The vandal broke windows and used the company spray-paint to tag them with racist and anti-religious messages.
The owners of the Ridley Township company are outraged.
They say this is the first time in 50 years they've experienced anything like this.
"It looks like these trucks were ransacked. I guess they found some orange spray-paint we use for marking in the trucks and then they started marking the trucks up with hate crime sayings," Jim Pitts, part owner, said.
The company fabricates piping and steel for refineries and powerhouses. It has a diverse staff of skilled workers. Some employees have worked at the company for about 40 years and are shocked by the destruction.
"There's like 14 trucks that are damaged. Windows, every piece of the truck is damaged, windshields, back panels, quarter panels," worker Bill Welsh said.
Police are trying get some clues from the company's surveillance system, but they apparently don't yield much in darkness.
The factory business next door has experienced a rash of window breakings in recent weeks, but nothing of the magnitude of the damage done to East Coast Constructors.
The owners are offering a $500 reward for information that'll lead police to those responsible.
