Leak to dry to treated, one company in Keston
Keston mixes large detached houses around the ponds and common with 1930s semis, mock-Tudor infill and older cottages tucked along Commonside and Heathfield Road, many backing onto woodland or clay-heavy gardens. Older cottages often have solid brick or lath-and-plaster walls with shallow or no cavity, while detached homes frequently have cellars or crawl voids, so escaped water tends to soak deep and linger rather than drain away.

Drying challenges in Keston homes
Solid brick and lath-and-plaster walls holding moisture
The older cottages near Keston Ponds and Commonside were built with solid brick or timber-framed lath-and-plaster walls rather than modern cavity construction. Once a burst pipe or roof leak soaks these walls, water has nowhere to drain and spreads sideways through the fabric. Surface plaster can look dry within days while the brick or timber behind stays saturated, risking mould and further plaster failure if drying stops too early.
Cellars and semi-basement voids in the larger detached houses
Many of Keston's substantial detached properties around Heathfield Road and Fishpond Road have cellars, crawl spaces or under-stair voids that sit below garden level. These spaces trap groundwater and leaked water alike, and with limited ventilation they hold humidity long after a visible flood has been mopped up. Left unchecked, this creates ideal conditions for mould growth on joists, skirting and stored belongings out of sight.
Clay ground and dense gardens slowing external drying
Keston sits on heavy clay soil close to woodland and the common, meaning gardens and foundations rarely dry out quickly after heavy rain or a burst external pipe. This slows evaporation from ground floors and solid screed, keeping subfloor moisture elevated for longer than in sandier areas. Combined with mature hedging and tree cover reducing airflow around walls, affected properties need sustained dehumidification rather than a quick surface dry.

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.
