Hillingdon is London’s second-largest borough, from the 1930s Metro-land houses of Ruislip and Northwood to the post-war housing around Hayes and West Drayton. The north is mostly London Clay, where trees cause seasonal movement, while the south sits on river terrace gravels, and the Colne valley to the west is floodplain. We regularly work in HA4, HA6, UB3, UB7, UB8 and UB10.

Common reasons clients in Hillingdon call us
• Cracking linked to London Clay and mature trees
• Movement in 1930s houses and older extensions
• Loft conversions and hip-to-gable extensions
• Rear extensions and wall removals
• 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

My house in Ruislip or Northwood has oak trees nearby. Should I be worried?
Oaks are among the trees most likely to affect clay soils. Cracking that opens in late summer and closes in winter is a typical sign. We inspect, measure the cracks and recommend monitoring or further investigation.

Does the Colne valley affect building work in Uxbridge or West Drayton?
It can. Land near the River Colne is floodplain, so extensions may need a flood risk assessment and foundations designed for softer ground. Flood risk assessments →
