Mould in Flats London
Mould in flats in London is a common issue, particularly in properties where ventilation is limited and moisture levels are high. If not properly addressed, mould can spread quickly and lead to ongoing problems within the living environment.
Why Mould Develops in Flats
Flats are often more prone to mould due to limited airflow, shared walls, and insulation differences. Everyday activities such as cooking, showering, and drying clothes indoors can increase humidity levels, creating the conditions for mould growth when ventilation is insufficient.
Signs of Mould in Flats
-
Black mould forming on walls or ceilings

Mould around windows and external walls

Musty or damp odours
-
Discolouration or staining on surfaces
Mould in flats is often treated as a surface issue, but in many cases the underlying cause is condensation and poor ventilation. Cleaning the mould without addressing moisture levels will usually result in it returning.

Understanding whether mould is caused by condensation or another form of damp is essential. You can learn more in our condensation vs damp guide.
A professional damp inspection ensures that the root cause of mould is correctly identified, allowing for the correct solution to be applied rather than temporary treatments.
