What is the ground like in Surrey?
North Surrey sits on London Clay, the south on Weald Clay, with chalk along the North Downs and sands in the west. Large gardens with mature trees on clay make seasonal subsidence a familiar problem.
Ground movement here is more often linked to soils, drains and trees than to mining.
What usually causes cracking in Surrey?
In Surrey, cracking usually comes back to one of these. We rule each in or out before recommending a repair.
- Shrinkable clay drying out in hot summers, worst within reach of tree roots
- Shallow footings and corroded wall ties in older brick houses
- Bay windows built on shallower footings than the main walls
- Garden and boundary walls leaning as tree roots and frost get to them
- Leaking or broken drains washing fine soil out from under footings
What kind of buildings are common here?
Victorian and Edwardian villas, 1930s semis and detached houses in the commuter towns, and post-war estates.

Do repairs in Surrey need approval?
In England, building control approves and inspects structural work such as underpinning; small like-for-like repairs usually do not need it. Party wall notices apply where work affects a shared wall.
Questions about structural repairs in Surrey
Do you cover the whole of Surrey?
Yes. We take enquiries from across Surrey, including Woking, Guildford, Esher and Redhill. A free initial assessment from your photos is the first step.
Is Surrey affected by subsidence?
Much of Surrey sits on clay that shrinks in dry summers and swells in wet winters. Ground movement here is more often linked to soils, drains and trees than to mining. Whether a particular building has moved, and why, needs an investigation on site.
How much do structural repairs cost in Surrey?
It depends on the repair. On South East rates, a standard window or door lintel from about £840 per opening and wall tie replacement on a semi-detached house from about £2,800 per house, including VAT. Your written price follows photos or a survey.
What should I send for a free assessment in Surrey?
Photos of each crack inside and out with a coin or tape for scale, a wider shot showing where it is on the building, your postcode in Surrey, and when you first noticed it. If an insurer is involved, include the claim reference.
