Leak to dry to treated, one company in Covent Garden

Covent Garden's housing stock is dominated by converted Georgian and Victorian terraces, mansion blocks and former warehouse buildings split into flats above shops, theatres and restaurants. Solid brick walls, minimal insulation, shared party structures and heavy footfall from commercial units below all raise internal humidity, giving mould a steady foothold in bedrooms, bathrooms and living spaces.

Common causes of mould in Covent Garden homes

Solid-wall Georgian and Victorian conversions

Many Covent Garden flats sit within solid brick buildings with no cavity to insulate, so internal wall surfaces run cold and attract condensation. Combined with restricted ventilation in subdivided upper-floor flats, this produces black mould on external walls, in corners and behind wardrobes or beds pushed against outside walls, particularly through autumn and winter.

Flats above shops, restaurants and theatres

Residential upper floors sitting above commercial kitchens, cafes and theatre foyers often absorb rising warmth and moisture through old floors and party walls. Where extraction is inadequate or ageing pipework leaks unnoticed behind fixed shopfronts, penetrating damp develops slowly, surfacing later as mould on ceilings, around chimney breasts and in bathrooms directly above the units.

Listed buildings and sash window condensation

Covent Garden's conservation area status means many buildings keep original single-glazed sash windows, which run cold and stream with condensation in poorly ventilated rooms. This collects in window reveals, frames and behind curtains, while listed-building restrictions can limit straightforward fixes, making it essential to address ventilation and moisture sources rather than the window alone.

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 Covent Garden 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.
