Leak to dry to treated, one company in Southwark

Southwark's housing spans converted Victorian terraces in Camberwell and Peckham, Bermondsey and Rotherhithe warehouse conversions, post-war council estates, and new-build riverside blocks around Bankside and London Bridge. This mix of ageing pipework, subdivided flats stacked above one another, and flat-roofed extensions creates repeated opportunities for hidden escapes of water to develop unnoticed.

Areas of Southwark we cover

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

Common leaks in Southwark homes

Warehouse and loft conversions with shared pipework

Bermondsey and Rotherhithe's converted riverside warehouses often split single buildings into multiple flats sharing original soil stacks and water pipes. When joints in these older runs fail, water can travel through floor voids and exposed brickwork for some distance before it surfaces, leaving the flat below with staining long after the original leak began.

Flat roofs on estates and rear extensions

Many post-war estates and Victorian terrace extensions across Walworth, Camberwell and Peckham rely on flat roofs with felt or asphalt coverings. Once these perish or blister, rainwater tracks along joists rather than dripping straight through, so damp patches on ceilings often appear well away from the actual failure point, delaying repair.

Subdivided bathrooms leaking between flats

Terraced houses converted into flats near Peckham and East Dulwich frequently have bathrooms stacked directly above living rooms with only a single floor void separating them. Perished shower seals, cracked grout or an ageing waste trap can send water seeping into the ceiling below, causing plasterboard to bow before residents realise there is a problem.

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.
