Leak to dry to treated, one company in Chiswick

Chiswick's housing mix runs from Bedford Park's Victorian and Edwardian terraces to riverside cottages at Strand-on-the-Green and interwar mansion blocks near Turnham Green. Solid brick walls, conservation area restrictions on external insulation, and proximity to the Thames all raise the risk of condensation, penetrating damp and mould taking hold on walls, ceilings and behind furniture.

Common causes of mould in Chiswick homes

Bedford Park's solid-wall terraces

Bedford Park's Victorian and Edwardian terraces were built with solid brick walls and no cavity, so they lose heat quickly and condense moisture on cold internal surfaces. Conservation area rules often restrict external wall insulation and render, leaving many homes reliant on heating and ventilation alone. Black mould commonly develops on north-facing bedroom walls, behind wardrobes and around original sash windows where draughtproofing has cut airflow.

Riverside damp near Strand-on-the-Green

Properties along Strand-on-the-Green and Corney Reach sit close to the Thames, where a high water table and periodic flooding push moisture into ground floor walls and solid floors. Penetrating and rising damp here is more persistent than typical condensation, staining plaster and skirting boards and feeding mould growth behind sofas and low furniture. Treating the surface mould without addressing the damp source usually sees it return within weeks.

Converted flats and mansion blocks with poor airflow

Many of Chiswick's larger Edwardian houses near Turnham Green and Grove Park have been split into flats, often with internal bathrooms and kitchens lacking working extractor fans. Retrofitted double glazing has sealed these homes against draughts but also trapped humid air, so mould appears around window frames, in bathroom corners and on ceilings above showers. Restoring proper ventilation is essential alongside any mould treatment to stop it recurring.

★★★★★

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 Chiswick 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.
