Meth remeditation

[Mark Ferguson]

Hi, I am looking at a house that had meth smoked in it.  It was not a lab and the results came back at under 5% or .05 in each room.  The problem is the furnace tested the highest which means it was sent throughout the home.  It is a ranch with a finished basement.  2800 total sqft.  Anyone have an idea of what would need to be done?  The agent said a remediation company could do a chemical wash on the walls, and repaint because the results were not too high.  Obviously floor coverings and probably a new furnace.  What about the ducting?  

I have sold REOs that were meth houses, but they were meth labs and they needed a total gut job.  I have never dealt with a smaller issue, or maybe it is not a smaller issue.
