Could your home have meth residue? If so, you and your family could be in danger. You know that methamphetamine can severely damage your health. The good news is that if your home does have meth residue, you can have the residue removed. First, though, you'll need to have your home tested. Don't delay your meth residue testing. The sooner you know your home's status, the sooner you can get proactive with your health.

Invisible Impact

Want a good reason to get methamphetamine testing? Meth residue is completely invisible. You won't be able to smell it, either. While meth residue can stick around for years, you may never know it's there.
