Leak to dry to treated, one company in Cannon Street

Cannon Street sits in the historic core of the City of London, mixing solid-walled Georgian and Victorian buildings with converted warehouse lofts and modern riverside apartments near the Thames. Many properties were built without cavity walls or adequate ventilation and have since been subdivided into flats above shops and offices, trapping moisture and making condensation-driven mould a recurring problem for residents and landlords.

Common causes of mould in Cannon Street homes

Converted flats above shops and offices

Many Cannon Street homes are upper-floor conversions carved out of older commercial buildings, often with a single bathroom and kitchen vented poorly or not at all. Cooking and showering push moisture into solid brick walls that cannot breathe, and it condenses on cold plaster. The result is black mould creeping across ceilings, corners and behind wardrobes pushed against external walls.

Riverside damp near the Thames

Buildings close to Upper Thames Street and the river frontage sit on ground that stays damp for much of the year, and older basements and ground floors can draw moisture upward through solid masonry. Combined with ageing pointing and gutters, this penetrating and rising damp feeds mould growth around skirting boards, behind furniture and low down on party walls shared with neighbouring properties.

Single-glazed sash windows and cold bridging

Georgian and Victorian buildings around Cannon Street commonly retain original timber sash windows with thin or single glazing, creating cold surfaces where warm, moist indoor air condenses. Bedrooms and bathrooms with these original windows are particularly prone to black spotting on frames, reveals and nearby plasterwork, especially once curtains or blinds are drawn and airflow across the glass is reduced overnight.

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 Cannon Street cost?
Mould treatment starts from £300, with a fixed price confirmed from photos or a short video before we attend. If the cause of the moisture is not clear, a full damp and mould survey is a separate service at £450. 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.
