Leak to dry to treated, one company in Clerkenwell

Clerkenwell's housing stock is dominated by converted Victorian warehouses and former print works turned into loft apartments, sitting alongside Georgian terraces, mansion blocks and newer infill developments around Farringdon and St Luke's. These industrial conversions often carry retrofitted plumbing and flat roofs never designed for residential use, making hidden leaks a persistent risk.

Common leaks in Clerkenwell homes

Retrofitted Plumbing in Warehouse Conversions

Many Clerkenwell flats occupy former printworks, factories and clothing warehouses where plumbing stacks were added decades after the original build. Pipework often runs through boxed-in service ducts between floors, so a failed joint or corroded soil stack can leak for weeks unnoticed, tracking along structural beams before staining a ceiling several units away from the actual source.

Flat Roofs on Converted Industrial Buildings

The area's converted warehouses and light-industrial units frequently have flat or low-pitch roofs added during residential conversion, often with roof terraces above top-floor apartments. Ageing membranes, blocked outlets and poorly sealed upstands around rooflights let rainwater penetrate slowly, saturating insulation and timber joists long before any damp patch becomes visible inside the flat below.

Bathrooms Leaking Through Converted Floors

Clerkenwell's loft-style conversions often stack bathrooms above open-plan living areas separated only by timber floors retained from the original industrial build. Perished shower seals, cracked grout or a slow-leaking waste pipe can send water straight through exposed floorboards into the ceiling below, affecting exposed brickwork, timber beams and any electrics run through the same void.

★★★★★

I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.

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.
