Leak to dry to treated, one company in Herne Hill

Herne Hill's housing stock is dominated by tall Victorian and Edwardian terraces and semi-detached villas, many split into flats, alongside grander properties bordering Brockwell Park and a scattering of 1930s mansion blocks. This mix of ageing roofs, converted plumbing risers and stacked bathrooms means hidden leaks travel easily between floors, often surfacing well away from their true source.

Areas of Herne Hill we cover

We attend leaks right across Herne Hill and its neighbourhoods, including:

Common leaks in Herne Hill homes

Converted terraces with stacked bathrooms

Many Herne Hill terraces near Half Moon Lane and Poets' Corner have been divided into flats, with bathrooms plumbed directly above kitchens or living rooms in neighbouring units. A perished seal around a bath or shower tray can send water seeping through floor joists and ceiling voids for weeks, staining a downstairs neighbour's ceiling long before the upstairs occupant notices anything wrong.

Flat-roofed rear extensions

Victorian houses across Herne Hill Village and Brockwell Park's fringes commonly have flat-roofed rear additions covering kitchens or utility rooms. Ageing felt or asphalt coverings and worn flashing around parapets let rainwater track slowly through the roof deck and insulation, appearing as damp patches or bulging plaster well inside the room rather than directly beneath the actual point of entry.

Failed plumbing in period conversions

Older Edwardian and Victorian properties around Denmark Hill and Loughborough Junction often retain original lead or early copper pipework, sometimes hidden beneath later floorboards and skirting during conversion works. Joints weakened by age or disturbed during renovation can develop slow escapes of water within voids, soaking timber subfloors unnoticed until skirting boards swell or a musty smell develops.

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.

Great experience with this company from start to finish. They were professional, knowledgeable, and explained everything clearly without any pressure. The work was carried out efficiently and to a high standard, and we’ve already noticed a big improvement. It’s reassuring to deal with a team that genuinely cares about doing the job properly. Highly recommend to anyone dealing with damp or mould issues.

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.
