Leak to dry to treated, one company in Borough
Borough's housing mix runs from converted Victorian warehouses and railway arch conversions around Bankside and Snowsfields to dense ex-local authority blocks near Elephant and Castle and Newington. Solid brick walls, low ceiling heights in loft conversions, and flats sitting hard against railway viaducts all restrict airflow, trapping moisture and giving black mould a foothold in older Borough properties.

Common causes of mould in Borough homes
Warehouse and railway arch conversions trapping moisture
Many Borough flats near London Bridge and Snowsfields occupy converted Victorian warehouses and arches with thick solid brick walls and exposed structural beams. These buildings were never designed with cavity insulation or vapour barriers, so warm moist air condenses directly on cold internal wall surfaces, producing persistent black mould around window reveals, corners and behind wardrobes pushed against external walls.
Ex-local authority blocks with poor ventilation
Estates around Elephant and Castle, Newington and The Blue include 1960s and 1970s concrete blocks where original extractor fans are often broken or undersized for modern occupancy. Bathrooms and kitchens generate steam with nowhere to escape, so it migrates into bedrooms and hallways, settling as mould on ceilings and around window frames, particularly in flats with single-glazed units still awaiting replacement.
High-density flats and furniture pressed against damp walls
Borough's compact conversions and new-build blocks near Bankside and Guy's Hospital leave little space between furniture and external walls, restricting airflow. Beds, sofas and wardrobes pushed tight against colder elevations trap condensation behind them, causing hidden mould growth that residents often only discover once fabric or plaster is visibly stained, by which time the moisture source needs proper investigation.

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.

Was lovely working with the team and they did a fantastic and quick job to get all the mould out of my bathroom. Very much looking forward to working with them on other projects around my house!! Thank you for everything and shout out to Karim for being so sweet!
