The kitchen and finished basement were both water damaged by broken pipes. The basement incident was from a fully depreciated hot water heater and the kitchen from burst piece of baseboard heat. The attic was a result of vapor migration from a dirt basement and a bathroom fan venting into the attic. We totally gutted the kitchen and basement, cleaned all the surfaces and sprayed everything with an antimicrobial sealant. For the attic, we installed a vapor barrier in the basement, vented the bathroom fan to the exterior, removed the mold and installed an attic ventilation system.
