Leak to dry to treated, one company in Waterloo

Waterloo's housing stock ranges from Victorian terraces and mansion blocks split into flats, to 1960s and 1970s council estates with flat roofs, alongside newer riverside developments near the South Bank. This mix of converted period plumbing, ageing flat-roof coverings and densely stacked flats means hidden leaks travel quickly between neighbouring properties and floors below.

Areas of Waterloo we cover

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

Common leaks in Waterloo homes

Converted Victorian terraces with shared risers

Many Waterloo terraces near Lower Marsh and The Cut were split into flats decades ago, often sharing old plumbing risers boxed behind plasterboard. When a joint or pipe run fails inside these risers, water tracks down through floor voids and ceiling joists, appearing in a flat well below the actual source and delaying accurate diagnosis.

Flat-roofed estates and ex-council blocks

Areas around Kennington and Vauxhall include 1960s and 1970s flat-roofed blocks where felt or asphalt coverings have perished with age. Rainwater can sit and slowly penetrate through cracked upstands and worn flashings, tracking along ceiling voids before staining appears, often long after the covering itself first failed.

Failed bathroom seals in stacked flats

Waterloo's high proportion of subdivided and purpose-built flats means bathrooms are frequently stacked directly above living space. Perished silicone seals around shower trays, baths and waste pipes let water escape slowly through the floor structure, damaging the ceiling and possessions of the flat below before residents notice anything is wrong.

Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.

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.
