Damp, mould & leak services in Hampstead
Hampstead's housing stock is dominated by Georgian and Victorian terraces, substantial Edwardian villas, purpose-built Edwardian mansion blocks and a scattering of interwar semis. Many properties retain original solid brick walls, aged slate roofs and Victorian drainage systems, all of which make them particularly vulnerable to penetrating damp, rising damp and concealed plumbing leaks.

Common damp problems in Hampstead homes
Penetrating Damp in Victorian and Georgian Terraces
Hampstead's older terraced properties were built with solid brick walls rather than modern cavity construction, meaning there is no air gap to interrupt moisture driven inward by wind and rain. The elevated position of much of Hampstead exposes these facades to significant weather, and where pointing has eroded or render has cracked, rainwater penetrates directly into internal walls, causing staining, plaster failure and mould growth.
Basement and Lower Ground Floor Moisture in Converted Villas
Many of Hampstead's large Victorian and Edwardian villas have been converted into flats, with lower ground floor units sitting partly below or at ground level. Original tanking and drainage on these properties is frequently inadequate or has deteriorated, allowing groundwater and surface water to seep through foundations and floor slabs, producing persistent damp patches, efflorescence on brick and musty conditions that are difficult to resolve without specialist investigation.
Condensation and Hidden Leaks in Edwardian Mansion Blocks
Belsize Park and South Hampstead contain a high concentration of Edwardian mansion blocks with thick external walls, communal pipe runs and ageing cast iron or lead plumbing. Poor ventilation in converted layouts traps moisture from daily living, encouraging black mould on cold external walls and within built-in cupboards. Shared pipe chases also mean slow leaks from neighbouring flats can remain hidden for months before becoming visible.
What our customers say
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.
