Leak to dry to treated, one company in Greenford

Greenford's housing stock is dominated by 1930s semi-detached and terraced homes built as the Central Line and Western Avenue opened the area to suburban expansion, alongside postwar council estates and low-rise flats around Greenford Green and Oldfield Lane. Many properties have had loft conversions, rear extensions and replacement bathrooms added over decades, disturbing original plumbing and roofing details that now quietly fail.

Common leaks in Greenford homes

Flat-roof extensions and failed felt coverings

Rear kitchen and bathroom extensions built onto Greenford's interwar semis very often carry flat roofs finished in felt or older asphalt. These coverings degrade, blister and split with age and weather cycling, letting water track slowly into the ceiling void below. Because the extension roof sits below sightline from the garden, perished felt often goes unnoticed until staining or a sagging ceiling appears inside.

Upstairs bathrooms leaking into rooms below

Many Greenford semis and terraces have had a second bathroom fitted above the kitchen or hallway during a loft or rear extension project. Perished shower tray seals, cracked grout around baths, or a failed waste pipe joint under the floor can send water into the ceiling void for weeks before a stain shows downstairs, often causing plaster and joist damage by the time it is found.

Ageing plumbing in postwar flats and estates

The postwar council-built flats and maisonettes around Greenford Green and Oldfield Lane still rely on original or early-replacement pipework in many cases. Corroded joints, perished rubber washers and hidden risers behind boxing-in are prone to slow escapes of water that spread between neighbouring flats through shared floors and walls before residents notice any visible sign.

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.
