Auto Repair Estimate Review
Make sure your repair estimate covers everything. We review estimates for accuracy and help you understand the supplement process.
Why Review Your Repair Estimate?
Insurance repair estimates don't always cover the full cost of proper repairs. Missing items, incorrect labor rates, and overlooked damage are common issues. As your auto accident property damage consultant, we review your estimate to help ensure nothing is missed and that you receive the full scope of repairs you're entitled to.

Common Questions
What is a supplement?
A supplement is an additional estimate written when hidden damage is found during repairs. It's common and expected — but the process of getting it approved can be frustrating without guidance.
Should I use the insurance company's recommended shop?
You have the right to choose your own body shop. We can help you understand the pros and cons of different options and what to look for in a quality repair facility.
What if I disagree with the repair estimate?
You have the right to get a second opinion. We can guide you on how to approach this and what documentation to gather to support your position.
Understanding the Repair Estimate Review Process in California
When your vehicle is damaged in an accident, the insurance company prepares a repair estimate using industry-standard estimating software such as CCC ONE, Mitchell, or Audatex. These systems calculate repair costs based on standardized labor rates, parts pricing, and repair procedures. However, the initial estimate often does not capture the full scope of damage — especially internal or structural damage that is only visible once the vehicle is disassembled at the body shop.
This gap between the initial estimate and the actual cost of proper repairs is where most disputes arise. Insurance estimates may use lower labor rates than what qualified shops charge in your area, specify aftermarket or recycled parts instead of OEM components, or omit procedures that are required by the vehicle manufacturer for safe repairs. Without understanding what to look for, drivers often accept estimates that result in incomplete or substandard repairs.
The supplement process exists to address additional damage discovered during repairs, but navigating it requires understanding how to document hidden damage, communicate with insurance adjusters, and ensure that the body shop is writing thorough and accurate supplements. Many drivers are caught in the middle between their shop and their insurer, unsure of what is reasonable or what their rights are.
Auto Damage Advisors provides consulting guidance for California drivers who want to ensure their repair estimate accurately reflects the work needed. We review estimates for completeness, identify potentially missed items, and guide you through the supplement process so that your vehicle is repaired properly and the insurance company pays for the full scope of work.

Common Mistakes Drivers Make With Repair Estimates
Accepting the Initial Estimate Without Review
The first estimate from an insurance company is rarely the final cost of repairs. Hidden damage, overlooked procedures, and parts pricing differences are commonly identified during the repair process. Reviewing the estimate before authorizing repairs helps ensure completeness.
Not Understanding OEM vs. Aftermarket Parts
Insurance companies may specify aftermarket or recycled parts to reduce costs. While sometimes acceptable, these parts may not meet the same quality or fit standards as OEM components. Understanding your rights regarding parts selection — especially for newer vehicles — is important.
Choosing a Shop Based Solely on Insurer Recommendation
You have the right to choose your own repair facility. Insurance-preferred shops may prioritize the insurer's cost targets over repair quality. Selecting an independent shop that works in your best interest can result in more thorough repairs.
Not Documenting Hidden Damage During Disassembly
When the body shop disassembles your vehicle and discovers additional damage, it must be thoroughly documented and photographed before a supplement is written. Failing to document this stage properly can lead to supplement denials.
Ignoring Manufacturer Repair Procedures
Vehicle manufacturers publish specific repair procedures for their vehicles. If the insurance estimate does not include required procedures — such as calibrations, scanning, or specific repair methods — the final repair may not meet safety standards.
Frequently Asked Questions About Repair Estimates
Why is the insurance estimate lower than the body shop's estimate?
Insurance companies use standardized estimating software that may not include all visible or structural damage. Additionally, labor rates, parts specifications, and included repair procedures may differ between the insurer's estimate and what the body shop determines is necessary. The supplement process is designed to reconcile these differences as hidden damage is discovered.
Can I request OEM parts for my repair?
In many cases, yes. Your right to OEM parts depends on your policy language, your vehicle's age, and California regulations. Newer vehicles and lease or finance agreements may have specific OEM requirements. Understanding your policy provisions and communicating your preference to both the insurer and body shop helps ensure the parts you want are used.
What is a supplement and how does it work?
A supplement is an additional estimate written when the body shop discovers damage beyond what the initial estimate covered. This typically happens during disassembly when hidden damage becomes visible. The shop documents the additional damage, writes the supplement, and submits it to the insurance company for approval before proceeding with those repairs.
Can I choose my own body shop?
Yes. California law gives you the right to have your vehicle repaired at the shop of your choice. The insurance company cannot require you to use their preferred or recommended facility. However, they may send a reinspection adjuster to verify the damage and supplement at your chosen shop.
How long should repairs take after approval?
Repair timelines depend on the severity of damage, parts availability, and supplement complexity. Minor repairs may take one to two weeks, while extensive structural repairs can take several weeks or longer. Parts delays — especially for OEM components — are a common cause of extended repair timelines. Your body shop should provide estimated completion dates and keep you updated on progress.
