Leak to dry to treated, one company in Cobham

Cobham's housing stock ranges from large detached executive homes and gated developments around Fairmile and Tartar Hill to older 1930s properties in Stoke D'Abernon and Downside. Many houses feature extensive plumbing for multiple en-suites, swimming pools and flat-roofed extensions, while the River Mole's proximity raises groundwater levels, all increasing the likelihood of hidden leaks going unnoticed.

Areas of Cobham we cover

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

Common leaks in Cobham homes

Flat roof extensions on executive homes

Many of Cobham's larger properties near Fairmile and Church Street have added flat-roofed garden rooms, orangeries and garage conversions. Perished felt or ageing GRP membranes on these extensions can let water track along joists for months before staining appears on ceilings below, particularly where the extension joins an older brick wall and flashing has degraded unnoticed.

En-suite bathrooms in multi-storey homes

Cobham's executive houses in Downside and Stoke D'Abernon often have several en-suite bathrooms stacked above living rooms and kitchens. Perished shower tray seals or grouting failures let water seep into the floor void, tracking along ceiling joists before it shows as a stain or bulge in the room below, by which point timber and plasterboard may already be affected.

Underfloor plumbing in period and converted properties

Older cottages and converted barns around Ockham and Hatchford frequently have concealed pipework beneath solid or suspended floors, sometimes updated during renovations without proper isolation valves. A failed joint or corroded fitting can leak steadily for weeks, softening floorboards or lifting parquet, with damp only becoming obvious once skirting boards or nearby walls begin to discolour.

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.
