Mould is not just a nuisance – it’s a significant problem for property managers, landlords, and operators that can lead to structural damage, reduce property value, and cause serious health issues, including respiratory problems and allergic reactions. Worse still, mould tends to return if not dealt with quickly and effectively.
Wondering how to stop mould coming back? You need a multi-pronged strategy that combines proper cleaning, property maintenance, and advanced preventative technology. This guide covers practical tips and explains how ResiSure’s cutting-edge solutions can help stop mould returning and keep your properties mould-free for good.
1. Consider Buying Houseplants to Reduce Moisture
Houseplants can do more than beautify your interiors—they can actively improve air quality and regulate indoor humidity. Plants like peace lilies, Boston ferns, and spider plants absorb moisture and reduce the damp conditions that mould thrives in, making these ideal for keeping mould at bay and keeping properties looking vibrant!
However, houseplants must be cared for correctly. Overwatering can lead to standing water in pots, which creates the perfect environment for mould. Use pots with good drainage, avoid overwatering, and periodically clean around plant bases to ensure they remain a help rather than a hindrance in your fight against mould.
2. Stick To A Consistent Cleaning Schedule to Stop Mould Growth
A consistent cleaning routine is crucial for mould prevention as dust, grime, and organic material provide a breeding ground for mould spores. It’s important to make sure your tenants are aware of the regular tasks they should be carrying out to avoid issues.
Key areas to focus on include:
- Bathrooms: Regularly clean grout, tiles, and shower curtains where mould tends to develop.
- Kitchens: Clean around sinks, under cabinets, and behind appliances where moisture builds up.
- Windowsills: Remove condensation and clean frames to prevent mould growth. Use specialised mould-killing sprays or natural remedies like vinegar or tea tree oil for areas that show early signs of mould.
A robust cleaning schedule prevents the buildup of dirt and dampness that mould needs to thrive.
3. Eliminate Existing Mould Before Starting Prevention
It’s essential to remove any existing mould before implementing preventative measures. Start with a thorough inspection to identify affected areas. Small patches can often be tackled with household cleaning solutions, such as diluted bleach or commercial mould removers.
For porous materials like drywall, carpets, or furniture, the problem can be more complex. These materials often retain moisture and spores, meaning professional mould remediation might be necessary to completely eliminate the problem.
4. Ensure Proper Ventilation to Stop Mould
Proper ventilation is one of the most effective defences against mould. Poor airflow traps moisture, particularly in areas like bathrooms, kitchens, basements, and laundry rooms. To improve ventilation:
- Install extractor fans: These are especially effective in bathrooms and kitchens.
- Open windows and doors: This allows fresh air to circulate throughout your property.
- Use trickle vents: These can be installed on windows to provide continuous air circulation without compromising energy efficiency.
Simple adjustments like these significantly reduce the moisture levels that lead to mould growth.
5. Regulate Humidity to Stop Mould From Flourishing
Mould thrives in environments with high humidity. Indoor humidity should ideally stay between 30% and 50%, and anything higher creates conditions where mould spores can flourish.
A dehumidifier is an excellent tool for maintaining the right humidity level, particularly in damp-prone rooms like basements. For larger properties or portfolios, ResiSure’s technology provides real-time humidity monitoring across all your properties, alerting you to issues before they escalate.
6. Eliminate Leaks Quickly to Stop Mould From Returning
Leaks in roofs, plumbing, or walls create damp conditions perfect for mould growth. Regular inspections can help you spot and fix issues early.
Key signs of leaks include:
- Water stains or discolouration on walls and ceilings
- Bubbling or peeling paint
- Dripping taps or pooling water under sinks
Fixing leaks quickly not only prevents mould but also avoids costly structural damage.
7. Proper Insulation Reduces Condensation
Condensation occurs when warm indoor air meets cold surfaces, creating the moisture that mould needs to grow. Insufficient insulation is a major cause of this problem. Investing in proper insulation ensures a more consistent indoor temperature and reduces condensation risks.
