Leak to dry to treated, one company in Alexandra Palace

Alexandra Palace's housing is a mix of Victorian and Edwardian terraces climbing the hill around the park, purpose-built mansion flats, and the low-rise Noel Park and Alexandra Park estate homes nearby. Many properties retain original solid brick walls, single glazing and older roofing details, which combine with steep gardens and poor ventilation to trap moisture and encourage recurring mould.

Common causes of mould in Alexandra Palace homes

Solid-wall Victorian terraces holding damp

The Victorian and Edwardian terraces surrounding Alexandra Palace were built with solid brick walls and no cavity insulation, so cold spots form easily on north-facing rooms and stairwells. Once penetrating damp or condensation takes hold, black mould spreads across plaster and skirting boards, and because these walls hold moisture longer than modern cavity construction, treatment must include drying the fabric itself, not just cleaning visible spots.

Converted flats with restricted airflow

Many of the area's grander houses near the park have been split into flats, often losing through-ventilation as chimneys were sealed and internal doors added. Bathrooms and box bedrooms in these conversions frequently lack working extractor fans, so steam and daily moisture linger, settling as mould on ceilings, around window reveals and behind wardrobes pushed against external walls.

Hillside drainage and older roofs

Streets rising towards Alexandra Palace itself sit on sloping ground, and older roof coverings, valley gutters and Victorian pointing on these properties are prone to slow water ingress after heavy rain. This penetrating damp often shows up as staining and mould on upper-floor ceilings and around chimney breasts well before residents notice a leak, making early inspection and repointing important to stop it recurring.

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 Alexandra Palace 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.
