Leak to dry to treated, one company in Hanworth

Hanworth's housing stock is dominated by mid-century local authority estates built around the former RAF Hanworth Park airfield, alongside 1930s and post-war semis and low-rise maisonette blocks. Many properties retain original flat-roofed extensions, single-glazed bathrooms and ageing lead or copper plumbing runs, all of which age poorly and quietly let water into ceilings, floors and party walls between neighbouring homes.

Common leaks in Hanworth homes

Flat-roofed extensions and garages

A large share of Hanworth's semis and ex-council terraces were extended in the 1960s to 1980s with flat-roofed kitchens, bathrooms or garages. Felt and asphalt coverings on these roofs degrade with age and sun exposure, developing splits and pooling water that seeps through the deck unnoticed. Owners often only spot the damage once ceiling boards below have swollen or stained.

Upstairs bathrooms leaking into rooms below

Many Hanworth properties near Hanworth Park and the Air Park estates have had upstairs bathrooms retrofitted or refitted over the decades. Perished shower seals, cracked grout and failed waste pipe joints let water track along joists rather than showing straight away, so damage to the kitchen or lounge ceiling below can be well advanced before it is noticed.

Ageing plumbing in maisonette blocks

The low-rise maisonette and flat blocks common around Hanworth, including converted ex-local authority stock, often still run original copper or early plastic pipework behind boxed-in ducts. Corroded joints or perished washers cause slow escapes of water that spread between flats before residents realise, since the source is hidden inside a neighbouring property's fabric.

Rated 5.0 / 5 based on 20 reviews on
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.
