Fire investigators say the cause of a devastating blaze in Hague last week was accidental.

Valley Ford, one of Hague’s biggest businesses, went up in smoke on Wednesday. The damage was so extensive the entire building will likely have to be demolished. Valley Ford was under renovation at the time of the fire, but the service department was still open.

Investigators say faulty electrical wiring in a wall is to blame for the fire. Meanwhile, the owners of Valley Ford are still trying to line up a temporary location to service vehicles. They say there are a few buildings in Hague to choose from. The sales department remains operating, and the owners say they still plan to rebuild the dealership.
