Condensation and Mould Issues In Property

We spoke with Steven Stone from Stone Survey this week to discuss the challenges of purchasing a property with condensation and mould issues. Here’s what he had to say…

In the United Kingdom, a persistent issue gravely affecting the quality of living is the problem of condensation and mould. Though seemingly minor, these issues have far-reaching implications, impacting health, property values, and maintenance costs.

Condensation is the process of water vapour transforming into liquid and this predominantly appears on cold surfaces and poorly ventilated areas. It is a direct result of high levels of humidity, often caused by occupier activities such as showering, breathing, and cooking. With the generally cold and damp climate (moving into Autumn), properties are particularly susceptible if they are insufficiently ventilated, heated or insulated.

The primary consequence of uncontrolled condensation is significant mould growth. Mould thrives in moist conditions, spreading quickly and seriously affects the aesthetic appeal and structural integrity of properties. Mould can cause damage to decorations, produce an unpleasant small and will almost certainly affect property value.

Additionally the health impact of mould can be profound. People exposed to mould are at a higher risk of developing respiratory conditions such as asthma, allergies, and other chronic health problems.

The lack of stringent regulations and systemic preventative measures often worsens this issue. Mostly, the responsibility of handling these problems falls on property owners, many of whom lack the knowledge on how to combat mould and condensation effectively. 

Condensation and mould issues can be significantly mitigated through preventive strategies:

1. Ventilation: Ensure spaces are well-ventilated, especially in rooms where moisture is commonly produced, such as bathrooms and kitchens. This can be as simple as opening windows, using ventilated extractor fans, or installing a whole-house ventilation system depending on feasibility and budget.

2. Insulation: Well-insulated homes maintain warmer indoor temperatures, thereby reducing condensation due to cold surfaces. Look into wall and loft insulation options to minimise condensation incidences.

3. Temperature Control: Keeping a constant, moderately warm temperature inside the property helps prevent cold surfaces where condensation can occur. 

4. Drying Clothes: Evaporated moisture from wet clothes can contribute to high humidity, leading to condensation. Dry clothes outside or in well-ventilated areas to minimize indoor humidity.

5. Dehumidifiers: These appliances reduce the level of humidity in the air, making it harder for mould to grow.

6. Maintenance: Regularly clean and dry areas prone to condensation and mould, such as window sills, to prevent spore growth. Using anti-mould paint or spray can also help.

7. Professional Assessment: If problems persist, contacting a good RICS Surveyor can help identify underlying issues and provide expert solutions.

By implementing these practices, property owners can create healthier living spaces and protect the value of their investments.
