After the haunt, for a little extra money, visitors can take a coffin ride.
"It's not really a ride," Harper explains. "More or less it just moves around. It's a buried alive simulator. It's the only one in the state."
Visitors climb into the wooden coffin, which shakes and blows airbursts and various scents at its guest, simulating the person being put into the ground.
Another addition is the Monster Maze, which will have monsters from the Haunted House chasing visitors.
The waiting area of the warehouse will feature live bands and a space to sell T-shirts and souvenirs.
Bowles is handling makeup and making masks for the actors. It takes 35 to 40 volunteers to run the scenes.
"Up until last year we were buying everything off the shelf and having to settle with what another artist had come up with," Bowles said. "So now me and two other guys sculpt and make our own custom [masks].
"This is a hobby for me; it's a good release, almost therapeutic."
The owners hope to use the space for special events other than Halloween -- New Years Eve for instance.
In renting the warehouse, the owners took on $90,000 in debt over three years, Bowles said.
Harper said the move was a big one, but needed, in their quest to have a nationally recognized haunted house.
"We want to be on the Travel Channel -- that's where we want to be," Harper said.
"That's the level we want to be at: To say you have one of the best in the country and be from Charleston, West Virginia, would be an amazing thing.
"I think it'd be a great thing for the city of Charleston and West Virginia."
