Leak to dry to treated, one company in Islington

Islington's housing is dominated by Georgian and Victorian terraces converted into flats, alongside dense postwar council estates around Finsbury Park and Caledonian Road and newer infill developments. Solid brick walls, shared party structures, small converted bathrooms and limited external wall space for insulation all combine to trap moisture, making condensation and damp-related mould a recurring problem across the borough.

Common causes of mould in Islington homes

Solid-wall terraces in Barnsbury and Canonbury

Much of Islington's period housing in Barnsbury and Canonbury was built with solid brick walls and no cavity, so external moisture passes through more readily than in cavity-wall homes. Conservation area rules often restrict external insulation or render changes, leaving internal wall surfaces prone to condensation and penetrating damp, which shows up as black mould around chimney breasts, bay windows and cold external corners.

Converted period houses with poor ventilation

Large numbers of Victorian and Georgian houses across Highbury and Holloway were subdivided into flats decades ago, often leaving bathrooms and kitchens without windows or working extraction into a shared roof void. Cooking and bathing moisture has nowhere to escape, so it settles on ceilings and tiled walls, and mould frequently spreads into adjoining bedrooms through shared party walls and floors.

Postwar estates and cold bridging

Council-built blocks around Finsbury Park and Caledonian Road were largely constructed in concrete and brick with minimal insulation at window reveals and lintels, creating cold bridges. Warm indoor air condenses fastest at these weak points, so mould commonly forms in corners behind wardrobes and around window frames in bedrooms, often mistaken for a leak when the real cause is trapped condensation.

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 Islington 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.
