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

New Cross mixes Victorian terraces converted into flats around Telegraph Hill and Hatcham, dense student and young-professional lets near Goldsmiths, and post-war council blocks off New Cross Road and towards Evelyn. Solid brick walls, ill-fitting sash windows and estates with poor cross-ventilation all trap moisture, making condensation and damp-related mould a routine call-out across the area.

Common causes of mould in New Cross homes

Solid-wall Victorian terraces with no cavity insulation

Much of New Cross Gate and Telegraph Hill was built as solid brick terraces, later carved into flats with shared bathrooms and kitchens. Without a cavity to slow heat loss, internal wall surfaces run cold, and warm moist air condenses on them overnight. We see black mould building up in corners, behind wardrobes pushed against external walls, and around original sash windows where draught-proofing was never fitted.

HMOs and student conversions near Goldsmiths

The concentration of shared houses and student lets around Goldsmiths means more occupants, more cooking, showering and drying of washing per property, often with extractor fans missing, blocked or switched off to save noise or energy. Bedrooms converted from box rooms and lofts get little airflow, so mould develops on ceilings and behind furniture. Tenant turnover also means damp problems often go unreported until they are well established.

Post-war council flats and estate blocks around Evelyn and New Cross Road

Concrete and system-built blocks in this part of New Cross suffer from cold bridging at window reveals, corners and behind kitchen units, where surface temperatures drop enough for condensation to form even with reasonable heating. Bathrooms without working extraction and communal stairwells that let cold air into flats compound the issue, leading to recurring black mould that repainting alone never actually resolves.

Jensen B, via Google

★★★★★

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 New 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.
