Angella Luyk, owner of Midnight Janitorial, runs a finger along a wooden banister.
"One of the hard things with an old mansion like this is dust," says Luyk, walking up an ornate stairway. "Dust, dust, dust and cobwebs."
And while Luyk says her cleaners have the dust under control, they joke that occasionally they're plagued by something beyond their expertise: ghosts.
"I don't believe in ghosts, but my hair would stand up like it was really somebody there!" laughs employee Jessica Perez, as she cleans a law office in the converted East Avenue mansion.
"When you walk in the day after we've cleaned, it smells clean, it feels clean," owner Luyk says. "And we're ghost hunters - just kidding about that part."
One thing Luyk isn't kidding about: giving people with disabilities a shot at steady employment.
