Leak to dry to treated, one company in Borough

Borough's housing mix ranges from Victorian terraces and ex-local authority blocks around Snowsfields and Long Lane to converted Victorian warehouses and modern riverside developments near Bankside. This blend of ageing brickwork, flat-roofed extensions and stacked flats above shops and offices means hidden water leaks often travel between old and new construction before anyone notices damp patches or falling ceilings.

Common leaks in Borough homes

Converted warehouse flats and failed plumbing joints

Many Borough properties near Bankside and London Bridge are Victorian warehouses converted into flats, with plumbing retrofitted into original brick and timber structures. Pipework often runs through boxed-in ducts or under floors that weren't designed for modern bathrooms and kitchens. When a joint fails or a pipe perishes, water tracks along old joists and brickwork, soaking neighbouring units before staining appears, making the source hard to trace without moisture mapping.

Flat roofs on ex-local authority and mansion blocks

Blocks around Walworth, Newington and Elephant and Castle frequently have flat or low-pitch roofs covering communal areas, extensions or top-floor flats. Felt or asphalt coverings degrade with age and weather exposure, and perished flashing around vents or parapets lets water seep in slowly. Because these roofs sit above multiple flats, a small leak can spread across several ceilings before residents below notice discolouration or sagging plaster.

Stacked bathrooms leaking through to flats below

In the mansion blocks and mixed-use buildings around Borough Market and Tower Bridge, bathrooms are often stacked directly above commercial units or other flats. Perished shower seals, cracked tanking behind tiles, or failed waste pipe connections allow water to escape gradually through floor voids. Occupants below may only spot the problem once a ceiling bulges or a light fitting dampens, by which point timber joists and insulation have often 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.
