Quick answer: Damp & Mould Solutions UK removes and treats black mould at properties in Worthing, and deals with the moisture driving it rather than painting over it. Mould treatment starts from £300, with a fixed price confirmed from photos or a short video before we attend. A leak is not over when the water stops. Mould can start within 48 hours, so we find the source, dry the structure and treat any mould, all with one company. If the cause of the moisture is not clear, a full damp and mould survey is a separate service, £500, or £450 when you book online and pay the deposit. Call 020 3051 8478.

Leak to dry to treated, one company in Worthing

Worthing's housing stock runs from bay-fronted Edwardian terraces in Heene and Broadwater to 1930s semis in Durrington and post-war estates around Salvington and Northbrook. Solid brick walls with no cavity, single-glazed sash windows and poorly ventilated bathrooms retrofitted into small bedrooms all trap moisture, while seafront exposure to salt-laden coastal air makes render and pointing more prone to letting damp track inward.

Common causes of mould in Worthing homes

Bay windows and sash frames in Edwardian terraces

Streets in Heene and Broadwater are lined with Edwardian bay-fronted terraces where original sash windows have swollen, warped or lost their seals over the decades. Condensation streams down the glass on cold mornings and collects in the timber reveals, feeding black mould in the corners and along the sills. Behind curtains and blinds airflow is cut off completely, so spores establish in reveals long before residents notice a problem.

Solid-wall damp in older Worthing homes

Many pre-1930s properties around Tarring and West Tarring have solid brick walls with no cavity to stop moisture migrating through. Where external pointing has failed or render has cracked in the salt air, penetrating damp works inward and shows as mould patches on internal plaster, often near chimney breasts or ground-floor corners. Painting over these patches without addressing the failed brickwork outside means the mould reliably returns within a season.

Under-ventilated bathrooms in converted and extended properties

Loft conversions and rear extensions common in Durrington, Salvington and Findon Valley have added ensuites and family bathrooms that often rely on undersized extractor fans or none at all. Steam has nowhere to go, settling on cold ceiling corners and behind bath panels where it is rarely checked. Left unresolved, mould spreads from the ceiling down tiled walls and into adjoining bedroom walls through shared cavities.

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 Worthing cost?
Mould treatment starts from £300, with a fixed price confirmed from photos or a short video before we attend. If the cause of the moisture is not clear, a full damp and mould survey is a separate service, £500, or £450 when you book online and pay the deposit. 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.
