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.
