What sets the price
Four things, in the order they matter.
- Whether the cover can be repaired at all.
Plastic bumper covers with scuffs, small cracks or holes can often be plastic-welded, filled and refinished. That keeps the original part on the car and costs a fraction of a replacement. It’s the cheaper road by a wide margin. If the mounting tabs are broken, or the reinforcement bar behind the cover is bent, replacement is the safer call. - How far the paint has to blend.
A bumper is rarely painted on its own. The color is matched to your vehicle’s paint code and then blended into the panels either side, or you get a visible line where the repair stops. Blending costs more than painting one part. It’s the difference between a repair you can see and one you can’t. - The sensors behind it.
Parking sensors, blind-spot radar and forward cameras all sit in or behind bumper covers now. They’re removed and refitted or replaced outright, and then they have to be re-aimed. On a lot of cars that single factor costs more than the bumper itself. - The badge on the car.
Parts prices for a European or luxury vehicle are higher, and some designs need more disassembly to reach the same damage. Two cars with identical dents can be quoted hundreds apart for reasons that aren’t about the dent at all.
What the data says
On a modern car, the sensors are most of the bill.
AAA put numbers to this in a study released on 14 December 2023. Across the vehicles it examined, advanced driver-assistance systems added up to 37.6% to the total repair cost after a crash. Not the bodywork. The electronics.
- Rear
“The average cost of replacing ADAS components in a minor rear collision repair was $684, or 40.9% of the average total repair estimate of $1,698.” A minor rear collision is, in practice, usually a bumper job. - Front
“The average cost of replacing ADAS components in a minor front collision repair was $1,540, or 13.2% of the average total repair.” - Mirror
Not a bumper, but it makes the point better than either: on a side mirror repair, “an average of 70.8% of the repair cost ($1,067) was attributable to the ADAS camera included in the side mirror assembly.”
Those are national averages from one study rather than a quote for your car. Your car isn’t the average. A bumper on a 2012 sedan and a bumper on a 2022 crossover are different jobs that happen to share a name, and the gap between them is mostly electronics.
Repair or replace
What decides which one you’re paying for.
- Repairable
Scuffs, scrapes, small cracks and holes in a plastic cover, where the mounting points are still sound. The cover is welded, filled and refinished, and the original part stays on the car. - Replace
Broken mounting tabs, a torn or shattered cover, damage to the reinforcement bar behind it, or a cover already repaired once in the same spot. There is no shortcut past any of those. - Either way
If a sensor or camera sits in the damaged area, it gets checked and re-aimed whichever route the cover takes. That step isn’t optional. It’s also not in any body-shop price you found online. How that re-aiming is done, and who should do it, is in our ADAS calibration guide.
What your estimate has to tell you
Three of these are on the shop, whoever you pick. That’s not our policy. It’s state law.
- Over $100, it has to be in writing.
RCW 46.71.015 requires that “all estimates that exceed one hundred dollars shall be in writing.” A verbal number for a bumper isn’t an estimate. - The invoice has to name the type of part.
RCW 46.71.015(2) requires an invoice to carry “an indication whether the parts supplied are rebuilt, or used, if applicable or where collision repair is involved, aftermarket body parts or nonoriginal equipment manufacturer body parts, if applicable.” A bumper cover is an exterior body panel, so it’s this one that covers you. - The bill cannot drift past 110%.
RCW 46.71.025: “The repair facility may not charge the customer more than one hundred ten percent, exclusive of retail sales tax, of the total shown on the written price estimate” — not without asking you first. If more damage turns up once the cover is off, the shop has to come back to you before it spends your money. That’s the whole point of the rule.
You can also keep the old part. RCW 46.71.021 requires a shop to return replaced parts to you when the work is finished, as long as you asked for them at the time you authorized the repair.
