Quick Answer On a covered claim: the carrier does — and the fear that it lands on you is the single most repair-delaying myth we meet. When teardown finds damage the first estimate couldn’t see, the shop documents it with photographs and files a supplement; the carrier reviews and pays it on top of the original estimate. Your share doesn’t grow: the deductible counts once per claim, no matter how many supplements the repair needs. The honest exceptions are narrow and always on paper: betterment lines (wear billed to you when a worn part is replaced new) and work you chose outside the claim’s scope — both of which you approve in writing before they exist. “Found more damage” is the system working, not your wallet opening.

Nothing did: a first estimate prices what was visible the day it was written — frequently from photos, always with panels still bolted on — and crash energy does its expensive work behind what’s visible: absorbers crushed under intact covers, brackets cracked behind clean fenders, rails nudged under straight-looking panels. Teardown is the first honest look, which is why [first estimates run short routinely](https://dgcollision.com/guides/insurance-estimate-final/) and why in our published claim files, supplements aren’t the exception — on collision work they’re closer to the rule. The system was built for this: document the find, photograph it, file the supplement, carrier reviews, carrier pays — the same claim, the same deductible already counted, new money from their side of the table. Your share is a fixed number, not a percentage of surprises. The deductible subtracts once per claim — [once, full stop](https://dgcollision.com/answers/how-many-times-do-i-pay-my-deductible/) — and supplements never restart it. What makes supplements move fast is the shop’s paperwork discipline: a find described in adjectives gets argued; a find photographed at teardown with part numbers gets paid. That’s the half of this business nobody sees — and it’s also why [hosting the adjuster inspection at the shop](https://dgcollision.com/answers/should-the-adjuster-inspect-my-car-at-the-body-shop/) shrinks the whole question: an estimate that starts closer to reality needs fewer supplements, and Texas’s §542 claim-handling clocks keep the carrier’s review on a schedule documentation makes enforceable. If a shop ever tells you mid-repair that you owe thousands for “what we found,” on a covered claim, the correct response is a question: “has the supplement been filed with the carrier?” — because that sentence usually means someone skipped the paperwork, not that you owe the money. Now the two honest exceptions, so this page can’t be accused of selling a fantasy. Betterment: when the crash forces replacement of something half-worn — a tire, a battery — some carriers bill you the used-up portion, a legal and contestable line that [the short-check answer](https://dgcollision.com/answers/why-is-my-insurance-check-less-than-the-estimate/) decodes line by line; we flag every betterment line before it surprises anyone. Chosen scope: if you add work the claim doesn’t owe — fix the old door ding while the bumper’s being painted, upgrade a part beyond the claim — that’s your line, priced from [published rates](https://dgcollision.com/pricing/) and approved by you in writing before a tool touches it. That’s the whole list. Everything else — hidden structure, extra parts, more paint hours, calibration the teardown revealed — is carrier money on a documented claim, and your out-of-pocket stays what it was quoted: typically the deductible, once, at pickup, with the first $1,000 covered on qualifying hail repairs. Related Questions ## ASKED ALONGSIDE THIS ONE The shop found more damage. Do I have to approve the supplement? + A: You approve the repair plan; the carrier approves the money — and for claim-covered damage, “approving” costs you nothing but a signature. The find is photographed, filed, and funded on the carrier’s side. Where your judgment genuinely matters is optional scope: repairs the claim doesn’t owe are your call and your line item, decided before work, never after. Can the insurance company refuse a supplement? + A: They can question one — and documentation is what ends the questioning: teardown photos, part numbers, and procedure citations get paid; vague line items get negotiated. In our published claim files the pattern holds across carriers: documented supplements close. A refusal that survives real evidence is rare, appealable, and — on amount-of-loss disputes under newer policies — subject to the appraisal rights Texas added in 2026. Does a supplement delay my repair? + A: The review takes the time it takes — that’s carrier time, bounded by §542’s clocks — but the work rarely stands still: parts already approved keep moving, and the loaner means the wait costs you convenience, not mobility. The real schedule killer isn’t supplements; it’s estimates that started so far from reality that the claim needs three rounds of them — which is the argument for the inspection happening here in the first place. What if I’m paying cash and the repair uncovers more? + A: Then you’re the carrier — so you get the carrier’s courtesy: the moment teardown finds something beyond the written estimate, work pauses and you get the find, the photo, and the price before anything is repaired. No surprise invoices, ever — a cash job’s final number should differ from its estimate only by decisions you made with the evidence in front of you.
