Meth Contaminated House- how to estimate repairs?

[Samuel Webb]

I am looking at a house that has been severely discounted due to contamination from meth. I have access to the report, the seller has been up front about it. My question is does anyone know how to go about estimating the costs to remove the contamination? Are there companies that specialize in this? It is obviously difficult to put together an analysis without knowing costs, or even how to find someone who would know. The house is in Colorado. Any advise, or previous experiences would be greatly appreciated. Thanks Sam
