Leak to dry to treated, one company in Norbury
Norbury's housing runs from bay-fronted Victorian and Edwardian terraces along London Road and the side streets off Green Lane to 1930s semis around Pollards Hill and blocks of converted flats and bedsits nearer the station. Solid brick walls, ageing single glazing and homes split into multiple lets all limit ventilation, so moisture builds up fast and mould follows.

Common causes of mould in Norbury homes
Solid-wall Victorian terraces losing heat and trapping moisture
Many of Norbury's terraced houses off London Road and Craignair Road have solid brick walls with no cavity, so internal surfaces run cold and condensation forms readily on north-facing bedroom walls and behind wardrobes pushed against external walls. Original sash windows add draughts but poor seals, so residents heat unevenly and moisture settles, leaving black mould patches that return each winter.
Converted flats and HMOs with restricted airflow
Norbury has a high proportion of houses split into flats and shared lets, particularly around Norbury Park and the station. Multiple occupants generate cooking and bathing steam that a single extractor fan cannot clear, and shared hallways with sealed windows trap humid air. Mould commonly appears in bathrooms, on bedroom ceilings, and around internal doorframes where airflow between rooms is cut off.
1930s semis with dated extensions and flat-roof leaks
The interwar semi-detached houses around Pollards Hill and Norbury Manor often carry later kitchen or bathroom extensions with ageing flat roofs and poorly pointed brickwork. Slow leaks around these junctions and window reveals let water track internally for months before staining appears, feeding penetrating damp and mould that spreads across ceilings and corners long before the original leak is traced and fixed.

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!
