Leak to dry to treated, one company in Bishopsgate

Bishopsgate's residential stock ranges from converted Victorian warehouse lofts around Devonshire Square to sealed glass apartment towers near Liverpool Street and Broadgate, with older terraces bleeding into neighbouring Spitalfields. Thick solid-brick conversions trap moisture behind exposed brickwork, while modern high-rises lack adequate ventilation, so both extremes generate persistent condensation and black mould despite very different building ages.

Common causes of mould in Bishopsgate homes

Warehouse and loft conversions

Bishopsgate's warehouse-to-loft conversions around Devonshire Square and Artillery Passage feature solid nine-inch brick walls, exposed steel beams and soaring ceilings that were never designed for modern heating and daily living moisture. Cold bridging where steel meets brick, combined with minimal original ventilation, produces condensation and black mould across ceilings, around skylights and behind exposed brick feature walls that owners are reluctant to plaster over.

Sealed high-rise apartments

Newer apartment towers near Liverpool Street and Broadgate were built airtight for energy efficiency, but many rely on trickle vents and passive stack ventilation that gets blocked or switched off, leaving bathrooms and internal bedrooms with nowhere for moisture to escape. En-suite showers without working extraction, and wardrobes built against cold external walls, are common spots for black mould in these sealed, double-glazed flats.

Older terraces on the Spitalfields fringe

Where Bishopsgate meets the older terraced streets of Spitalfields, Georgian and Victorian buildings above shops and offices often have ageing parapets, shared guttering and party walls that let water track down from roof to basement. Lower-ground and basement flats in these buildings suffer penetrating damp and rising mould around window reveals, in bedrooms facing the street and behind furniture pushed against solid, uninsulated external 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.

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 Bishopsgate 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.
