That contractor would be sued or even held criminally liable for their actions, because that borders on criminal conduct.
From a civil perspective, you would sue the contractor for damaging the property. He has done something that is equivalent to taking a bulldozer and running a building down. The court doesn’t allow an individual to take matters into their own hands and destroy property. There are remedies set forth, and once you take retaliatory action, you put yourself on the wrong side of the equation.
