Leak to dry to treated, one company in Greenwich

Greenwich mixes Georgian and Victorian terraces around Crooms Hill and the town centre, 1930s semis in Eltham and Kidbrooke, converted period houses in Blackheath and Westcombe Park, and riverside new-build flats on Greenwich Peninsula. This range of ages and constructions means old lead pipework, flat roof extensions, converted bathrooms and modern balconies all fail in different ways, often silently.

Common leaks in Greenwich homes

Old plumbing under Greenwich's period terraces

Many Georgian and Victorian terraces near Crooms Hill and the town centre still run on ageing lead, copper or early plastic pipework hidden beneath timber floorboards. Joints corrode and perish gradually rather than bursting outright, so water tracks along joists and skirting for weeks before staining appears on a ceiling below, often at the opposite end of the room from the actual source.

Flat roofs and balconies on Peninsula developments

The newer riverside flats around Greenwich Peninsula and East Greenwich frequently feature flat roofs, recessed balconies and roof terraces sealed with membranes and flashing. Once these perish or are punctured, rainwater tracks sideways under the felt or membrane rather than dripping straight through, so it can travel several metres before it shows as a damp patch on a wall or ceiling in a flat below.

Converted bathrooms leaking through Blackheath and Westcombe Park houses

Large Victorian and Edwardian houses in Blackheath and Westcombe Park were commonly split into flats, with bathrooms stacked above kitchens or added over rooms never designed to be wet areas. Perished shower tray seals, cracked grout and ageing waste pipes let water seep into original floor timbers, and because pipework is often shared between converted units, tracing which flat is actually responsible for the escape of water can be difficult.

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.
