Leak to dry to treated, one company in Highgate

Highgate's housing ranges from Georgian townhouses and Victorian villas around the Village conservation area to Edwardian terraces and 1930s semis on the surrounding hills, many since converted into flats. This mix of older brickwork, ageing lead and cast iron pipework, flat-roofed rear extensions and multiple internal bathrooms stacked above one another creates numerous hidden points where water can escape unnoticed for weeks.

Common leaks in Highgate homes

Converted villas with stacked bathrooms

Many of Highgate's large Victorian and Georgian villas were split into flats decades ago, often with a bathroom fitted directly above the one below. Waste pipes and shower trays installed during these conversions were rarely designed for such loads, and perished seals or hairline pipe joint failures can send water tracking through floor voids into the flat beneath before anyone notices a problem.

Flat roofs on rear extensions

Rear kitchen and bathroom extensions added to Highgate's period terraces frequently have flat felt or asphalt roofs that were never intended to last as long as they have. As the membrane ages and cracks, rainwater seeps through slowly rather than pouring in, tracking along joists and appearing as damp patches or stained ceilings well away from the actual point of entry.

Ageing supply pipework in older brickwork

Properties around Highgate Village and North Hill often still contain original or early replacement copper and lead supply pipes buried within solid Victorian and Georgian brick walls. Corrosion or a failed joint in these concealed runs can release water gradually into masonry, leaving little external sign until plaster begins to bulge or a persistent damp smell develops.

What our customers say

Excellent
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.
