Quick Answer Judge it by evidence, not by a clean-looking panel. A repair done right leaves a paper trail: a post-repair scan with codes cleared, a printed calibration report for any disturbed sensor (calibration runs $350–$450 per operation), paint matched across more than one light source, and panel gaps even and consistent down the car. Then the test drive — no pull, no new noise, no warning light. And behind all of it, a written warranty you can hold: ours is lifetime except mechanical. If another shop’s work has you worried, bring it in — we inspect and document what’s actually there, no charge for the look.

What decides whether a repair was done right is mostly invisible from the driver’s seat, which is why the honest answer to “how do I know” is: ask for the evidence. Start with the scan. A proper repair includes a pre-repair scan to find fault codes and a post-repair scan showing those codes diagnosed and cleared — printed, with your car’s VIN on it. If the hit touched a camera, radar, or parking sensor, there’s a separate [calibration](https://dgcollision.com/answers/is-adas-calibration-necessary/) step with its own printed report, because a sensor that’s a fraction of a degree off misses by feet at distance and fails silently; through our calibration specialists that runs $350–$450 per operation, and the report is the proof it was actually done. Then the parts you can check, if you know where to look. Paint: a real match is read across more than one light — daylight, shade, indoors — because a blend that looks perfect under the shop lights can mismatch in the sun; done right, the repair disappears at every angle, and fading stays covered under the warranty rather than showing up in a year. Fit: the [panel gaps](https://dgcollision.com/answers/uneven-panel-gaps-after-collision/) are the factory’s own straightness gauge — they should be even and consistent from one side of the car to the other, doors and hood and trunk closing with the same effort they did before. A tapered gap or a door that needs a shove is the structure telling on a shortcut. And the test drive: no pull to one side, no new vibration, no warning light that wasn’t there before. Behind every one of those checks is the thing that makes them enforceable — the [written warranty](https://dgcollision.com/answers/do-body-shops-guarantee-their-work/). No Texas law requires a shop to warranty its work, so the guarantee is only as good as what’s printed and who stands behind it; ours is lifetime on the repair except mechanical (1 year / 10,000 miles there), and the full terms are public on our [terms page](https://dgcollision.com/terms/), not recited at pickup. If you’re reading this because a repair already feels off — a color that’s close-but-not-right, a gap that bugs you, a light that came back — that’s worth a second look, and it’s exactly the kind of car another shop might wave off. We don’t: we inspect it, scan it, and document what’s actually there, so you have the facts whether the fix was ours or someone else’s. (That’s the same reason we take on the cars [other shops turn away](https://dgcollision.com/answers/shop-wont-work-on-my-car/).) Related Questions ## ASKED ALONGSIDE THIS ONE What paperwork should I get at pickup? + A: The final repair invoice itemizing what was done, the post-repair scan result, a calibration report for any sensor that was disturbed, and the written warranty with its scope and duration stated plainly. If sensor work was involved and there’s no calibration printout, ask — that document is the only proof the step happened, and it fails invisibly when it’s skipped. How can I tell if the paint was matched properly? + A: Look at the repaired panel next to the ones beside it in three lights — direct sun, open shade, and indoors — from a few angles. A proper blend disappears in all of them; a shortcut shows as a halo or a slightly-off shade in one light even when it hides in another. Metallics and tri-coats are the hardest, which is why they’re blended into neighboring panels rather than hard-edged at a seam. A warning light came back on a few days after I got it back. Normal? + A: No — take it back in. A light that returns after a repair usually means a sensor wasn’t calibrated, a connector wasn’t fully seated, or a fault wasn’t cleared. It’s a scan-and-diagnose visit, and under a real warranty it’s covered. The scan reads whether the issue is related to the repair; don’t let it ride, especially on airbag or ADAS lights. Can you check work another shop did? + A: Yes — a second look is free, and we document what we find: scan results, calibration status, paint and panel-fit observations, in writing. If it’s solid, we’ll tell you that too. If it isn’t, you’ll have the evidence to take back to the first shop or your insurer. Either way you leave knowing, instead of wondering.
