A water heater in a finished basement failed, causing water damage to walls, carpet, wood trim, and insulation. The extent of the damage was located with a hydrosensor. The unsalvageable building material was neatly cut out, disposed of in contractor trash bags, and photo-documented. All furniture and wall hangings were moved and protected with plastic from the work area. The water damaged areas were treated with Benefect, which is a botanical disinfectant. The cement floor was washed and scrubbed. After all cleanup was complete, drying equipment was placed to dry wood studs and cement floor. Warm air from dehumidifiers and air movers drop humidity level below 50 percent to prevent microbial growth.
