Both Wet and Dry rot can be detrimental to the structural integrity of your building. Wet rot is limited to the timber that has succumb to water penetration and therefore it cannot spread to adjacent timber.
Dry rot can however spread to other timber via masonry and can be harder to indentify. ​We can however solve both issues.

Wet Rot Causation and Remedies.
Wet rot is a type of timber decay that happens when wood stays in contact with damp or wet brickwork or masonry for a long time. The constant moisture allows a fungus to grow, which can soften and weaken the timber over time.
​
In minor cases, once the source of moisture is removed and the area is allowed to dry out, the fungus will usually die off on its own. However, if the problem has been ongoing or the timber is badly damaged, further repairs will be needed.
​
Typical treatment steps include:
​
-
Identifying and fixing the cause of the damp – this might involve repairing leaks, improving drainage, or increasing ventilation.
-
Removing any decayed wood to stop the rot from spreading.
-
Replacing damaged timbers with new ones that have been treated with a wood preservative to help protect against future decay.
-
Ensuring new wood is kept separate from damp areas, for example by using a damp-proof barrier.
-
Improving airflow under floors or in enclosed spaces to keep the area dry and prevent a recurrence.

Dry Rot Causation and Remedies.
Dry rot is the term used for the most serious form of fungal timber decay, scientifically known as Serpula lacrymans. Unlike wet rot, which remains confined to damp wood, dry rot has the ability to spread through both masonry and timber.
This fungus digests the cellulose and hemicellulose within wood, leaving it dry, brittle, and crumbly. Over time, this can lead to major structural instability — and in the most severe cases, even sudden collapse.
​
Dry rot thrives in damp, poorly ventilated conditions. Once established, it can travel through walls and along hidden timber structures, making early detection and treatment essential.
​
Dry rot can be easier to identify on exposed timber surfaces such as beams and flooring, where visible signs often develop. However, for concealed structural elements within walls, floors, or roofs, diagnosis can be more challenging.
​
Common signs include:
-
A musty, mushroom-like odour
-
Wood that appears dry, cracked, or crumbles easily (cuboidal cracking)
-
Fungal growth resembling cotton wool, often grey or white in colour
-
Paintwork blistering or distorting due to moisture beneath
-
Skirting boards detaching or softening
