What is it?

What is dry rot?

Dry Rot is a type of fungus called Serpula Lacrymans. It differs from wet rot in many ways but needs moisture to grow. Dry rot does not thrive in dry conditions but may lay dormant for several years as the strands from the rot can spread through porous materials such as brickwork and the joints in stone buildings. It is often unseen as it grows behind skirtings, units or in cavity walls. Dry rot requires a lower moisture content than wet rot to thrive and is accompanied by a damp smell. It is usually found in damp dark areas and places with poor ventilation, although once it spreads it can be found anywhere in the property affected and can travel quite far. Dry Rot is identified by its web-like white strands that spread across walls and a redish, brown fungus found in badly contaminated areas. Affected timbers will appear cracked and very weak, often crumbling to the touch. If dry rot is left untreated it can cause a lot of damage to a property and may even cause structural damage where structural timbers are affected.

What is wet rot?

Wet rot is basically timber saturation with a high moisture content around or above 50%. It is easy to treat in that once the affected timbers are removed and the source of moisture ingression stopped, there should be no more wet rot. The danger is when it is left untreated as it can create a myriad of problems including structural damage.

What is woodworm?

Woodworm are not actually worms but are the Larvae of wood boring beetles. There are a number of different wood boring beetles that have the same effect on the structural integrity of the timber they infest. Basically they lay their eggs in cracks in the wood and the larvae bore their way in and feed creating tunnels that weaken the infected timber.

Signs of woodworm infestation are :

  • Small holes in the timber
  • Dust around the timbers affected
  • Weak timbers that may crumble when touched or snap easily
  • You may even see the beetles themselves

How serious is woodworm.

It is a major problem if it is left untreated and requires specialist treatment. Adult beetles emerge between May and October each year and will continue to infect surrounding areas.
