Peter Cox provides expert tips on how homeowners can safely and effectively tackle mould infested asbestos containing materials in their properties.
Mould can be a persistent problem for property owners and can be especially concerning when it grows on surfaces that may contain asbestos. With around two million people in England alone living in homes with significant damp or mould, the issue is widespread. Although damp and mould can typically be removed with common household products, the presence of asbestos in the home can make mould removal more complex, as the surface must not be scrubbed, rubbed or disturbed.
According to the Health and Safety Executive, mould can often be found growing on asbestos on areas such as ceilings or walls coated with Textured Decorative coatings known as Artex. When mould is found on surfaces like textured decorative coatings, asbestos cement and asbestos insulating board (AIB), it should not be disturbed, to avoid asbestos exposure, which can be far more hazardous than mould.
If you suspect asbestos containing materials are present in your home and they are affected by mould, it is important to handle the situation carefully to protect both your health and the integrity of your home.
Nicholas Donnithorne, UK technical manager at Peter Cox, shares expert recommendations for safely and effectively removing mould from materials containing asbestos to ensure peace of mind:
1. Do not attempt DIY removal
If you discover mould on surfaces that may contain asbestos, it is important not to attempt DIY removal. While asbestos that is in good condition and left untouched poses few health risks, asbestos that has been disturbed or is in poor condition can release fibres and dust that can be dangerous, causing serious illnesses like mesothelioma, lung cancer, Asbestosis, and pleural thickening over time.
For commercial properties, under the Control of Asbestos Regulations 2012, the Health and Safety Executive (HSE) advises that any work involving asbestos should be conducted by trained professionals who are competent and trained in either non-licensed or licensed asbestos management work.
2. Identify the source of asbestos
The most common materials containing asbestos in homes are Textured Decorative coatings. These are often found on ceilings and sometimes walls, in products such as Artex (before 1992). In bathrooms, bath panels may be made of Asbestos cement or Asbestos Insulation Board. In lofts, there may be asbestos containing firebreaks between properties or the ceiling and loft hatch may contain asbestos. In rare instances, loose fill asbestos insulation contained in paper bags or laid loose, may be found in lofts, between floors or within walls.
If you have mould in your property on textured decorative coatings, it is crucial to obtain professional advice before touching. If you are unsure whether your home contains asbestos, consider having a professional asbestos survey conducted to assess the risk.
3. Perform a risk assessment
Certified professionals can undertake a survey and risk assessment before considering removing asbestos. Peter Cox’s sister company DCUK are equipped with the knowledge and skillset to remove asbestos containing materials safely, ensuring that harmful dust and fibres don’t spread throughout your home, which could result in an expensive decontamination job.
4. Addressing the root cause of mould
Simply removing the mould-infested asbestos containing materials is not enough to prevent the problem from recurring. It is essential to tackle the underlying cause of the mould growth.
Water ingress, flood damage and condensation can all lead to excess moisture creating the ideal environment for black mould to grow. Be vigilant for signs of condensation and mould, which include a damp, musty smell and black specks on walls, ceilings and window sills, as well as water vapour on windows and walls.
To reduce condensation, use extractor fans (where fitted) when showering, bathing or cooking, open windows frequently to allow air to circulate freely and avoid drying clothes on radiators.
5. Seek Professional Help
If you’re unsure how to safely deal with suspected asbestos containing materials, it’s essential to call in an expert to survey the property and confirm whether there is asbestos present. A qualified professional like Peter Cox’s sister company DCUK can then be called in to safely remove any harmful materials, ensuring that your home is asbestos free and safe to live in.
6. Regular Inspections
Finally, ensure that you conduct regular inspections of areas susceptible to mould, especially after heavy rains or flooding. Keep an eye out for signs of water damage, musty smells, or visible mould spots. Early detection can save you time and money by allowing you to address the problem before it becomes a larger issue.
Dealing with mould in properties that may contain asbestos is no small task, but with these tips, you can safely tackle the problem while minimising the risk to your health. Always prioritise safety and seek professional advice or assistance when asbestos containing materials may be present.
