Damp and mould
Children living in a damp home are up to 3 times more likely to have breathing problems. Damp can cause mould to grow on the walls. Mould is a type of fungus. If you have got mould at home, you will probably notice fuzzy black, white or green patches on the walls, ceilings or tiles. It might smell damp and musty.
Mould is more common in homes which need repairs. You might notice it’s more damp and mouldy in bathrooms or kitchens because of condensation from washing and cooking. Condensation happens when water in the air comes into contact with a cold surface e.g. wall or window.
Why are damp and mould a problem for asthma?
Asthma and Lung UK describe how living in a damp, mouldy home is not good for your child's asthma.
- Mould produces spores which can be breathed in. If your child is allergic to mould spores they might have symptoms like coughing, wheezing, sneezing or watery eyes. It could trigger their asthma symptoms.
- Damp and mouldy housing can put your child more at risk of other things that can make their asthma worse like chest infections, colds and flu, and rhinitis (irritated nose).
- Dust mites are more of a problem in homes that are damp and warm.
What to do if you’ve got damp and mould at home
It is best to act quickly to sort out the problem before it gets worse. You need to:
- Deal with the damp. Find out what’s causing the damp, such as leaks, or condensation from cooking, showering or drying clothes indoors.
- Report any repairs needed or leaks, or problems with mould. If you’re living in social housing then contact your housing association or local authority. If you’re renting privately, Shelter have information about talking to your landlord/landlady. They provide further advice if your private landlord won’t do repairs.
- Get support if you are struggling to keep your home warm and dry. Citizen’s Advice offer advice on grants and benefits to help you pay your energy bills and on switching energy supplier. You may be able to access support from affordable warmth services in your local area such as help with repairing your boiler if you are on a low income.
- Deal with the mould. Don’t try and get rid of any mould by yourself if you have asthma that is triggered by mould. Ask a friend to help. Get a mould removal specialist or builder in if the mould covers more than 1 square metre or if it is caused by problems with the building itself or sewage.
