If you had to file an insurance claim that would not have been necessary but for his poor workmanship, then you can argue that you owe him nothing because he breached his express and/or implied contract to you, causing you harm in the process.
If he completed the job, or it is now complete, then there is an argument to be had that you owe him, at least at an reduced rate, for this services. If you drill down a little further, he really only has a good faith argument to be paid for the material costs associated with the job...not the labor, since the labor was not satisfactory - moreover, it actually caused harm.
In short, though it can be more complicated, I think you should request that he provide to you an itemized list of the material costs associated with the job. You can reimburse him for the material costs and that should be all you reimburse for relative to the job - unless he fixed that which precipitated the insurance claim and completed the job after the fact. If that is the case, then he does have an argument for reimbursement of materials and labor AFTER the event that precipitated the insurance claim.
Please rate my answer positively and let me know if you have any other questions or comments.
Best wishes going forward!
