Fees for structural crack and building damage claims: a cost guide

Why structural claims cost more to handle

A burst pipe has an obvious cause; a cracked wall does not. The expert acting for you must first establish whether the damage stems from an insured event such as subsidence, heave, impact or escape of water, then show that the proposed repair actually addresses that cause. That means reviewing the policy definitions and exclusions, attending site meetings with the insurer's adjuster and engineer, scrutinising trial pit and borehole results, reading monitoring data and costing a full reinstatement scheme.

These claims also run for months, sometimes more than a year, with long gaps while movement is monitored. Every extra meeting, report review and round of negotiation consumes time, which is reflected in the fee structure.

Order-of-magnitude fee bands

The table below sets out indicative contingency percentages observed on the market for structural property claims. They are not official and not a legal scale; they simply help you place a quote in context. The bands apply in your own currency and are degressive, with the percentage falling as the claim value rises.

Structural claims often sit in the middle and upper bands because underpinning, drainage replacement and full redecoration can quickly reach six figures, especially on older or larger buildings.

Indicative amounts, to be checked with each expert.

Fee models and their trade-offs

Because the outcome of a structural claim is uncertain and the timeline long, firms vary more in how they charge for this type of work than for simpler claims.

• Percentage of the total settlement: aligns the expert with the size of the outcome, but includes sums the insurer may have paid anyway.
• Percentage of the additional amount secured: attractive when the insurer has already accepted liability and proposed a scheme you consider inadequate.
• Hourly or day rates: common for a preliminary review of a declined claim or for expert input before an ombudsman complaint.
• Hybrid arrangements: a modest fixed fee for the initial assessment, then a lower contingency percentage if the claim proceeds.
• Minimum fees and expense recovery: check for mileage, printing, attendance at extra site meetings and third-party reports.

Engineering and investigation costs are a separate line

The fee of a public adjuster or loss assessor rarely includes the cost of your own structural engineer, drainage survey, arboricultural report or soil testing. If you need an independent technical opinion to challenge the insurer's findings, those specialists will invoice separately, often on a fixed fee per report or on hourly rates.

When the claim is accepted, the insurer normally pays for the investigations it commissions and, under many buildings policies, for professional fees necessary to reinstate the property, such as structural engineers, building surveyors and building control charges. That professional fees cover typically relates to the repair itself rather than to the cost of the expert negotiating on your behalf, so confirm the wording before assuming any reimbursement.

Is there an equivalent of an expert fee guarantee?

Unlike some European markets, English-speaking household policies rarely contain a specific guarantee that refunds the fees of an assessor chosen by the policyholder. Commercial property policies may include a claims preparation costs clause, usually subject to a stated limit, which can contribute to the cost of quantifying a loss. Legal expenses cover attached to some home policies may help with disputes but generally does not fund a loss assessor. Read the schedule and ask your broker in writing.

Three illustrative scenarios

Small: cracks around a window caused by a leaking downpipe, repaired by stitching and redecoration for around 8,000. The work is limited, the fee might reach 1,000 to 1,200 including minimum charges, and the case for an expert is weak unless liability is disputed.

Medium: subsidence affecting a rear extension, with drainage repairs and partial underpinning settled at 90,000 after the insurer first offered superstructure repairs worth 40,000. At 9 % of the total, the fee is 8,100 plus tax; at 20 % of the 50,000 increase, it would be 10,000. The second model is more expensive here, which shows why the base matters.

Large: a terrace of rental properties with significant movement, settled at 600,000. A rate of 5 % gives 30,000, and the expert will likely coordinate several engineers and contractors. All figures are illustrative only.

Questions to ask before signing a mandate

A clear written proposal protects both sides. Make sure the engagement letter answers each of the following, and keep a copy with your claim file.

• Which tasks are included: site meetings, monitoring reviews, contractor tendering, supervision of works?
• Is the percentage applied to the whole settlement, the increase or the building element only?
• Who appoints and pays any independent engineer, and at what estimated cost?
• What happens if the claim is declined, withdrawn or transferred to another insurer after a policy change?
• Are taxes such as VAT, GST or HST included or added?
• In the US, does the contract comply with your state's rules on public adjuster fees and cancellation rights?

Comparing experts on more than price

In structural claims, technical credibility often matters more than a percentage point. Ask how many subsidence or structural claims the firm has handled, which engineers it works with, and how it has dealt with causation disputes. A good expert will be candid about the weak points of your case and the realistic range of outcomes. Avoid anyone who promises underpinning or a particular settlement before seeing the investigation results, or who suggests concealing previous cracking.

On structural claims, budget for two things: the claims expert's fee and any independent technical evidence. expertdassure.com suggests agreeing both in writing before investigations begin.
