Mold Inspection Methods

1

The most common causes of poor indoor air in homes, classroom, and public spaces is dampness.  This is because moisture promotes the growth of molds.  There are no specific guidelines when it comes to testing the presence of molds because it is not a federally regulated contaminant and therefore there is no certainty who will conduct the test and what they will be testing.  Because there are no guidelines, testing for the presence of molds in the home is also confusing since one test may show negative for molds, another may show positive for the presence of molds.

Mold testing is important to some who have respiratory issues and are highly vulnerable to mold spores but there are others who just want to test the air quality in their home for their own peace of mind.  There are companies who are able to provide quality air testing but others are not reputable and this should be a reason for concern to all.

So before hiring a company for mold inspection it is important to make a careful and critical scrutiny of the company.  You have to know where the inspector from this site is focusing his attention when you hire someone to do it.  There are at least two efficacious ways in determining if an actual mold problem exists, but the point that I want to make is which among them is the most adequate.

The two methods of testing differ in the way they get their samples for testing.  The primary types of sample test to determine mold issues in the home involves surface sampling where the inspector must positively identify the presence of mold spore deposits in your home and gather them for further testing.  Evaluating mold level in and out of the home is the most common form.  When the mold testing is completed the mold spore level inside the home will then be compared them with the level outside.  So with the result  of the test the inspector can verify the presence of absence of molds in your home.

Since it is not possible to find more mold spores on surfaces at certain stages, then the second way of finding out is by testing the air.

There are many different air testing types that are being used today.  Spore traps.  This is a controversial but common method used for mold testing.  To collect mold spores, they use a calibrated pump to draw an specified amount of over a greased slide.  This method is an impaction method.  A Petri dish viable sampling is another method used.  Like spore traps, this impaction method places a growing media underneath a pin holed cap and air is drawn over it.
