Comercial store got broke in, glasses are broken

[Lisa Forde]

Hi all, my comercial tenant just got broke in and glasses got broken. In this case should landloard be the one who fix it or tenant? We both have insurance. Tenant has insurance and I do too. Should I contact my insurance company to fix that or his?

Last question if I use my insurance company will that cause my future premium to be raised?

First time happens to me. Things getting really bad now.

Thank you!
