When a wildfire reduces a home to its slab, or a tornado scatters framing lumber across a quarter-mile debris field, policyholders expect a settlement that reflects the true cost of rebuilding. What they receive instead, with startling regularity, is a line-item estimate generated by Xactimate that bears little resemblance to the actual scope or cost of reconstruction.
As public adjusters, we occupy the gap between the policyholder’s reasonable expectations and the carrier’s valuation methodology. In that gap, one truth has become impossible to ignore: Xactimate, the insurance industry’s dominant estimating platform, was never designed to quantify total-loss structures. Carriers deploy it for precisely that purpose, producing estimates that systematically undervalue the most devastating claims a homeowner will ever file.
What Xactimate Is — and What It Was Designed to Do
Xactimate, developed by Verisk Analytics through its Xactware subsidiary, uses a database of localized material and labor costs to generate repair estimates. An adjuster surveys damage, selects line items from a categorized price list, inputs quantities, and the software calculates a total. For a hail-damaged roof, a section of wind-damaged siding, or a kitchen fire confined to one room, the platform performs well. It provides a standardized framework that allows adjusters across the country to speak a common estimating language.
The trouble begins when that framework is asked to do something fundamentally different: price the complete demolition and reconstruction of an entire structure from the ground up. A total loss is not a repair. It is a fully involved construction project. That is exactly where Xactimate’s architecture breaks down.
It is worth remembering what came before. Prior to Xactimate’s adoption, carrier adjusters would inspect a loss alongside a real contractor. The adjuster understood construction because the job required it. Today, adjusters are trained on the software instead of construction fundamentals. The program has replaced the knowledge it was supposed to supplement.
The Concrete Problem
Xactimate’s concrete line items are structured around repair scenarios — patching a slab section, pouring a small pad, replacing a segment of stem wall. The pricing reflects small-quantity pours, limited forming, and the assumption that existing infrastructure surrounds the work area on flat ground under easy conditions.
A total-loss rebuild demands an entirely different scope of work: engineered drawings, soil testing, excavation, grading, compaction, full formwork, continuous rebar placement, anchor bolt installation, and large-volume pours coordinated with pump trucks and finishing crews. The logistics of a full foundation pour have nothing in common with the patch-and-repair scenarios the software is built around. When a carrier adjuster selects Xactimate’s concrete line items and multiplies by square footage or cubic yards, the result can fall thirty to fifty percent below what a licensed general contractor would actually bid.
Framing: Line Items Versus Engineering Reality
A total loss is not a repair. It is a fully involved construction project. That is exactly where Xactimate’s architecture breaks down.
A complete wood-frame structure is an integrated system: engineered trusses specified to local load requirements, headers sized to span calculations, shear walls with specific nailing patterns, hold-down hardware, and engineered connections at every load-bearing junction — all coordinated according to a stamped structural plan. None of this is captured by selecting per-foot wall framing from a dropdown menu.
Current code requirements sharpen the problem. A home destroyed in 2024 that was built in 1985 must be rebuilt to 2024 standards, which may require hurricane strapping, seismic reinforcement, upgraded shear panels, and energy-code-compliant framing techniques. Xactimate’s line items do not differentiate between building to legacy code and building to current code. A wall is a wall, regardless of the engineering behind it.
Windows: The Specification Gap
Xactimate’s window pricing is basic. In a total-loss reconstruction, every window is a new-construction installation — each rough opening framed, flashed, and integrated into the weather-resistive barrier from scratch. Current energy and safety codes in most jurisdictions now require performance-rated glazing that costs significantly more than the builder-grade units Xactimate defaults to. When a carrier’s estimate arrives with pricing that would barely cover replacement-grade vinyl, and the rebuild requires code-compliant products installed in new-construction conditions, the gap is not a rounding error. It is tens of thousands of dollars per home, sometimes more.
The Custom Home Bottleneck
There is a further reality that Xactimate’s pricing methodology ignores entirely, and it may be the most consequential factor in catastrophe-affected areas: the homes that are destroyed are often custom-built, and the contractors capable of rebuilding them to like kind and quality are a limited and highly sought-after resource.
