Generally, you'll want to test for black mold to identify the building's indoor air quality and to avoid experiencing health problems related to black mold. If you are a landlord, you may be required by your local government to adhere to certain standards and subject your property to black mold testing so you can renew your business permit. At times, black mold testing may also become necessary when you are filing for insurance. Insurers will want to make sure that the properties that they are risking money for are actually worth their value.
It may also be that you're planning to sell your house, and would want to get the best price for it. A buyer who, after having your house inspected, finds out that it is teeming with black mold growth would no longer be interested in the purchase even after you make the needed repairs.
A Certified Mold Inspector is well-versed in all aspects of black mold testing and are authorized to give the proper certifications. However, be wary of scams involving mold remediation and removal. An inspection doesn't necessarily have to be tied up with professional mold cleaning.
If you seriously believe that the infestation is minor and that you can manage it by yourself, then by all means, do so. But if you feel that the job should be handled by a professional, make sure that they are legit or that they have the knowledge and experience in getting rid of black mold.
You'll be able to determine their expertise by reading about black mold beforehand. Only then can you ask sensible questions from the team, and if they can answer your questions convincingly, then it should be alright to commit your house's well-being in their hands.
Perhaps the only value in hiring a Certified Mold Inspector is the certification they could provide, again, for purposes such as insurance or for the sale of your home, if the prospective buyer requires it.
But if you don't need a black mold testing certification, it would be better to spend your hard-earned cash on the team of professionals who are actually going to perform the cleaning. Keep in mind that an experienced outfit also have the expertise in searching for the places where black mold growth is highly probable.
More important than the aesthetic value of black mold testing and cleaning is the health of your home and your own health. There are many diseases stemming from black mold contamination, some of them severe. To avoid contracting diseases, it is important for you to completely eradicate any mold growth from your home, because leaving even a tiny bit can start another cycle.
Prior to contacting a certified inspector, you might want to inspect the home yourself. A dead giveaway to the growth is a putrid, earthy smell. If you have a keen sense of smell and can follow the source of the odor, there's a big chance that you might just hit the spot where black mold thrives.
Look for them in humid and moist areas - especially those that are hardly exposed to sunlight. Mold can also grow in rooms that are poorly ventilated, such as basements. Inspect the corners, the walls, and the ceilings. Throw out old magazines, clothes, and furniture that have become waterlogged.
Don't bother yourself with mold levels - there is actually no standard for this. This is also why it may be difficult to make an accurate assessment of Black Mold testing; there is no existing data with which to compare your findings.
