TW Postcode Area: Damp, Mould & Leak Detection by District

The TW postcode area

The TW postcode area is named after Twickenham and covers Richmond upon Thames west of the river, meaning Twickenham, Teddington, Hampton and Richmond itself (TW9 and TW10), and the London Borough of Hounslow, including Hounslow, Isleworth, Brentford, Feltham and Heathrow (TW6). It crosses into Surrey for Spelthorne (Staines, Ashford, Sunbury, Shepperton) and the north of Runnymede (Egham), with TW19 reaching Wraysbury in Berkshire.

Riverside Thames towns with Georgian and Victorian houses, inter-war suburbia across Hounslow, Feltham and Ashford, and large post-war estates around Heathrow. Much of the area is on the river gravels and floodplain, so high ground water, basements and ground-floor damp come up often alongside the roof and plumbing leaks we trace everywhere.
