Why Mould Is a Serious Concern for Renters


Mould thrives in damp, poorly ventilated spaces. It can cause respiratory problems, allergies, and worsen asthma. For many renters, mould is a persistent problem, especially in older properties common in East Sussex. Damp conditions often stem from leaks, condensation, or inadequate heating.


Ignoring mould can lead to:


  • Health issues for occupants, especially children and the elderly

  • Structural damage to walls, ceilings, and floors

  • Reduced property value and comfort


With new renters’ rights laws, landlords must address mould quickly to ensure safe living conditions.


Understanding the New Renters’ Rights Laws in East Sussex


Recent legislation strengthens tenant protections against poor housing conditions, including mould. Key points include:


  • Landlords must keep properties free from hazards, including damp and mould, under the Housing Health and Safety Rating System (HHSRS).

  • Tenants can request repairs for mould-related issues, and landlords have a legal duty to respond promptly.


How to Identify Mould Problems Early


Spotting mould early helps prevent bigger issues. Renters should watch for:


  • Visible black, green, or white patches on walls, ceilings, or around windows

  • Musty or damp smells inside the property

  • Peeling paint or wallpaper, bubbling plaster

  • Condensation buildup on windows or walls

  • Health symptoms like coughing, sneezing, or skin irritation worsening indoors


Taking photos and documenting these signs can support repair requests to landlords.


Effective Mould Treatment Options for Rental Properties


Treating mould involves removing the existing growth and addressing the root cause of dampness. Common treatment methods include:


  • Cleaning with fungicidal solutions to kill mould spores on surfaces

  • Improving ventilation by installing extractor fans or opening windows regularly

  • Repairing leaks in roofs, pipes, or gutters to stop moisture entry

  • Using dehumidifiers to reduce indoor humidity levels

  • Replacing damaged plaster or drywall if mould has penetrated deeply


Professional mould treatment services in East Sussex often combine these approaches for lasting results.


Repairing Damage Caused by Mould


Mould can weaken building materials, so repairs may be necessary after treatment. Repairs might involve:


  • Removing and replacing mould-damaged plaster or drywall

  • Treating timber for rot or decay caused by damp

  • Repainting with mould-resistant paints

  • Sealing gaps around windows and doors to prevent moisture ingress


Landlords are responsible for these repairs under the new laws, ensuring the property remains safe and habitable.


What Renters Should Do When They Find Mould


If you rent in East Sussex and discover mould:


  1. Notify your landlord or letting agent immediately in writing, describing the problem and requesting repairs.

  2. Keep a record of all communications and take photos of the mould.

  3. Allow access for inspections and repairs but ensure any contractors follow safety guidelines.

  4. If the landlord does not act, contact your local council’s environmental health department for advice.

  5. Seek legal advice if necessary, especially if mould affects your health or the landlord refuses to fix the issue.


Knowing your rights helps you take the right steps to protect your home and wellbeing.


Preventing Mould Growth in Rental Homes


Renters can also take steps to reduce mould risk:


  • Use extractor fans when cooking or showering

  • Keep windows open when possible to improve airflow

  • Avoid drying clothes indoors on radiators

  • Maintain a consistent heating schedule to reduce condensation

  • Wipe down windows and walls if condensation appears


These habits help keep homes drier and less prone to mould.


Choosing Professional Mould Treatment Services in East Sussex


When mould problems persist, professional help is essential. Look for companies that:


  • Offer thorough inspections and moisture assessments

  • Use safe, effective mould removal techniques

  • Provide repair services for damaged areas

  • Understand the legal responsibilities of landlords and tenants

  • Have good reviews and local experience


Hiring experts ensures mould is treated properly and repairs meet safety standards.
