Thorough cleanup is the only way to get rid of the health hazards in any structure that has been contaminated by meth. The two choices are: decontamination or demolition. Demolition is the process of removing all contaminated materials form the property including walls, floors, ceilings, cabinets etc., and is a partial decontamination at best, and must be done the right way to be effective: it is also extremely expensive! Most advertised decontamination methods are not totally effective; in fact, when only cleaning is used as part of “decontamination,” some residue is inevitably left behind and actually re-contaminates the structure! Just painting over walls doesn’t work either: it just covers up the problem, and toxins inevitably off gas through the paint contaminating the air once again.
