They called 911 shortly before 5 p.m. and firefighters arrived in time to contain the blaze to a single room in the three-storey home, Capt. Chris Aubrey said.
The crew put out the fire within about 15 minutes.
There was nobody in the house at the time, Aubrey said. Two cats were unharmed.
He estimated the damage at about $10,000, mostly due to smoke.
The cause is still under investigation.
