“When you file a claim with an insurance company and you choose to close it or they deny it, the claim is closed.
When you file a new claim, you won’t be penalized for the previous, claim as it was closed without payment. If you were ever to switch insurance carriers, it would likely show up as closed without payment or it wouldn’t be reported at all.
Since you did just file another glass claim that was denied, you’ll likely need to provide proof that this is a different claim. This may be difficult as part of the damage was already existing. You should reach out to your insurance carrier again and provide proof.
You can show them the two cracks and indicate which is new and which is older. While they may not agree to cover the full replacement, you may be able to negotiate some type of coverage.”
