Quick answer: If you have black mould at a property in Blackfriars, we remove it properly and deal with the moisture driving it, rather than painting over it. 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. We start with a damp and mould survey (£500) to find the cause, then treat the mould and fix the source. Call 020 3051 8478.

Leak to dry to treated, one company in Blackfriars

Blackfriars combines converted Victorian warehouses and printing works with mansion block flats, City fringe offices turned into apartments, and newer riverside developments along Blackfriars Road and the Southbank. Solid brick party walls, deep basements and dense multi-storey conversions with limited through-ventilation mean moisture from cooking, bathing and drying washing has few places to escape, encouraging condensation mould on walls, ceilings and behind wardrobes.

Common causes of mould in Blackfriars homes

Converted warehouse and printworks flats

Many Blackfriars homes began life as Victorian printing works or commercial warehouses split into flats. Thick solid brick walls with no cavity, combined with large industrial-style windows, create cold surfaces where warm moist air condenses overnight. We see black mould building up around window reveals, in corners and along external walls, particularly in bedrooms where doors stay shut and airflow is restricted.

Mansion block bathrooms and kitchens

The area's mansion blocks off Fleet Street and Blackfriars Road often have small internal bathrooms and galley kitchens with underpowered or blocked extractor fans. Steam has nowhere to go, settling on tiled ceilings, grout and behind bath panels. Left untreated, this surface mould spreads into adjoining bedrooms through shared walls, and recurring leaks from ageing plumbing in these older buildings add penetrating damp to the mix.

Riverside apartments and basement conversions

Newer riverside blocks near the Southbank and lower ground floor conversions common around Blackfriars can suffer from poor cross-ventilation despite double glazing, trapping humidity indoors. Basement and lower ground flats also face penetrating damp from below-pavement walls and past water ingress, leaving mould behind furniture and fitted units where air barely circulates, even in otherwise well-maintained buildings.

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 Blackfriars 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.
