Leak to dry to treated, one company in Purley
Purley's housing runs from large Edwardian and 1930s villas around Higher Purley and Russell Hill to mock-Tudor semis, post-war terraces and 1960s-70s low-rise flats nearer the town centre. Many interwar homes have had cavity wall insulation or loft conversions retrofitted, altering how moisture moves through the structure and leaving bathrooms, bedrooms and north-facing walls prone to condensation and mould.

Common causes of mould in Purley homes
Retrofitted cavity insulation trapping moisture
Large numbers of Purley's 1930s semis on roads like Foxley Lane and Old Lodge Lane have had cavity wall insulation added decades after construction. Where installation was poor or the cavity has bridged with debris, damp tracks through to internal plaster, showing as black mould patches on external walls and behind wardrobes and beds pushed against them.
Loft conversions and bathroom condensation
Many family houses around Kenley, Riddlesdown and Old Coulsdon have converted lofts into extra bedrooms with en-suite shower rooms, often without adequate extraction. Steam and warm moist air collect under sloped ceilings and around Velux windows, producing recurring mould on ceilings and window reveals that redecorating alone will not stop.
Solid-wall Victorian and Edwardian properties
The older villas near Russell Hill and Higher Purley have solid brick walls without a cavity, making them more susceptible to penetrating damp from failed pointing, cracked render or ageing gutters. Moisture entering the wall shows internally as damp patches and black mould, particularly on ground floor rooms and behind fitted furniture standing against external walls.

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.
