ABOUT 50 fire fighters from 12 stations last night extinguished a fire which destroyed a cleaning products factory at Riverstone.
The cost of the damage to the building and stock at the Loftus Street factory was estimated at $600,000.
Police and fire officers were at the scene this morning to investigate if the fire was intentionally lit.
Jamac Cleaning Supply and Manufacturing Pty Ltd managing director Amy McKenzie said she learnt about the fire at about 3am. The fire is believed to have started at about 11pm .
She said the company was a family business run by her husband Jeff, their son and employed about three workers.
She said the family had been running the factory for about 10 years.
‘‘We plan to rebuild the factory as soon as possible to provide jobs to our employees as well as people who sell and distribute our products,’’ she said.
Mrs McKenzie said she suspected the fire could have been started by ''burglars or mischief makers'' saying her premises was broken into twice about three years ago.
‘‘In the previous case they stole some money and our van to use for other criminal activities.’’
Huntingwood Fire & Rescue Centre Duty Commander Dave Taylor said investigations were still under way.
He said the blaze caused the roof of the premises to collapse but that fire fighters stopped the blaze from spreading into neighbouring properties.
