Leak to dry to treated, one company in Portslade
Portslade's housing runs from Victorian and Edwardian terraces around the old village and seafront to 1930s bay-fronted semis toward Mile Oak and Hangleton, with harbourside flats and converted houses near Fishersgate and Station Road. Solid brick walls, single glazing and older extensions combine with sea-facing exposure to driving rain, making condensation and penetrating damp persistent problems across the area.

Common causes of mould in Portslade homes
Victorian and Edwardian terraces near the old village and seafront
Many of Portslade's terraces have solid brick walls with no cavity, plus original sash windows that struggle to seal against salt-laden sea air. Rain gets driven into the brickwork and window reveals, while cold internal walls encourage condensation on plaster. This shows up as black mould around window frames, on chimney breasts, and creeping across bedroom walls that back onto unheated hallways.
1930s bay-fronted semis in Mile Oak and Hangleton
Inland estates built in the 1930s often have loft conversions or rear extensions added later, sometimes with flat roofs that trap moisture or poorly detailed junctions where old and new brickwork meet. Combined with cavity walls that were never properly insulated, this leads to damp patches and mould in upstairs bedrooms, around dormer windows, and behind wardrobes pushed against colder external walls.
Converted flats and shared housing near Fishersgate and Station Road
Houses split into flats around the station and harbour often rely on undersized or poorly maintained bathroom extraction, while shared kitchens see heavy daily steam without adequate ventilation. Moisture has nowhere to go, so it settles on ceilings, tiled splashbacks, and cooler external walls behind furniture. Where a past leak from a neighbouring flat has gone unresolved, mould can also spread through party walls unnoticed.

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.
