Leak to dry to treated, one company in Canonbury
Canonbury's housing stock is dominated by Georgian and Victorian terraces, many converted into flats, alongside grand squares like Canonbury Square and Compton Terrace. Solid brick walls, original single-glazed sash windows and basement or lower-ground-floor conversions are common, and this combination of ageing fabric, restricted ventilation and below-grade living space makes the area particularly prone to condensation and mould.

Common causes of mould in Canonbury homes
Converted flats with poor airflow
Many Canonbury terraces were split into flats decades ago, often leaving bathrooms and kitchens without working extractor fans or direct outside walls. Moist air from cooking, bathing and drying clothes has nowhere to escape, so it settles on cooler surfaces such as external walls and ceilings. Over time this produces persistent black mould in corners, above skirting boards and around window reveals, particularly in smaller upper-floor flats.
Basement and lower-ground-floor damp
Canonbury Square and the surrounding streets include numerous basement and lower-ground conversions where floors sit close to or below external ground level. Without effective tanking or a functioning damp-proof course, groundwater penetrates walls and floors, creating conditions for black mould behind furniture, under stairs and along skirting. These spaces also trap humid air, so mould frequently reappears even after surface cleaning unless the moisture source is addressed.
Original sash windows and solid Victorian walls
The single-glazed timber sash windows typical of Canonbury's Victorian and Georgian properties are prone to condensation forming on cold glass and frames, especially in bedrooms overnight. Combined with solid brick walls that lack cavity insulation, cold bridging around window reveals and external corners encourages mould growth on plaster and paintwork. Left untreated, staining spreads from window sills onto surrounding walls and ceilings.
