Leak to dry to treated, one company in Knightsbridge

Knightsbridge's housing stock is dominated by stucco-fronted Victorian and Georgian townhouses split into flats, alongside Edwardian mansion blocks and high-value basement conversions near Harrods and Hyde Park. This mix of period plumbing risers, flat roofs and heavily serviced luxury bathrooms means hidden leaks often travel through shared structures before becoming visible, affecting several flats at once.

Areas of Knightsbridge we cover

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

Common leaks in Knightsbridge homes

Converted townhouse plumbing risers

Many Knightsbridge townhouses were divided into flats decades ago, leaving original pipework buried behind cornicing and plaster mouldings shared between floors. A failed joint or perished seal on an upper-floor riser can leak for weeks unseen, tracking down through party walls and ceilings before staining appears in a neighbouring flat below, by which time timber and plaster damage is often extensive.

Mansion block flat roofs and parapets

The area's Edwardian and early twentieth-century mansion blocks, common around Sloane Street and Basil Street, typically have flat or low-pitch roofs with lead flashing and parapet gutters. Once membranes age or flashing lifts, rainwater can penetrate silently and travel across joists, appearing as damp patches several rooms away from the actual entry point, complicating any repair.

Luxury basement and en-suite waterproofing

Knightsbridge's high-value basement conversions and multiple en-suite bathrooms rely on tanking membranes, underfloor heating pipework and shower waste connections that must perform faultlessly. Where tanking fails or a heating pipe develops a slow escape of water, moisture can sit within the floor buildup for a long period, causing hidden rot and mould before any visible sign reaches the surface.

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.

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.
