Repair options we may recommend
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
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.
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.

Your subsidence insurance claim repairs questions
How much should I budget for subsidence insurance claim repairs in Harrow?
There is no charge for us to price an insurer’s schedule in Harrow. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Why do houses in Greater London crack?
Most of Greater London sits on London Clay, among the most shrinkage-prone ground in the UK, with river gravels along the Thames. Subsidence claims here are among the most frequent in the country, especially after dry summers and near street and garden trees. Only an investigation can say why a particular building has moved.
What if my subsidence claim is declined?
Ask the insurer for the reasons in writing and check them against your policy wording. You can complain to the insurer and then, if unresolved, go to the Financial Ombudsman Service. If you decide to repair privately, we can give a no-obligation written quote.
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.
