We hired someone off Craig's list to encapsulate crawl space. New construction. $2800. After the 1st few days of work we paid 2 of his employees $700 for labor and they came back the next day to complete the job. However the work was so sloppy. He agreed and said he would fix it. After 3 attempts the job is still not acceptable. We have had the county inspector and another company to look at it. It doesnt meet nc code requirments and will not pass inspection. Will have to hire a new company to come and clean up this man's mess. We still offered to pay $600 in materials. He said no. He claims now he has over $1300 in materials(including 4500sq ft of plastic only need 2100 sq ft, $200 for 18 screws etc). We asked him for receipts and he won't provide them. He is sending my husband nasty text and emails. No professionalism. After some investigating we find that he recently changed the name of his company and has multiple complaints for crappy work, getting paid and not finishing and over charging for materials. My husband said we can go to small claims court and let them decide. Instead he is now threatening to file a lien against our home. It looks like in NC anyone can just go and take out a lien and only have to give a description of the incident and show no proof. How do we protect our self from him? Please help. We made a terrible mistake and I am a nervous wreck. Thank you
