"Significant damage to walls and ceilings" sound like a clear winner to me. :) I love demolition work. Hire a pro to fix your mess. Your customer will thank you for doing it right. Run a 2" conduit while you are in there. And Atmos speaker locations. And anything else you can think of. Swiss cheese that mother.
