and you will need to enact an effective wood rot treatment quickly to counter the spread.

What does dry rot look like?

Dry rot can look different depending on the extent of the growth of the fungus and how much damage it has caused. While dry rot spores are themselves invisible, you can see the dry rot as it grows into a more fungus-like substance on the timber.

When exposed to light, the dry rot fungus appears to have a lemony or yellowish tinge look to it.

Dry rot will resemble something like white or grey cotton wool across the surface of the wood but will look mushroom-like fruiting body which reddish brown colour.

The dry rot tends to turn a brown colour and is dark in appearance. The wood fungus then causes the wood to crumble or leave deep cracks. The affected wood may break and become brittle, as the fungus spreads and eats through the timber.
