It is when building design precautions are inadequate or through lack of maintenance, dampness penetrates the building. Although any indication of dampness in the lower part of the wall is often diagnosed to be ‘Rising Damp,’ condensation or penetrating damp can create this condition making it essential for expert diagnosis to be made, if unnecessary and costly procedures are to be avoided.

Below are some of the main causes of rising damp.
causes of rising damp

sources of moisture in buildingsIf structural deterioration due to rising damp or other causes of damp penetration are allowed to continue without proper treatment, it will lead to expensive damage to plaster, decorations, timber work and electrical wiring and will create an unhealthy living environment.

Sources of Moisture in Buildings:

  • Rainwater penetration
  • Water from the air, condensation
  • Rising Damp
  • Lateral Penetration

What is Dry Rot? (Serpula Lacrymans)

Dry rot fungus destroys the cellulose in timbers which poses a huge threat to the integrity of the structural timbers in your property and can cause serious safety issues. It is thought of as the most serious type of timber decay as it reduces timber to a dry and crumbly consistency and therefore requires immediate analysis by a qualified surveyor. For fungal decay to begin, it requires water to penetrate, increasing the moisture content to above 22% which allows bacteria and micro fungi to colonise in the wood, resulting in the partial breakdown of the cell structure.

How to identify Dry Rot?

  • Distinct mushroom smell
  • White mycelium growth (cotton wool like appearance)
  • Fruiting body
  • Cuboidal cracking
  • Red spores may be deposited as a layer of dust around the infected area.

How will Dampcure-Woodcure/30 Ltd cure your Dry Rot?
After our surveyors have carried out a thorough inspection, we can send our experienced technicians to the property where they will:

  • Introduce ventilation procedures
  • Re-apply our specialist plaster

We will then issue you with our 20 year guarantee and unlike many of our competitors you can be assured by our 60 year history as dry rot specialists, that we will be around in the future to honour this.

Brief History Of Dry Rot
Historical stories of dry rot date back to the early 18th century – a boat in Woolwich was in such a bad state that the deck sunk under a man’s weight, and there were orange and brown coloured fungi hanging from deck to deck.

Woodworm is a collective name for the number of species of wood boring insects.

The term woodworm actually refers to the pupa which bores through the wood. The active life cycle of the woodworm species can vary from 1 year to 14 years.

Dampcure-Woodcure/30 Ltd will carry out a professional survey on flooring timbers, where accessible and provide a detailed report for woodworm eradication.​

Woodworm treatment
Our treatment solutions are water based insecticide in accordance with COSHH.

Here are some of the more common beetles:

Common Furniture Beetle (Anobium Punctatum)
About 75% of all woodworm damage – attacks hard and soft wood. Flight hole about 1.5mm diameter.


Woodboring Weevil (Pentarthrum Huttoni, Euophryum Confine)
Usually associated with wood decayed by fungus i.e. Wet Rot leaving flight holes of ragged appearance. Around 1mm diameter.


Bark Borer Beetle (Ernobius Mollis)
Seasoned and partly seasoned softwood with bark present. Must have bark present to initiate attack. Usually no treatments with his beetle.

House Longhorn Beetle (Hylotrupes Bajulus)
Causes rapid and severe damage in softwoods, mainly in London and Surrey. Oval flight holes up to 10mm x 6mm. Less common than the others.

Deathwatch Beetle (Xestobium Rufovillosum)
Particularly damaging in old buildings where hard wood has incurred previous decay. Flight hole about 3mm diameter.

Wet Rot treatment Dampcure Woodcure Watford LondonWet Rot

Commonly known as ‘mine fungus’, it often has the same fungal characteristics as Dry Rot. There are several species so a thorough investigation is necessary for an accurate cure.

What is Wet rot?

Wet rot is a general term used to describe the majority of fungal species responsible for timber decay. There are several species of Wet Rot fungus, but all require a moisture content in wood between 40-60%. This is commonly caused in wood exposed to damp conditions for prolonged periods of time. Wet Rot fungi, whilst generally not as destructive as Dry Rot, can nevertheless cause severe damage if left untreated and is a common cause of structural defects.

How do you identify Wet rot?

Wet rot has similar characteristics to dry rot but as the mycelium is not always present which would facilitate identification, we recommend diagnosis by a qualified surveyor from Dampcure-Woodcure/30 Ltd.

Appearances can include the following:

  • Cuboidal cracking (not as severe as dry rot)
  • Mycelium – whitish/yellow at first, later yellowish/brown
  • Strands – yellowish/brown at first, later dark brown
  • Fruiting body – creamy/yellow at first, later olive/brown
  • Distortion, discolouration, softness, cracking and the loss of strength of the timber

How will Dampcure-Woodcure/30 Ltd cure your wet rot?

After our surveyors have carried out a thorough inspection we can send our experienced technicians to the property where they will:

  • Replace affected timbers and in some instances renew wall plaster
  • Introduce ways to increase ventilation and drying out
  • Apply preservative treatment

We will then issue you with our 20 year guarantee and unlike many of our competitors you can be comforted by our long history as dry rot specialists and that we will be around in the future to honour this.

Condensation treatment Dampcure Woodcure Watford LondonCondensation

Condensation is the major form of dampness affecting properties throughout the country. It is caused simply by water vapour in the atmosphere, forming water droplets.

Condensation can be seen when water droplets, for example, appear on window panes. The source of water can be attributed to various domestic activities.

Condensation can be caused by cooking, personal bathing, washing clothes and drying on radiators.

One litre of fuel burned in a portable heater releases one litre of moisture into the atmosphere and in fact normal breathing also adds significantly to the volume of water vapour present in the household environment.

Condensation can be cured by adequate heating, insulation and ventilation, all of which will control the production of condensation. Fans can be fitted to help combat this problem, which we can install.
