Sutton has Victorian and Edwardian houses around Carshalton and Sutton, and large areas of 1930s semi-detached housing. Its ground changes from London Clay in the north, where trees cause seasonal movement, through sand to chalk on the edge of the North Downs in the south, so the right foundation and drainage design depends on exactly where you are. We regularly work in SM1, SM2, SM3, SM5, SM6 and KT4.

Common reasons clients in Sutton & Cheam call us
• Cracking linked to London Clay and nearby trees
• Movement in bays and older extensions
• Loft conversions and rear extensions
• Soakaway and drainage questions on chalk sites
• 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

Will a soakaway work at my house in Sutton or Belmont?
Often, yes. The chalk in the south of the borough usually drains well, but it can contain dissolution features. An infiltration test confirms the soakaway size and that it can be kept a safe distance from foundations. SuDS and soakaway design →

Is the ground the same across Sutton?
No. Worcester Park and the north are mostly on London Clay, while the south is on chalk. The foundation design for an extension in North Cheam can be quite different from one in Belmont.
