7 Steps to help reduce condensation and mould in rented properties

By EnviroVent Jul 24, 2021

Preventing mould in your rented property is often simpler than a cure – reducing the amount of mould and mildew that can grow makes removal simpler and less expensive to manage.

If you are running social housing, or simply renting properties out, helping your tenants to avoid condensation problems is important, as condensation can lead to damp which is expensive to repair, and mould which can be damaging to health.

The most important factor in reducing the presence of condensation is good ventilation – allowing air to move easily though a property reduces the ability of condensation to form which will, in the long term, reduce the risk of damp and mould. 

Essential tips to help reduce condensation for tenants

1. Limit the amount of moisture

Encourage residents to reduce the amount of moisture that they create in their home.

Provide advice about cooking with the kitchen door closed and using pan lids.  Preventing steam from escaping from the kitchen means that it cannot settle elsewhere in the property, and also reduces the amount of energy used when cooking which can contribute to lower bills.

It is also important to avoid drying clothes indoors, especially on radiators in bedrooms where they can release a lot of moisture that will often lead to mould growth behind wardrobes and under beds where the air can become stale.

2. Remove excess moisture

Reducing the amount of water vapour produced is the first step, but it is also important to look at ways to remove excess moisture when it has been released.

Encourage residents to wipe down moist surfaces such as bathroom walls, kitchen cupboards and bedroom windows so that the water does not have a chance to soak in.  This simple step can be hugely helpful in reducing the overall amount of moisture that is present.

Improving airflow is good.  Keeping windows open lets fresh air circulate around the house and helps to lower the chances of condensation forming.  Avoid placing furniture such as cupboards and wardrobes right up against the wall – leave a five-centimetre gap to allow air to circulate.

3. Ensure there is enough ventilation

Having fresh air circulating throughout your property is an important step in reducing mould.  EnviroVent’s PIV units are a permanent solution for this. They are placed into a loft or attic space, the fresh air that stays in the loft is sucked into the PIV unit, filtering it and sending it down through a discreet diffuser within in the living space; this dilutes the dirty air with clean air and over time, the air in the property will start to become fresher.

4. Prevent the property getting too cold

Condensation is more frequent in cold weather as there are more cold surfaces for condensation to form on, and the ability of the air to carry moisture is lower.  Advise residents to use their heating sensibly to keep the cold out and to maintain warmth that will help to keep moisture in the air and away from walls and windows.

5. Improve the ventilation system

If you have limited time to run a property, improving the ventilation can be a real blessing.  Rather than needing to keep on top of your residents, good ventilation can minimise the presence of condensation and ultimately prevent damp and mould developing.

Modern whole house ventilation systems such as Positive Input Ventilation (PIV) are centrally located in the loft or a cupboard in flats, and use very little energy, but improve air flow throughout the entire building.  Some systems include automation and can be managed remotely through your smartphone to get information about moisture levels that allows you to take action when needed.

6. Treat any mould quickly

Regular checks for the presence of mould mean that treating it is easier.  Ask your tenants to let you know immediately if they find mould in the property so that you can arrange treatment.  The mould can be dangerous to health if not treated quickly, and also, if it is allowed to develop into larger colonies, it can be much more difficult to eradicate.

If mould has developed, start by removing the mould that is on the surface of the wall or ceiling before treating the area properly with fungicidal chemicals or an anti-mould or mildew spray.  To prevent mould spores from developing, ensure that any nearby fabrics are also treated as this prevents new colonies from spreading around the property.

7.  Invest in a permanent solution

If they are allowed to develop, problems with mould and damp can be difficult and expensive to treat.  You can encourage your residents to do their part in reducing condensation, but to protect your investment in a property, it is important to take steps to prevent damp from building up.

Investing in a permanent ventilation solution such as PIV and placing modern, low maintenance extractor fans in wet rooms such as bathrooms and kitchens is the best way of preventing damp and mould in the long term
