Damp, mould & leak services in Harlow
Harlow is a post-war new town built predominantly from the late 1940s onwards, featuring a substantial stock of system-built and prefabricated properties, concrete panel houses, flat-roofed maisonettes and low-rise estates alongside older Victorian and Georgian cottages in Old Harlow and Churchgate Street. This varied mix creates a wide range of persistent damp, mould and leak vulnerabilities.

Common damp problems in Harlow homes
Concrete Panel and System-Built Construction
Much of Harlow's new town housing stock was erected using non-traditional construction methods including no-fines concrete and prefabricated panels. Over decades, joints between panels degrade, allowing rainwater to penetrate wall cavities. Residents in areas such as Netteswell and Mark Hall frequently report damp patches on internal walls that are misdiagnosed as condensation but originate from failing external panel junctions.
Flat Roof Failures on Maisonettes and Walkway Decks
Harlow's post-war masterplan incorporated a large number of maisonettes, deck-access blocks and communal walkways with flat or shallow-pitched roofs. In areas like Staple Tye and Great Parndon, ageing felt or asphalt roof coverings blister and crack, allowing water ingress directly into upper-floor ceilings and airing cupboards. These leaks are often slow and hidden behind plasterboard before becoming visible.
Rising and Penetrating Damp in Old Harlow Cottages
The historic core around Old Harlow, Potter Street and Churchgate Street contains solid-walled cottages and Victorian terraces with no cavity insulation and often inadequate or failed damp-proof courses. Rising damp tracking up ground-floor walls and penetrating damp driven through porous brickwork by driving rain are common findings, frequently accompanied by salt deposits, peeling plaster and persistent mould growth at skirting level.
