What to Do When Contractor and Adjuster Estimates Disagree

A gap between your contractor's repair estimate and the adjuster's scope of loss is one of the most common friction points in homeowners insurance claims. It's also one of the most resolvable — when you approach it correctly.

The key insight: the source of the gap determines how to address it. Treating all gaps the same way produces inconsistent results. Identifying the specific type of gap and addressing it with the right documentation produces specific, documentable objections that move claims forward.

What Are the Four Types of Gaps?

Scope gaps — items your contractor includes that the adjuster doesn't. The adjuster may have missed damage, applied a narrower standard for what's necessary, or excluded items based on a coverage determination. These are the most common gaps and the most addressable with documentation.

Quantity discrepancies. Your contractor measured 1,600 square feet of affected flooring; the adjuster shows 1,100. A 500-square-foot gap in a measurement isn't a pricing disagreement — it's a factual error that understates every line item in that area. Resolvable with your contractor's written measurements.

Unit pricing gaps. Your contractor prices at current local market rates; the adjuster uses Xactimate regional database pricing, which often lags local market conditions — particularly after high-demand weather events when labor costs spike. A consistent 20-30% gap between Xactimate pricing and your local contractor rates is documentable.

Coverage disagreements. The adjuster excluded specific items based on a policy interpretation — a code upgrade they claim isn't covered, a matching requirement they dispute, an exclusion they've applied. These require a coverage analysis and written dispute, not just documentation of damage.

How Do You Document the Gap?

Lay both documents side by side and identify specifically, line by line:

• Items in the contractor's estimate absent from the adjuster's scope
• Items where quantities differ — note the specific measurement for each
• Items where unit pricing differs significantly — note both prices for each item

Document this comparison in writing before doing anything else. "The adjuster's estimate omits subfloor replacement (lines 24-26 of contractor estimate); the adjuster's quantity for flooring is 1,100 SF vs. our contractor's measured 1,600 SF" is actionable. "The estimate seems low" is not.

How Do You Get Usable Justification From Your Contractor?

For every scope gap, ask your contractor for written technical justification — not just an assertion that the work is needed, but a specific explanation of why it's necessary and how it connects to the covered loss.

Useful: "The subfloor shows moisture saturation at 18% — above the 16% threshold for remediation — consistent with the water intrusion event on [date]. Replacement is required before new flooring can be installed to prevent ongoing structural degradation."

Not useful: "We think the subfloor needs to be replaced."

The insurer will evaluate your supplement based on the quality of the technical justification. Make sure your contractor provides documentation that can stand on its own.

How Do You Submit a Formal Supplement?

Submit in writing with documentation organized by the specific gap type:

• Each disputed item identified by description and estimate line reference
• Your contractor's written technical justification for each scope gap
• Supporting photos of the damage cited in each justification
• Your contractor's measurement documentation for quantity disputes
• Current market pricing documentation for pricing disputes
• Policy language supporting your position for coverage disputes

Request a written response within 10-15 business days. Keep a log of all supplement-related communications.

Should You Hold Repairs on Disputed Items?

On undisputed items, proceed with repairs — don't delay your entire project for a disputed line item. On disputed items, hold permanent repairs until the supplement is resolved or you have written authorization to proceed. Once damage is repaired, the physical evidence for the supplement is gone.

If the disputed items are blocking progress on the overall project, document them thoroughly, proceed with surrounding work, and maintain clear photographic evidence of the undisturbed disputed areas.

When Does the Appraisal Process Apply?

If the gap is primarily about value — pricing and quantities with coverage acknowledged — and informal supplement resolution isn't producing movement, the formal appraisal process provides a binding structured path. Check your policy's Conditions section for the appraisal provision and any deadline to invoke it.

Frequently Asked Questions

How long does a supplement review typically take? Most insurers process supplement requests within 2-4 weeks when documentation is complete. Complex supplements or those requiring re-inspection can take 4-8 weeks. If you don't receive a written response within 15 business days of a complete submission, follow up in writing.

What if my contractor's estimate is significantly higher than the adjuster's for every line item? A consistent pricing gap across all items typically indicates a local market pricing difference rather than scope disagreement. Document current local market rates — quotes from multiple licensed local contractors — and submit the pricing evidence with a written request for Xactimate pricing to be updated to reflect your market.

Can I use my contractor's estimate as the sole basis for a supplement? The contractor's estimate is your evidence, but the supplement request needs to explain why each item is necessary and how it connects to the covered loss. The estimate alone isn't sufficient — the written justification from your contractor explaining each item is what gives the supplement its basis.

What if the adjuster excludes an item based on a policy provision I think is wrong? That's a coverage dispute, not a scope or pricing dispute. Respond in writing citing the specific policy language you believe supports coverage. Attach documentation. If unresolved, escalate to a supervisor and consider a public adjuster or attorney for significant amounts.

Should I get more than one contractor estimate to support a supplement? Multiple contractor estimates are significantly stronger than one — they establish a consensus view that's harder to dismiss. If two independent contractors both include a line item the adjuster's scope omits, that consistency is compelling evidence.

Estimate Dispute Checklist

• Identify each gap by type: scope, quantity, pricing, or coverage — each needs a different approach
• Lay both estimates side by side and document each gap specifically in writing
• Get written technical justification from your contractor for every scope gap — specific, not general
• Submit a formal supplement organized by gap type with documentation attached
• Request written response within 10-15 business days
• Hold permanent repairs on disputed items — preserve the physical evidence
• Consider the appraisal process for persistent value disputes with acknowledged coverage
