There’s many different sorts of mold tests from air sampling to surface and bulk lifts, which all depend on the situation of the property being tested. But one thing that’s becoming more and more recurring with a lot of mold testing contractors is testing for mold when visible mold exists. As an example, let’s say a basement has mold on the drywall because the home owner explained there was previous water damage that was never cleaned up, which this example is actually true from a home we just visited. The mold is on all the walls and in some spots three feet high. A competitor of ours goes in and pushes for a mold test because they need to know the type of mold and to see if it’s throughout the house. Now, although it may be in other sections of the home, why would anyone want to sample the air when there is prevalent mold growth in the basement? The reason it shouldn’t be initially tested regardless of what mold inspector will try to sell you to line their pocket, is because the air quality in the basement could in fact effect the air quality on other floors of the home. Hence, the test will be skewed because of the condition of the basement. If there’s mold, there’s no reason to test for mold.
Now we’re all supposed to indicate that all mold is suspect until tested, but when it’s abundantly obvious, then there’s no reason to charge someone for a test to clarify the obvious. And, like I mentioned, the air quality in the basement could in fact effect the sample collected on the next floor. What would the proper method be without trying to charge for services not needed or three times? You remove the mold in the basement, then perform a test not only to assure that the mold in the basement is rectified, but also to check the rest of the home without any influence. Remember, most mold companies use testing as a way to make money and not for service, or to secure that they’re locked into a project, hence the reason for the push. Mold Testing should be a service of clarification and assurance, not something just for profit. So, don’t get oversold with companies trying to push a service on you that isn’t needed because they’ll tell you so. You always have the right to either say, “No,” or “Let me get back to you,” so you can further research your options.
