Loudon, NH May 10-2025. A three alarm fire completely leveled a century old barn and home on the evening of May 10th in Loudon,NH. The home owner called 911 to report that his "wood shed" was on fire and was attached to his farmhouse. Concord Fire Alarm dispatched the Loudon fire department along with numerous mutual aid towns automatically at 1939 hours. The Currier Road farmhouse which is in a rural section of town was built in 1820. The farmhouse including a barn and other structures on the property overlooks miles of scenic rolling hills. It was once a working farm during World War II and is located on Currier Road. Billows of black smoke could be seen for miles as Loudon's Fire Chief Tom Blanchette quickly called for a second alarm while responding. Loudon Engine 2 arrived at 1948 hours and reported heavy fire all throughout the structure. The Chief then requested a third alarm at 1951 hrs. The approximate 60X40 wood shed structure was attached to a large 2 1/2 farmhouse and was fully involved.Heavy fire was rapidly spreading to the main house as firefighters made an interior attempt to prevent the fire into the home. Chief Blanchette quickly withdrew the members due to the heavy volume of fire and lack of a water. A tanker shuttle and porta-tanks were set up and water was established from a nearby cistern and a fire pond. Two firefighters were treated for minor injuries at the scene. Firefighters remained on the scene through out the night extinguishing pockets of fire. The fire is still under investigation.
