Leak to dry to treated, one company in Gerrards Cross

Gerrards Cross is dominated by large detached properties, many built in the 1920s and 1930s alongside newer executive homes near the golf course and commons. These substantial houses typically have multiple bathrooms, en-suites, extensions and basements, meaning more pipework, more joints and more opportunity for a hidden leak to travel unseen through floors and ceilings before it is noticed.

Common leaks in Gerrards Cross homes

Multiple en-suites feeding leaks into rooms below

Many Gerrards Cross homes were extended to add en-suite bathrooms above kitchens, studies or reception rooms. A failed shower tray seal or cracked waste pipe can send water tracking along joists for weeks, appearing as a stain or bulge on the ceiling below long after the original leak began, by which point timber and plasterboard are already saturated.

Flat-roofed extensions and orangeries

The area's larger plots have encouraged flat-roofed garages, orangeries and side extensions, particularly on 1960s and 1970s additions to older houses. Felt or asphalt coverings degrade with age and UV exposure, allowing water to enter above the ceiling void and spread sideways before any damp patch becomes visible internally.

Ageing pipework and perished seals in period properties

Gerrards Cross's stock of interwar detached houses often retains original or older replacement plumbing runs beneath suspended timber floors. Perished washers, cracked soldered joints and degraded seals around baths and basins can leak slowly into subfloor voids, causing rot and mould that stays hidden until floorboards are lifted or a 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.
