Ceiling Repair in Wyandotte area?

I'm in a 1929 cottage bungalow near Fort Street and Eureka and in one of the rooms on the ground floor, there's a stucco ceiling that's slowly buckling. It was already cracked when I first moved in, but just this month the crack has started to widen and now I'm fearing that it may suddenly collapse. And no, it isn't cracking due to rain runoff [[especially considering that my pump system failed during the events of August 11), since I don't see any water spots on any objects below that part of the ceiling.

So, can anyone recommend me a ceiling repair place in or near Wyandotte?
