QUINCY (WGEM) -- The cause of a house fire in Quincy Monday is undetermined according to the Quincy Fire Department.
Firefighters said they responded to the home at 410 Maiden Lane just before 3 p.m. where they could see smoke coming from the roof.
They said someone at Winkings Market at 416 S 4th Street noticed the smoke and called the fire department.
Firefighters said they had to block off Maiden Lane between 4th and 5th Streets as they worked to put out the fire.
They said the fire started in a back addition to the home and spread to the attic causing a lot of smoke and fire damage to the main floor as it went.
“The old homes that were built like this are basically a straight channel from the ground all the way up," Deputy Chief Steve Salrin said.
"So what happens if it starts at the bottom, it's going to end up at the top and that’s what the guys found was it looked like the fire started on the ground floor and got up to, at least, the attic area. There were reports from the guys coming out that the second floor was in pretty good shape."
The people who live in the home were not there when the fire started. They arrived while firefighters were trying to put it out.
Firefighters said they did pull a dog from the home but have not said how the animal is doing.
The Quincy Fire Department, Quincy Police, and Adams County EMS all responded to the scene.
