Leak to dry to treated, one company in Downham

Downham is largely a 1920s and 1930s LCC cottage estate of two-storey semi-detached and terraced houses, with pebbledash render, pitched tiled roofs and small rear outriggers. Many properties have had bathrooms extended above kitchens, flat-roofed garages added, or lofts converted, and these later alterations are where hidden leaks most often start.

Common leaks in Downham homes

Flat-roofed extensions and garages

Downham's terraced and semi-detached plots commonly have single-storey rear extensions or garages finished with felt or asphalt flat roofs. These coverings perish with age and UV exposure, splitting at joints and upstands. Water tracks along joists rather than dropping straight down, so damp patches on the extension ceiling can appear well away from the actual failure point, delaying discovery.

Bathrooms built over kitchen outriggers

Many Downham cottages have their bathroom positioned above a single-storey kitchen outrigger, a layout typical of this estate's original design. Failed pipe joints, cracked tile grout or a worn shower tray seal allow water to seep through the floor into the kitchen ceiling below, often soaking timber joists for weeks before staining, sagging plaster or a musty smell gives it away.

Perished seals around period windows and bays

The estate's characteristic bay windows and older steel-framed casements rely on flashing and mastic seals that harden and crack over the decades. Once perished, driving rain gets behind the render and window reveals, tracking down inside the cavity or party wall. This escape of water frequently surfaces as damp low on an internal wall, well below where the actual seal has failed.

★★★★★

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.
