Leak to dry to treated, one company in Chiswick

Chiswick's housing stock ranges from Bedford Park's Arts and Crafts terraces and Victorian and Edwardian bay-fronted houses to interwar mansion blocks near Grove Park and riverside flat conversions along Strand-on-the-Green. Many terraces have been split into flats with shared plumbing stacks, while rear extensions and loft conversions add flat roofs and additional bathrooms, all increasing the potential for hidden leaks.

Areas of Chiswick we cover

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

Common leaks in Chiswick homes

Converted terrace flats with shared plumbing

Many Victorian and Edwardian houses around Turnham Green and Acton Green were divided into flats decades ago, leaving shared soil stacks and waste pipes boxed into walls and floors. A perished joint or cracked pipe on an upper floor can leak steadily behind plaster, showing up as a stain on a ground-floor ceiling long after the original damage began, often disputed between leaseholders over responsibility.

Flat roof rear extensions and loft conversions

Kitchen extensions and loft conversions are common across Chiswick's terraced streets, and many rely on felt or GRP flat roofs with limited falls and ageing upstands. Once the membrane perishes or flashing pulls away from an adjoining wall, rainwater tracks along joists and down internal walls, often surfacing well away from the actual defect and making the leak source hard to identify without opening up ceilings.

Mansion block and riverside flat plumbing failures

Interwar mansion blocks near Grove Park and riverside conversions along Strand-on-the-Green concentrate bathrooms and kitchens above one another, sharing risers between flats. A failed shower tray seal, split supply pipe, or overflowing appliance on an upper floor causes escape of water that spreads through communal floor voids, frequently affecting a neighbouring flat below before anyone in the source property notices a problem.

What our customers say

★★★★★

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.
