Woodworm, dry rot, and wet rot are the most damaging of all problems buildings can experience. They damage the fabric of the building itself as well as the contents and decorations.

Timber treatments should be applied correctly for them to be successful and effective. Our skilled technicians manage treatments that cure these timber problems. They will use insecticidal and fungicidal remedies on affected surface.


When timber comes in contact with damp walls, it becomes vulnerable to fungal attacks.

The fungal decay usually starts in timber with a high moisture content. It spreads rapidly through the exposed wood and removes its integral strength. This will lead to floor movement and could eventually lead to collapse.

Dry Rot

Dry rot-type infections are more aggressive than wet rot. They can spread easily through masonry in search of fresh timber.

The usual fungal activity found in homes under floorboards are:

• Wet rot (Coniophora puteana)

• Several forms of cellar fungus

• Brown rot and/or dry rot (Surpula lacrymans)


Accurate identification and treatments are essential. Incorrect action can result in ‘stress flushes’ of rapidly increased activity.

The following are symptoms of dry rot:

• The wood shrinks and cracks in a distinctive pattern

• Grey skin tinged with lilac and yellow forms under dryer conditions

• Cotton wool-like structures develop under more humid conditions, often with ‘teardrops’

• Fruiting bodies appear as bracket or pancake shapes with a distinct orange color. Rust colored spores can be seen nearby.

• Active decay gives rise to a musty, damp odour


Insect attack causes the destruction of timber by burrowing or laying eggs/larvae in fresh timber. The formation of a tunnel network in the inner timber results in eventual failure and collapse.

In the UK, the most common infestations are:

• Woodworm

• Deathwatch beetle

• House longhorn

• Wood-boring weevils

The woodworm (Anobium punctatum) is the most destructive. They have the ability of sustained flight and can lay up to 60 eggs in any unprotected timbers of your property. This makes early treatment vital for the protection of your home.
