Is Surrey prone to ground movement?
With roughly 17,000 people, Cobham spans postcode districts KT11 in Surrey. We also take enquiries from nearby Esher (3 miles), Weybridge (4 miles) and Leatherhead (4 miles).
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. What you mostly find across Surrey: Victorian and Edwardian villas, 1930s semis and detached houses in the commuter towns, and post-war estates.

Repair options we may recommend
Remove the cause, then repair
Most subsidence is dealt with this way. The drain is repaired or the vegetation managed, the house is watched to confirm it has stabilised, and then the cracks are stitched, repointed and made good inside. It is the least disruptive route and usually the cheapest.
Best for: Clay movement or drain leaks where the cause can be removed
Crack stitching and making good
Once movement has stopped, cracked brickwork is cut along the bed joints, stainless helical bars are bonded in to tie the wall together, and the joints are repointed to match. Inside, plaster is renewed along the crack line before redecoration.
Best for: Category 1 to 3 cracking in walls that are otherwise sound
What to expect when we carry out subsidence repairs
Find the cause
An independent chartered structural engineer inspects the house and, where needed, arranges a drain survey, trial pits or soil tests. We can arrange the engineer. The aim is to know what is moving, and why, before money goes on repairs.
Deal with the cause
Drains are repaired, vegetation is managed on the engineer’s advice, or a foundation scheme is designed if nothing else will work. Where monitoring is recommended, readings run for several months to show the movement has stopped.
Written quote
We price the agreed repair and confirm a fixed price in writing once it is specified. If there is an insurance claim, we can price to the loss adjuster’s or engineer’s schedule instead of our own scope.

Rules for subsidence repairs in England
In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.
Your subsidence repairs questions
How much should I budget for subsidence repairs in Cobham?
Guide prices for subsidence repairs in Cobham start from about £2,800 per property, including VAT, on South East rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Why do houses in Surrey crack?
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. Only an investigation can say why a particular building has moved.
How long should I wait before repairing subsidence cracks?
Usually until the cause has been dealt with and the engineer is satisfied that movement has stopped. On clay that can mean watching the house through a summer and a winter. Repairing too early risks the same cracks opening again.
Does subsidence always need underpinning?
No, most subsidence is repaired without underpinning. When a leaking drain is fixed or nearby vegetation is managed, the ground usually stabilises and the house needs only crack repairs. Foundation work is kept for movement that continues after the cause has gone.
