We provide mold treatment services and performed a job in NC in May entailing a 14 hour drive. At one hour away the customer cancelled. Then called back and said 1/2 now and 1/2 in 30 days. We did the job being within an hour. We were told it worked. As 2nd payment approached, they said they did a mold test and it showed mold in the crawl space where water leak was. Our re-application warranty has certain specific perimeters which were not met rendering the warranty not applicable. It would also requirement paid in full status. This demand is an excuse to not pay knowing we're not coming back given no warranty. Can we file a lien?
Without knowing the lien laws in North Carolina, I would say that you could file a lien.
