Generally it is the penetration of water inside the home which is the main cause of damp. A house must be kept watertight to try and avoid damp problems.

• Any leaks, gaps or damage to roofs, windows and doors could contribute to a damp problem later on.

Water can also penetrate the home from ground level rising up inside the walls, both internal and external walls.

• Failure in a damp proof course is often a big contributing factor

• Blocked sub floor air vents can create a damp environment under floors.

 

 

Damp is a common household ailment  in many properties which can seriously damage the interior and exterior of your home as well making it wet, cold and uncomfortable to live in.

 

If left untreated, damp can cause serious harm to your home and even your health. According to the World Health Organisation’s latest research into the effects of dampness and mould, you are also at a 75% greater risk of developing respiratory symptoms and asthma if you occupy a damp or mouldy house.

 

The cause of damp varies but penetrating damp and rising damp are common problems. If you think you have a damp problem, the best thing would be to do a damp survey to find out what’s going on.

 

The different types of damp:

 

Rising damp – Rising damp is caused by moisture moving up through porous materials like bricks through capillary action. This normally occurs when the house does not have a damp proof course (DPC) installed, or it has broken. A DPC is a layer of plastic, slate, or other waterproof material placed horizontally between brick layers near to ground level. This acts as a barrier to stop moisture travelling upwards. “The most economic way of fixing a DPC,” says James, “Is to drill into the walls around ground level and fill it with a damp proof injection.”

 

Penetrating damp – Penetrating damp is caused by a problem with the exterior of your home. Spotting it is something many people do after damage has been caused slowly over time. The faults may be easy to spot or may not be where you think sometimes. For instance; your roof may be leaking, or guttering and pipes may be broken, full, causing overflowing, therefore exposing the outside walls to constant torrents of water which can run down other avenues and cause damp and damage to any kind of porous material. This includes: Bricks, Blocks, Plaster, Wood etc.

 

Make sure you have a damp proof course installed

 

Condensation damp – Condensation is normally caused by simple things we all do every day in our home such as running hot water, cooking or drying wet clothes on a radiator. All these things produce hot air heavy in moisture, which becomes trapped in your home if it’s not well ventilated. When this air settles on a cold enough surface, such as a window or wall, beads of water are formed (condensation). As James points out: “All new houses have to be built with proper ventilation systems in them, usually in the bathroom and kitchen to avoid mould growing because of condensation.”

 

Dryrot/Wetrot

 

The term dry-rot came from the belief that the fungus is able to transport moisture from a source many metres away, to attack dry wood. In fact, although the fungus can transport moisture over several metres, it cannot transport anywhere near enough moisture to attack wood that is otherwise dry.

Spotting damp

If you have a damp house, walls might feel wet and cold to the touch or you may see watermarks on the ceilings or walls caused by salt deposits. With rising damp, the moisture rises up by capillary action and carries with it salt, which is hydroscopic (it attracts moisture which, along with oxygen, can cause erosion). This can cause major damage to plaster work.

 

Sometimes damp can result in moss or mould growing on your walls or ceilings and even on furniture and curtains. A good way of spotting penetrating damp is to look for green moss outside your home. Anywhere you see green moss growing, for instance in the junction at a gutter, indicates fresh water running.

 

Damp can cause mould and cracking

 

 

 A LITTLE DAMP ADVICE

 

• The Property Care Association (previously known as the British Wood Preserving and Damp Proofing Association) recommends that you hire a damp specialist to diagnose and treat damp. Check that they have been awarded the certified surveyor in remedial treatment (CSRT) qualification. A damp proofing specialist will be able to carry out a damp survey on your home.

• Check out the exterior of your home. Make sure your gutters and downward pipes are not obstructed and that water can flow freely. Look carefully to see whether there are any cracks in the rendering and check that the drip grooves underneath your windows aren’t blocked.

• Make sure that your roof is in good repair and that there are no leaks or broken tiles.

• Ensure that your home has a damp proof course installed at around 150mm above ground level.

• To avoid damp caused by condensation, do not dry clothes on radiators and keep your home heated to a constant temperature when it’s cold to keep the walls warm.

• Always use extractor fans if you have them, particularly in the kitchen and bathroom.

• You can also buy a portable humidifier to suck up moisture from the air, keeping the relative humidity in your home at an ideal 65-70%.

• To check for signs of damp in your home you could invest in a damp detector – there are many of these hand held devices available on the market.
