While we're killing time waiting on the season to start, anyone had any experience with Starkville Servpro (or in general) or Tupelo Absolute for such? I'm the guy with the vent mold problem and while I wait on the A/C guys (no surprise they are hard to get this time of year) to help with figuring out the root cause I need to clean up the existing mess. Do these type guys really "work"?
