Tackling Mould and Damp in Rental Properties

Mould and damp are common headaches for landlords, and if left unchecked, they can lead to serious health risks, structural damage, and unhappy tenants. Prevention is always better than cure, but when problems arise, swift and responsible action is essential.

What Causes Mould and Damp?

Damp occurs when excess moisture builds up in a property. This could be due to poor ventilation, leaking pipes, rising damp from the ground, or penetrating damp from the outside. If moisture isn’t properly managed, mould quickly follows—often appearing as black patches on walls, ceilings, or around windows.

Prevention Tips

  • Ventilation is Key: Ensure extractor fans are installed and working in bathrooms and kitchens. Encourage tenants to open windows regularly, especially after showers or cooking. Good airflow is crucial in preventing moisture build-up.

  • Insulate and Heat Properly: A consistently warm property reduces condensation. Make sure insulation and heating systems are up to standard to keep the damp at bay.

  • Fix Leaks Promptly: Regularly check roofs, gutters, and pipes to catch leaks early before they escalate into larger problems.

  • Educate Tenants: Provide guidance on how to prevent mould, such as keeping furniture slightly away from walls and avoiding drying clothes indoors without proper ventilation.

Dealing with Mould

If mould appears, act quickly. Minor cases can often be cleaned using mould removal products, but for larger problems or recurring damp, professional help may be needed. Identifying and addressing the underlying cause—whether structural, plumbing-related, or due to lifestyle habits—is crucial.

Responsibility Matters

As a landlord, you are legally required to maintain a safe and habitable property. If mould results from structural issues or disrepair, it’s your responsibility to put it right.

Stay proactive, communicate openly with tenants, and treat damp seriously—it’s not just a cosmetic issue, it’s a key part of good property management.
