Leak to dry to treated, one company in Soho

Soho's housing stock is dominated by narrow Georgian and Victorian terraces, many converted into flats stacked above restaurants, bars and shops, alongside mansion blocks and mixed-use conversions squeezed onto tight footprints. Shared risers, communal plumbing runs and party-wall bathrooms serving several flats mean a single failure can travel fast, while cramped rear extensions and flat-roofed additions common across the district add further points where water can get in unnoticed.

Common leaks in Soho homes

Failed plumbing in converted upper-floor flats

Many Soho buildings were carved into flats decades ago, with kitchens and bathrooms plumbed into risers never designed for the current number of units. Joints under sinks, old soil stacks and shared supply pipes running through party walls above restaurants or bars often fail quietly, sending water down through floor voids and ceiling timbers before staining appears on the commercial unit below.

Leaking flat roofs over rear extensions

The rear closet wings and single-storey extensions typical of Soho's terraced buildings are frequently topped with flat felt or asphalt roofs that were never built to last. Perished membranes, blocked outlets and standing water after heavy rain let moisture track along joists into the rooms below, often surfacing well away from the actual roof defect.

Bathrooms leaking through to the floor below

In Soho's stacked flats and flats-above-shops, upper-floor bathrooms often sit directly over living space or trading premises with only timber floorboards between them. Perished tray seals, cracked grout and worn shower enclosure seals let water seep into the floor structure over time, showing up as ceiling staining, warped flooring or damp smells in the unit beneath long before the leak itself is found.

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.
