I've already paid them 90% of what is owed, very early and then immediately when invoiced. The remaining is only because they did not include an additional invoice at the time. Now, they damaged my floors and are reimbursing me, but they will not give me the check until I've paid them...and today they threatened to file a mechanic's lien. This does not seem right given what has transpired. I have all emails to prove and show their negligence, but I do not know legally what rights I have.
