Cost of sorting out meth problems can vary wildly. Where a low level of contamination may be no risk to health and not need anything doing, as a worst case scenario, properties can need to be destroyed.
Costs for detailed testing often range from $3,000 to 10,000
Decontamination $2,000 to $50,000
Then there is cost of reinstatement.
Sorting things out can take months. If it is an existing rental, this can lead to significant problems with loss of rent. Most people should expect to spend between $10,000-$50,000 plus the cost of reinstatement.
