Leak to dry to treated, one company in Nunhead

Nunhead's housing runs from bay-fronted Victorian terraces around Nunhead Green and Linden Grove to converted flats near the cemetery and low-rise ex-council blocks off Gibbon Road. Many terraces retain original single-glazing and solid brick walls with no cavity, so condensation gathers fast, while subdivided conversions often share one extractor fan between several rooms, letting mould take hold unnoticed.

Common causes of mould in Nunhead homes

Solid brick Victorian terraces and cold-wall condensation

The bay-fronted terraces around Nunhead Green and Ivydale Road were built with solid brick walls and little to no cavity insulation. Internal wall surfaces run cold, so warm moist air from cooking, showering and drying washing condenses on plaster before it can escape, leaving black mould spreading across ceilings, corners and behind wardrobes pushed against external walls.

Split conversions with shared, inadequate ventilation

Many Nunhead terraces have been divided into upper and lower flats, often leaving one bathroom extractor serving rooms it was never sized for, or none at all in older conversions. Steam from showers drifts unchecked into bedrooms and hallways, settling as mould on window reveals and ceiling corners, particularly in top-floor flats where the roof space traps humidity.

Hillside damp near Nunhead Cemetery and older solid floors

Properties on the sloping streets near Nunhead Cemetery and Linden Grove often sit on solid or suspended floors with ageing damp-proof courses, letting groundwater and penetrating damp track up through walls after wet weather. Combined with poor sub-floor ventilation, this raises indoor humidity and feeds surface mould on skirting boards, behind furniture and along ground-floor external walls.

★★★★★

I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.

Tip: Wiping mould off with bleach and repainting hides it for a few weeks, then it returns. Mould is a moisture problem, so unless the condensation, damp or leak feeding it is fixed, it always comes back.

Frequently asked questions

How much does mould removal in Nunhead cost?
It depends on the cause and extent. We start with a damp and mould survey at £500 to find the moisture source, then quote the treatment. Treating the surface without the source means the mould returns.
Is black mould in my home dangerous?
Black mould affects indoor air quality and is best removed promptly. We treat the mould and fix the moisture driving it, so the problem is dealt with at the cause.
Will the mould come back after treatment?
Not if the moisture source is fixed. We find and address the cause, whether condensation, penetrating damp or a leak, rather than just cleaning the surface.
Do you find what is causing the mould?
Yes. Every job starts by identifying why the mould is there, using a proper damp and mould survey, so the treatment lasts.
