Leak to dry to treated, one company in Willesden

Willesden's housing stock is a mix of Victorian and Edwardian terraces split into flats, 1930s semis around Dollis Hill and Neasden, mansion blocks near Willesden Green, and post-war council estates. Many terraces have been converted with shared plumbing stacks and added bathrooms, while flat-roofed rear extensions are common, leaving ageing pipework and coverings prone to hidden leaks.

Common leaks in Willesden homes

Converted terraces with shared plumbing stacks

Many of Willesden's Victorian and Edwardian terraces were divided into flats decades ago, often with bathrooms added above kitchens or living rooms. Shared soil stacks and old branch pipework run through party floors and walls, so a failed joint or perished washer can leak for weeks unseen, tracking along joists before staining a ceiling in the flat below.

Flat roof extensions over kitchens and bathrooms

Rear additions with flat roofs are common across Willesden's terraced streets, typically covering kitchen extensions or bathrooms above. Felt or older asphalt coverings perish with age and sun exposure, and upstands and roof-to-wall joints are frequent failure points. Water can enter gradually through a small split, saturating insulation and timber long before a stain appears indoors.

Ageing bathrooms in mansion blocks and 1930s semis

Purpose-built mansion blocks around Willesden Green and the 1930s semis near Dollis Hill and Neasden often retain original or dated bathrooms. Silicone sealant around baths, showers and tiling degrades over time, allowing water to seep behind surfaces and through floor structures. In blocks of flats this frequently shows up as an escape of water affecting the ceiling of the flat below.

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.
