Synopsis
A complete auto collision repair estimate must itemize labor, parts, paint, scan fees, and a supplement clause; otherwise, it is incomplete. Committed Collision & Auto Body Center in North Hampton, NH, explains what each line item covers, what red flags to question, and your rights under NH law.
A complete auto collision repair estimate itemizes labor, parts, paint and refinishing, diagnostic scan fees, a projected timeline, and a written supplement clause for hidden damage. If any of those elements are missing, the estimate is incomplete.
That matters for one reason: the estimate is the document that determines whether your vehicle gets a thorough, safe repair or a cost-cut one. It is not just a starting price. It is a plan.
New Hampshire law reinforces this. Under the New Hampshire Motor Vehicle Repair Law, a repair shop must provide a written estimate if you request one. No shop can waive that right as a condition of service.
At Committed Collision & Auto Body Center, we walk every customer through their estimate before a single panel comes off. Here is what that document should contain and what should raise questions if it doesn’t.
What Every Auto Collision Repair Estimate Must Include
Each repair entry on your estimate represents a specific decision about your vehicle’s safety and value. We assess visible damage during the initial inspection, then build the estimate around what we find using OEM repair procedures and industry-standard estimating software. The table below covers the six components that belong in every estimate, and why each one matters.
| Estimate Component | What It Covers | Why It Matters |
| Labor hours | Time required per repair procedure | Vague labor entries can hide underbilling or overbilling |
| Parts list | OEM or approved aftermarket parts, itemized by component | You should know exactly what goes on your vehicle |
| Paint and refinishing | Primer, base coat, clear coat, materials | Paint involves multiple stages — each has a cost |
| Diagnostic / scan fees | Pre- and post-repair OBD-II scan charges | Required by most manufacturers; a missing fee may mean a skipped scan |
| Estimated timeline | Projected completion milestones | Manages expectations; subject to parts availability |
| Supplement clause | Written notice that hidden damage may be found post-disassembly | Protects both the shop and the customer from disputes later |
Pay close attention to the supplement clause. It signals that the shop understands repairs change once the vehicle is opened up and that they will communicate those changes to you before proceeding. On the scanning side, we use OEM-approved OBD-II tools, including factory scan equipment for Hyundai, Kia, GM, Ford, Toyota, Mazda, and Nissan. That specificity matters because generic scan tools can miss manufacturer-specific diagnostic codes.
On the parts side, we prioritize OEM (Original Equipment Manufacturer) parts for fit and safety. We do not source components from Amazon, eBay, or unknown vendors. For body collision repair, the parts list on your estimate should be specific, not generic.
What an Estimate Should Not Include or Leave Out
Red flags on an estimate are just as important as what is missing. Here are three that should prompt questions before you sign.
Vague or Bundled Line Items
Entries like “body repair — miscellaneous” with no breakdown are a problem. You cannot verify what was done, dispute a charge with your insurer, or hold the shop accountable if something was skipped. A bundled line is unauditable.
Every procedure should be named and individually priced. Ask for a line-by-line breakdown before you authorize anything.
Missing Diagnostic Fees
No scan fee on an estimate does not mean scanning is free. It often means scanning is being skipped entirely.
According to CCC Intelligent Solutions’ Q2 2025 Crash Course report, nearly 87% of Direct Repair Program (DRP) estimates included a pre-repair scan as of Q1 2025. If yours does not, ask specifically whether it is included or simply absent.
What separates a qualified collision repair specialist from a general shop is the consistent inclusion of these steps. Pre- and post-repair scans are required by most manufacturers. They belong on the estimate, whether billed separately or rolled into the labor total.
Pressure to Sign Immediately
A reputable car collision repair shop gives you the estimate in writing and time to review it. No pressure. No urgency tactics.
Under New Hampshire law, your authorization is required before any work begins. A shop that discourages you from reading the document carefully may be working against your legal rights, not in your interest.
Why Estimates Change After Disassembly and What to Expect
The initial estimate documents visible damage. It cannot show what is hidden beneath panels, bumpers, and structural components.
Once panels are removed and authorized teardown begins, our technicians look for hidden damage that is not visible from the outside. A bumper cover can conceal significant structural issues. Internal components, missing parts, and damage to adjacent areas all become visible only at this stage. None of that appears during a walk-around inspection. This is not an upsell. It is the physical reality of repairing modern vehicles.
Any newly discovered damage requires a revised estimate; a written update that documents the additional scope. That updated estimate must be shared with you and your insurance carrier before work continues. No reputable shop proceeds without your approval.
