A renovation company in nc we hired after a fire 2 years ago (june 2019) never finished up their punch list so we held back final payment telling them we'd hand it over upon completion. However, they never came back to do complete the work my insurance company paid for and claimed everything was basically done- which it really wasn't. We completed the punch list ourselves so we could sell the house today. We lost several other offers due to them still not being done this year ( april 2021). Then they tried to get me to sign a certificate of satisfaction for the work- which I refused given the length of time they already had drawn this renovation out. We finally sold the house in July 2021- clean title. My question is can they still take out a mechanic's lien on the house even though we sold it? Or will they have to take me to court to discuss a reasonable final payment since we finished their punch list ?
