Firefighters say the blaze at the River Road home of Dennis Celinski and Curtis Piszenski started at about 11:30 p.m. Firefighters were on the scene until about 6 o’clock Thursday morning.
Route 255 was closed between Caledonia and Weedville while firefighters were battling the blaze. Flames damaged Windstream Fiber Optic Cable and West Penn Power Lines, causing a telephone outage in the area.
One firefighter suffered a minor injury. He was taken by ambulance to Elk Regional Health Center, where he was treated and released, according to state police fire marshal Greg Agosti.
The Red Cross provided food, clothing and shelter to Celinski and Piszenski.
The cause of the fire remains under investigation.
