Leak to dry to treated, one company in Coulsdon
Coulsdon's housing runs from Victorian and Edwardian cottages around the old village to large stretches of 1930s semis and interwar estates climbing the North Downs slopes. Solid brick older properties and cavity-wall inter-war homes each trap moisture differently, and the hilly, clay-heavy ground brings damp problems that ordinary ventilation upgrades rarely solve on their own.

Common causes of mould in Coulsdon homes
Bay windows and cold spots in 1930s semis
Coulsdon's rows of 1930s semis, common around Woodcote and Smitham, often have single-glazed or poorly sealed bay windows and thin external walls at the front elevation. These become cold bridges where warm, moist household air condenses overnight, leaving black mould around window reveals, curtain rails and behind sofas pushed against outer walls. Refitting seals and improving airflow stops it recurring.
Solid brick cottages in Old Coulsdon village
The older cottages and terraces around Old Coulsdon's high street predate cavity wall construction, so solid brick allows penetrating damp straight through during driving rain from the exposed downland location. Mould then appears on chimney breasts, internal wall corners and ceilings below poorly maintained roof valleys. Repointing, checking flashing and treating the wall internally are needed alongside any redecoration.
Hillside properties and ground floor damp
Many Coulsdon homes sit on sloping ground towards Farthing Downs and the surrounding chalk and clay hillsides, where water run-off and a fluctuating water table push moisture into ground floor rooms and under-stairs cupboards. This shows as musty smells and mould growth behind furniture and inside fitted wardrobes long before it is visible on open wall surfaces, so drainage and damp-proofing checks matter as much as surface treatment.

Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.
