How to Test for the Presence of Mold

Category : Mold Testing

If a homeowner suspects there is mold present in his or her home, there are a variety of ways in which a professional can test for its presence. Quite obviously, the easiest way for a specialist to detect mold in a home is by examining it visually. However, there are a few additional methods that can be used. Let’s examine a few:

Air Testing

In addition to spotting it with his or her own eyes, mold professionals can also test the air in a home. Using special equipment, professionals test for the concentration of mold spores. After samples are taken, they are usually examined under a high-powered microscope. With air testing, it is important to note that results can typically fluctuate on weekly and even daily basis, which is why it may need to be done more than once.

Surface  & Bulk Testing

Surface testing entails swabbing the surfaces in one’s home where mold is suspected to be hiding. Mold specialists usually take multiple samples, covering all areas of one’s home, including the basement and attic, where mold is typically present.

Similarly, bulk testing involves taking larger samples of material from one’s home and testing it in a lab.

Other Indicators 

A rather dead giveaway that mold is present in your home is its stench. Mold typically gives off a noticeably unpleasant odor. If you detect a foul odor in your home but aren’t sure if it’s due to mold, it’s best to get a second opinion from a mold professional.

Test and Test Again

You believe there may be mold in your home so you contact a mold professional for an inspection. The mold professional confirms the presence of mold in your home and takes the necessary steps to remove it. However, a few weeks later, you begin to start suffering from allergies again or detect a familiar smell. Your worst nightmare has become a reality — the mold has returned (for one reason or another).

Just because you remove mold from your home does not mean it will never come back. If necessary, it’s wise to have your mold professional take another look at your home to determine whether the mold has returned. In damp areas like New England, it’s not such a bad idea to have your home tested for mold annually, especially if you or your family suffer from the symptoms it can cause.
