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 Holloway

Holloway's housing stock is dominated by Victorian and Edwardian terraces converted into flats and HMOs, alongside ex-council low-rise blocks around Hillmarton Road and Camden Road. Solid brick walls, original single-glazed sash windows and high-density multiple occupancy leave little room for ventilation, so condensation and black mould are common on external walls, in bathrooms and behind wardrobes pushed against cold walls.

Common causes of mould in Holloway homes

Victorian terrace conversions and cold bay windows

Many Holloway streets are lined with Victorian terraces split into flats, often with single-glazed bay windows and solid brick walls with no cavity to trap heat. Cold spots around window reveals and external corners encourage condensation, and black mould readily takes hold on plaster, curtains and window frames, especially in upper-floor flats where warm moist air struggles to escape.

Shared houses and HMOs with limited ventilation control

Holloway has a high proportion of shared houses and houses in multiple occupation around Hornsey Road and Tollington Park, where several tenants cook, shower and dry washing indoors without adequate extraction. Landlords are not always quick to address a leaking pipe or blocked gutter, so moisture builds steadily and mould spreads across bedroom walls, wardrobes and bathroom ceilings before anyone takes ownership of the source.

Ex-council blocks and flat roofs prone to penetrating damp

Post-war council blocks around Hillmarton Road and the Andover estate use concrete panel construction with thin original insulation and flat or parapet roofs that are prone to penetrating damp once coverings age. Water tracking through cracked render or a failed roof junction shows up as mould blooming in corners, around window lintels and behind kitchen units long after the original leak has been patched over.

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 Holloway 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.
