Damp, mould & leak services in Thamesmead
Thamesmead is dominated by large-scale social housing estates built primarily from the 1960s through the 1980s, featuring concrete deck-access blocks, low-rise maisonettes and prefabricated system-built dwellings. This combination of aging concrete construction, flat roofing, elevated walkways and poor original insulation makes the area particularly susceptible to persistent damp, mould growth and water ingress.

Common damp problems in Thamesmead homes
Concrete Deck-Access Blocks and Penetrating Damp
Thamesmead's iconic deck-access concrete blocks were constructed using large-panel system building techniques that are now several decades old. Degraded concrete joints, failed sealants between panels and cracked parapet walls allow rainwater to penetrate deeply into external walls. Residents often report damp patches appearing on internal walls, particularly on upper floors, during prolonged wet weather, and these faults are frequently hidden behind internal plasterboard linings.
Flat Roofs and Ponding Water on Maisonettes
A significant proportion of Thamesmead's low-rise maisonettes and deck housing were built with flat or near-flat roofs that have limited falls for drainage. Over time, the original felt or asphalt coverings degrade, blister and split, allowing water to pond and eventually track through roof structures into upper-floor ceilings and bedroom walls. Identifying the precise entry point often requires specialist survey work rather than simple visual inspection.
Condensation Mould in Poorly Ventilated System-Built Homes
The system-built dwellings throughout Thamesmead were designed with minimal cavity insulation and few purpose-built ventilation provisions. Cold bridging at concrete wall junctions and around window reveals creates consistently cold internal surfaces where warm, moisture-laden air condenses readily. Bathrooms, kitchens and north-facing bedrooms are particularly affected, with black mould colonising corners, wardrobe interiors and window reveals that are difficult to treat without addressing the underlying thermal deficiency.
What our customers say
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.
