What should you know about the ground under Wiltshire?
Southern Wiltshire is chalk, while the north around Swindon, Chippenham and Trowbridge sits on Oxford and Kimmeridge Clays that are prone to seasonal movement near trees. Bath stone was mined underground around Corsham.
Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Wiltshire: stone cottages, railway terraces in Swindon, and large post-war and new-build estates.

Which repair method suits a home in Wiltshire?
Betterment priced separately
Many homeowners take the chance to do extra work while trades are on site, such as redecorating whole rooms or upgrading finishes. That betterment sits outside the claim, so we price it as a separate written quote, keeping the claim work clear.
Best for: Extra work you choose beyond the agreed claim repair
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

Subsidence insurance claim repairs in Wiltshire: questions and answers
Is the ground in Wiltshire prone to subsidence?
Southern Wiltshire is chalk, while the north around Swindon, Chippenham and Trowbridge sits on Oxford and Kimmeridge Clays that are prone to seasonal movement near trees. Bath stone was mined underground around Corsham. Ground movement here is more often linked to soils, drains and trees than to mining. Only an investigation on site can say why a particular building has moved.
How much will subsidence insurance claim repairs cost in Wiltshire?
The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
How long does a subsidence claim take?
Many claims take several months to over a year, mostly because of investigations and monitoring. On clay, insurers often want readings across a summer and winter before agreeing a repair. The repairs themselves are usually much quicker once the scope is settled.
How do I make a subsidence claim?
Contact your buildings insurer as soon as you suspect subsidence, with dated photos and a note of when the cracks appeared. They will usually appoint a loss adjuster to visit. Do not start permanent repairs before the insurer has seen the damage.
Will the insurer pay for underpinning?
Only if investigations show it is needed, which is less common than many people expect. Most subsidence claims are fixed by dealing with the cause, such as a drain or tree, and then repairing the cracks. The insurer’s engineer recommends the method.
