Airways is not a general contractor for fire damage restoration, but restoration companies frequently bring us in to clean the ventilation systems of a building which has experienced a fire. The biggest challenge is usually to get the smoke smells out of the system. If the ductwork is lined with insulation, that may not be possible and the insulation may have to be removed. Airways can remove insulation, as well as get the smoke residue and smell out of uninsulated ductwork.
