Why does the ground in Cornwall matter for subsidence insurance claim repairs?
Cornwall is mostly granite and slate with little shrinkable clay, so clay subsidence is less common than in the south-east. Historic tin and copper mining has left shafts and workings in places such as Camborne and Redruth, and mining searches are routine there.
Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. Across Cornwall, most homes are granite and slate-stone cottages, cob buildings, Victorian terraces and post-war estates.
Which repair method suits a home in Cornwall?
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

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.

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.
