To Test, or Not to Test? That is the Question Part 2
Last week we talked about when you should test for mold. This week we thought it might be interesting to go into a little more detail. Mold testing is interesting in itself and is an important tool to keep a healthy home. There are three types of mold testing methods; Air sample, Bio-tape sample, and Swab samples. This week we want to talk about Air Samples.
Moisture intrusion, water damage, combined with cellulose like wood or paper, fuel mold growth.
Taking air samples during a mold inspection is important because mold spores are not visible to the naked eye. Air samples give good evidence of how many mold spores are around and determine how severe the problem is compared to the outside air which is the control.
The inside of the house should always have a lower mold spore count than the outside. Otherwise you have a problem.
After remediation we take two samples. One inside the house and one outside to act as a control. Samples are sent to the lab before and after the remediation.
We take air samples using a linear pump with an integrated flow meter. The collection device is positioned 3 to 6 feet off the ground. Depending on the situation the test takes between 5 and 10 minutes.
While the sample is being collected, windows and exterior doors should be kept shut.
It is helpful to think of air sampling as just one tool in the tool belt when inspecting a house for mold problems. Air samples are good for use as a background screen to ensure that there isn’t a large source of mold not yet found somewhere in a home.
To prevent mold growing in the first place, vacuum, keep the moisture level in the house under 45% and change the HVAC filters to keep allergens and mold spores low.
Remember keeping mold at bay helps makes you, your family and your house a healthier place to live.
