You're backing out of a tight spot off Swan Street, you cut the wheel a touch too early, and there's that sound. A scrape down the bumper from clipping the kerb, or a crack where you caught a car-park pillar. It looks bad. The first thing most people think is that the whole bumper now needs replacing.
Good news: a lot of bumpers can be repaired rather than replaced. Whether yours can comes down to a few things, and you can check some of them yourself before you even call a panel beater. At Automotive Panel Service in Richmond, plenty of the bumper repair jobs that come in looking like a write-off turn out to be a straightforward fix.
Here's how to tell the difference.
Most modern bumpers aren't metal. They're moulded plastic, usually a type called polypropylene (a flexible plastic that bends instead of denting). That one fact changes everything about how they get fixed.
A steel panel can be beaten and pulled back into shape. A plastic bumper can't. Instead, it flexes on impact, which is why a low-speed knock often leaves a scuff or a crack rather than a dent. And because it's plastic, it can be heated, reshaped, welded and refilled. So the repair path is completely different to the rest of your car's body.
If the plastic is still holding its shape, repair is usually on the table. The common cases:
Scuffs and scrapes. Surface marks from a kerb, a pillar or another car. This is paint-level damage. The area gets sanded back, filled if needed, then resprayed to match.
Shallow dents. Where the plastic has pushed in but hasn't torn. Gentle heat and reshaping can often bring it back.
Small cracks. A split in the plastic can be plastic-welded. That means melting a matching plastic rod into the crack so it fuses back into one solid piece, then sanding and repainting over the top.
Clips and tabs still intact. The bumper has small plastic tabs and brackets that hold it onto the car. If those are still good, the bumper sits back on cleanly after the repair.
Minor scuffs and small scratches are often a same-day job at APS, sometimes done in a few hours.
The honest rule of thumb: if the plastic is still holding its shape, it can usually be repaired. Once it's torn through or the mounts are broken, you're into replacement.
Sometimes a fresh bumper is the cheaper, better and safer call. The signs:
The plastic is torn or shattered. Once it's ripped right through or broken into pieces, a weld won't hold its strength the way the original did.
The mounting tabs or brackets are broken. If the bumper won't sit straight and clip on properly, it can't be lined up cleanly. Broken mounts are one of the most common reasons a bumper gets replaced.
Big sections are missing. If part of the bumper is gone, there's nothing to repair back to.
Cracks run across stress points. Several cracks, or a crack through a curved high-stress area, often won't stay fixed.
Damage runs through sensor or camera housings. When the impact has gone through the spots that hold parking sensors or a reversing camera, repair gets harder. A clean replacement is often the better option.
A long, marginal repair on a badly damaged bumper can cost more than a clean replacement and still not look right. A good panel beater will tell you that straight.

A changed quote is reasonable when the extra work is tied to a clear inspection finding. The repairer should be able to explain the link between what they found and why the repair now needs a different part, method or timeline.
| What changed | Why it matters | What the repairer should explain |
|---|---|---|
| Hidden bumper bracket | The bumper may not sit straight without it | Which bracket is broken and whether it can be repaired or replaced |
| Broken clips | The panel or trim may not refit securely | Which clips are missing, snapped or weakened |
| Sensor issue | Parking, radar or camera systems may be affected | Whether the mount, wiring or sensor position needs checking |
| Paint blending required | One panel may not match cleanly on its own | Why the colour or finish needs blending into a nearby panel |
| Old repair found | New damage may sit over filler or old paint | How the old repair changes preparation or durability |
| Corrosion found | Paint may not hold properly over rust | What needs cleaning, treating or replacing |
| Insurer scope change | Insurance work must match the approved repair method | What has been sent to the insurer and what is waiting on approval |
A changed quote is harder to assess if the explanation is vague. "It needs more work" is not enough. You should know what was found and why it changes the job.
Price depends on the damage, your paint colour and your car, so treat these as a rough guide, not a quote:
Metallic and pearl colours cost a bit more to blend than plain white or black. The only way to get an exact figure is a photo or a quick look in person.
Many bumpers house parking sensors or a reversing camera. If the damage is near them, it can change the repair-or-replace call, and the system may need recalibrating afterwards so it reads distances correctly. (More on that in our separate guide to sensor and camera recalibration.)
For minor bumper damage, check the repair cost against your excess first. If a scuff repair costs less than what you'd pay in excess, paying directly is often the smarter move. Your insurer's Product Disclosure Statement (the document that sets out what your policy covers) is the one to go by, so read it or call them before you decide. We cover this in more detail in our guide on whether to claim for a minor scratch or dent.
That scrape from the Swan Street car park is probably less serious than it looks. If the plastic is still in shape, it's likely a repair. If it's torn or the mounts are gone, a replacement may be the better call. The honest answer depends on seeing the damage.
