Repair options we may recommend
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
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
What to expect when we carry out subsidence insurance claim repairs
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.
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.

Your subsidence insurance claim repairs questions
How much should I budget for subsidence insurance claim repairs in Caernarfon?
There is no charge for us to price an insurer’s schedule in Caernarfon. 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 Caernarfon?
Yes, Caernarfon is covered, along with postcode districts LL55. We also cover nearby Llangefni and Bangor.
Why do houses in Gwynedd crack?
Gwynedd and Anglesey are mostly hard rock with glacial deposits, so clay shrinkage is uncommon. Historic slate quarrying and metal mining have left tips and workings in places. 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.
