In the United Kingdom, high humidity is the major source of wood problems. This can cause moisture and mould to build in ceilings, walls, and floors, affecting the wood connecting these structures.

What is Wet Rot?

Wet rot is the natural rotting of wood caused by excessive moisture. Wet rot requires wood with a moisture content of 30 to 50%, unlike dry rot, which occurs in wood with a moisture content of up to 20%.

Wet rot is caused by a fungus attracted to damp wood and feeds on it, eventually destroying it. There are many distinct types of fungus, but the most prevalent is Coniophora Puteana, often known as Cellar Fungus.

Wet rot is less harmful than dry rot since it is limited to a localised wet region and does not spread. Wet rot, on the other hand, if left unchecked, can be just as devastating as dry rot. It has the potential to weaken structural timbers and cause significant damage severely.

Do you suffer from a damp in your property?

Causes of Wet Rot

Wet rot spores are drawn to wet wood with high moisture content; therefore, it needs a source of moisture to flourish. This moisture source could be caused by various problems, such as faulty plumbing, leaking gutters, leaking roof, broken pipes, leaking washing machine, or a leaking bath or shower tray. Wet rot thrives in wood that has been exposed to excessive dampness because it causes fungus spores to germinate and proliferate, allowing them to feed on the wood and degrade its structural integrity.

Rising Damp

This type of damp occurs when moisture from the ground rises through floors and walls to approximately 1m high, generally leaving a stain line in the walls this high. Rising damp can occur in a building for a variety of causes.

The current damp proof course (DPC) may be deteriorating, sometimes due to rising external ground levels that allow the original damp proof course to be bridged; in older structures, no damp proof course may exist at all.

Penetrating Damp

If a wall is in contact with soil on the outside or the outside protective coating is damaged, moisture can penetrate the wall and raise the moisture levels inside, creating damp on the inside of the wall.

If damp walls are in contact with window and door wood frames or structural timber, this can cause wet rot to appear on the wood.

Excessive Condensation

Condensation is caused by human activities such as cooking, showering and bathing, and drying clothing inside. As a result, condensation is a major source of moisture and mould in both old and new buildings, impacting many of them.

Condensation is more common in inadequately heated and ventilated homes, and it normally gets worse during the winter months, which are referred to as “condensation season” in the industry. Condensation levels can be reduced by using a well-balanced heating and ventilation system.

How To Identify The First Signs Of Wet Rot

It is difficult to identify wet rot because it thrives in the dark, poorly ventilated spaces like cellars, lofts, roofs, under floors, window and door frames, and under steps.

The following signs of wet rot can be identified:

The affected timber has a dark brown stain.
Along the grain of the wood, splitting or longitudinal cracking occurs.
Damp, musty smell.
Wood that is moist to the touch.
Fungal growth on the wood.
The colour of the damaged area is darker than the surrounding wood.
The wood has a spongy, squishy feel to it.
When the wood dries, it crumbles and fractures.

Around the affected region, notably on door and window frames, wood gets bleached.
Paint that has been damaged or is flaking.
Shrinkage of the wood.
Take a knife and drive it into the painted wood if the paint is damaged.
The knife should come to a halt after a short distance, but if it penetrates all the way to the handle, this indicates moist rot beneath the paint.
Strands of mycelium on the wood.
The wet rot fungus does not spread widely.
In the wood, there is distortion, discolouration, and a loss of strength.

Symptoms Of Dry Rot

Wood’s Fragile Texture

Timber will begin to break down due to the high amounts of moisture, resulting in a weaker structure and a sponge-like texture. In addition, the wood and lumber will appear to be a darker tone than it was before.
Deteriorated Floorboards

One of the most problematic aspects of identifying wet rot for property owners is that many wet rot issues develop in areas that are impossible to see or reach. Often, the problems occur right under our feet and knowing the indicators of damp rot can aid in detecting the problem as soon as feasible. While your flooring may appear to be unaffected on the surface, there is always the possibility that there is a damp rot problem beneath your floorboards. Keep an eye out for any bouncy feeling while walking across your floors since this could suggest a breakdown in the wood’s structure.
Cracking wood

If you believe you have discovered a wet rot problem, a few telltale indicators will help you identify the problem. The cracking of the wood, which can be cuboidal or linear depending on the kind of wet rot, is one of the most common indications of wood rot.
Moist Odour Presence

Fortunately, when wet rot cannot be seen or felt, a moist odour may indicate a problem. Water infiltration can cause dampness in a home, and the smell of damp can lead to a wet rot problem. The odour of damp rot is sometimes described as musty,’ and the air might also feel damp. If it’s something you recognise, you’ll need to do some more research.
Growth Of Fungi

Mycelium development can similarly spread over nearby masonry to dry rot. However, compared to dry rot, the proliferation of mycelium with wet rot will be slightly limited. This is owing to dry rot’s capacity to spread to other building materials in a way that wet rot cannot. The presence of thin web-like strands spreading across the surface of the wood is a telltale sign of mycelium growth. The strands expand in search of new food sources, allowing the spread to continue.

Treating Wet Rot promptly

Wet rot fungi can infect moist wood, and the wood-destroying fungus grows by breaking down the wood’s cell walls and feeding on the nutrients. This process can be exceedingly destructive to your home’s structure, and it may cause the timber to lose its structural strength.

If you do not treat wet rot, the wood loses its strength and, in some cases, becomes severely unsafe, not only for specific portions of the property such as window frames, door frameworks, and ceilings but for the entire building’s timber structure.

That’s why it’s so important to have a wet rot treatment done as soon as possible.

I am not the type to leave a review but feel it necessary to express just how grateful my husband and I are for everything Sussex Damp Experts have done for us. We have had countless builders in that haven’t been able to fix the damp patches on our dining room wall. Straight away Steve identified that this was moisture in the air attracting to salt from a removed chimney! Jack and Robbie completed the recommended work very impressively and efficiently.

I had an excellent experience with Sussex Damp Experts from start to finish. Alex conducted a thorough woodworm survey of my loft and provided a detailed, transparent quote for the treatment. His professional and courteous approach gave me complete confidence in the company. They took exceptional care to maintain the cleanliness of my property throughout the process, laying down protective coverings and cleaning up meticulously after completing the work.
