Leak to dry to treated, one company in Earlsfield

Earlsfield is dominated by rows of Victorian and Edwardian terraces, many split into flats, alongside ex-council blocks near Garratt Lane and newer developments beside the River Wandle. Original slate roofs, ageing lead flashings and multiple stacked bathrooms mean hidden escapes of water travel quickly between converted flats, often surfacing as damp patches or stained ceilings well away from the original source.

Common leaks in Earlsfield homes

Leaks between converted Victorian flats

Many Earlsfield terraces on streets around Magdalen Road and Burntwood Lane were split into upper and lower flats decades ago, with plumbing runs added above original ceilings. A failed joint or perished seal in an upstairs bathroom can travel along joists before showing as a stain in the flat below, making the true source hard to trace without proper leak detection.

Flat roof extensions and rear additions

Rear kitchen extensions and loft conversions are common across Earlsfield's terraced streets, and many rely on flat or low-pitch felt or GRP roofing. Perished membranes, cracked flashing around parapets, and poorly sealed rooflights allow water to enter gradually, often tracking along ceiling voids before any visible damp appears inside.

Ageing pipework in ex-council and riverside blocks

The low-rise council-built blocks near Swaffield Road and Ravensbury Terrace, along with older flats close to the Wandle, often still run original mid-century plumbing. Corroded joints and worn washers can fail slowly behind boxed-in pipework, leaking unnoticed into neighbouring flats below until flooring or plasterboard shows signs of prolonged saturation.

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.

I have been dealing with damp and mould for years but these guys were able to come in and resolve the problem quickly and professionally. Their prices were fair and reasonable and they got the job done clean. 10/10 would use again and would recommend.

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.
