A Mudgee house was severely damaged in an early morning blaze on Tuesday when the unoccupied building was engulfed in fire.
At 5.40am on Tuesday morning Fire and Rescue NSW crews were called to the fire in a house at Paterson Street, Mudgee.
They arrived to find the house well alight and conducted their interior search and rescue and internal fire attack, which was delayed slightly as the house showed signs of roof collapse.
No persons were reported or located at the scene.
The fire was brought under control by 7.37am.
The blaze was confined to the one house.
Three fire trucks were called to the scene, two from the Mudgee station and one from Gulgong.
Investigations are underway to determine the cause and the area of origin of the fire.
The time of the blaze is a reminder for residents to check that their smoke alarms are operational in order to wake anyone when a fire takes hold.
FRNSW is reminding people to prepare their homes against the risk of fire during winter, as the cooler months see a 10 per cent increase in the number of house fires.
