Leak to dry to treated, one company in Barnet

Barnet's housing ranges from Victorian and Edwardian terraces in New Barnet and Friern Barnet, through 1930s suburban semis in Whetstone and Mill Hill, to interwar mansion blocks in Hendon and larger detached homes in Totteridge and Arkley. This variety means old plumbing, flat roofs and converted bathrooms age differently, giving hidden leaks many different places to start.

Areas of Barnet we cover

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

Common leaks in Barnet homes

Flat roof extensions on 1930s semis

Many semi-detached houses in Whetstone, Mill Hill and Totteridge have had rear kitchen extensions or loft conversions added with flat roofs. Felt or older asphalt coverings perish and split with age, letting water track along joists before it appears as a ceiling stain. Because the damage travels sideways before dropping, the visible mark is often well away from the actual failure point.

Converted terraces with stacked bathrooms

Victorian and Edwardian terraces in New Barnet, Friern Barnet and North Finchley were widely split into flats during the twentieth century, often with a bathroom fitted directly above the flat below. Perished shower tray seals, cracked grout or a failed waste pipe joint can send water through the floor void for weeks before a tenant downstairs notices staining, since the leak sits hidden between floorboards and the ceiling.

Ageing pipework in mansion blocks and larger homes

Interwar mansion blocks in Hendon and Edgware, alongside larger detached houses in Totteridge and Arkley, often still run original or mid-century supply and waste pipework beneath solid or suspended floors. Corroded joints, perished washers and gradual pinhole failures release water slowly, and because these properties frequently have layered flooring or panelled ceilings, escape of water can spread unseen for a long time before a visible sign appears.

What our customers say

★★★★★

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.
