Methods for subsidence insurance claim repairs
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
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.
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.
Schedule of repairs
The adjuster or engineer issues a schedule of the work needed. We can price to your loss adjuster’s or engineer’s schedule, and confirm a fixed price in writing, with any betterment shown as a separate quote.

Frequently asked questions
How much should I budget for subsidence insurance claim repairs in Horsham?
There is no charge for us to price an insurer’s schedule in Horsham. 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 Horsham?
Yes. We take enquiries from across Horsham, including RH12, and from nearby places such as Crawley and Horley. Send photos for a free initial view and we will tell you what happens next.
Why do houses in West Sussex crack?
North West Sussex around Crawley and Horsham sits on Weald Clay, the South Downs are chalk, and the coastal plain has brickearth and gravels. The Weald Clay is prone to shrink-swell movement near trees. Only an investigation can say why a particular building has moved.
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.
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.
