What is Damp?
Damp is the presence of moisture in the structure of a building. It often presents itself as patches on walls, bubbling paint and rotting skirting boards. It is a common problem in homes and buildings across the UK, affecting approximately 6% of all buildings and 38% of rented accommodation.

WHAT CAUSE DAMP?
Damp is caused by water exposure which in turn can be caused by rain, leaking pipes, bad ventilation and more. Issues with damp in the home occurs when the moisture travels laterally from your external walls to your internal walls.
There are three kinds of damp: Condensation, penetrating damp and rising damp. Condensation is the most common type of damp. It is caused poor ventilation and an excess of moisture in the air.
Penetrating damp, also known as “rain penetration” is the build-up of water ingress through the walls, roof or windows. It especially effects buildings in coastal areas due to the wet and humid climate, but can occur in any part of the country. When it is wet out, the moisture penetrates tiny holes in defective brickwork, cracked pointing, blocked weep holes or defective seals. During the colder months, water can get into cracked brick, freeze, expand and then thaw, allowing more water in and gradually making the problem worse. It can occur in any building but is more common within older buildings. Once damp has infiltrated the home, cold damp spots cool the walls down and your home loses heat, leading to even more damp. Damp and humidity indoors are perfect conditions for mould to grow.
Rising damp is less common. It refers to when moisture travels up from the ground and through the walls. It is caused by bricks containing tiny tubes which effectively suck up water from the ground. When this happens, salt is washed out of the brickwork and will eventually build up, stain and crumble the walls, showing signs of wear and tear.
If you are experiencing symptoms of damp you need to investigae the source of the problem in order to use correct treatment. The incorrect treatment can exacerbate the issue as the damp and mould will quickly come back. If the source is external, you are likely to be affected by penetrating damp.

potential damp consequences
- The health implications of living in a damp home are many and varied. Prolonged exposure to indoor dampness has proven to reduce lung function and cause chronic health problems. Damp or humid conditions allow the fungus black mould to grow. Black mould can vary in appearance, depending on how serious the infection is. Black mould produces spores which allow the continuation of mould growth. These spores can cause various allergic reactions.
- If damp is not prevented, black mould can grow on your walls and ceiling. Moulds can produce toxic substances that weaken your immune system. It can also trigger asthma attacks, respiratory problems and infections, cause rashes on your skin and give you cold-like symptoms. In a worst case scenario, living in a home with mould can lead to death. Babies, children and elderly are even more sensitive to the implications of damp, as are those with a weakened immune system, such as people undergoing chemotherapy.
- Recent research also points to that living in a damp and mouldy home can cause depression. Not only does damp environments contribute to mental stress and worrying but mould toxicity, a condition that occurs when mould toxins accumulate in the body, can cause brain fog, anxiety and insomnia.
- Damp proofing brickwork on your property is therefore incredibly important.
- A wet and damp home will not only endanger your health but will also rank up your energy bills and give your home a musty smell. Another consequence of damp is wet rot. This can occur when damp is confined to one area of timber. Wet rot is known to weaken structural timbers and lead to structural damage if left untreated. The longer you go without preventing damp, the more likely you are to spend a large amount of money, trying to correct the problem.
- Not having a damp proof home can cause unsightly wet patches on your walls and black mould spots on floor and ceiling. Salt from rising damp can erupt through the paint and blow the plaster. Mould can also cause cracked tiles and warped- and off coloured walls. Having an ongoing struggle with damp, mildew and mould could bring down the value of your property.
