By the way, for your info
Slugs from different families are fungivores. That means they eat dry rot fungus!! It is the case in the Philomycidae (e. g. Philomycus carolinianus and Phylomicus flexuolaris) and Ariolimacidae (Ariolimax californianus), which respectively feed on slime molds (myxomycetes) and mushrooms (basidiomycetes).
This photo was taken on a wall under the floor in a home in Hull which was suffering from dry rot infestation. A family of slugs was found there.
Causes of damp-Leaks
Leaks are often be a major cause of damp within a home leading to issues such as penetrating damp and wet rot. Most of the time, the result of a leak will be localised to one area of a wall. If you notice localised damp patches, check the following:
Examine downpipes and guttering near to the affected area.
Look for damage, cracks, faulty joints or seals. Ensure that your drains and downpipes are not blocked. Rainwater can very easily be backed up forcing itself out of a pipe joint within the affected area. If the damp is below a flat roof, or a roof channel, check that the felt is sound. If the damp is below a window, check the window frame and windowsill. Badly fitted windows can also let damp penetrate into a room. If the damp is localised around a chimney breast, check the flashing and tiles.
Causes of damp–rising damp
If you are on the ground floor and the damp seems to be at the bottom of walls, it could be that the cause of damp is the result of your damp proof course being bridged resulting in rising damp. This could be because of an increase of ground levels around the affected damp area or that your damp proof course has failed. If it is the case whereby the damp proof course has been bridged, consider if there are any external features installed within the affected area such as a flowerbed or new patio. Could there be an excess amount of soil against the wall from some recent gardening that has
bridged the damp proof course? By simply lowering the ground level or removing any of these features and leaving the area to dry out, you could solve your rising damp issue.
If it is the case the damp proof course has not been bridged, then it could be the possibility that your damp proof course has failed meaning that you will need to consider repairing it. In this instance, we would always recommend you contact Dovedale Dampcure Services Ltd to fully evaluate the extent of the damp issue.
Causes of damp – condensation
It is not always the case whereby the cause of damp originates from the outside. One of the most common causes of damp within homes is due to condensation. Condensation occurs when large quantities of water vapour from general everyday living becomes trapped within a property.
When the warm moist damp air comes into contact with cooler air, or a surface, which is at a lower temperature, the result is condensation, this can prove ideal for the germination of the commonly associated black spot mould. The key to solving condensation however is ventilation. By simply improving the air ventilation within a property, you will generally have an impact on the amount of condensation and mould issues that you are having within a property.

Whilst out on a Woodworm and damp job at a big posh manor house in the country the owners wife asked if I wanted a cheese sarnie for lunch.
But have a look at the posh nosh that arrived! Pure quality and typical of country hospitality.
This photo shows pretty much all of the 4 stages in one shot! But you get the point, we hope. This shows a small underfloor area of the front room of a terraced house in Hull. This nasty case of dry rot had flared up due to all of the 'conditions' being just right - lack of proper ventilation, lots of timber around for the fungus to eat and a steady but intermittent water source. In this case a waste water pipe had cracked underground causing a water seepage. The water source was rectified and stopped, the fungus was killed and all of the decayed timbers were removed and relaxed by Dovedale Dampcure Services Ltd.
This final photo shows the last stage in the life cycle of dry rot - the fruiting body. The darker are of mass in the centre is that which pumps out the millions of spores to infect other areas of the property.
Hi, and thanks for taking a look at our blog page. We aim to keep you posted on all of the developments at Dovedale Dampcure Services Ltd. We'll be showing photos of damp walls, work happening shots of dry rot fungus etc. One of our aims is to keep you 'in the know' on all matters concerning property preservation. All photos have been taken on our work sites.
Photo showing one of our guys - best pose!!
This photo shows some of the spores produced by a dry rot fruiting body ready to 'infect' another part of the building.
The life-cycle of dry rot can be broken down into four main stages. Dry rot begins as a microscopic spore which, in high enough concentrations, can resemble a fine orange dust. If the spores are subjected to sufficient moisture they will begin to grow fine white strands known as hyphae. As the hyphae germinate they will eventually form a large mass known as mycelium. The final stage is a fruiting body which pumps new spores out into the surrounding air.
Take a look at the photos to the left to see the four stages of the dry rot life cycle.
Condensation is one of the most common causes of damp in the home. Condensation is caused when water vapour comes into contact with cold surfaces and condenses to form dampness or water droplets.
Air can contain varying amounts of water vapour; warm air can hold more water vapour than cold air. When warm air comes into contact with a colder surface, it cools down and can’t retain the same amount of water vapour. The excess water vapour is released and forms condensation.
Water vapour is invisible in air and is formed when you breathe and when you carry out normal daily activities in the home. It is also formed as the materials used in the home’s construction dry out. If condensation occurs over a prolonged period of time, other signs will start to appear such as damp patches on walls, peeling wallpaper and ultimately black mould growth.
Common signs of condensation:
In addition to improving the health of the homeowners who live in affected dwellings, the rewards for successfully solving condensation problems, or preventing these recurring problems are enormous - not only in maintenance costs but also in the freeing up of housing maintenance personnel who annually return to the same dwelling to deal with the same recurring problems.
What can be done to fix this problem?
The Drimaster provides ventilation for the whole property using the tried and tested Positive Input Ventilation (PIV) principle, where fresh, filtered air is introduced into the home at a continuous rate, encouraging movement of air from inside to outside. The results are a fresh and healthy indoor environment in which condensation and mould cannot exist, and where indoor pollutants including harmful Radon gas are kept to a minimum – all great news for allergy sufferers.
