Insurance guide
The adjuster's estimate is lower than my contractor's. Now what?
Compare the two estimates line by line rather than total to total. Gaps on water losses almost always trace to a handful of omitted items, drying equipment days, antimicrobial treatment, detach-and-reset labor, and hidden moisture found after demolition, each of which can be added through a documented supplement.
A gap between the carrier's estimate and your contractor's is normal and usually fixable. Adjusters write their scope from one visit, often before any wall is opened, so their estimate reflects what was visible that day. The supplement process exists precisely because water damage reveals itself over the following week.
First, confirm what kind of gap it is
Two different problems look identical on the bottom line. If the carrier's replacement cost total is close to your contractor's but the check is much smaller, you are looking at depreciation holdback, which is a payment-timing issue rather than a scope dispute.
If the carrier's replacement cost total itself is well below your contractor's, that is a genuine scope disagreement, and the rest of this guide applies. Check which one you have before spending energy on the wrong argument.
Line items most often missing on water losses
Ask your contractor to mark up the carrier's estimate and show which items are absent or underpriced. These are the recurring omissions on water claims.
- Drying equipment priced for fewer days than it actually ran, the daily logs settle this
- Antimicrobial application after Category 2 or 3 water
- Detach and reset of toilets, vanities, cabinets, and appliances to dry behind them
- Moisture mapping and monitoring labor across the drying period
- Containment barriers and negative air where demolition was needed
- Protective equipment and lawful disposal on contaminated water losses
- Debris hauling and dumpster cost for removed drywall, carpet, and pad
- Baseboard and trim removal and replacement, often omitted on cabinetry-adjacent walls
- Floor prep and transitions after flooring removal, not just the flooring itself
- Paint priced for a partial wall when the trade practice is a full room to match
Hidden damage is a supplement, not a dispute
Water travels along framing and under cabinets, so the full scope is frequently unknown until drying is underway and materials come out. Finding more damage after the adjuster's visit is routine and expected.
Document it as you find it. Photograph the opened assembly, record the moisture readings, and have your contractor write the additional line items into a supplement referencing the original claim number.
Never sign a final release while drying is still running
Final releases close your ability to supplement. Until equipment is off, moisture readings are back to normal, and your contractor has confirmed the scope is complete, keep the claim open. If a payment arrives labeled full and final before then, ask the carrier in writing to confirm the claim remains open for supplements.
How to submit a supplement that gets approved
Supplements succeed on evidence and format. An adjuster reviewing remotely needs to see the item, the justification, and the price in a form they can compare to their own estimate.
- 1
Get a line-item comparison from your contractor
A side-by-side showing the carrier's line, your line, and the difference. Totals alone give the adjuster nothing to act on.
- 2
Attach the proof for each disputed item
Daily drying logs for equipment days, photos of the opened wall for hidden damage, moisture readings for monitoring labor.
- 3
Use industry-standard estimating
Major carriers price against standard restoration estimating software. An estimate in the same format and line-item language is far faster to approve than a handwritten quote.
- 4
Request a reinspection if the gap persists
Ask for a reinspection with your contractor present so both parties walk the same scope at the same time. Many disputes end here.
- 5
Consider appraisal for a stuck amount dispute
If coverage is agreed and only the amount is contested, your policy's appraisal clause provides a mechanism with named appraisers and an umpire. Read that paragraph before invoking it.
What not to do
Two reactions make the outcome worse. Accepting the gap and paying the difference yourself forfeits money you are likely owed. Refusing to continue drying until the estimate is fixed causes more damage, weakens your claim, and can breach your duty to mitigate.
The productive path is to keep mitigating, keep documenting, and work the supplement with paper.
Common questions
- Can my contractor talk to the adjuster directly?
- Yes, and on a technical scope dispute it is usually the fastest route. A restoration estimator and an adjuster can resolve line-item disagreements in one call that would take a homeowner several rounds. You can authorize that contact while staying copied on it.
- How many times can I supplement a claim?
- There is no fixed limit. Supplements are expected as hidden damage surfaces, and multiple ones are normal on larger losses. What matters is that each is documented and submitted while the claim is still open.
- Is a public adjuster worth it for a scope gap?
- It depends on the size of the gap. Public adjusters are licensed to represent you for a percentage of the recovery, which can make sense on a large or entrenched dispute and rarely pencils out on a small one. Get the fee structure in writing and compare it to the amount actually in dispute.
- What if the adjuster never opened the walls?
- That is common, and it is exactly why supplements exist. Have your contractor document what was found once materials came out, with photos and moisture readings, and submit it as additional scope rather than treating the first estimate as final.
