Leak to dry to treated, one company in Crawley
Crawley's housing stock reflects its history as a post-war New Town, with 1950s and 60s council-built estates in Northgate, Langley Green and West Green sitting alongside older Ifield village cottages and newer 1980s-90s developments in Bewbush, Broadfield and Maidenbower. This mix of construction methods, insulation standards and ventilation provision means mould causes arise differently across the borough, from cold system-built walls to poorly ventilated modern flats.

Common causes of mould in Crawley homes
System-built New Town estates and cold bridging
Many Crawley properties in Northgate, Langley Green and West Green date from the town's original 1950s and 60s development, built with concrete panel or thin cavity walls and minimal insulation. These cold bridges attract condensation, and black mould readily forms around window reveals, in corners and along external walls in bedrooms, particularly through autumn and winter when heating patterns are inconsistent.
Flat roofs and maisonette leaks
Crawley has a high number of flat-roofed houses and low-rise maisonettes across estates such as Bewbush, Furnace Green and Gossops Green. Flat roof coverings and parapet details are prone to age-related failure, letting water penetrate ceilings and top-floor walls unnoticed for months. The resulting damp patches develop into persistent mould, often spreading into loft hatches and airing cupboards before residents identify the source.
Sealed modern homes and trapped moisture
Later estates including Maidenbower and Broadfield were built with tighter, double-glazed construction that reduces natural draughts. Without adequate trickle ventilation or extractor use, everyday moisture from cooking, bathing and drying laundry becomes trapped indoors, settling as condensation on bathroom walls, behind wardrobes and in bedroom corners where airflow is weakest, allowing mould to establish quickly.

I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.

Was lovely working with the team and they did a fantastic and quick job to get all the mould out of my bathroom. Very much looking forward to working with them on other projects around my house!! Thank you for everything and shout out to Karim for being so sweet!
