Bumper Repair and Replacement
In short: A bumper on a commercial truck or a motorhome is frequently a structural mounting point for a hitch, a lift gate or a tow rating, which is why replacing one is rarely just a cosmetic decision.

Bumpers get treated as cosmetic parts. On the vehicles we work on they usually are not, because a bumper on a motorhome or a commercial truck is frequently doing structural work: carrying a tow rating, mounting a lift gate, providing recovery points, or acting as the rear impact structure a regulation requires.
That changes the repair decision. A cosmetic bumper can be made to look right. A structural bumper has to be made to work right, and those are different standards.
What we work on
Thermoplastic covers. Vans, light trucks, some Class C and Class B front and rear. Repairable by plastic welding and rear reinforcement in most cases.
Steel bumpers. Commercial trucks, older coaches, bus conversions. Repairable by straightening and welding, or replaceable, or fabricable.
Aluminium. Some coaches and trailers. Weldable but requires the right process and filler for the alloy.
Fiberglass valances and caps that incorporate the bumper. Common on Class A. These are body panels rather than bumpers and are handled as fiberglass repair.
Structural bumpers with integrated hitch receivers. Motorhome rear bumpers with tow ratings, commercial rear bumpers, and anything a lift gate mounts to.
The structural question
The first thing we establish is what the bumper is doing.
If it is carrying a tow rating, the repair has to restore that rating. That means structural welding to standard, verification that the mounting points are square and sound, and inspection of the frame horns behind. In some cases the honest answer is that a repaired assembly cannot be certified to its original rating and replacement is required. Making a rated component look correct while leaving its rating unverified is how a hitch fails while towing.
If a lift gate mounts to it, the same applies with more force, because a lift gate applies a large cantilever load repeatedly.
If it is genuinely cosmetic, we can be much more relaxed about method and much more focused on finish.
What is behind the bumper
A bumper absorbs energy and passes the rest into the structure. So we inspect behind every one we remove, and it is common to find:
- Bent or torn mounting brackets
- A deformed crash bar or absorber
- Cracked or deflected frame horns
- Shifted frame rails, which is a frame straightening job rather than a bumper job
- Damaged wiring, sensors and reverse cameras routed through the bumper area
- On modern vehicles, misaligned parking sensors and radar units that need ADAS recalibration
Fitting a new bumper over bent brackets produces a bumper that sits wrong and will not sit right no matter how many times it is adjusted.
Repair, replace or fabricate
Repair where the material is sound and the geometry is recoverable. Plastic welding with rear reinforcement on covers, straightening and welding on steel.
Replace where a part is available and repair is uneconomic or the rating cannot be restored.
Fabricate where the part is discontinued, which on coaches over ten years old and on bus conversions is the common case. Fabrication also allows integration: a receiver, recovery points, lighting, a tire carrier or a step built into one structure rather than accumulated as bolt-ons. That is covered further under custom fabrication and storage racks and bumpers.
What it costs
| Job | Typical range | Hours |
|---|---|---|
| Plastic cover repair and refinish | $500 to $1,400 | 3 to 8 |
| Bumper replacement, van or light truck | $1,200 to $3,500 | 6 to 16 |
| Steel bumper straightening and refinish | $1,400 to $3,000 | 8 to 16 |
| Heavy-duty or structural commercial bumper | $2,500 to $6,000 | 12 to 28 |
| Custom fabricated bumper | $3,500 to $8,500 | 18 to 40 |
Body labor is $210 per hour, mechanical and structural $260. Parts over $100 carry 35 percent markup. See the pricing page.
Fleet considerations
Bumper damage is the most common single item on a delivery or service fleet, because low-speed contact in loading areas is a daily hazard. For fleet operators the useful approach is standardisation: a fabricated steel bumper on a delivery van costs more once and then stops costing anything, where a plastic cover is a recurring line item.
We do that work as a programme, scheduling vehicles so the operator is never short more than an agreed number at a time. Fleet operators covers how we handle multi-unit accounts.
Estimates are $150 and credited back against an authorized repair.
