Leak to dry to treated, one company in Chelsea
Chelsea's housing runs from Georgian and Victorian terraces around Cheyne Walk to red-brick mansion blocks near Sloane Square and riverside developments at Chelsea Harbour. Many terraces have been converted into flats or extended into basements and lower ground floors, while older buildings retain original lead pipework and flat-roofed rear additions, all of which age poorly and hide leaks well before damage surfaces.

Common leaks in Chelsea homes
Basement and lower ground floor conversions
Chelsea's Victorian terraces are frequently dug out or converted into basement bedrooms, kitchens and home cinemas, particularly around World's End and Little Chelsea. Tanking membranes and cavity drainage systems fitted during these conversions can fail at joints or pump connections, letting groundwater or leaking pipework above seep in slowly. Because these rooms are enclosed and below grade, damp often spreads through plasterboard and flooring for weeks before it is noticed.
Flat roofs on rear extensions and mews additions
Many Chelsea terraces and mews houses have flat-roofed kitchen extensions or loft additions with felt, asphalt or GRP coverings. Once perished or split, particularly around upstands and roof lights, rainwater tracks along joists before dripping through ceilings in rooms well away from the actual defect. Given Chelsea's dense terracing, these leaks frequently affect neighbouring party walls and shared structures, complicating both diagnosis and repair.
Ageing pipework in converted mansion blocks and stacked flats
Period mansion blocks around Sloane Square and South Kensington were subdivided into flats decades ago, often stacking bathrooms and kitchens above one another on original lead or cast iron pipework. Perished seals around baths, showers and waste connections let water travel between joists into the flat below, while shared risers in leasehold blocks make tracing the exact source, and agreeing responsibility for it, notably slow.

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.
