Chiswick and Isleworth have Victorian and Edwardian houses and riverside properties along the Thames, while Hounslow and Feltham are largely 1930s and post-war housing. Much of the borough sits on river terrace gravels over London Clay, and riverside sites can be affected by flooding and high groundwater. We regularly work in W4, TW3, TW5, TW7, TW8 and TW13.

Common reasons clients in Hounslow & Chiswick call us
• Cracking in Victorian and Edwardian houses in Chiswick
• Defects in riverside and older properties
• Rear extensions and wall removals
• Loft conversions in 1930s semi-detached houses
• Pre-purchase checks after a RICS survey flags a concern

Because we also design drainage, we can identify when a leaking drain is behind the movement and design the fix.

Local questions

I live by the river at Strand-on-the-Green or Isleworth. Will my extension need a flood risk assessment?
Very likely. Much of the Thames riverside is in a flood zone, and planning applications for extensions there usually need one. We prepare flood risk assessments alongside the structural design. Flood risk assessments →

I’m buying a 1930s house in Hounslow or Feltham with an old rear extension. Should I worry?
Older extensions were often built on shallow foundations and sometimes without approval. Cracking where the extension meets the house is common. We check whether the movement is ongoing and whether the extension is adequately built.

Guide prices: specific inspection of one defect £950 + VAT, general inspection of the whole property approx. £1,700 + VAT.
