Earlier this evening during a busy night for both our stations, Engine 606B and Truck 606 were dispatched for a structure fire in Company 23’s area. Units from Ashburn, Loudoun County, and Sterling arrived on scene to find fire through the roof of a home. Ashburn crews pulled a backup hose line and performed a primary search of the residence. Additional units from Leesburg, Arcola, and Fairfax County also responded. The cause is currently unknown and the Loudoun County Fire Marshal’s office will determine it.
