If you've paid him in full, and someone is demanding more in order to release the lien, I'd send them a quick certified letter letting them know it is paid in full, and if any delays in removing the lien cause you any king of damages, you most certainly will be coming them for those costs, along with attorney fees.

Odds are they did the damage and they know it.

From this discussion it appears you may have been damaged by negligence.
