Leak to dry to treated, one company in Clerkenwell

Clerkenwell's housing stock is a patchwork of converted Victorian warehouses and print works turned loft apartments, Georgian terraces, Peabody Trust estates and mansion blocks. Exposed brick, solid walls without cavity insulation, and industrial steel-framed windows create cold surfaces where warm, moist air condenses, while ageing pipework in older conversions adds a steady source of hidden damp.

Common causes of mould in Clerkenwell homes

Warehouse and loft conversions with cold bridging

Many Clerkenwell flats occupy converted Victorian warehouses and print works, prized for exposed brick and original steel-framed windows. These features are poor insulators, so internal surfaces run cold against warm indoor air, and condensation forms on window reveals, brick walls and ceilings. Open-plan layouts with limited ventilation let moisture drift and settle, encouraging black mould in corners, behind wardrobes and along cold external walls.

Georgian and Victorian terraces with solid walls and basements

Clerkenwell's older terraced houses have solid brick walls, timber floors and semi-below-ground basement rooms, all vulnerable to penetrating damp through ageing pointing, cracked render or failed damp-proof courses. Water tracks through masonry and settles at skirting level or in basement corners, feeding surface mould that returns each winter unless the actual moisture route through the wall or floor is traced and closed off.

Peabody estates and mansion block flats with weak ventilation

The area's Peabody Trust estates and purpose-built mansion blocks pack bathrooms and kitchens into compact layouts, often with a single small window or an underperforming extractor fan. Steam from cooking and showering has nowhere to escape, so it condenses on tiled walls, ceilings and behind furniture pushed against external walls, producing recurring mould in bedrooms and bathrooms that redecorating alone never permanently resolves.

★★★★★

I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.

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 Clerkenwell 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.
