Leak to dry to treated, one company in Watford
Watford's housing ranges from Victorian and Edwardian terraces in Oxhey and Callowland to 1930s bay-fronted semis near Nascot Wood and Cassiobury, postwar estates in South Oxhey and Woodside, and new-build flats around the town centre. Solid brick walls, ageing extractor fans and airtight modern glazing each trap moisture differently, giving mould plenty of opportunity.

Common causes of mould in Watford homes
Solid-wall Victorian terraces in Oxhey and Callowland
Many terraced houses in Oxhey and Callowland were built without cavity walls, so rain driving against the brickwork travels straight through to the inside face. This penetrating damp shows up as damp patches and black mould on external walls, especially in ground-floor rooms and behind sofas or wardrobes pushed against outer walls where air cannot circulate.
Bay windows and cold bridges in Nascot Wood and Cassiobury semis
The bay windows and single-skin brick reveals common on 1930s semis around Nascot Wood and Cassiobury create cold bridges that attract condensation. Moisture beads on the glass and window frames overnight, soaking into plaster and timber, and black mould spreads across reveals, curtains and bedroom ceilings where these houses' original loft insulation was never upgraded.
Poor ventilation in South Oxhey estates and town centre flats
Postwar estates in South Oxhey and Woodside, alongside newer flats near the town centre and Riverwell, often rely on small mechanical extractor fans rather than natural ventilation. When these fail or residents skip using them, steam from cooking and showering has nowhere to go, and mould takes hold in bathrooms, on north-facing bedroom walls and behind fitted wardrobes.

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.
