Leak to dry to treated, one company in Longfield

Longfield's housing runs from 1930s semis and cottages around Longfield Hill to the planned estates of New Barn built through the 1980s and 90s, alongside older rural properties towards Fawkham and Southfleet. This mix of ageing pipework, retrofitted en-suites and ambitious extensions means hidden leaks often develop unseen behind plaster, under floors or beneath flat roofs.

Common leaks in Longfield homes

En-suite leaks in New Barn's estate homes

Many New Barn houses were built with upstairs en-suite bathrooms positioned directly above living rooms and kitchens. When shower trays crack or waste pipe joints fail, water tracks silently through the floor void before staining a ceiling below. By the time discolouration appears, insulation and joists may already be saturated, so tracing the source early prevents far costlier repairs.

Ageing plumbing in Longfield Hill's older semis

The 1930s semis and cottages around Longfield Hill often retain original or partially updated soil stacks and copper pipework hidden within solid walls and suspended floors. Perished joint seals and corroded fittings can leak for weeks without visible signs, gradually rotting floor timbers and skirting. These properties benefit from moisture checks in accessible risers and under-stair cupboards where old plumbing runs are concentrated.

Flat roof failures on rural extensions near Fawkham and Southfleet

Detached and semi-rural homes towards Fawkham and Southfleet frequently have flat-roofed kitchen extensions, garages or utility rooms. Felt and rubber coverings degrade with age, and perished flashing seals around chimneys or parapets let rainwater seep into the roof void. Because these spaces are often unheated and rarely inspected, escape of water can travel along joists and emerge well away from the original point of entry.

What our customers say

★★★★★

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.

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.
