According to the latest government figures, an average of 3% of households in England have damp in at least one room. While that might not sound like many, England has a total of around 23 million households – which would mean almost 700,000 houses are suffering.
These shocking statistics are exactly why homeowners, landlords and housing associations need to know how to combat damp and mould. Keep reading as we discuss the different types of damp and mould and how to combat them.
Types of damp and mould
In its report on houses with damp, the government cites three types of damp:
- Rising damp, where water moves up the lower sections of a wall
- Penetrating damp, where water penetrates a building through the walls, roof or windows
- Serious condensation
Whatever the case, the moisture held in damp, porous surfaces provides the perfect environment for mould to develop. When it does, it produces allergens, irritants and even toxic substances.
According to the NHS, the spores released by mould can lead to allergic reactions, respiratory problems and even a weakened immune system. The risk is higher for babies, children, elderly people, and those who have existing problems with their skin, respiration or immune system.
How to combat damp and mould
Whether you’re a homeowner, landlord or housing manager, it’s clear that damp and mould are not something you should ignore. To combat damp and mould, it’s important to identify what type of damp you’re dealing with.
Rising damp is caused by inadequate damp proofing or a complete lack of a damp-proof course in your walls. To combat the problem, most houses require a new damp-proof course to be installed. This is a waterproof barrier at least six inches above ground level, which will stop water rising up through the ground via capillary action.
It most commonly takes the form of a pore blocking salt mixture or water repellent chemicals. Alternatively, an exterior wall coating can be used to stop water rising through external walls.
As the name suggests, penetrating damp is caused by penetration of your walls, roof or windows. To combat the issue, you need to identify where water is coming from and eliminate the root cause. This could mean repairs to your roof or windows, or it may be an issue with your external walls – such as cracked render. A waterproof exterior wall coating is an effective way to stop water getting through for years to come.
Combatting damp and mould which originates from condensation is slightly more complex. In this instance, your house may be insufficiently ventilated. Installing extractor fans in the kitchen and bathroom and opening windows whenever possible are both ways to combat the problem.
However, in some cases, this isn’t enough. That’s where a damp-proof internal wall coating can help. It stops condensation forming on the surface of walls and ceilings to eliminate the problem.
