How it works

Our collision estimate and repair process

At CMD Collision in Detroit, a repair goes in six steps: a free photo ballpark price, an in-person inspection and estimate, approval, a full teardown (where hidden damage is documented and sent as a supplement), the repair itself, and pickup. You hear from us before any extra work is done.

The six steps

  1. Photo ballpark price (free). Text photos, plus your vehicle's year, make and model, to (313) 444-0236, or upload up to three photos on our quick price page. You get one ballpark starting price, not an itemized estimate.
  2. In-person inspection and estimate. Bring the car to 3843 E McNichols Rd. We inspect it and write a preliminary estimate. On insurance jobs we send it, with photos, to your adjuster.
  3. Approval. Work starts once the estimate is approved, by your insurer on a claim or by you if you're paying yourself.
  4. Teardown and hidden damage. We take the damaged area apart. If hidden damage turns up, we photograph it, send a supplement to your insurer, and contact you before doing extra work.
  5. Repair. Body work, unibody/frame straightening on our Chief frame machine where needed (we're state-certified for unibody/frame and collision-related mechanical repair), and refinishing with the Sherwin-Williams paint system. Then we reassemble the car and check the repair.
  6. Pickup. On insurance jobs you pay only your deductible, if one applies. We accept cash, credit/debit cards and Zelle. The work we perform comes with a lifetime warranty.

Why the first estimate can change

Any estimate written before the car is taken apart is based on what can be seen. Collisions often damage parts behind the bumper, fender or door, such as brackets, absorbers, sensors or structural parts. That's normal and it's why insurers allow supplements. It's also why an insurer's first estimate can differ from the final repair plan. What matters is that the extra damage is documented and approved before it's repaired.

What changes the price and the time

  • How much damage there is, and whether parts are repaired or replaced
  • Hidden damage found after teardown
  • Whether structural or frame work is needed
  • How much paint and blending is needed to match the color
  • Parts availability and insurer approval of the estimate and any supplements

Because of these, we don't promise a fixed price or turnaround before we've seen the car. Your final price comes after an in-person look.

Common questions

Why can the final repair cost be higher than the first estimate?
The first estimate is written without taking the car apart. Once the estimate is approved and the damaged parts come off, damage that was hidden behind them, such as brackets, absorbers or structural parts, can show up. We document it with photos, send a supplement to your insurer, and contact you before doing extra work.
What is a supplement?
A supplement is an addition to an approved estimate for damage found after teardown. On insurance jobs we send it to your insurer with photos for approval before that extra work is done.
How long will my repair take?
Repair time depends on the damage, so we don't promise a set turnaround. After we inspect your car in person, we'll tell you what to expect for your repair.
Do I need an appointment for an estimate?
No appointment is needed for a photo ballpark price: text photos or upload them on our website. For the in-person inspection, stop by during business hours, or call or text first.
How do I compare estimates from different shops?
Compare what each estimate covers, not just the total. Check that each one lists the same damaged parts and repairs, whether it includes paint and blending, and how the shop handles hidden damage found after teardown. Ask each shop about its warranty in writing.
