This article says it was just the facade and thats what it looks like, so that should be easily repaired.
AGAWAM – Fire broke out on the upper external facade of the Midnight Mansion haunted house attraction at Six Flags new England at about 8 p.m. Saturday.
No one was injured, all guests were escorted from the building and the rest of the park continued to operate normally, said Melissa M. Pinkerton, the park’s communications manager.
Firefighters for the Agawam Fire Department remained on the scene until after 9 p.m.
Pinkerton didn’t yet know the cause of the fire Saturday night.
Midnight Mansion is part of the park’s Halloween Fright Fest.
This is the best thing we have at SFNE for Fright Fest, and arguably one of the best flats. No way is the town going to let this ever open again. That was part of the problem with TDK, the fire codes. That stinks.
According to someone on SFNE Online who was there tonight the structure caught fire from someone lighting one of the spider webs and it quickly spread. Not sure the truth to this. And according to Guest Relations it will most likely be up by next weekend, maybe Monday. We'll find out more soon though.
