Leak to dry to treated, one company in Herne Hill

Herne Hill's housing spans grand Victorian villas around Sunray Gardens and Half Moon Lane, terraces converted into flats near the station, and 1930s semis towards Tulse Hill. Many properties have solid brick walls, single-glazed sash windows and lower-ground flats, so cold bridging, poor ventilation and old damp-proofing combine to make condensation and black mould persistent problems.

Common causes of mould in Herne Hill homes

Converted Victorian villas with poor ventilation

Many of Herne Hill's large Victorian villas near Sunray Gardens and Herne Hill Road were divided into flats decades ago, often leaving bathrooms and kitchens without proper extraction. Steam and cooking moisture have nowhere to escape, settling on cold ceilings and ledges above windows. In upper-floor flats this shows as black speckling in bedrooms and behind wardrobes pushed against external walls.

Solid-wall terraces and cold-bridging condensation

The solid brick terraces lining Half Moon Lane and the streets around Poets' Corner were built with no cavity for insulation, so internal wall surfaces stay noticeably colder than the room air. Where furniture or a bed sits close to an outside wall, airflow is blocked and mould forms in the gap. Corners near single-glazed sash windows are usually the first place staining appears.

Basement and lower-ground flats with penetrating and rising damp

Herne Hill has a good number of lower-ground and basement flats, particularly around the station and towards Brockwell Park, where old or failed tanking lets penetrating and rising damp into the fabric of the building. This shows as mould creeping up skirting boards, along ceiling edges below the pavement, and behind sofas or storage boxes stacked against damp external walls.

★★★★★

I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.

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 Herne 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.
