At 1.19pm on Monday (25) one crew from Ely and one crew from Chatteris were called to a fire on Station Road in Wilburton.
Firefighters arrived to find a fire in the chimney of a house and extinguished it. They returned to their stations by 3.45pm.
A fire service spokesman said: “Please ensure that you get your chimney swept and brickwork inspected at least once a year. This will help to prevent a chimney fire.”
