Leak to dry to treated, one company in St Albans
St Albans mixes Victorian and Edwardian terraces around Fleetville and The Camp with 1930s semis in Marshalswick, timber-framed cottages near Verulamium and the old town, and postwar and modern estates in Jersey Farm and Chiswell Green. Solid brick walls, ageing single-glazed sash windows and shallow Victorian foundations near the River Ver all make different properties prone to condensation, penetrating damp and rising damp.

Common causes of mould in St Albans homes
Solid-wall Victorian terraces in Fleetville and The Camp
Many terraces here have solid brick walls with no cavity, so cold internal surfaces encourage condensation and black mould in corners, on north-facing walls and behind wardrobes pushed against external walls. Older lime pointing and worn render can also let damp track through the brickwork, feeding mould growth around skirting boards and window reveals in bedrooms and hallways.
1930s semis and bay windows in Marshalswick and Bernards Heath
The bay windows and single-skin extensions common on these semis create cold bridging points where mould gathers on ceilings and around frames, especially where original steel or timber windows have warped and let in wind-driven rain. Poorly ventilated loft conversions above bathrooms add trapped moisture, so mould often appears on sloped ceilings and in built-in cupboards.
Riverside cottages and old town properties near Verulamium
Timber-framed and older cottages close to the River Ver and low-lying ground sit at greater risk of rising and penetrating damp, particularly where original lath and plaster walls have no damp-proof course. Combined with limited airflow in low-ceilinged rooms, this produces persistent mould on ground-floor walls, behind furniture and in cupboards that never fully dry out between seasons.

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.
