Firefighters saved a Melcher Street house that caught fire Wednesday, but broken windows and the lack of power made the building uninhabitable.
There were no injuries in the fire reported at 11:20 a.m., when firefighters were told a bedroom was on fire.
Johnstown Fire Chief Bruce Heberer said the bulk of fire damage was confined to the upstairs bedroom, but the much of the two-story home sustained smoke and water damage.
Firefighters had to smash out windows and cut power to the home, so it was unlikely to be re-occupied right away, Heberer said.
The fire was not considered suspicious but was still being investigated later Wednesday.
