Leak to dry to treated, one company in Charlwood
Charlwood's housing mix runs from timber-framed and weatherboarded cottages around the historic village core to brick farmhouses, barn conversions and post-war infill on its fringes. Many older properties have solid walls, low ceilings and small original windows, while barn conversions often retain exposed roof structures with limited ventilation, together creating conditions where moisture struggles to escape and mould readily takes hold.

Common causes of mould in Charlwood homes
Solid-wall cottages and penetrating damp
Charlwood's older weatherboarded and brick cottages generally have solid walls rather than a cavity, so rainwater and ground moisture can pass straight through the fabric. This penetrating damp shows up as mould on external walls, particularly north-facing rooms and behind wardrobes or beds pushed against cold surfaces, where trapped air prevents the wall from drying out between wet spells.
Barn and outbuilding conversions
A number of Charlwood homes are converted barns or agricultural outbuildings, often with vaulted ceilings, exposed timber and limited or poorly ducted extraction in bathrooms and kitchens. Moisture from cooking, bathing and breathing has nowhere efficient to go, settling instead on cold roof slopes, around rooflights and in bedrooms, where mould spreads across plaster and timber before residents notice a problem.
Retrofitted glazing and reduced ventilation
Many Charlwood properties near Gatwick's flight paths have had double glazing and additional insulation fitted for noise reduction, sealing homes far more tightly than they were originally built for. Without matching upgrades to ventilation, humid air becomes trapped indoors, leading to condensation and black mould around window reveals, in bathrooms and bedrooms, and behind furniture set against exterior walls.

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.
