What is Dry Rot?

Dry rot is a type of wood degradation produced by a fungus that destroys the wood’s strength and stiffness-giving components. It was initially used to describe any fungus-caused rot of cured wood in ships and buildings, leaving the wood darkly coloured, deteriorated, and cracked.

Dry rot is a type of brown rot caused by particular fungi that deteriorates wood in buildings and other wooden structures without an obvious source of moisture. Because all wood-rotting fungus requires a certain amount of moisture to begin decaying, the name is deceptive (usually due to penetrating dampness). Dry rot fungi attack wood in the same way as other brown rot fungi do: chemically. The rotting wood develops a black or browner crumbly appearance, with cubical splitting or checking, and becomes brittle, smashing the wood into powder.

A dry rot infestation in a structure can be a dangerous infestation that is difficult to eradicate and necessitates immediate action. Significant deterioration can result in structural instability and the collapse of a building.

Dry Rot VS Wet Rot

Dry rot and wet rot have different spores; hence they have other appearances. The most significant difference is that wet rot requires a lot more moisture to propagate. This is because it can spread via capillaries. Wet rot can also spread more easily across more significant areas.

What Causes Dry Rot?

Dry rot can be caused by a variety of fungi. Serpula lacrymans is the most common in the United Kingdom. If not dealt with quickly enough, it will spread throughout your home, encompassing brick and stone, as well as plaster. This will have an effect on your house’s structural integrity as well as the integrity of your timbers.

When there is an excessive quantity of moisture in your wood, it causes dry rot. If various environmental conditions exist, such as more than 20% moisture level in your wood, dry rot spores can form fast. This will attract the fungus, which will use the wetness to absorb nutrients.

You will need a specialist survey to distinguish whether your decaying timber is caused by dry rot or a different fungus. Likewise, the treatments for similar damage will vary based on the specific cause.

Identifying Dry Rot: What are The Signs Of Dry Rot In Your Property?

You’ll need to be aware of the signs and symptoms of dry rot to spot it as soon as possible. The sooner dry rot is discovered, the less time and money you’ll have to spend addressing it. A comprehensive assessment is required if you notice any of the signs and symptoms described below.

Your Timber Is Damaged

When your timber is affected by dry rot, it becomes brittle and dry. Your wood may even disintegrate as a result of this. You’ll also notice your wood’s colour deteriorating due to dry rot. Dry rot, in particular, can lead to a condition known as cuboidal cracking. Cuboidal cracking occurs when wood splits into cubes of around 50 mm in diameter. Hyphae, a white fungal growth, is frequently found on this damaged wood. Hyphae, which resembles cobwebs, is a common indication of dry rot.

Your Timber Smells

The Dry rot smell is particularly musty. Your timbers will have a damp, fungal, murky odour if it has been impacted by dry rot. Even if you can’t see the dry rot outbreak, this can happen. However, the presence of an odour does not necessarily imply the existence of dry rot. The scent will indicate that your timber is damp. However, humidity can lead to dry rot later on.

Your Timber Has Fruiting Bodies On It

This is the most visible and ultimate stage of dry rot. Fruiting bodies that look like mushrooms may begin to attach themselves to your wood. They occur when dry rot can no longer feed on the wood, forcing the fungus to pump spores out instead.

Your Timber Has Spore Dust

Dry rot spores are not only found in wood that has been afflicted by the infection. Yet, if dry rot spores are accompanied by splotches of rusty coloured dust, it can indicate dry rot. In the final stage of the dry rot cycle, fruiting bodies emit spore dust.

The Importance Of Spotting The Signs Of Dry Rot On Time

Wood rot and dampness are two of the most devastating problems that may occur in a property; they can cause significant damage and destruction to wood and masonry and substantial disturbance and expense to remove. Stopping the source of the damp and eradicating the fungus assault are the only ways to deal with this severe wood rot problem.

Dry Rot will quickly spread throughout your home if left untreated, causing severe structural damage and requiring thousands of pounds in repairs. Each fungus spore has the potential to start a new dry rot epidemic somewhere else on your land. We are pretty thorough in our corrective work. We begin by identifying the exact source of the problem (damp) and eliminating it. The damaged timbers are cut out to beyond the last visible indication of mycelium, and the wall plaster is removed. Before replacing the woods with new pre-treated lumber and re-plastering following our specification, the walls and surviving timbers are thoroughly treated with high-performance timber preservatives.

Dry Rot Treatments and Repair

Dealing with the Source of Dampness

To solve issues with wet rot, it is crucial to identify the source of moisture and stop the cause of the damp. Depending on the cause of damp, our professionals will advise you on the best treatments available.

Fungicide Treatment

Depending on where the rot is located and the stage of infestation, an expert will treat your dry rot in a different approach. The inside of the wood will receive some treatments, while the outside of the wood will receive others. To try to prevent a recurrence, you might use a range of dry rot remedies. Boron gel can be used to cure and prevent dry rot in various quantities and concentrations.

Boron rods can also be injected and installed by a professional in your wood. These rods will go into the holes that have already been drilled. Boracol can treat dry rot in more complex situations if insects such as cockroaches are also present. After the treatment is finished, you can use dry rot repellent paint to safeguard your property from potential dry rot problems. This product contains a unique emulsion that prevents dry rot from spreading. It works on various surfaces, including wood, bricks, mortar, brickwork, and even plaster.

Boron can be a hazardous material, so it’s always best to leave this treatment to the professionals. It’s also a good idea to keep anyone vulnerable, such as your children, out of the affected area. While you can perform specific procedures on your own, most of the treatment must be done by a professional. We will be able to discover any dry rot issues and analyse the depth of the problem with the help of our damp proofing experts. This implies that we’ll be able to tailor our treatment method to your specific situation. We’re also well-trained, so we’ll know how to properly handle a biocide, keeping you safer.

Dry rot can be a severe problem that requires immediate attention. If dry rot is not treated quickly, it will spread and cause significant harm. This means that the structural integrity of your home will deteriorate over time. Please don’t put off taking action until it’s too late.
