Fifteen firefighters were called to Saltash earlier this morning after fires in two sheds had spread to two vehicles.
Several emergency calls were received at around 5am to the incident involving a single outbuilding at Polborder.
Nine firefighters from Callington on two appliances were mobilised, and then a second call was received stating another shed was on fire and there were two cars also being threatened.
Six firefighters from Saltash were sent to the scene and discovered the fire had spread from the sheds to involve two cars.
Crews used four breathing apparatus and two hose reels to extinguish fires.
At this time the cause of the fire is not thought to be suspicious.
