I am a Landlord and Worried About Mould and Condensation

29/08/2025
 

As Summer turns to Autumn, we have been talking to some of our landlords about how to help avoid issues with mould and condensation in their property in Crewe or Stoke-on-Trent. As a landlord in the UK, dealing with mould and condensation can be a major concern, especially with the introduction of stricter regulations like Awaab’s Law and the upcoming Renters’ Rights Bill 2025. These issues not only affect tenant satisfaction but can also lead to costly repairs, legal disputes, and penalties if not addressed promptly. At Best Nest, we understand these challenges and are here to guide you through prevention, management and cure of the problem. Here’s what you need to know and practical steps to protect your property and ensure it meets health and safety rules - 


Understanding Mould and Condensation

Mould is a type of fungus that thrives in damp, poorly ventilated environments, often caused by condensation—when warm, moist air meets cooler surfaces, creating water droplets. Common areas include bathrooms, kitchens, windowsills, and poorly insulated walls. For landlords, mould and condensation can:

  • Damage Your Property: Persistent dampness can ruin paint, plaster, and structural elements, leading to expensive repairs.

  • Impact Tenant Health: Mould can cause respiratory issues and allergies, putting you at risk of complaints or legal action, especially under Awaab’s Law, which mandates swift action on serious health hazards.

  • Affect Your Reputation: Tenants may leave negative reviews or vacate properties with recurring mould issues, impacting your rental income.

Why Mould and Condensation Occur

Several factors contribute to mould and condensation in rental properties:

  • Poor Ventilation: Inadequate airflow in tightly sealed modern homes traps moisture, especially in winter.

  • Insufficient Heating: Tenants may underheat properties to save costs, leading to cold surfaces where condensation forms.

  • Lifestyle Factors: Cooking, drying clothes indoors, or showering without proper ventilation increases humidity.

  • Structural Issues: Leaking pipes, poor insulation, or faulty guttering can introduce dampness, creating ideal conditions for mould.

Understanding these causes helps you take proactive measures to prevent problems before they escalate.


Practical Steps to Prevent Mould and Condensation

Here are actionable steps to minimise mould and condensation in your rental property:

1. Improve Ventilation

  • Install Extractor Fans: Fit high-quality extractor fans in bathrooms and kitchens to remove moist air. Ensure they meet Building Regulations and are regularly maintained.

  • Add Trickle Vents: Consider installing trickle vents on windows to allow constant low-level ventilation without compromising security.

  • Encourage Tenant Habits: At Best Nest, we regularly advise tenants to open windows especially during cooking or showering, and provide guidance in their Welcome Pack and regular emails. This helps them to take responsibility for ensuring that humidity does not build up and thus avoids damp and mould. 

2. Enhance Insulation and Heating

  • Insulate Walls and Lofts: Proper insulation reduces cold surfaces where condensation forms. Check if your property qualifies for government grants to improve energy efficiency.

  • Provide Efficient Heating: Ensure your property has a reliable, energy-efficient heating system, such as a modern boiler or electric heaters, to keep temperatures consistent.

  • Smart Thermostats: Consider installing programmable thermostats to maintain steady temperatures, especially in colder months.

  • Supply Tools: Consider providing a small dehumidifier for high-risk areas or properties with known ventilation challenges.
