Should I Get a Repair Estimate Before Filing a Claim
No, you don't need your own estimate first, but knowing roughly what repairs cost protects you when the adjuster's number is low.
The claim process generates the other insurer's estimate for you
When you file a third-party claim, the at-fault driver's insurer is supposed to arrange an inspection and produce an estimate themselves. That's part of what the claim does. You don't have to pay for one upfront just to get the process started, because the obligation to assess the damage and pay for it sits with them.
Where getting your own number helps is afterward, once you have something to compare against. Insurers sometimes write estimates using lower-cost parts, fewer labor hours, or a shop they prefer that happens to be cheaper. If you have no reference point, you have no way to tell whether that number is fair or short. A second estimate from a shop you trust, gotten after their adjuster's number comes in, gives you leverage without costing you anything before you need it.
There are cases where getting ahead of it makes sense. If the damage looks like it might total the car, or if you suspect the adjuster is going to lowball you based on how the call went, a quick estimate from your own shop can speed things up or give you something to push back with right away. It also matters if you're using your own collision coverage instead of waiting on the other insurer, since your insurer will want its own number regardless.
What varies is how each insurer's process actually works. Some send their own adjuster to inspect the car, some ask you to use a direct repair shop, some accept photos and let you choose. Ask early what their process is so you know whether getting your own estimate adds value or just duplicates work they're already going to do.
What to do about estimates during a third-party claim
- Let their process start first Give the at-fault insurer a chance to inspect the car and write their estimate before spending money on your own. It's their responsibility, not yours.
- Get a second opinion if low If their estimate seems thin compared to what you know repairs usually run, take the car to a shop you trust for a comparison number. Use it to push back specifically.
- Keep every written estimate Save copies of any estimate, whether from them or a shop you visited. These become your evidence if the number gets disputed later.
- Ask who controls the shop Some insurers steer you toward a preferred shop with a lower estimate attached. You can usually choose your own shop instead, so ask before agreeing to anything.
- Skip verbal numbers Wait for a written estimate before any shop starts work. A verbal figure can change once the adjuster sees the car in person.
A case where the second estimate paid off
A driver was rear-ended at a stoplight and filed a claim against the other driver's insurer. The adjuster sent a written estimate that covered the bumper and taillight but left out a crack in the trunk alignment that the driver had noticed right after the crash. The number looked reasonable at first glance, so the driver almost signed off on it.
Instead, they took the car to their regular mechanic for a second look before agreeing to anything. The mechanic pointed out the alignment issue and wrote up a separate estimate that included it. The driver sent both estimates back to the adjuster, pointing out the gap, and the adjuster revised the payout to cover the additional repair. The whole exchange added a short delay but caught damage that would have otherwise come out of the driver's pocket.
Once repairs are settled fairly, compare quotes to make sure your own coverage is priced right.
What if the adjuster's estimate and my mechanic's estimate don't match?
Send both to the adjuster in writing and ask them to explain the difference. Mismatches usually come down to parts choices, labor rates, or something one estimate missed entirely, like hidden frame or alignment damage that only shows up once a shop has the car on a lift.
You don't have to accept the lower number just because the insurer wrote it. Point out specifically what your estimate includes that theirs doesn't, and ask for a supplement if new damage turns up once repairs are underway. If the gap is large and they won't budge, you can ask for a second inspection or involve your state's insurance department, since how disputes get escalated varies by state and by insurer.
The first estimate you see isn't final. Treat it as an opening number, not the last word.
Can I choose my own repair shop instead of the insurer's recommended one?
Yes, in most cases you can choose your own shop, though the insurer's preferred shop may come with a guarantee or faster approval. Ask whether using an outside shop changes how payment or warranty coverage works before you decide.
Who pays for a rental car while my car is being repaired?
The at-fault driver's insurer should cover a rental while repairs happen, but approval and the type of vehicle can take time or get capped. Ask upfront what's covered and for how long, since this varies by insurer and sometimes by state rules.
What happens if the other insurer disputes who was at fault?
If fault is disputed, your repair claim can stall until liability is sorted out, so it may be faster to use your own collision coverage and let your insurer pursue reimbursement later. Check your policy for how that process works before deciding.
