Leak to dry to treated, one company in Willesden Green

Willesden Green's housing stock is dominated by Edwardian and late-Victorian terraces, many long since converted into upper and lower flats, alongside red-brick mansion blocks near the Green and inter-war semis further out. Shared freeholds, ageing lead and cast-iron plumbing runs, and flat conversions with bathrooms stacked above neighbours' ceilings make hidden escapes of water a persistent, costly risk.

Common leaks in Willesden Green homes

Converted terraces with bathrooms over living rooms

Many Willesden Green terraces were split into flats decades ago, with a bathroom or en-suite fitted directly above a ground-floor lounge or kitchen. Perished shower trays, failed silicone seals and cracked grout let water track slowly through floor joists, appearing as staining or a sagging ceiling in the flat below long before anyone upstairs notices a problem.

Mansion block plumbing stacks

The mansion blocks around Willesden Green and Mapesbury share communal risers and old soil stacks serving multiple flats. A corroded joint or failed seal several floors up can send water tracking sideways through concrete floor slabs and party walls, surfacing in a neighbour's flat far from the original leak and complicating who is responsible for the repair.

Flat roofs on rear extensions and 1930s additions

Rear kitchen extensions and flat-roofed additions, common on Willesden Green's Victorian and 1930s properties, rely on felt or asphalt coverings that degrade with age and weather. Once the membrane splits or flashing pulls away from the main roof, rainwater seeps into ceiling voids unnoticed, causing timber decay and damp patches that only become obvious once the damage is well established.

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.
