This photo depicts a well-executed drying plan, by our well trained and IICRC certified crew. A Class 3 water damage restoration in a house in the Nashua, NH area means that the entire space was affected by water from the ceiling, down through the walls and all the way to the floor. The bubbled-up plastic over the floor is referred to as “tenting,” which is an effective technique for saving expensive hardwood flooring. Warm, very dry air from a desiccant dehumidifier is ducted and trapped over the flooring to pull deeply embedded moisture out of the wood. You have to know what you are doing with this, or you can over-dry the wood and cause it to split.
