Bumper damage ranges from a light parking scuff to a cracked or split panel, and most of it can be repaired rather than replaced. We assess the type and extent of damage first, then repair using the method that gives the best long-term result rather than defaulting to a full replacement.
Bumpers take more knocks than any other panel on the car, mostly from low-speed contact — kerbs, parking bollards, other vehicles in tight car parks. The damage varies a lot in severity, from a surface scuff that has only marked the paint, through to a crack in the plastic. It can also mean a split at a mounting point, or distortion where the bumper has been pushed out of shape by an impact. Each type of damage calls for a different repair approach, so the first job is establishing exactly what we're dealing with.
Scuffs and light scratches that haven't gone through to the plastic beneath the paint are often addressed with careful preparation, filling where needed, and refinishing rather than any structural repair to the bumper itself. Cracks and splits are a different matter — these usually need the plastic itself repaired, using plastic welding or specialist repair techniques suited to the specific bumper material, before the surface can be refinished. Distortion, where the bumper has been pushed out of its original shape, sometimes responds to careful reshaping, but where the plastic has been overstressed, replacement may be the safer route.
Modern bumpers are rarely just a plastic shell. Many carry parking sensors, and increasingly they house radar units that support ADAS features like adaptive cruise control or automatic emergency braking. Where a bumper has to come off for repair or is being replaced, these components need to be removed and refitted. In the case of radar-linked systems, they also need to be checked and recalibrated correctly so they continue to function as intended.
Deciding between repairing the existing bumper and fitting a replacement comes down to a few things: how extensive the crack or split is. It also depends on whether the plastic has been stretched or thinned beyond a safe repair, and whether sensor or radar mountings have been damaged. Finally, it depends on how the repaired bumper is likely to hold up over time compared with a new one. We explain this assessment plainly rather than defaulting to whichever option is more profitable for us.
How it works
Inspection
The bumper is inspected to identify the type of damage present and check for any affected sensors, radar units or mounting points.
Repair or replace decision
Based on the extent of the damage and the condition of the plastic, we confirm whether repair or replacement is the appropriate route.
Plastic repair or replacement
Cracks and splits are repaired using appropriate plastic repair techniques, or the bumper is replaced where repair isn't viable.
Sensor and radar handling
Parking sensors and radar units are removed and refitted correctly, with recalibration carried out where the system requires it.
Refinishing
The repaired or new bumper is prepared and painted using in-house mixed colour, either as a local blend or a full refinish depending on what gives the best match.
Final check
Fit, finish and the operation of any sensors or radar-linked systems are checked before the vehicle is handed back.
Capability
Bumpers are typically moulded from a flexible plastic designed to absorb minor impacts without transmitting force to the vehicle's structure. This flexibility is also what makes them repairable in many cases — plastic welding and specialist filler systems can restore a cracked or split area to a stable, paintable surface. This applies provided the damage hasn't stretched or thinned the material beyond safe limits. Where that limit has been passed, no repair technique will hold reliably, and replacement becomes the sensible option.
Parking sensors sit in housings within the bumper and rely on a clear, correctly seated mounting to work accurately. If a sensor's housing is cracked or the sensor itself has been knocked out of position, it can give false readings or stop working altogether. This is why we check sensor function as a specific step rather than assuming refitting alone resolves it. Radar units, used for features like adaptive cruise control, are more sensitive still — they need to be aimed precisely, and any repair or replacement affecting their mounting typically requires recalibration using appropriate equipment.
Colour matching a repaired or replacement bumper to the rest of the car is partly a science and partly a judgement call. We mix paint in-house to the vehicle's factory code, but even an exact code match can look slightly different under certain lighting if only a small area is refinished, particularly on metallic or pearlescent colours. This is why we sometimes recommend refinishing the whole bumper, blending into the wings, rather than just the repaired section — it gives a more even, less visible result overall.
What affects the cost of a bumper repair includes whether the damage is repairable or requires replacement, and how many sensors or radar components are involved. It also depends on whether recalibration is needed, and whether a local blend or full refinish is the right approach for the colour. Availability of a replacement bumper, where one is needed, can also be a factor.
Not every cracked or split bumper can be safely repaired — where the plastic has been overstressed, or where a mounting point critical to sensor or radar accuracy is compromised, replacement is the safer route. We'll tell you plainly where this applies rather than attempting a repair that won't hold up.
