Leak to dry to treated, one company in South Kensington

South Kensington's housing stock is dominated by grand stucco-fronted Victorian terraces and red-brick mansion blocks, many long since divided into flats above basement or lower-ground conversions. This density of shared pipework, ageing risers and converted lower floors means a single failed joint or perished seal can send water travelling through several storeys before anyone notices.

Common leaks in South Kensington homes

Lower-ground and basement conversions

Many Victorian terraces near Cromwell Road and Onslow Square have had their lower-ground floors converted into extra bedrooms, kitchens or media rooms. Where tanking or waterproof membranes have failed, or a soil pipe joint has perished behind cladding, water tracks along floor voids and appears well away from its source, often soaking into skirting and flooring before staining becomes visible.

Flat and mansard roof extensions

Rear extensions and mansard additions to the borough's terraced houses frequently carry flat or near-flat felt or asphalt roofs. In older properties around Brompton and Gloucester Road these coverings degrade, crack or lift at the joints, letting rainwater seep into the loft void and travel along joists, so damage can surface in a bedroom ceiling one or two rooms from the actual leak.

Mansion block plumbing between flats

The mansion blocks around Queen's Gate and Thurloe Square rely on original or ageing shared risers and cast iron waste stacks serving several bathrooms stacked vertically. A perished washer or hairline crack in one flat's pipework can leak steadily through the floor slab into the ceiling of the flat below, causing disputes over responsibility and damage that is only found once plaster is opened up.

★★★★★

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.

Tip: If your water meter ticks over with every tap off, or a wall or ceiling stays damp with no obvious cause, there is a hidden leak. Finding it early is far cheaper than repairing the mould and damage it leaves behind.
