Damp and mould

Tackling damp and mould - landlords and homeowners

Here are some  practical steps you can take to keep your property safe and healthy:

Improving heating and ventilation

  • upgrade heating systems by investing in energy-efficient boilers and consider smart heating controls
  • maintain and service your boiler to make sure it's working as it should
  • install thermostatic radiator valves (TRVs) for better temperature control in each room
  • improve ventilation by upgrading extractor fans and installing trickle vents to improve airflow. Consider more advanced options like mechanical or heat recovery systems for significant improvements

Improving insulation and heat retention

  • loft insulation should be adequate, typically at least 270mm
  • wall insulation, especially external walls
  • double glazing with energy-efficient windows to reduce heat loss and condensation
  • draught-proofing by sealing gaps around doors and windows to prevent heat loss and stop moisture getting in

Addressing penetrating and rising damp

  • penetrating damp - repair of the structural issues, seal external walls, and maintain gutters
  • rising damp - consult a professional for diagnosis and treatment, sometimes involving the installation of a chemical damp-proof course

Additional considerations

  • damp-seal and fungicidal paints can be helpful to cover up areas that have been repaired, they are not long-term solutions on their own
  • air bricks offer uncontrolled ventilation that can help but also provide too much air movement
  • dehumidifiers can be useful for temporary relief but do not address the cause of the damp

Professional help

  • independent damp surveyors can assess the problem and provide tailored solutions
  • experienced and reputable damp-roofing contractors can address issues like rising damp
  • certified ventilation specialists can install and maintain ventilation systems

Ongoing maintenance

  • regularly check your property for signs of damp and mould
  • operate, maintain and service heating and ventilation systems appropriately
  • make sure your home is well-insulated and draught-proofed

By addressing these issues proactively and seeking professional advice when needed, you can create a healthier and more comfortable living environment.
