Damage is estimated at approximately $100,000 after a large dumpster fire broke out between two houses on Vidal Street South on Friday.
Sarnia fire crews were called to the area, near Devine Street, just before 6:30 a.m.
The fire caused obvious damage to the sidings of both houses.
However, Sarnia Fire Rescue Services said a quick response prevented the flames from spreading to the attics and interiors.
No injuries were reported.
Public Education Officer Mike Otis said the cause of the fire was undetermined.
