Decontaminating a Former Meth House
We recommend testing every room in the property first. If they only cooked meth in the basement, and it didn't filter upstairs and the levels upstairs are low, then we can save them on the decontamination because we only have to take care of the basement and not the upstairs. Plus, once the decontamination process is complete, the team only has to retest the areas where levels were above the acceptable limit instead of testing the whole home. If a home needs decontamination, we first have to dispose of everything that cannot be properly decontaminated. We are talking about porous items like carpet, padding, window blinds that may be hard to clean, a range hood or exhaust vents in a bathroom. Sometimes, entire duct systems have to be thrown out too. Some of the flexible ducting gets meth residue trapped, and is difficult to clean. Then you must HEPA vac every square inch of the property. You have to start with a clean surface, then you use a chemical that is designed to breakdown and neutralize the meth chemical residue left behind.
