Mould can be a real bugbear for landlords, making your property unsightly and putting off prospective tenants. Our quick guide to removing mould will help get your property back into tip top condition.
What causes mould?
The most important thing when it comes to removing mould is knowing what caused it in the first place, so that once you get rid of it you won’t find it comes back.
Mould is generally caused by damp conditions, but there could be all sorts of reasons the damp is occurring. Most people think of damp as being cold, but hot, humid conditions are also a breeding ground for mould.
One of the main causes of damp is condensation, which is why you often find mould in bathrooms. If your bathroom - or any rooms in your property - aren’t properly ventilated then moisture can build up and mould can start to spread.
However, if condensation isn’t an issue for your property then you may have a more serious problem. This could be a burst pipe or damage to your property allowing rain to get in, or something harder to resolve like rising damp.
How to prevent the growth and spread of mould
Proper ventilation is the key to avoiding mould that’s caused by condensation. A good first step is to make sure you have an extractor fan installed in your kitchen and bathroom - if your property is a newer build then it will likely have them already as extractor fans are a legal requirement, but for older properties you may want to think about getting one fitted.
If your property is already suffering from damp, dehumidifiers can be used to dry things out before you start to remove the mould. Though you can’t control your tenants future behaviour, if the property is empty while you solve the problem make sure to keep it properly heated and open the curtains during the daylight hours.
You can also decorate your property in a way that will help prevent the spread of mould. Using anti-mildew paint in areas prone to mould will help prevent it from growing, while using a curtain pole that keeps your curtains set further back from the windows will make them less likely to get damp.
General tips for removing mould
When you get down to removing the mould, make sure you wear protective clothing: rubber gloves, safety goggles and a dust mask will protect you from both the mould and its spores as well as the contents of the cleaning products you use.
You should also make sure the area is well ventilated - open a window if you can, or make sure your extractor fan is turned on if not.
Mould and mildew thrive on dirt, so once you’ve removed it make sure to give your entire property a thorough clean. This will help to remove any lingering spores that may cause the problem to recur.
