Indoor mould can trigger coughing, wheezing, allergies and can worsen asthma or existing lung conditions, especially in children and vulnerable adults. Long‑term exposure to visible mould and damp is strongly linked with poor indoor air quality and recurring respiratory symptoms.

Most mould problems are caused by excess moisture from condensation, leaks, penetrating damp or inadequate ventilation in our cool, wet climate. When humid air meets cold surfaces like external walls, windows or ceilings, it creates the damp conditions mould needs to grow.

Small, light surface patches can sometimes be wiped away, but many DIY methods fail to treat hidden spores or the moisture source, so mould quickly returns. Professional remediation uses specialist cleaning agents, filtration and safety controls to remove contamination more thoroughly and safely.

A technician first inspects and surveys the affected areas to find the extent of contamination and the moisture source. They then contain the work area, remove or clean affected materials using HEPA filtration and antimicrobial treatments, and advise on moisture control to prevent regrowth.

Professional mould removal services are commonly provided across South Wales, including key areas such as Cardiff, Newport, Swansea and nearby towns. Coverage often extends to surrounding valleys and communities, so most local homes and landlords can arrange a visit.

The only way to prevent mould returning is to control moisture by improving ventilation, fixing leaks and tackling condensation or damp problems. After remediation, ongoing humidity control and regular checks of at‑risk areas help keep surfaces dry and mould‑free.