Production builders who frame tract homes at volume pricing do not build custom residences. The builders who do operate at a different price point and with limited capacity. When a catastrophic event destroys dozens or hundreds of custom homes simultaneously, those builders become an impassable bottleneck. Demand surges. Lead times extend. Xactimate’s database does not account for this. It prices labor and materials as though a general contractor is available at regional average rates on a normal Tuesday. In a post-disaster market where custom-home builders are booked eighteen to twenty-four months out and bidding accordingly, the software’s pricing is fictional.
A $1.4 Million Gap: One Family’s Total-Loss Claim
We see this play out in real files. We recently represented a policyholder with a total-loss claim. The carrier provided an Xactimate estimate that landed right at the policy’s base dwelling limit of $1.4 million and refused to adjust further. Their position was that additional funds would only be considered if and when actual building costs exceeded that figure — meaning the homeowner would have to start construction, spend their own money, and hope the carrier eventually made up the difference.
We took a different position. The carrier had a duty to investigate the full extent of the loss, not to defer that obligation to the construction phase. We provided detailed estimates to rebuild the home and separate estimates to bring the structure into compliance with current code standards — two distinct scopes of work that the policy’s dwelling coverage and code-upgrade provisions were designed to address.
After extended negotiation, the dwelling value on the claim was increased from $1.4 million to $2.8 million. The carrier ultimately acknowledged that its Xactimate-based estimate was less than half of what it would actually cost a real contractor to rebuild the home. The gap — one hundred percent of the carrier’s original figure — existed from the moment they issued their initial valuation. The only question was whether anyone would insist on closing it.
Even the Carriers Know
The pricing gap becomes impossible to defend when the carriers themselves cannot explain it. In our experience with large-carrier catastrophe claims, when we present a concrete subcontractor’s bid, a framing contractor’s bid, or a window vendor’s bid alongside the corresponding Xactimate line items, the adjusters resist at first. They push back. They cite the database. Then they fold. They override their own Xactimate line items with the vendor’s actual pricing, because they have no basis to dispute a licensed contractor’s documented bid. The software says one thing, the contractor says another, and when pressed, the adjuster has no legs to stand on.
This is a telling admission. When a carrier’s own field adjusters cannot defend the software’s output against a straightforward contractor bid on the three most expensive components of a rebuild, the software is not functioning as an estimating authority. It is functioning as a starting position — one that favors the carrier until someone pushes back, and one that an unrepresented policyholder may never think to question.
“Never Customize Without Approval”
If Xactimate’s technical limitations were the only issue, the problem might be manageable. The deeper problem is cultural rather than technical. Carrier-employed and carrier-contracted adjusters are routinely instructed — through training programs, desk review protocols, and internal guidelines — never to customize line items or deviate from the standard price list without explicit supervisory approval. The message is consistent across the industry: write to the database. If the line item does not exist, it does not go in the estimate. If the price seems low, the database is the authority.
The paradox is plain. Xactimate’s own publisher acknowledges that its database represents regional averages for standard repair scenarios and that professional judgment should inform every estimate. The carriers who license the software have done the opposite — building compliance cultures that treat the database as a ceiling rather than a floor and that discipline adjusters who exercise the very judgment the tool was designed to accommodate.
A Fine Tool Misapplied
None of this is to say Xactimate is a bad product. For the bread-and-butter claims that constitute the majority of property adjusting — roof repairs, water damage, partial fire losses — it is a capable, useful platform. The problem is not what the tool is. The problem is what the carriers use it for. Repair-estimating software has no business pricing a complete reconstruction. When the result is handed to a grieving policyholder as the carrier’s determination of what they are owed, the carrier is not using Xactimate as a guide. It is using Xactimate as a shield — a way to present an inadequate number with the appearance of precision.
The estimate looks thorough. It runs to dozens of pages with hundreds of line items carried to the penny. It looks like science. It is a repair estimate dressed up as a construction bid, and the difference can amount to hundreds of thousands of dollars. The measure of an estimating platform is not how efficiently it processes routine claims. It is whether it gets it right when a family has lost everything. By that measure, Xactimate has work to do.
