Meth Positive!!! Recommendations???

[Bob Foglia]

I'm in the process of selling a house in Denver and managed to get it under contract.

The buyers had it meth tested and it came up positive! This is crazy!!!

I now have to have the entire property tested.

Any recommendations on a reputable company to do the testing?

And if you've been through this yourself, any insights on what to expect would be greatly appreciated.

Thanks in advance.
