Leak to dry to treated, one company in Southwark
Southwark's housing stock ranges from Victorian terraces in East Dulwich, Peckham and Camberwell to converted warehouse flats in Bermondsey and Rotherhithe, post-war council estates around Walworth and Elephant and Castle, and newer riverside developments near Surrey Quays and Canada Water. This mix of solid-wall properties, tightly sealed conversions and dense estate living creates varied conditions for condensation and damp to develop, especially where original ventilation has been lost or blocked over time.

Common causes of mould in Southwark homes
Solid-wall Victorian terraces in East Dulwich, Peckham and Camberwell
Many of Southwark's terraced streets were built without cavity walls, so external walls stay cold and attract condensation once heating patterns change or a chimney breast is blocked. Black mould commonly appears on north-facing bedroom walls, behind wardrobes pushed against external walls, and around single-glazed sash windows, particularly in properties where loft or floor insulation has been added without addressing background ventilation.
Converted warehouse and riverside flats in Bermondsey and Rotherhithe
Former warehouse conversions and older riverside buildings often mix original brickwork with modern airtight fit-outs, trapping moisture indoors with nowhere to escape. Steel-framed windows and old pointing can let in penetrating damp during heavy rain, while poor extraction in compact bathrooms and kitchens leaves mould forming around window reveals, in corners of open-plan living spaces, and behind fitted furniture that blocks airflow to the wall.
Council estate flats and maisonettes around Walworth and Elephant and Castle
Concrete-framed estate blocks are prone to cold bridging at window lintels, balcony edges and external corners, so mould frequently tracks along ceiling perimeters and above windows in these flats. Where a historic roof or plumbing leak has left materials damp, or where flat roofs and parapet walls have deteriorated, mould can spread across ceilings and top-floor bedroom walls long after the original leak has been patched rather than properly resolved.
What our customers say
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.
