Leak to dry to treated, one company in Keston

Keston's housing stock ranges from characterful weatherboarded cottages near the pond and common to substantial 1930s detached houses and larger executive properties set back on wooded plots towards Leaves Green and Holwood. Many have older lead or copper plumbing, flat-roofed garages and extensions, and converted lofts or outbuildings, all of which create hidden points where water can escape unnoticed for weeks.

Areas of Keston we cover

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

Common leaks in Keston homes

Flat roofs on garages and rear extensions

Detached homes around Keston Mark and Leaves Green often have flat-roofed garages, utility rooms or kitchen extensions bolted onto the original house. Felt coverings and lead flashing around these joins perish over time, letting rainwater track along joists and down into ceilings and internal walls well away from the actual defect, so the leak is often blamed on the wrong room entirely.

Ageing pipework beneath period floors

The older cottages and farmhouses scattered around Downe and Single Street frequently retain original lead or galvanised pipework, now hidden beneath timber floorboards or solid screed added during later renovations. Corrosion and pinhole leaks in these pipes can run for a long time under flooring, leaving damp patches, musty smells or lifting boards as the only visible clue.

First-floor and loft en-suites leaking downward

Larger executive houses near Coney Hall and West Wickham have often gained additional en-suite bathrooms in loft conversions or first-floor extensions. Shower trays, tanking membranes and pipe seals in these newer bathrooms can fail quietly, sending water through the floor void into the ceiling and walls of the room below, sometimes only spotted once staining or a soft ceiling appears.

★★★★★

Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.

★★★★★

Very professional and organised I must say came out and completed the work very efficiently customer service was excellent. Definitely recommend this damp and mould service to anyone looking for a job done correctly. :)

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.
