Leak to dry to treated, one company in Crawley

Crawley's housing stock reflects its history as a post-war New Town, with 1950s-60s council-built terraces and maisonettes in Northgate and Three Bridges sitting alongside 1970s-80s estates such as Bewbush and Broadfield, plus later infill at Maidenbower. This mix of flat-roofed extensions, stacked flats and ageing original plumbing means hidden leaks surface in varied and often hard-to-trace ways.

Areas of Crawley we cover

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

Common leaks in Crawley homes

Flat roof extensions on New Town terraces

Many Crawley properties in Northgate, Southgate and Three Bridges gained kitchen or bathroom extensions during the 1960s and 1970s, often finished with flat roofs. These felt or asphalt coverings degrade with age, and water can track along joists for months before staining appears on a ceiling below, by which point insulation and timbers may already be saturated.

Maisonettes and flats with bathrooms above living space

Estates such as Bewbush, Broadfield and Gossops Green include stacked maisonettes and low-rise flats where a bathroom sits directly above a neighbour's lounge or kitchen. A cracked shower tray, failed grout or a slow leak from waste pipework can seep through the floor structure unnoticed, causing damage to the property below well before the occupant upstairs is aware of a problem.

Perished seals and ageing plumbing in original 1950s-60s stock

A good deal of Crawley's earliest New Town housing around Ifield, Langley Green and West Green still carries original or early-replacement plumbing runs. Rubber washers, tank seals and soldered joints perish over decades, and escape of water from an airing cupboard cylinder or hidden stopcock can run for a long period within voids before it becomes visible on skirting or flooring.

Rated 5.0 / 5 based on 21 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.
