Whether it’s the result of a collision or a breakdown, your vehicle will require auto body repair at some point. And when it takes longer than you think it should, that is annoying. And if that’s taking longer than the collision repair technician told you it would take, that can be annoying. And if the repair doesn’t last long? Then you’re probably furious.

But just how long is collision repair supposed to take? And how long should you expect the results to last?

Collision repair length

It probably won’t surprise you to learn that the length of an auto body repair ‌depends on the kind of repair it is. Replacing a busted headlight? The actual labor time on that might be under 15 minutes. Overhauling an entire transmission? Well, that’s going to take quite a bit longer.

Before beginning a collision repair, the technician involved should give you an estimate of when you can pick up your vehicle. For a service you’ve scheduled ahead of time, such as changing your winter tires to all-seasons, that should be an easy-to-predict, few-hour job. But for collision repairs that involve diagnostics, a lot more guesswork and variability are involved. 

What factors affect the length of an auto body repair?

Just as there are numerous types of collision repair, there are numerous dynamics that determine how long a repair takes to complete. Here are some considerations affecting auto body repair:

The extent and type of damage

The first factor is perhaps the most obvious. How badly a vehicle is damaged will have a great impact on how long a collision repair takes. For example, surface-level damage, such as scratches and minor dents, is easier and quicker to fix than structural damage to the frame or crumple zones. 

Similarly, having to repair or replace a single panel is quicker than restoring multi-panel damage. Another key factor in collision repair is whether the crash was forceful enough to deploy the airbags. If so, this triggers additional safety system inspections and replacements.

Parts availability

You’ve probably heard about supply chain issues affecting multiple industries several hundred times so far this decade. Parts availability affects the entire global economy, and auto body repair is no exception. Back-ordered or discontinued parts, especially for older or rare vehicles, can take weeks, and sometimes months, to deliver. Furthermore, if your vehicle requires parts that need to be sourced from overseas, this adds on time. Original equipment manufacturer (OEM) parts can also take longer to source versus aftermarket parts, as do dealer-only parts that can’t be sourced through general suppliers.

These bottlenecks can be frustrating for both auto body repair shops and drivers alike. If your vehicle is undrivable because it’s missing one measly part you’ve been waiting on for weeks, it’s natural to be frustrated. And less-than-professional collision repair businesses have been known to blame supply chain issues when their own forgetfulness or procrastination are the cause. However, if your technician is honest with you and keeps you apprised of the situation, then all you can do is trust them and wait.

Shop workload and staffing

Sometimes the collision repair itself isn’t the problem; it’s the shop. And it might not even be the shop’s fault, unless they simply haven’t hired enough technicians. (Though finding the right number of qualified collision repair technicians isn’t always easy.)

How busy is the auto body shop? If there are a lot of vehicles ‌ahead of you, it’ll take time for them to get to yours. That’s frustrating, but at least it indicates that many people trust this business. Furthermore, technician skill level and specialization play a part. For example, aluminum body panels often require specific expertise, so these repairs can take longer.

Insurance and administrative processes

Ah, bureaucracy, everyone’s favorite! Sometimes it just takes a while for a claims adjuster to inspect and approve a claim. And disputes between the shop and insurer over repair methods or costs will also prolong the ordeal. Last, there may be supplemental claims that arise if a collision repair tech discovers hidden damage mid-repair.

Paint and finishing

Fixing a scratch sounds easy enough, but getting the right automotive paint match isn’t always that simple. Custom or rare paint colors often require special mixing and ordering. Furthermore, the number of coats required and the drying and curing time between each also matter.

Vehicle complexity

Sometimes it’s not the damage that’s complex, it’s the vehicle. Advanced driver assistance systems (ADAS), such as cameras and sensors embedded in bumpers or mirrors, require recalibration after collision repairs. And electric and hybrid vehicles with high-voltage components need specialized handling. Last, luxury or exotic vehicles with proprietary materials or systems require special consideration and more time.

Weather and environmental conditions

The humidity level and temperature affect paint application and drying times. If an auto body repair shop lacks a climate-controlled paint booth, this can prolong how long it takes to finish the job.

So, how long should collision repairs last?

When discussing length and vehicle repairs, we could be talking about two things: how long the repair takes and how long the repair lasts until you need another one. This second question is trickier to answer. Not only does it depend on the type of repair, it also depends on your driving style, how often you drive, where you drive, and just pure luck.

Here are some very rough estimates regarding how long certain repairs last:

• Windshield repair (chip/crack fill): If done right, it should hold indefinitely.
• Windshield replacement: A full replacement, when installed correctly, should last the life of the vehicle. Obviously, another collision or impact can shatter a new or repaired pane.
• Frame straightening: When done with the right knowhow and tools, a straightened frame can last the life of the vehicle. However, a previously bent frame may be more vulnerable to future damage, and some insurers or buyers will flag it as a structural concern.
• Wheel alignment: Typically lasts a couple of years or about 20,000-40,000 km under normal driving conditions. 
• Full or partial repaint: A high-quality professional repaint can last 10-15 years with proper care.
• Bumper repair or replacement: A repaired or replaced bumper, properly finished, should last at least five years, and maybe more than ten.
• Headlight replacement: A new headlight will often last for the life of the vehicle, barring a collision.

The right auto body repair

The right fix sometimes takes longer, but it also lasts a lot longer. If you find the right collision repair shop, not only will they give you a clear estimate of how long the process should take, but the results should last long, too.