Vehicle complexity is rising every year. CCC Intelligent Solutions’ Crash Course 2026 data shows the average total cost of repair reached $4,818 nationally in 2025. That figure reflects growing vehicle complexity, not inflation alone. Thorough inspection once panels are removed is a direct response to that complexity, not an add-on.
In a significant collision, a careful shop often finds additional hidden damage after teardown or detailed inspection.
How Insurance Affects What Appears on Your Estimate
Insurance adjusters write estimates based on visible damage and the coverage policy. They are not trained in OEM repair procedures. Their initial estimate may undervalue labor, omit required scans, or default to non-OEM parts.
That does not mean you are locked into their version of the repair. Under New Hampshire Insurance Department guidance, you may choose the repair facility of your choice. Your insurer may recommend a shop, but the decision is yours.
New Hampshire law requires a written estimate if the customer requests one. The estimate must itemize the work to be done, give an estimated price for the parts and labor needed, and include an estimated completion date. The shop must also get the customer’s authorization before beginning the work.
Our estimates include documentation and photos for every repair procedure. That documentation gives us what we need to negotiate with your carrier if a charge is disputed. When an insurer refuses to cover a required procedure, we reach out to you right away. We explain your options. We never quietly skip the repair or absorb the cost without your knowledge.
A Note for NH Seacoast Drivers Bringing Vehicles In This Summer
Vehicles on the New Hampshire Seacoast accumulate road salt exposure from November through early April. If you are dropping off a vehicle now after a winter or spring incident, corrosion or surface rust found during disassembly may be pre-existing, not caused by the accident.
A thorough estimate documents pre-existing conditions found during teardown and separates them clearly from accident-related damage. That distinction matters for two reasons. Only accident-caused damage is claimable on your policy. Pre-existing conditions are not. A shop that conflates the two creates problems for the customer, the carrier, and the repair record.
This documentation also protects you directly. Without it, you could be held responsible for conditions that existed before your accident ever happened. At Committed Collision & Auto Body Center, we photograph and note pre-existing conditions at the time of disassembly so there is never any ambiguity later.
Before You Sign: What to Verify
Run through these four checks before authorizing any repair:
- Every line item is named and individually priced. No bundled or vague entries.
- Diagnostic scan fees are listed, or you have confirmed in writing that they are included in labor.
- A supplement clause is present, acknowledging that hidden damage may be found after disassembly.
- You have a projected timeline and know how the shop will notify you of any changes.
Common questions
What should a collision repair estimate include?
Labor, parts, paint, scan fees, a timeline, and a supplement clause. Each item should be individually named and priced.
Can my estimate change after I drop off my car?
Yes. Disassembly often reveals hidden damage. Any change requires a written supplement and your approval before work continues.
Do I have to use the shop my insurer recommends in NH?
No. New Hampshire law gives you the right to choose your own repair facility, regardless of insurer preference.
What if there is no scan fee on my estimate?
Ask specifically. Pre- and post-repair scans are required by most manufacturers. If the fee is absent, the scan may be skipped.
What a Complete Estimate Reflects About the Shop
An estimate’s thoroughness is a direct reflection of how a shop actually works. It is not just software output. It reflects training, equipment, and commitment to manufacturer repair standards.
At Committed Collision & Auto Body Center, our I-CAR Gold Class certification and ASE-certified technicians mean every estimate reflects what manufacturers actually require, not what is convenient to bill. Structural line items are backed by measurements from our Chief 3D Laser Measuring System. Paint and refinishing charges reflect the actual multi-stage process we perform in our USI spray booths using Glasurit 100 Line waterborne paint. Nothing is estimated loosely. Nothing is charged without proof.
Our limited lifetime warranty covers workmanship, paint, and parts, and it stays in effect throughout your ownership. That is only possible because our estimates account for everything the repair genuinely requires. Every charge is documented before a vehicle leaves our facility.
For those seeking auto collision repair in North Hampton, NH, that standard applies to every vehicle we take in, major or minor, single panel or full structural repair. Here is a Google review by Nicholas B.: “I scheduled 2 of our vehicles for inspections and repairs and was blown away by the communication, the education, and the value. All auto repairs can be sticker shock-inducing; however, the people at Committed Collision were able to explain the reasoning behind their recommended repairs. They also allowed me to take my vehicle elsewhere to get a second opinion. No pressure, just calm reasoning. I felt very comfortable with their service. I will be going back and recommend others do as well.”
