Garage tenant won't move his stuff for repairs

[Phil Goodwin]

I have a 10x20 garage rented to a guy that is storing personal property:  tools, furniture, books, clothing, etc.  There is mold growing on the drywall ceiling.  I hired a mold remediation company to inspect the garage and the mold guy thinks the water is intruding through the brick and mortar wall.  He won't know for sure until he tears down the ceiling.  The mold guy said the garage needs to be empty in order to tear down the ceiling.  The garage is packed full. there is no way to move the stuff to one side, and I do not have any other space available, etc.  There is some mold growing on some of his stuff and I can understand that he would be a little upset.  However, my tenant has really been uncooperative throughout this ordeal over the last several weeks, repeatedly cursing at me over text, calling me a scumbag in one of the texts.  His lease goes through 9/30/19.  I do have an indemnification clause in the lease protecting me from any claim against damage.  I offered to tear up the lease, let him move out, and refund him 1 month's rent of $120 to offset his moving costs.   He refused and just continued to yell at me.  He refused to let me move this stuff too.  What do I do?
