Leak to dry to treated, one company in Dulwich

Dulwich's housing ranges from grand Georgian and Victorian villas around Dulwich Village and College Road to dense Victorian terraces in East Dulwich and mansion flats near Herne Hill and Tulse Hill. Many properties fall under Dulwich Estate covenants restricting alterations, so ageing plumbing, original roof coverings and old bathroom seals are often left in place well beyond their working life, quietly failing behind period fabric.

Areas of Dulwich we cover

We attend leaks right across Dulwich and its neighbourhoods, including:

Common leaks in Dulwich homes

Flat roof extensions over kitchens and side returns

East Dulwich and West Dulwich terraces have widely added flat-roofed rear kitchen and side-return extensions to gain space. Felt and old asphalt coverings on these low-pitch roofs perish or blister within a couple of decades, letting rainwater track along joists and down into plasterboard ceilings below. Because the leak point on the roof rarely sits above the stain inside, damage is frequently misdiagnosed and left running for months.

Converted mansion flats with bathrooms stacked above neighbours

Herne Hill, Tulse Hill and North Dulwich have many large Victorian houses split into flats, with bathrooms and en suites added directly above another owner's rooms. Failed shower trays, cracked tile grout and perished silicone seals around baths let water seep through original lath and plaster or timber floors into the flat below, often only discovered once a ceiling bulges or a downstairs neighbour reports staining.

Ageing supply pipework in unaltered period houses

Dulwich Village and College Road properties, protected by estate covenants, often retain original or early-replacement lead, copper and cast iron pipework hidden under floorboards and within thick solid walls. Joints corrode and soldered fittings weaken quietly over years, and because access is restricted by conservation rules, escapes of water can run for long periods within voids before damp patches or dropping water pressure reveal the fault.

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.
