Leak to dry to treated, one company in Sevenoaks

Sevenoaks combines dense Victorian and Edwardian terraces around the High Street and station, 1930s semis on the town's outer roads, and older cottages and converted farmhouses in surrounding villages such as Ide Hill and Sundridge. This mix of ageing roofs, rear-return extensions and long-buried rural pipework means hidden leaks often develop quietly before anyone notices damage.

Areas of Sevenoaks we cover

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

Common leaks in Sevenoaks homes

Flat roof leaks on Victorian rear extensions

Many terraced and townhouses near Sevenoaks town centre have Victorian or Edwardian rear additions topped with old felt or lead flat roofs above kitchens and bathrooms. Once the covering perishes or flashing pulls away from the original brickwork, rainwater tracks along joists and drips into rooms below, often staining ceilings well away from the actual entry point and making the source hard to trace.

Perished shower seals in 1930s semis

The 1930s and post-war semis common across Sevenoaks Weald, Dunton Green and Riverhead were rarely built with tanked bathrooms. As original shower trays, tile grout and silicone seals age and crack, water escapes gradually through the floor into the room below, soaking joists and plasterboard for months before a ceiling stain finally reveals the ongoing leak.

Hidden pipework failures in loft and rear extensions

Strong demand for space in Sevenoaks's school catchment areas has driven many loft conversions and kitchen extensions, each adding new pipe runs boxed into ceilings and stud walls. A poorly soldered joint or a fitting that was never fully tightened can leak steadily behind plasterboard, and because the pipework sits out of sight, the escape of water often only surfaces once timber has swollen or a ceiling has bowed.

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.
