What should you know about the ground under Sunbury-on-Thames?

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.
From first photo to finished repair
Notify your insurer
Report suspected subsidence to your buildings insurer as soon as you notice it, with dated photos. Do not start permanent repairs first. Check your schedule for the subsidence excess, which is commonly about £1,000.
Loss adjuster and engineer
The insurer usually appoints a loss adjuster, who visits and may bring in an engineer. They record the damage, ask about its history and arrange investigations such as a CCTV drain survey, trial pits and a tree survey.
Repairs and sign-off
With the scope agreed, we carry out the repairs, deal with building control where required and make good. Keep the paperwork, which helps with future insurance and if you sell the house.

Methods for subsidence insurance claim repairs
Pricing the adjuster’s or engineer’s schedule
When the claim reaches the repair stage, we price the schedule of work line by line, at no charge to request. You or the adjuster can compare it against other prices. The figures follow the agreed scope, so nothing is quietly added or left out.
Best for: Homeowners asked to obtain quotes for an agreed scope
Carrying out the agreed repairs
Once the scope is agreed and you instruct us, we carry out the repair, which is often crack stitching, repointing, replastering and redecoration, and sometimes drain or foundation work. We deal with building control where the work needs it and keep the adjuster informed.
Best for: Claims where the repair scope has been settled

Frequently asked questions
How much should I budget for subsidence insurance claim repairs in Sunbury-on-Thames?
There is no charge for us to price an insurer’s schedule in Sunbury-on-Thames. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Sunbury-on-Thames?
We do. Sunbury-on-Thames and the surrounding area are covered, including nearby Ashford and Weybridge. A free initial assessment from your photos is the first step.
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.
Should I repair cracks before claiming?
No, tell your insurer before permanent repairs start. Early repairs can hide evidence the adjuster needs and may affect your claim. Take dated photos, and if a crack is letting in water, ask the insurer about a temporary weatherproofing measure.
Can I choose my own contractor for claim repairs?
Sometimes, depending on your insurer. Some appoint their own contractors, while others let you obtain quotes to the agreed schedule. Ask your loss adjuster. If you are allowed to choose, we can price to the schedule at no charge.
