As well as being an unsightly problem, mould on walls can be an indicator of a much more serious problem within a property and should be investigated thoroughly.

Mould is most commonly found in damp rooms like kitchens and bathrooms but may also appear in other rooms. Mould on bathroom and kitchen windows can often be caused by condensation while black mould on walls and ceilings can indicate the presence of rising or penetrating damp.

Although mould is often obvious to see as discolouration and black spots on the wallpaper or paintwork mould can also grow inside or behind walls and small signs on the surface can be the signs of a much larger infestation behind it. A musty smell and increased allergic reactions can also be signs of mould within a home.
