Leak to dry to treated, one company in Primrose Hill

Primrose Hill is dominated by stucco-fronted Victorian and Georgian terraces, many now split into flats, alongside grand villas backing onto the park and mansion blocks towards Regent's Park Road. Solid brick walls, original sash windows and conservation area restrictions on external alterations mean condensation and penetrating damp are common, and mould readily takes hold in poorly ventilated rooms.

Common causes of mould in Primrose Hill homes

Solid-wall terraces and condensation mould

Much of Primrose Hill's period housing was built with solid brick walls and no cavity, so internal surfaces run cold and condensation forms easily on north-facing bedroom and living room walls. Once moisture repeatedly settles on plaster or behind wardrobes and headboards, black mould develops. Improving ventilation and insulating internally, rather than simply repainting, stops it recurring.

Flat conversions with poor bathroom and kitchen extraction

Many of the area's grand houses have been divided into flats, often with bathrooms and kitchens fitted into former box rooms or landings without adequate extractor provision. Steam has nowhere to escape, so mould spreads across ceilings, tile grout and door frames. We fix or add proper extraction alongside treatment so the moisture source, not just the mould, is resolved.

Sash windows and penetrating damp behind furniture

Original timber sash windows, prized for their character, are frequently draughty and poorly sealed, letting damp track into surrounding plaster and window reveals. Combined with furniture pushed against external walls in period rooms, this creates cold, unventilated pockets where black mould grows unnoticed behind sofas and beds. We identify the water source, remediate it and treat affected surfaces thoroughly.

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 Primrose Hill 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.
