Noise with a side of Loud

They've been searching for the source of a foul smelling odor in the office. The pungent aroma is that of a dead animal although my theory was leaning towards some kind of septic leakages. After they(does it matter who?) cut a hole in the ceiling to check it out, they made more noise closing up the hole they made in the ceiling. Now the industrial strength vacuum is running and I'm blogging.

Ok they're done.

Oh yeah, we still have no clue what's causing the smell.
