Where the expert's time goes on a leak
Water claims look simple but can spread well beyond the visible stain. An expert acting for you reviews the policy for definitions of escape of water, exclusions for gradual leaks, wear and tear and failed sealant, and any trace and access cover that pays to find the source. They then document the damage, often with moisture readings, organise or check the drying programme, prepare a repair estimate including flooring, kitchens and redecoration, and list damaged contents.
Negotiation tends to focus on how far the damage extends, whether matching floors or kitchen units must be replaced in full, and whether the leak was sudden enough to fall within cover. Those debates are where an expert's fee is earned.
Hidden damage and drying
Water travels under floors, behind tiling and into insulation. Inadequate drying can lead to mould and secondary damage months later. Moisture mapping, drying certificates and photos at each stage are valuable evidence. Some policies cover alternative accommodation while the property is dried, and claiming it correctly can make a significant difference to the household.
| Claim settlement | Indicative fee range | Typical water damage claim |
|---|---|---|
| Up to 25,000 | 10 % to 15 % | Kitchen or bathroom leak, one or two rooms |
| 25,001 to 50,000 | 9 % to 12 % | Burst pipe across several rooms with contents |
| 50,001 to 100,000 | 8 % to 10 % | Whole-floor damage, alternative accommodation |
| 100,001 to 250,000 | 6 % to 9 % | Multiple flats or extensive structural drying |
| 250,001 to 500,000 | 5 % to 7 % | Large homes, commercial premises |
| 500,001 to 1,000,000 | 3.5 % to 6 % | Blocks of flats, offices |
| 1,000,001 to 5,000,000 | 2 % to 4 % | Commercial buildings with business interruption |
| Over 5,000,000 | 1 % to 2.5 %, negotiated | Major commercial or portfolio losses |

Indicative percentage bands
The table below shows an order of magnitude observed on the market for contingency fees on water damage claims, applied in local currency. It is not official or regulated and decreases as the claim value increases.
Most domestic escape of water claims fall in the lowest two bands, which explains why percentages around 10 % to 15 % are frequently quoted, sometimes with a minimum fee. Large losses, such as a flat above leaking into several units, can move into higher bands with lower rates.
Calculation methods and extras
On water claims, the exclusion of the insurer's own contractor costs from the fee base can make a material difference.
- Percentage of the full settlement, including trace and access and drying costs.
- Percentage excluding costs the insurer pays directly to its own drying contractors.
- Percentage of the increase over an offer already received.
- Fixed fee for a contained leak with clear evidence.
- Hourly fee for a review of a declined gradual-leak claim.
- Minimum fee and taxes such as VAT, GST or HST, plus specialist costs like leak detection agreed in advance.
Does the policy pay for your own expert?
Household policies generally do not pay the fees of an expert you hire. Trace and access cover pays for locating the leak and making good, not for representation. Professional fees cover in buildings sections generally relates to surveyors or engineers needed for reinstatement.
For landlords, blocks of flats and businesses, a claims preparation costs extension may contribute within a limit, and legal expenses cover might assist with a dispute with a neighbour whose leak caused the damage. Check the schedule and conditions before counting on any reimbursement.
Is it worth it? Three water claims
Leaking washing machine damaging a kitchen floor, insurer offers 3,000: a minimum fee of 750 to 1,000 would absorb most of any gain, so negotiating directly is usually best.
Burst pipe in a loft affecting ceilings and two bedrooms, insurer offers 12,000, expert secures 18,500 after documenting damage to insulation, flooring and contents. At 12 % of the total the fee is 2,220; at 20 % of the 6,500 increase it is 1,300.
Leak from an upstairs flat damaging three units and common areas, settled at 120,000. At 7 % the fee is 8,400. All figures are illustrative.
What to verify in the contract
Read the engagement letter carefully, ideally after the emergency is under control and the property is safe. Look for:
- The rate and the exact base, including treatment of drying and trace and access costs.
- Whether advances or offers made before the appointment are excluded.
- Minimum fees, expenses and specialist costs.
- Cancellation rights and the consequences of ending the contract.
- In the US, compliance with state rules on public adjuster contracts and fees.
Choosing a water damage specialist
Experience with escape of water claims, moisture assessment and drying protocols is more valuable than a slightly lower rate. Ask how the expert handles gradual-leak objections and who will visit the property. Check licensing where it applies and request references. Be cautious with promises of a guaranteed payout or encouragement to claim old damage as new; misrepresentation can lead to the claim being refused and the policy cancelled.
Whatever you decide, keep moisture readings, drying certificates, plumber invoices and photos of the source of the leak. These records help you negotiate directly with the insurer and also allow any expert you later appoint to give you a realistic view of the likely improvement, and therefore of whether their fee is justified.

Frequently asked questions
Is trace and access part of the expert's fee base?
It can be. Ask whether the percentage applies to trace and access and drying costs, especially if the insurer pays its own contractors directly.
Will my insurer pay for a loss assessor on a leak?
Household policies rarely do. Some commercial or landlord policies have a claims preparation costs extension.
Is a gradual leak covered?
Often not. Many policies exclude damage from gradual leaks or failed seals, though wording varies and some exceptions exist.
When is an expert most useful on a water claim?
On larger losses, disputed extent of damage, gradual-leak refusals and claims involving several properties.
Water damage claims are common, but the fee for an expert only makes sense when the realistic improvement clearly exceeds it. expertdassure.com recommends checking the fee base carefully, particularly for drying and trace and access costs.
