Which repair method suits a home in Lisburn?
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 happens when we carry out subsidence insurance claim repairs in Lisburn?
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.

Subsidence insurance claim repairs in Lisburn: questions and answers
How much will subsidence insurance claim repairs cost in Lisburn?
There is no charge for us to price an insurer’s schedule in Lisburn. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Is the ground in County Antrim prone to subsidence?
County Antrim is largely basalt over chalk, with soft estuarine 'sleech' along Belfast Lough that is notorious for settlement. Historic salt mining is recorded near Carrickfergus. Only an investigation can say why a particular building has moved.
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.
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.
