Newton Firefighters put out the flames of a chimney fire before it spread to other parts of the home at 139 Woodward St. Sunday morning.
The blaze began in the fire place, where residents had started a fire, said Deputy Fire Chief James Thorne.
The residents were home and called 911 just before noon, allowing firefighters to knock down the fire quickly.
"It extended into the mantle," Thorne said. "It was starting to get into the walls. We caught it just in time."
No one was injured in the fire.
