Leak to dry to treated, one company in New Barnet

New Barnet's housing stock is a mix of Victorian and Edwardian terraces built up around the railway station, interwar semi-detached houses on the surrounding roads, and a growing number of flat conversions and small blocks near the town centre. This blend of old pipework, added bathrooms, flat-roofed extensions and shared plumbing between converted flats creates many opportunities for hidden leaks to develop unnoticed.

Common leaks in New Barnet homes

Victorian terraces with bathrooms over kitchens

Many of New Barnet's Victorian and Edwardian terraces, particularly around the station and Station Road, had bathrooms retrofitted directly above kitchens. Old lead or early copper pipework and joint seals in these properties are now well past their intended lifespan. A slow failure at a joint or waste pipe can soak into floor joists and ceiling plaster for weeks before a stain or sagging ceiling gives it away below.

Flat roofs on 1930s semi extensions

The interwar semi-detached houses common on New Barnet's residential roads are frequently extended at the rear with flat-roofed kitchens, utility rooms or dormer loft conversions. Felt and older bitumen coverings on these roofs perish with age and UV exposure, splitting quietly at joints and upstands. Water then tracks along roof timbers before appearing as damp patches well away from the original point of entry.

Escape of water in converted flats

A number of larger Victorian and Edwardian houses in New Barnet have been divided into flats, meaning plumbing stacks, shower trays and washing machine connections are shared between floors owned by different leaseholders. A perished shower seal or failed appliance hose upstairs can send water through floor voids into the flat below, often going unnoticed until a ceiling stain or dispute over responsibility for the escape emerges.

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.
