Leak to dry to treated, one company in Holborn

Holborn's housing mix runs from Georgian and Victorian terraces converted into flats to mansion blocks, ex-local authority estates and townhouses squeezed between commercial premises. Many buildings have solid brick walls, original sash windows and basement or lower-ground conversions, all of which restrict airflow and let moisture linger, making condensation and damp-related mould a recurring problem across the area.

Common causes of mould in Holborn homes

Solid-wall Georgian and Victorian terraces

Holborn's older terraces, many now split into flats near Bloomsbury and Gray's Inn, have solid brick walls with no cavity, so they hold less warmth and let condensation form readily on cold internal surfaces. Bedrooms and box rooms with limited ventilation are especially prone, and black mould commonly appears on external walls, in corners and behind wardrobes pushed against unheated masonry.

Basement and lower-ground flat conversions

Many buildings around Clerkenwell and Farringdon have been converted to include basement or lower-ground flats, which sit below or close to street level and are vulnerable to penetrating damp from ground moisture, poor external drainage or ageing tanking. Once water gets in, mould spreads across walls and ceilings, and without fixing the source of ingress it keeps returning after redecoration.

Mansion block bathrooms and sash-window reveals

The mansion blocks and period flats around Russell Square and Holborn Circus often retain original single-glazed sash windows and compact bathrooms with limited or no mechanical extraction. Condensation gathers on cold glass and window reveals, while steam from showers lingers in poorly ventilated bathrooms, leading to persistent mould around frames, sealant and ceiling corners that simple cleaning does not resolve.

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 Holborn 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.
