Leak to dry to treated, one company in Longfield
Longfield's housing runs from Victorian and Edwardian cottages around Longfield Hill to 1930s semis, post-war estates and newer developments in New Barn. Solid brick walls, ageing cavity fill, uPVC replacement windows and tightly sealed modern extensions all trap moisture differently, which is why mould here rarely has one single cause or fix.

Common causes of mould in Longfield homes
Solid-wall cottages in Longfield Hill
The older brick cottages around Longfield Hill and Nurstead were built without a damp proof course or cavity, so groundwater and driving rain move straight through solid walls. This penetrating damp shows up as black mould at skirting level, around chimney breasts and on north-facing external walls, and it keeps returning until the actual water entry point outside is traced and sealed.
1930s and post-war semis with poor ventilation
Many Longfield and Hartley semis had original chimneys blocked and single-glazed windows swapped for sealed uPVC units, cutting off the background airflow the houses were designed around. Bathrooms and bedrooms with no extractor, or one that is never used, build up condensation overnight, and mould develops on cold external walls, ceiling corners and behind wardrobes pushed against outside walls.
New Barn's newer, airtight homes
Newer estate housing in New Barn and around Fawkham is built to modern airtightness standards, which keeps heat in but also traps humidity from cooking, showering and drying laundry indoors. Without extractor fans actually being run, that moist air settles as condensation on cooler surfaces, so mould appears in en-suite bathrooms, behind sofas and beds, and inside fitted wardrobes on external walls.

Jensen B, via Google
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.
