Leak to dry to treated, one company in Catford

Catford's housing stock ranges from Victorian and Edwardian terraces around Rushey Green and Hither Green to 1930s semis, post-war council blocks and the prefabricated bungalows of the Excalibur Estate. This mix of old lead plumbing, flat-roofed rear extensions, converted flats and ageing high-rise pipework means hidden leaks develop differently street by street, often unnoticed until damage reaches a neighbouring property.

Common leaks in Catford homes

Flat roof extensions on Victorian terraces

Many Catford terraces near Rushey Green and Sandhurst Road have had rear kitchen or bathroom extensions added with flat felt or GRP roofs. These coverings degrade with age and weather cycling, allowing water to track slowly along joists into ceilings below. Because the damage often shows first as a small stain, it's frequently mistaken for condensation rather than a genuine escape of water requiring urgent repair.

Converted flats and stacked bathrooms

Larger Edwardian houses split into flats around Ladywell and Crofton Park often have bathrooms stacked directly above one another with shared soil stacks. Perished seals around baths, showers or waste pipes let water seep through floorboards into the flat below, causing damp patches on ceilings and cornicing that residents may not connect to their upstairs neighbour's plumbing.

Ageing pipework in post-war estates

Council-built blocks and estates such as those near Bellingham and the Excalibur prefabs rely on plumbing and heating systems installed decades ago. Failed joints, corroded pipe runs and worn valves behind boxed-in panels can leak for weeks before appearing as damp on walls or floors, by which point insulation, plasterboard and flooring have often already absorbed significant moisture.

★★★★★

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.
