Wet Rot, Dry Rot and Woodworm Experts

Wood is a durable material which is resistant to most biological degrade providing it is kept dry. When wood becomes wet decay occurs with the type of decay depending on the type of wood, moisture content and atmospheric conditions.

As a Company we often find Dry Rot and Wet Rot Fungii misdiagnosed due to inexperience or insufficient training.

Dry Rot

True Dry Rot Fungus (Serpula Lacrymans) is the most feared and has the most potential to harm the structural integrity of your property. After attacking its initial source of timber, it can grow undetected, for example behind wall plasters and through bricks and mortar, in search of the next timber to attack. However, this type of fungus is sensitive to temperature and atmospheric changes, meaning it requires very specific conditions to grow and therefore is not as common as Wet Rot Fungii.

Wet Rot

There are many fungal species known as Wet Rot Fungi. Some types are rarely found in buildings and others only affect plaster, while soft rots are usually found on timbers in contact with the wet ground or walls.

Although these rots are regarded as superficial, they nonetheless cause decorative spoiling and the timber may need completely renewing.     Wet Rot may also have mycelium and strands which are often misdiagnosed as Dry Rot.

Wood Boring Beetle Infestation (Woodworm)

There are many types of Wood Boring Beetles with damage ranging from minor to severe.

The most frequently diagnosed, and the beetle most commonly associated with the name Woodworm is the Common Furniture Beetle. This beetle has the capacity to damage the timbers from laying eggs on the timber where the larvae eat their way out before mating and beginning the cycle again. This type of beetle is often mistaken for the Bark Borer Beetle or Pinhole Borer Beetle which appears very similar to the Common Furniture Beetle but causes no damage to the timber.

Other types of beetle that can cause damage is the House Longhorn, which is mostly confined to the Surrey area and can cause widespread damage and the Death Watch Beetle.

Quite often we see woodworm holes which is historic due either to the timbers having previously been treated or where they have naturally died away.

Diagnosis by untrained and unqualified surveyors can lead to unnecessary or incorrect treatment which can result in spending hundreds or even thousands of pounds.

Where Woodworm has been identified as requiring treatment, it is very important that the underside of the timbers, as well as the surface are treated. Our operatives lift the boards in order to treat the joists, wall plates and underside of the floorboards. Extension lances are used to treat hard to reach areas.

The chemical we use is low odour and classed as an irritant meaning you can usually return to your property the same day.

Our Company surveyors are fully qualified in identifying the various sources of beetle infestation, Wet Rots and True Dry rot. Depending on your instructions, we will investigate the area of concern and provide a written report documenting our findings. If found necessary photos and sketch plans will also be provided. Where applicable a quotation will be forwarded together with recommendations for other specialist trades.

This is an example of the damage that Dry Rot Fungus can cause. This was growing for many years undetected under laminate overlay.
Dry Rot growing over damp masonry in search of timbers to attack
Tradesmen throwing their rubble under the floor preventing adequate air flow can also cause Timber rots to occur.
This type of fungus is commonly diagnosed as Dry Rot when in fact it is Plaster fungus (Peziza family)
Evidence of a live infestation of woodworm in the roof void.
Evidence of historic woodworm which is no longer active and does not require treating.
An example of Weevil damage. This type of beetle does not attack dry wood and the best method of preservation is to treat the cause of the dampness and dry the wood out.
Some companies have been known to water down their chemicals to offer a cheap service or scrimp on treating all the timbers. Unsurprisingly these companies are usually go out of business within a few years making any guarantee given worthless. Here you can see the timbers are lifted to treat all the timbers.
