Mold Testing

Before testing for Mold, it is important to know what a Mold Test can and can’t tell you. Mold Testing isn’t regulated therefore there isn’t a traditional pass or fail result.  Mold testing identifies the mold spores present and their quantity. If the mold spores are elevated or unusual, this likely indicates a moisture issue in the home.

There are two types of Mold Testing: Air and Swabs

The Mold Air Test will compare the mold spores inside the home to the mold spores outside the home and let you know if they are elevated.  The different types of mold found and their quantities will also be listed on the report.  

This test is used to help identify hidden moisture issues.

Since this test uses a comparison for results, it is beneficial to consider when you are testing.  Testing during the winter is not recommended.  


The cold weather can kill mold spores outside the home and may cause the interior to appear to be elevated even if it is not.  Customers are also discouraged from testing during or after heavy rains as the this may wash the mold spores out of the exterior air which can also cause the interior to appear to be elevated erroneously.

This test is recommended for individuals with allergies, asthma, and breathing difficulties.  This test is also recommended after a water intrusion into the home and post remediation to ensure the issue has been properly resolved.

Mold Testing Swabs will identify what type of mold is present.  

When you can see what appears to be mold and want confirmation, a swab can be taken of the suspected area.  It will then be sent to the laboratory for analysis.  The laboratory will identify the different types of mold found on the swab.  The results will tell you the mold types, quantities, and if it is usual to find these species inside a home.

If you can see the mold, you can address it.
