We are a subcontractor on a job in Austin TX. Our original contract was for the amount of $4,518.00 which we were paid. We have a change order in the amount of $2100.00. Catalyst needed a plumbing permit and an inspection which we provided for them with this change order. They were billed for the CO on 12/14/2021, after several attempts to contact them with no success they were sent a notice intent to lien thru Levelset. We had not sent the notice so we had to do that before we could file lien. We have not worked on the job since August 31, 2021. Can we still file that lien? I am still getting no response.
