UNION, NJ – Union firefighters responded to a house fire on Colonial Avenue late Wednesday night.

Upon arrival to 432 Colonial Avenue crews found heavy fire conditions on the second floor and in the attic, said Union Fire Chief Mike Scanio.  Firefighters stretched multiple hose lines to the second floor to confine and extinguish the fire. The main body of fire was extinguished quickly.

Firefighters opened up all the walls and ceilings on the second floor to extinguish the hidden fire running in the walls. The fire was placed under control in about an hour. There were no reported injuries.  The occupants of the home were unable to return due to fire damage on the second floor and water damage on the first.

Scanio said the cause of the fire is under investigation but does not appear to be suspicious. Mutual aid was brought into town to cover calls while all Union units operated on scene.
