Hello, I hired a contractor to remodel my house (in Culver City California) and they finished the project in early August. I told them there were many items which needed to be fixed (for example damages to my property) before I send them the last paycheck. They sent 2 people to fix 2 of the damages (caused by their crew) and charged me for it on an invoice dated 8/28/2019. That is the last invoice I have from them. I moved in at the end of September. They had some people come in 10/25/2019 to do a minor fix (install a door). I have a dispute with them about some things they charged me for. They want to file a mechanical lien against me. Have the 90 days past, since the last day they actually worked on and billed me for or does the last time somebody from they company came to my house count, even though it was just to do a small job for 1-2 hours? Thank you for your time! Ivo
