Leak to dry to treated, one company in Farringdon
Farringdon's housing stock mixes converted Victorian warehouses and printworks, Georgian terraces around Clerkenwell Green, mansion blocks near Hatton Garden and newer glazed apartments close to the Elizabeth line. Solid brick conversions with exposed structure often lack adequate ventilation and cavity insulation, while single-glazed sash windows in older stock encourage the condensation that feeds recurring mould.

Common causes of mould in Farringdon homes
Warehouse and loft conversions with poor ventilation
Many Farringdon flats occupy converted Victorian warehouses and printworks, prized for exposed brick and high ceilings but often lacking extractor fans or trickle vents fitted to original specification. Cooking and showering release moisture that has nowhere to escape, settling as black mould on cold external walls, around steel window frames and in corners where airflow is weakest, particularly in units without balconies or openable windows.
Georgian and Victorian terraces with penetrating damp
The terraced houses around Clerkenwell Green and St John's Street date from the 1800s, and ageing pointing, worn render or damaged roof flashing lets water penetrate solid brick walls. Once inside, damp tracks through the masonry and appears as mould blooming on internal plaster, often mistaken for condensation. Left untreated, it spreads across ceilings and behind fitted furniture pushed against external walls.
Basement and lower ground floor flats below street level
Farringdon has a notable number of basement and lower ground floor conversions, common in Clerkenwell and near Hatton Garden, where rooms sit below or close to street level. These spaces suffer from limited natural light and airflow plus a higher risk of rising or penetrating damp through retaining walls, creating persistent humidity that produces mould on skirtings, behind wardrobes and around window reveals.

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.