Focus on insulating key areas, including:
- Walls: Cavity wall insulation can prevent cold spots.
- Windows: Double-glazed windows reduce condensation.
- Roofs and lofts: Insulating these areas prevents heat loss, which reduces moisture buildup.
Not only does insulation help stop mould, but it also improves energy efficiency – beneficial for landlords working toward decarbonisation targets.
8. Use Anti-Mould Paint Where Needed
Anti-mould paint is specially designed to resist fungal growth, making it a valuable tool in damp-prone areas. Kitchens, bathrooms, and basements are common candidates for this treatment. For optimal results, use anti-mould paint after thoroughly cleaning the surface and removing any existing mould. Some paints are also water-resistant, providing an extra layer of protection against condensation.
9. Identify Draughts and Seal Them Up
Draughts may seem harmless, but they can introduce excess moisture into your property, disrupting the balance of your indoor environment. Cold draughts can also cause condensation when they meet warmer indoor air.
Seal gaps around doors, windows, and vents using weatherstripping, draught excluders, or caulk. These fixes are inexpensive yet highly effective at maintaining a stable indoor climate and preventing mould-friendly moisture buildup.
10. Invest In Preventative Technology to Stop Mould Before It Starts
Traditional mould prevention methods have their limitations. Without regular monitoring, you may not realise there’s a problem until mould has already taken hold – by then, it’s too late, and you’ll have to take time-consuming, often costly measures to remediate the issue.
This is where ResiSure’s technology comes in to transform the way you approach property management:
- Track: Our wireless devices monitor humidity, temperature, and mould risk across your properties, taking readings every 30 minutes.
- Feedback: This data is delivered via customisable dashboards and email reports, giving you real-time insights to inform your maintenance plans.
- Prevent: By identifying trends early, you can take action to stop mould before it causes property disrepair, health issues or dissatisfaction.
ResiSure’s innovative system gives landlords, BTR operators and property managers the tools they need to be proactive, protecting both buildings and tenants’ health.

How do you stop mould returning after removal?
Simply cleaning surface mould is a temporary fix; permanent eradication requires a holistic strategy that addresses the root cause of dampness. The most effective approach involves Fixing Moisture Sources, which includes repairing structural leaks, clearing blocked gutters, and addressing rising damp. Once the building envelope is secure, the focus shifts to Improving Ventilation to ensure that internally generated moisture—from cooking, bathing, and breathing—is effectively expelled. This often involves upgrading to mechanical extract ventilation (MEV) or positive input ventilation (PIV) systems. Finally, residents must be empowered to Control Humidity levels, keeping indoor relative humidity consistently below 60% to ensure that mould spores remain dormant and unable to colonise surfaces.
Can mould prevention help property value?
Proactive mould prevention is a significant factor in protecting and even enhancing a property’s market value and long-term viability. A history of damp and mould can lead to structural degradation, such as timber rot and blown plaster, which are costly to remediate and often flagged during surveys, leading to “down-valuations.” By maintaining a dry, well-ventilated environment, landlords protect the Physical Condition and Aesthetic Appeal of the asset. Furthermore, in the current market, homes with a proven track record of being “mould-free”—supported by historical data—are far more attractive to both investors and residents. This reduces “void periods” where a property sits empty and ensures that the building remains a high-quality, high-demand asset within the social housing portfolio.
What tools help prevent mould recurrence?
Modern technology has moved beyond the simple thermometer to provide sophisticated Early Warning Systems that stop mould before it becomes visible. Humidity Sensors and Smart Hygrometers are now standard tools that provide real-time alerts when moisture levels reach a “dew point” where condensation is likely to form. These are often integrated into broader Air Quality Monitoring platforms that track CO2 levels and Volatile Organic Compounds (VOCs), offering a complete picture of the home’s atmospheric health. By using these digital tools, landlords can move from a reactive “report and repair” model to a proactive “monitor and maintain” model. This data-led approach allows for targeted interventions, such as adjusting ventilation settings remotely or advising tenants on heating patterns, long before any physical damage occurs.
