What is Dry Rot?

Dry rot is a form of wood degradation caused by fungi that disintegrates the strength and rigidity-giving components. Historically, it was utilised to refer to any decay of cured wood in ships and structures, making the wood darkly coloured, weakened, and fractured.

Dry rot is a kind of brown rot caused by certain fungi that weaken wood in buildings and other wooden structures, even without an apparent source of moisture. The term “dry” rot is misleading since all wood-rotting fungus needs a certain level of moisture to start decaying. Dry rot fungi degrade timber using the same chemical process as other brown rots – the rotting wood takes on a black or dark brown crumbly look, with splintering or cracking into cubes, and becomes fragile enough to be easily crushed into powder.

A dry rot infestation in a structure is dangerous and difficult to remove; thus, prompt action should be taken. Failure to do so can cause extensive damage leading to structural instability and even collapse of the building.

Comparing Dry and Wet Rot

Dry rot and wet rot have diverse spores, thus they possess distinct appearances. The key distinction is that wet rot necessitates much more moisture for propagation since it can disseminate through capillaries. Moreover, it can be spread across larger areas with greater ease.

What Is the Cause of Dry Rot?

Serpula lacrymans is the most common fungus causing dry rot in the UK. If not addressed promptly, it can spread through your home – encompassing brick, stone and plaster – impacting both your house’s structural integrity as well as that of timbers.

If there is an abundance of moisture in your wood, it can lead to dry rot. At a humidity level of over 20%, the spores form quickly and attract fungus that feeds on the wetness for sustenance.

A specialist survey is necessary to determine if your decaying timber is due to dry rot or another type of fungus. Treatment options will depend on the cause.

Identifying Dry Rot: What to Look For In Your Property

Be aware of the signs and symptoms of dry rot so that it can be detected promptly. Early discovery will save time and money in addressing it. A full assessment is necessary if any of these indications are noticed.

Protect Your Investment: Assessing Damaged Timber

When timber is afflicted with dry rot, it tends to become brittle and dry. In some cases, the wood may even disintegrate. The colour of your wood will also suffer due to this condition. Dry rot has a particular tendency to cause cuboidal cracking; when the wood splits into cubes around 50 mm in diameter. It’s common for hyphae – white fungal growth resembling cobwebs – to be found on damaged wood as an indication of dry rot.

How to Determine if Your Timber is Fresh

The musty smell of dry rot is particularly strong. Your timbers will give off a damp, fungal, murky odour if they have been affected by the fungus. Dry rot can occur without being visible; however, presence of an aroma doesn’t necessarily suggest its existence. The scent will indicate that your timber is moist – and humidity could result in dry rot later on.

Signs of Fungi on Your Timber

The ultimate and most visible sign of dry rot is the emergence of fruiting bodies that resemble mushrooms on wood. When the fungus has exhausted its food supply, it emits spores as a means of propagation.

Protect Your Timber From Spore Dust

If a rusty coloured dust is present alongside dry rot spores, it can be an indication of the infection. At the last stage of the cycle, fruiting bodies will emit spore dust.

Spotting Dry Rot Early: How To Protect Your Property

Wood rot and dampness can do significant damage to wood and masonry, as well as cause great disruption and cost to remove. The only way to deal with this issue is by halting the source of dampness, and removing the fungus.

We take dry rot seriously. If left untreated, it can quickly spread throughout your home causing severe structural damage that could cost thousands of pounds to repair. Each fungus spore has the potential for starting a new epidemic on your property. To ensure we address the problem effectively, we first identify and eliminate the source of dampness. Damaged timbers are then cut out beyond where any mycelium is visible before replacing them with pre-treated lumber and re-plastering according to our specifications. The walls and surviving timbers also receive a thorough treatment with high-performance timber preservatives.
