Rebuilt a partially burned garage, owners were reimbursed by insurance for all contents and didn't want to mess with the smoke smell, so we were allowed to keep anything we wanted out of it. Ended up with lots of hand tools, cords (only smoke damage), even two pairs of snow shoes. Everything washed up with a little soap and elbow grease, and two years later you hardly notice the smell anymore.
Also did a restaurant to replace one that burned in the kitchen. Had wood framed flat roof. Amazing that the structural guys said that since the charcoal on the rafters was less than 1/4 inch deep they did not need to be replaced.
