A chimney fire Wednesday evening did about $10,000 worth of damage to a Duxbury home .
Duxbury fire officials say they got the call at 5:54 p.m. Wednesday for a spreading fire at 50 Chestnut Street.
The homeowners were at the house and were operating a wood stove when the fire started in an exterior metal chimney and extended to the shingles, walls and rear of the house.
19 Duxbury firefighters, two engine trucks and one ladder truck responded to the scene. Crews had the fire knocked down by 6:30 p.m.
