If you see mould there is no reason to test. Knowing the “name” of the various species of mould (there are always many growing together) is of very little value. A Professional Restoration Company will remediate mould from homes the Best Way, Every Time, regardless of whatever types are involved. This means they take full safety precautions Every Time – thereby insuring the full safety of both their workers and all occupants of the structure! If you do not see mould but think there might be some, hidden away, contact your local PuroClean for advice. Many times they will recommend that you bring in a Certified Indoor Hygienist who has the training, skills and expertise to test your home with several testing systems to determine the presence of unusual amounts of mould. Remember, mould spores are always in your home – it is Growing and Living mould that presents the concern with allergens and mycotoxins.
