We had a water remediation company come out and they indicated they couldn’t give us an estimate for the work until the work was done and that was industry practice. What we thought would be $2500 turned into an invoice of $7200. It’s outrageously high, but they did not give us an estimate or detail what they were going to do and does not seem appropriate for the amount of work they did. I did sign something that looks more like a waiver to protect them if they damage our property. There’s language about payment, legal fees, mechanic’s lien, etc. But is this a contract since they did not give me an estimate? Can they file a mechanic’s lien?
