Quick answer: If you have black mould at a property in Kings Cross, 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 Kings Cross

Kings Cross combines dense Victorian terraces converted into flats, Georgian townhouses around Bloomsbury and Somers Town, post-war council blocks, and glass-fronted new builds near Granary Square. This mix of old solid-wall stock with poor ventilation and modern airtight flats with limited airflow means condensation and mould are common, whatever the building's age or price point.

Common causes of mould in Kings Cross homes

Converted Victorian terraces with shared bathrooms

Many Kings Cross terraces on streets around Barnsbury and Pentonville were split into flats decades ago, often leaving bathrooms and kitchens without proper extraction. Cooking and washing generate moisture that has nowhere to go, settling on cold external walls and ceilings. We treat the resulting black mould and fit ventilation suited to the flat's layout, not just a generic fan.

Georgian solid-wall buildings and penetrating damp

The Georgian and early Victorian houses around Bloomsbury and Somers Town rely on solid brick walls, ageing parapets and cast-iron guttering. Once pointing, render or a gutter joint fails, rainwater tracks through the wall and mould appears on internal plaster, often around window reveals. We trace the entry point outside before treating the mould, so it does not simply return after redecoration.

New-build and refurbished flats near Granary Square

Newer, well-insulated flats near King's Cross Central and Granary Square trap moisture instead of losing it through draughts, and trickle vents are frequently left closed or blocked. Bedrooms and behind wardrobes pushed against external walls are common trouble spots. We treat surface mould and advise on ventilation and heating patterns that suit airtight construction, preventing recurrence.

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 Kings Cross 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.
