Leak to dry to treated, one company in Wandsworth

Wandsworth's housing stock ranges from Victorian and Edwardian terraces split into flats, through 1930s mansion blocks in Putney and Wandsworth Town, to riverside apartment towers near Nine Elms and Battersea. This mix of ageing shared pipework, flat-roofed rear extensions and stacked bathrooms in converted properties means a failed joint or perished seal often travels between neighbouring flats.

Areas of Wandsworth we cover

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

Common leaks in Wandsworth homes

Flat-roofed rear extensions and perished seals

Many Victorian and Edwardian terraces across Balham, Tooting and Earlsfield have been extended at the rear with flat roofs to create larger kitchens or bathrooms. These roofs rely on felt or GRP membranes and roof-light seals that perish over time, allowing water to track along joists and ceiling timbers unnoticed for months before staining appears on the kitchen ceiling below.

Stacked bathrooms in converted mansion blocks and flats

Wandsworth Town, Putney and Southfields contain many Victorian houses and 1930s mansion blocks split into multiple flats, often with bathrooms stacked directly above one another. Shared waste pipes, shower trays and silicone seals around baths can fail quietly, sending water through the floor void into the ceiling of the flat below, a common source of dispute between leaseholders.

Concealed pipework in riverside new-builds and podium decks

Newer developments around Nine Elms, Battersea and the riverside near Wandsworth Bridge feature concealed pipework, underfloor heating manifolds and podium-deck waterproofing above basement parking and communal amenities. When a joint fails or a podium membrane degrades, water can travel a long way from its source before it surfaces, making these escapes harder to trace and often more costly to repair.

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.
