My company was run off a window replacement job by the customer the day we were to finish the project

my company was run off a window replacement job last Thursday (the day we were going to finish trimming the exterior of 6 windows, the customer texted me at 6:22am to tell me my crew was not allowed to work at his home that day, we proceeded to show up to his house to remove our tools and enclosed trailer so we could work at another job that day, one thing escalated to another and the local police had to get involved to assist me with a civil recovery of my companies property as the customer backed a truck up tight to my trailer and deflated his tires. We were able to get out property out of the customers home and remove our trailer with the assistance of the local Oak Creek, CO police. He reported my company to my local building authorities in Routt County, CO for not pulling a replacement window permit, as the homeowner wanted to cut as many costs as he could so we verbally agreed he would dispose of jobsite debris, customer would self perform painting his own interior trim and pull his own permit. We know we should have put these details in writing. moving on, we don't feel like its a safe environment to return to try to finish this job. We also have an inspection report that indicates he has created some sabotage to the work we have completed, as the inspection report indicates that my company cut into headers above windows, and cut through sheathing on the customers home. there was 3 layers of siding, no wood sheathing on this old house, 3 layers of interior wall materials, if anything we had to add new dimensional lumber to several window opening as the existing window openings were in pretty poor condition. The customer is texting us constantly, they are now saying we killed one of their animals, we assume they are referring to some chickens they have loose in a fenced in area due to lead exposure. many facets the customer is working on to get something out of us we presume. We have zero intention of trying to complete this project (6 windows of exterior trim and 1 window of interior trim remain), we really have no intentions in trying to collect a final payment from this customer either. happy to provide our contract agreement for your review, our contract is very iron clad. My current worry is what recourse does customer have being he ran us off his property before we could finish the job in total, and can we just call it a day and leave things where they currently stand. should we be preparing to file a lean and credit back the monetary value of the work we were not allowed to complete in the final invoice again we have no interest in trying to take this guy to court or collect the remaining $10,800 owed to the contract price I am prepared to site "abnormal site conditions"
