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.

What our customers say

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: Wiping mould off with bleach and repainting hides it for a few weeks, then it returns. Mould is a moisture problem, so unless the condensation, damp or leak feeding it is fixed, it always comes back.

Frequently asked questions

How much does mould removal in Portslade cost?
It depends on the cause and extent. We start with a damp and mould survey at £500 to find the moisture source, then quote the treatment. Treating the surface without the source means the mould returns.
Is black mould in my home dangerous?
Black mould affects indoor air quality and is best removed promptly. We treat the mould and fix the moisture driving it, so the problem is dealt with at the cause.
Will the mould come back after treatment?
Not if the moisture source is fixed. We find and address the cause, whether condensation, penetrating damp or a leak, rather than just cleaning the surface.
Do you find what is causing the mould?
Yes. Every job starts by identifying why the mould is there, using a proper damp and mould survey, so the treatment lasts.
