Advocacy & Precision Claims
Comprehensive Insurance Services
In California, insurance companies cannot mandate where you repair your vehicle. GRANT KO INC works directly with all major insurance carriers while strictly prioritizing OEM repair procedures.
Direct Insurance Billing & All Carriers Accepted
We work directly with State Farm, Geico, AAA, Progressive, Allstate, Farmers, Mercury, and all others. Estimates, digital photo packages, and repair supplement billing are processed directly through insurer electronic portals with zero out-of-pocket stress.
Comprehensive Estimates & Supplement Preparation
Field adjusters frequently overlook internal structural damage on initial driveway visual inspections. Our technicians perform complete mechanical and frame tear-downs to uncover hidden crumple-zone deformation and submit itemized supplemental billing.
Direct Adjuster Negotiations & OEM Standards
We advocate relentlessly for original manufacturer (OEM) parts, factory weld specifications, and non-compromised collision repair methods. We resolve disputes with field adjusters so your vehicle is never repaired with unsafe aftermarket imitations.
Detailed Photo Documentation & Diagnostic Scans
Every claim is backed by high-resolution photographic documentation, 3D laser measuring charts, and full pre- and post-repair electronic diagnostic scans. We substantiate every required labor operation with indisputable technical data.
Diminished Value & Total Loss Claim Guidance
If your vehicle suffered severe collision impact, it may have lost market value even after comprehensive structural repair. We assist with certified diminished value assessments and provide independent valuation defense against low-ball total loss settlement offers.
ADAS Safety Sensor & Radar Recalibration
Modern insurance repairs require mandatory optical calibration for forward collision avoidance radar, lane keep cameras, and blind-spot sensors. We execute in-house static and dynamic recalibration certified to factory specifications.
Rental Car Coordination & Secure Storage / Towing
We coordinate your rental vehicle pickup directly through Enterprise, Hertz, or your policy's rental coverage. Need vehicle intake after hours? We offer 24/7 towing dispatch and secure indoor facility storage throughout the claim lifecycle.
Deductible Relief & Zero Out-Of-Pocket Options
Transparent deductible consultation under California consumer regulations. We assist qualifying policyholders in navigating repair economics, maximizing policy coverage, and minimizing out-of-pocket expenses.
Direct Digital Photo Processing & Fast-Track Supplements
High-resolution electronic photo-mapping and live adjuster telemetry. We submit supplemental repair claims directly through Mitchell/CCCEngine to bypass weeks of bureaucratic adjuster delays.
Proven Claims Protocol
The 5-Step Insurance Repair Process

Secure Intake & 24/7 Towing
Your vehicle is safely delivered to our Sun Valley collision facility. We document property inventory, initiate claim intake, and arrange rental vehicle handoff.

Adjuster Review & Supplement
We meet directly with your insurer's claim adjuster, demonstrate hidden structural damage, and lock in approved OEM repair supplements.

Structural hydraulic pulling, factory welding, baked spray booth refinishing, and full ADAS sensor optical target calibration.

★★★★★
"After a severe collision on the 101 freeway crumpled the rear quarter panel and bent the suspension of my 2024 BMW M4 Competition, I was worried the car would never drive the same. GRANT KO INC took over everything. They fought Geico to use only genuine BMW OEM parts, put the chassis on their 3D laser measuring bench, and the Isle of Man Green metallic paint match was 100% factory perfect. True master craftsmen."
★★★★★
"State Farm originally tried to write an estimate using reconditioned aftermarket parts and missed internal frame rail distortion. The team at GRANT KO INC tore down the front end, documented all the hidden damage with 3D scans, and negotiated a supplemental claim for complete brand-new OEM structural components. They saved me thousands of dollars and ensured my family's vehicle was structurally safe again."

California Insurance Rights
Collision Claim FAQ
Know your consumer rights under California state insurance laws.
Can my insurance company force me to use their preferred shop?
No. California Insurance Code § 758.5 explicitly prohibits insurers from requiring repairs to be made at a specific facility. You have the full right to select GRANT KO INC.
What if the insurance adjuster's estimate is lower than your repair quote?
That is completely normal. Adjuster estimates are initial rough assessments. We document all internal structural deformation with 3D laser scans, submit itemized supplemental billing, and resolve the discrepancy directly with your adjuster.
Do you offer deductible assistance?
Yes, we offer flexible deductible assistance programs to help minimize out-of-pocket expenses. Call our claims department at (424) 249-5862 to review your policy.
Who coordinates my rental car?
We handle the rental car reservation directly through your policy with Enterprise or Hertz, ensuring immediate vehicle handoff at our Sun Valley shop.
