Cavity wall insulation extraction in Balham & Wandsworth

Postcodes: SW12, SW17, SW18

Balham, Tooting and parts of Wandsworth combine Victorian terraces (often solid-walled) with later extensions and interwar blocks that do have cavities. Extraction only applies where fill was actually installed.

What to watch for in SW12 / SW17 / SW18

Mixed construction. Map which elevations were filled – especially side returns and rear extensions on older houses.
High sale volumes. Survey flags late in a chain are common; start paperwork and a specialist report early if damp is linked to cavity fill.
Flats. External walls of converted houses and mansion blocks may be the freeholder's responsibility – check the lease before instructing work.

What to include in your enquiry

Postcode and property type
When the insulation was installed (if known) and any CIGA or scheme paperwork
