Traditionally the job is done with big humidifiers, but Cressy's work in the field convinced him it could be done more efficiently by forcing hot, dry air in to replace moist air removed from the room. It's a process akin to a blood transfusion, he said.

Traditionally, restoring water-damaged buildings means dumping the carpets, the molding and part of the walls where the water collected. Cressy says his method works efficiently enough so that those parts of the building can be salvaged, saving money for the building owner in the long run.
