Difference between mold tester and mold contractors:

Some think that mold testers and mold contractors are the same, but they are very different. Mold testing is a non-invasive way of examining the home for possible mold infestation. The purpose of this procedure is to determine how much mold is in the air of the home and whether or not the level is safe for the occupants. There are many mold testing kits sold on the market, but homeowners are discouraged from doing mold testing.

Only the testing kits used by professionals give accurate results. Meanwhile, mold contractors are those that locate and identify the kind of mold present in the home. They do the inspection, find the source of mold and provide a suggested course of action.
