Insurance deductibles are due at the completion of the repair process to the repair center. Your insurance adjuster can answer any questions you may have regarding your policy, coverage and applicable deductibles.
Be cautious of anyone offering to save you the cost of your deductible! Ask specific questions on how they plan to absorb this cost. Will all repairs be made per industry standard and will all the proper parts be used? This is not usually an offer with your best interest in mind or the protection of the investment you have in your vehicle.
