Owners of a North Beach dry-cleaning business are distraught after a fire gutted their business overnight.
Firefighters were called to Royal Dry Cleaners on Flora Street at 8.15pm after smoke was seen billowing from the building.
Business owner Phil Gianoli said he had no idea what caused the fire, which destroyed his business and a number of expensive items inside.
"A customer called me and told me the shop was on fire," he said. "It is pretty bad, but what can you do."
Mr Gianoli, who started the business more than a decade ago, could not put a dollar figure on the damage.
Customers stood outside as the business burned and one man exclaimed "my suit is inside".
Mr Gianoli said priceless items including wedding dresses were inside at the time of the fire.
The business services at least two other drycleaners in the metropolitan area.
No people were inside the business at the time and it took 20 firefighters about 15 minutes to contain the blaze.
Department of Fire and Emergency Services district officer John Kagis said the fire did not appear to be deliberately lit. "It looks accidental but the cause is undetermined," he said.
DFES investigators will look into the cause. Mr Gianoli said the business was insured.
