Leak to dry to treated, one company in Thamesmead

Thamesmead was built from the late 1960s as a new town of concrete system-built tower blocks, low-rise deck-access maisonettes and interlinked flats around its lakes, later supplemented by newer riverside developments. This legacy of flat-roofed concrete construction and stacked flats sharing walls and floors means hidden water leaks spread easily between properties and are often difficult to trace to their source.

Common leaks in Thamesmead homes

Flat roof failures on concrete blocks

Many of Thamesmead's original low-rise and tower blocks around Southmere and Tavy Bridge were built with flat felt or asphalt roofs now well past their intended lifespan. Once the covering splits or blisters, rainwater tracks along the concrete deck before dropping through ceilings, often appearing far from the actual breach and leaving top-floor flats with persistent damp patches and stained plasterboard.

Perished seals in system-built panels

The large panel system construction used across parts of Thamesmead relies on sealed joints between precast concrete panels. As the original mastic and gaskets age and perish, wind-driven rain and condensation find their way into the cavity, tracking downward through the structure. This hidden ingress can saturate insulation and internal linings long before any staining becomes visible indoors.

Bathroom leaks through stacked flats

With so much of the housing stock built as maisonettes and deck-access flats stacked one above another, a failed shower tray, cracked waste pipe or worn seal in an upstairs bathroom can send water straight through the floor into the ceiling of the flat below. Shared risers and boxed-in pipework in these buildings make locating the actual escape of water particularly difficult without specialist detection.

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.

★★★★★

Very professional and organised I must say came out and completed the work very efficiently customer service was excellent. Definitely recommend this damp and mould service to anyone looking for a job done correctly. :)

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.
