abandoned contractor property

The Contractor unexpectedly demanded additional payment beyond what our contract stipulated, pressuring me to accept an expensive change order for an upgraded “bomb-proof” impact window instead of the standard hurricane impact window initially discussed. This request was not only above my budget, but also not clearly itemized in the original agreement. The cost the Contractor quoted for the window alone exceeded $2,000. The Contractor has effectively abandoned the uninstalled window since October 2024 and failed to meet the contract terms, do I now have the legal right to claim or dispose of this unclaimed property as I see fit? I need to know if I may sell, discard, or otherwise use the window without risking legal repercussions, and whether I can move ahead with hiring another contractor to repair the damage they left behind. I would greatly appreciate your counsel on this matter, including any relevant Florida statutes, regulations, or case law that apply.
