combatting condensation and mould
Welcome to our tenant’s guide on combatting condensation and mould, two familiar foes in many rented (and owned) homes across Leicester.
The good news is they are both relatively easy to deal with and prevent from becoming a problem.
We’ve used our 30+ years of experience in lettings to provide practical advice, clear explanations and proven remedies to condensation and mould problems.
Understanding the causes, identifying problem areas and implementing effective measures are crucial steps in successfully addressing these issues.
It’s also important to remember that pretty much every home in the UK, due to our climate, gets a degree of condensation and – to a varying degree – mould.
Our guide is designed to be a helpful resource, providing easy-to-follow advice, from identifying high-risk areas in your home to adopting long-term strategies to combat condensation and prevent mould growth.
We treat our tenants with courtesy and care, and this guide, like everything we strive to do as an agency, has got you (and any condensation issues) covered.
Look out for our top tips on each page of this guide – a quick-fire way to stay on top of things.
In this section, we delve into what condensation and mould are, why they occur and how they can impact your rental property and your tenant’s enjoyment of it. But why is condensation a concern? When excess moisture accumulates, it creates ideal conditions for mould growth. Mould, a fungus, thrives in damp, poorly ventilated areas.
It can spread quickly, causing damage to your property and, in severe cases, potentially lead to health issues, especially for those with allergies or respiratory problems.
Condensation is when warm, moist air meets a colder surface, turning water vapour into liquid. This often happens in homes during colder months (but can occur in summer, too) when heating systems are on and windows are closed, creating a perfect environment for condensation.
An important point here is not to panic – mould that causes health problems is extremely rare. This is somethingwe emphasise to tenants.
Understanding the ‘dew point’ is key. It’s the temperature at which air can no longer hold all its water vapour, causing it to to condense into water droplets. In properties, this often occurs on cold surfaces like windows or walls. Keeping indoor humidity at a balanced level is crucial in preventing the dew point from being reached inside your property.
Recognising the first signs of condensation and mould is the first step in tackling them.
From here, we will explore how to identify high-risk areas in your property and the common causes that contribute to these issues
💡 Top Tip: Install or upgrade extractor fans, especially in kitchens and bathrooms.
Let’s identify the common places where condensation and mould are most likely to occur on your property. Understanding these areas can help landlords and tenants focus their prevention and treatment efforts more effectively.
These areas are moisture hotspots due to cooking, boiling water and bathing. Without adequate ventilation, this moisture lingers and condenses on cooler surfaces
Tucked away and often poorly ventilated, these spaces can become mould havens, especially if they are against external walls.
Condensation frequently forms on windows, particularly during cold months, leading to mould growth on sills and frames.
Often having poor ventilation and being prone to damp, these lower levels of a property are common sites for mould.
Areas behind large pieces of furniture or appliances, like fridges, that are rarely moved or cleaned behind, can be hotspots for mould.
These areas can harbour condensation and mould due to less air circulation.
By identifying these high-risk areas, landlords and tenants can take targeted action to reduce the development of condensation and mould.
Regular checks and maintenance of these areas are vital in preventing mould growth and maintaining a healthy living environment.
Understanding the common causes of condensation and mould is crucial in effectively combatting them. Here, we highlight the typical lifestyle and environmental factors contributing to these issues. Weeducate your / our tenants about these.
💡 Top Tip: Keep heating systems in good working order to ensure consistent, moderate temperatures.
Dealing with existing mould is crucial in maintaining a comfortable, cleaner property. This section provides a safe and effective process for cleaning mould from your rental. We share this process with tenants.
To be safe, wear protective gloves and googles if you feel the need to. Ensure the room is well-ventilated
Remove any furniture or items near the mouldy area. Cover anything that can’t be moved with plastic sheets
Use a mould/mildew cleaning spray or a combination of water and mild detergent. Avoid bleach as it doesn’t prevent mould from returning and can discolour surfaces. Always read the instructions.
Gently scrub the affected area with a soft brush or disposable cloth. Be careful not to brush too hard, as this can release more mould spores into the air. When finished, put the disposable cloth straight into a bag, seal it and dispose of it to remove spores from inside the property
Wipe the area with a damp cloth to remove the mould. Ensure no residue is left behind.
Dry the cleaned area thoroughly. A dehumidifier can help speed up this process.
Open windows for 15 minutes daily to reduce indoor moisture. And always read the instructions on cleaning products.
There are several quick fixes that tenants can do to reduce the risk of condensation and mould immediately.
