Fire authorities were called to the Cathcart home on Reid Road about 4.17pm.

Ararat Fire Captain Rob Starrick said the house was already fully involved by the time emergency services arrived.

"We had six appliances due to the fact it was a more rural property, so (we had) to prevent grass fires."

Crews from Ararat, Moyston and Langi Logan attended.

It took six tankers and some private units about 40 minutes to bring the fire under control.

"We contained it to the actual area (of the property)," Mr Starrick said.

"When we got here it was fully involved so as far as trying to save anything we couldn't, so it was just about preventing it from spreading."

No one was home at the time of the fire and it was a neighbour and a passerby who alerted emergency services.

Ambulance Victoria was called as a precaution.

"There were no fatalities, nothing like that," Mr Starrick said.

"The ambulance was here as a preventative measure as far as smoke and that sort of stuff, but nobody suffered from smoke, which is good."

The cause of the fire was undetermined but Mr Starrick said fire investigators will be brought in.

"Fire investigators will check it out, see what's going on and ... go from there," he said.
