Leak to dry to treated, one company in New Southgate

New Southgate's housing stock is a mix of Victorian and Edwardian terraces around the station, 1930s semi-detached homes further out, and postwar and more recent flat conversions near the North Circular corridor. Many properties have had loft, bathroom or rear extensions added over the decades, creating extra flat roofs, additional plumbing runs and ageing joints that are common sources of hidden leaks.

Common leaks in New Southgate homes

Flat roof extensions over kitchens and bathrooms

Many New Southgate terraces and semis have had single-storey rear extensions added, often topped with a flat roof beneath an upstairs bathroom or en-suite. Felt or GRP coverings degrade with age and perished flashing around upstands lets rainwater track inward, soaking joists and ceilings below long before a visible stain appears, particularly where extensions were built decades ago without modern waterproofing details.

Upstairs bathrooms leaking into ground floor rooms

The Edwardian and 1930s houses common in New Southgate typically have a single upstairs bathroom positioned directly above the kitchen or lounge. Failed shower seals, cracked tile grout or a slow leak from a bath overflow pipe can seep through floorboards unnoticed for months, eventually appearing as damp patches or sagging plaster ceilings in the room below, by which time the timber structure may already be affected.

Hidden pipework failures in converted flats

New Southgate has a good number of Victorian and Edwardian houses split into flats, plus newer conversions near the station and North Circular. Shared plumbing risers, boxed-in pipework and stacked bathrooms mean a failed joint or perished washer on one floor can silently escape into the flat below, soaking party walls and floors while remaining concealed behind boxing until damage becomes extensive.

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.
