Leak to dry to treated, one company in Norwood

Norwood's housing stock spans large Victorian and Edwardian terraces in West Norwood and Crystal Palace, many converted into flats, alongside 1930s semis near South Norwood and postwar blocks around Selhurst. Subdivided period properties, ageing plumbing and bolted-on rear extensions mean hidden leaks often develop behind floorboards, under bathroom conversions or beneath old flat roofs.

Areas of Norwood we cover

We attend leaks right across Norwood and its neighbourhoods, including:

Common leaks in Norwood homes

Stacked bathrooms in converted terraces

Many Victorian terraces in West Norwood and Gipsy Hill were split into two or three flats decades ago, often with a bathroom stacked directly above the flat below's living space. Original floor joists and lath-and-plaster ceilings hide escaping water for weeks, so a slow leak from a shower tray or waste pipe can soak a downstairs ceiling before anyone upstairs notices.

Ageing flat roofs on rear extensions

Rear kitchen extensions with flat roofs are common on the Victorian and Edwardian terraces around Crystal Palace and Upper Norwood, and many now have felt or old asphalt coverings well past their intended lifespan. Perished flashing and cracked upstands let rainwater track slowly along joists into the extension below, causing damp patches and swollen plaster that only appear once the timber underneath has been saturated.

Hidden pipework under solid 1930s floors

South Norwood and Selhurst have a good number of 1930s semis with solid concrete ground floors, where copper or old lead supply pipes run beneath the slab. A pinhole failure or perished joint here cannot simply be seen, and water tracks sideways under the floor before surfacing as a damp patch or lifted skirting, often some distance from the actual source of the leak.

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.
