Damp and Wood Rot Problems

In the UK, thousands of households have been afflicted by damp. Research indicates 4% of England’s 23-million dwellings are suffering from rising damp or other forms of moisture in one or more rooms.

The UK’s wet and chilly climate contributes to timber decay, but the kind of building materials also matters. Older homes may be more prone to dampness, yet it can affect new constructions as well.

Inhabiting a moist house is not only uncomfortable, but can also be hazardous to your wellbeing. Mould development may lead to diverse signs, such as clogged noses, wheezing and soreness of the eyes or skin. Moisture buildup in dwellings is risky for kids, seniors and those with respiratory or dermal issues.

Causes of Wood Rot and Fungal Decay

The principal cause of wood decay is an excess of moisture in buildings and structures, providing an ideal environment for rot fungus to flourish.

Fungi are categorised into two varieties: wet and dry rot. Wet rot necessitates a higher humidity level to survive; it flourishes on wood with fifty percent or greater moisture, while dry rot requires twenty to thirty percent.

There are many kinds of wet rot fungi, but only one type of dry rot fungus. Knowing the difference between them is the first step in effectively eradicating the rot problem.

Dry Rot VS Wet Rot:

What Is Wet Rot?

Wet rot, as its moniker suggests, necessitates a higher moisture content in wood than dry rot. It germinates when the humidity of timber or other absorbent surfaces reaches around 50%, while even 20% is enough for dry rot to proliferate. Generally, external seepages or water incursions from guttering, downpipes, stone pointing and plumbing supply the requisite high levels of dampness for wet rot’s proliferation.

To prevent a return of wet rot, the building should be checked and any leaks fixed before tackling the rot. Once dryness is restored, wet rot will cease to develop. In most cases, the timber in the damaged region must also be substituted.

What Is Dry Rot?

As previously noted, dry rot needs around 20% moisture content in wood to begin developing. Contrary to its name, it does not thrive in arid conditions.

In humid places, dry rot is common. An early indication of this issue can be condensation on windows. To avoid moisture accumulation, ensure your home has enough ventilation if you live in a damp environment.

Moisture can enter your home through a leak or damp decay and must be identified and eliminated before treating any fungal growth.

Dry rot is frequently encountered behind walls or beneath flooring, unseen. Unless identified promptly, it can inflict serious damage to timber and spread throughout the residence.

A surveyor should be consulted to determine the full extent of dry rot damage, and it is likely that plastering will have to be removed for closer inspection. Subsequently, any susceptible wood needs replacing just as if it was wet rot.

Distinguishing Wet Rot from Dry Rot

Dry rot is a serious matter which needs to be addressed immediately. It is an insidious form of decay that spreads from the source of moisture and devours wood as well as other construction materials.

Wet rot fungus is more common than dry rot, though it affects a smaller area. Generally, the timber closest to the source of moisture deteriorates first. Nonetheless, wet rot should not be disregarded as if left untreated it can result in serious structural damage.

The fungus Serpula Lacrymans causes dry rot, the most destructive form of fungal decay in structures. It can spread quickly throughout a building and cause extensive damage. Any exposed timber with a moisture content higher than 20% is susceptible to attack – something easily achieved in any home.

Poor internal plumbing and penetrating moisture resulting from faulty render, guttering or downpipes can lead to wet and dry rot. This type of rot can cause substantial damage before a homeowner is even aware of the issue, as it may proliferate between wall coverings and beneath flooring.

Identifying Wet Rot

On wood, a black mould may form.

The wood is likely to feel spongy and mushy when touched, due to discoloration.

If the rot has dried out, the wood will easily break and fall apart.

The paint may look in good condition on the front, but it could be decaying from behind, indicating the presence of wet rot fungus which will damage the finish.

Identifying Dry Rot

Fissures traverse the timber, and white filaments (mycelium growth) are often present.

When the fungus is exposed to light, it acquires a lemony yellow tinge.

The wood will turn a deep brown hue and become brittle due to dry rot gnawing away at it.

Most of the time, the damage is limited to wood; however, in certain cases, large flat mushroom-like fruiting bodies can swiftly expand through coatings such as plaster or paint.

Is Dry Rot More Damaging Than Wet Rot?

Dry rot is the most hazardous form of fungal decay in a property, as it quickly spreads and harms much of the wood. In comparison, wet rot fungus is more frequent yet not so severe; mainly appearing in areas where the wood stays moist.

Is Living in a Home with Dry Rot Safe?

Dry rot is one of the deadliest wood fungi, not only for your building’s structural soundness but also due to the dampness that it indicates. While dry rot does not cause health problems itself, it can lead to costly structural damage which could subsequently become a health hazard.

The Value of Wood Rot Treatment

It is essential to differentiate between the two forms of rot, as if left neglected they can lead to substantial structural issues.

Moisture-loving fungi can damage wet wood, breaking down cell walls and consuming the nutrients. If left untreated, this can be a major hazard to your home’s construction as it will reduce the timber’s structural integrity.

As wet rot advances, the wood loses its strength and in certain cases can become very hazardous; not just for particular components of the property such as window frames, doorframes and ceilings but also possibly the entire timber structure of the building if left untreated.

If you think your house has wood rot, we’d be pleased to help. The earlier the issue is addressed, the less expensive it will be to repair. It’s wise to call in a surveyor if you suspect wet or dry rot. For advice and aid with wood rot, please get in touch with Brighton Damp Treatments on 01273 920588.

Treating Dry Rot in Your Home

Dry rot is the most destructive of all building defects. It should be examined by an expert and addressed immediately to prevent further destruction.

To treat dry rot, the following steps should be taken:

1. identify the source of moisture;

2. remove any affected timber;

3. use fungicides to stop further spread.

Identifying the source of moisture is key when treating dry rot. Affected timber must then be removed before using fungicides to prevent further spread.

A qualified dry rot surveyor will inspect the property to identify the cause of dampness.
The surveyor furnishes precise particulars on how external blemishes or other elements are influencing the damp issue.

The technicians will remove all fungal decay on the wood.

Fungicide treatment for dry rot will be applied to the affected area.

To ensure better air circulation throughout the house and avoid dry rot, underfloor ventilation will be fitted.

Treating Wet Rot in Buildings

To combat wet rot, these steps are suggested:

1. Locate the source of moisture

2. Remove and discard affected wood

3. Treat remaining wood with a fungicide

4. Allow for thorough drying

5. Replace any removed pieces.

A property care specialist must carry out a comprehensive inspection of the premises and identify the cause of dampness.

The surveyor will then explain what’s causing the moisture – whether it be penetrating damp or condensation.

Replace any timber affected by damp rot with fresh wood.

Subsequently, an application of wood hardener and preservative should be made to the surrounding area.
