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
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

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.
Mitigation and monitoring
The identified cause is dealt with, perhaps a drain repair or tree work, and the house may be monitored for several months, sometimes up to 12, to confirm it has stabilised before repairs are agreed.
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.

Frequently asked questions
How much should I budget for subsidence insurance claim repairs in Warminster?
There is no charge for us to price an insurer’s schedule in Warminster. 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 Warminster?
Yes. We take enquiries from across Warminster, including BA12, and from nearby places such as Westbury and Frome. Send photos for a free initial view and we will tell you what happens next.
Why do houses in Wiltshire crack?
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. Only an investigation can say why a particular building has moved.
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.
What if my subsidence claim is declined?
Ask the insurer for the reasons in writing and check them against your policy wording. You can complain to the insurer and then, if unresolved, go to the Financial Ombudsman Service. If you decide to repair privately, we can give a no-obligation written quote.
