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

Frequently asked questions
How much should I budget for subsidence insurance claim repairs in Seaham?
There is no charge for us to price an insurer’s schedule in Seaham. 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 Seaham?
We do. Seaham and the surrounding area are covered, including nearby Houghton-le-Spring and Sunderland. A free initial assessment from your photos is the first step.
Why do houses in County Durham crack?
Much of County Durham sits on the Durham Coalfield, worked for centuries, often under a cover of glacial clay. Many former pit villages have recorded mine workings, and coal mining searches are standard for property here. Only an investigation can say why a particular building has moved.
What is betterment in a subsidence claim?
Betterment is any improvement beyond restoring the home to its condition before the damage, such as upgrading finishes or redecorating extra rooms. The insurer does not normally pay for it. We price betterment as a separate written quote, so it is clearly kept outside the claim.
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.
