I hired a handyman to install spray foam insulation. He was paid in full prior to the project. He verbally told me he would be doing the work, his invoice states he will be doing the work, the invoice is under his name (not a company name). He (without my knowledge) hired another company to do the work. 73 days later this other company came to me door. I gave him the address and phone numbers for my handyman. He stated he wasn't paid..and I thought it could be a scam. 85 days post install they filed a lien on my property. This was the first time I had the name of the company, and dollar amount. Is this lien valid? No pre-lien notice, they were not authorized to work on my property, my handyman did not have the authority to bring in additional people, and the amount this company charged was well over the expected price. Last, the work has unfinished repairs.
