I have a rental house. The tenants called me about a water leak they caused and told me they contacted a water mitigation company to clean up the damage. This work was done before I was notified of the water leak. The contractor tried to intimidate me into signing a contract and I refused. I told him to have the tenant sign it since they were the ones that contacted him. The contractor did no work after the initial water mitigation. My homeowners insurance company paid the contractor $15,331.42 for their work. Now the contractor is threatening me with a lien if I don't pay him $5,089.14 more. He has been harassing me and is now sending me invoices for payment. Can he put a lien on my house after he has been paid? I contacted my insurance company and they said the contractor and the claims adjustor worked together to negotiate the payment amount of $15,331.42. Please help me!!
