Leak to dry to treated, one company in New Cross

New Cross is dominated by Victorian and Edwardian terraces converted into flats, alongside ex-council blocks around Hatcham and New Cross Gate and denser student accommodation serving Goldsmiths. This mix of subdivided period houses, flat-roofed extensions and ageing high-rise plumbing stacks means shared pipework, old bathroom conversions and roof coverings are frequently the source of hidden escapes of water between neighbouring flats.

Common leaks in New Cross homes

Converted terraces with stacked bathrooms

Many New Cross terraces were split into flats decades ago, often placing one bathroom directly above another using shared soil stacks and shallow floor voids. Seals around baths and shower trays perish over time, and grouting fails quietly, letting water track along joists into the ceiling below. Residents frequently notice a stain or damp patch long after the leak began.

Flat roof extensions to Victorian rears

Rear additions on New Cross's terraced housing commonly carry flat roofs installed as later extensions, often felt or asphalt coverings well past their intended lifespan. Once the membrane splits or pools with standing water, moisture seeps slowly into the ceiling void beneath the kitchen or bathroom extension, sometimes tracking sideways before any mark appears indoors, delaying detection considerably.

Ageing plumbing in converted and ex-council blocks

Blocks of flats around New Cross Gate and Hatcham rely on communal risers and older copper or lead pipework installed mid-century. Joints and fittings buried behind kitchen units or bathroom panels corrode and fail gradually, releasing water into neighbouring flats below. Because the pipework is hidden within boxed-in ducts, escapes often continue unnoticed until ceilings or walls in the flat downstairs show damage.

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.

Was lovely working with the team and they did a fantastic and quick job to get all the mould out of my bathroom. Very much looking forward to working with them on other projects around my house!! Thank you for everything and shout out to Karim for being so sweet!

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.
