Fire, caused by improperly discarded smoking materials, injured one, displaced five and destroyed a Sterling home Monday night, according to Loudoun Fire and Rescue.
Fire and rescue units responded about 6:15 p.m. to the home at 900 W. Maple Ave. to find smoke and fire billowing from the two-story structure.
Firefighters, authorities said, had a difficult time extinguishing the fire because flames spread to the electrical and natural gas lines within the home. After all utilities were secured, the fire was quickly brought under control.
The fire, which started in the home's covered exterior porch, also caused damage to a neighboring residence.
The estimated dollar loss is $350,000, according to the Fire Marshal's Office.
The American Red Cross was contacted to assist the home's displaced family.
A visiting family member was taken to Inova Hospital in Lansdowne and subsequently transferred to Georgetown University Hospital.
Several pets also died in the fire. No injuries to fire department personnel were reported.
