Did you know that Mold Inspectors are required not only to be Certified, but also carry Insurance for testings? Surprisingly, most people are unaware of this fact. This leads to uninsured and inept mold inspection contractors being trusted to deliver vital test results which could cost you tens of thousands of dollars in the long run. Not having the appropriate data collected by a Certified Mold Inspector is just throwing your money away. We are Certified in Mold Inspection receiving perfect test scores in all categories and are fully insured to carry out any mold testing you may need. We proudly serve the Philadelphia, PA area.

Understanding the various types of inspections when dealing with mold will better assist you in coming to a decision on not only which type of inspection to chose, but also the limitations of each that could effect the results. As of today, there aren’t any protocol’s for contractors to follow when doing a Mold Inspection. This is the reason that too many companies in this business will treat a mold inspection more like a paycheck than a service to identify whether or not a home or business has mold growth. So let’s look into some various types of mold inspection services and show their pros and cons.

Air Sampling

Air Sampling is the use of a Bio-Pump which employs forced air to impact spores onto a collection media or cassette. Samples are generally best taken if visual, non-invasive examination reveals apparent mold growth or conditions that could lead to growth, such as moisture intrusion or water damage. Samples are laboratory tested and analyzed and will identify if mold is present, the type of mold and the spore counts against a control. A control is an outdoor sample taken at the inspection to measure the interior air against the outdoor air as a comparison.


Collection Medias or Cassettes are laboratory tested from accredited firms.
High level of accuracy and detailed mold reports.
Fairly inexpensive against other forms of mold tests.


Limited range or square foot coverage.
Multiple samples are needed for detailed analysis.
Limited to only collecting spores to which are airborne.

Air Sampling is one of the most used forms of Mold Tests in the industry today. But understanding the limitations, especially the fact that sampling has a very limited range, can make your decision in choosing what contractor you hire. Mold inspection contractors not taking controls, or a small number of samples without letting a customer know of the range limitations should be avoided.

Surface Sampling

Surface sampling is a method of sampling a suspect area directly and then submitting that sample to a laboratory for results. Is can determine and identify molds actually growing on the surface sampled, as opposed to the mere presence of mold spores.

Great for sampling visible mold growth.
Can reveal spores prior to becoming airborne.
Fairly inexpensive.

Only for surface contact

Bacterial Swab Analysis

Bacterial Swabs are similar in procedure to other swab testings, but the swab itself isn’t sent to a lab. Rather, a handheld device gives an immediate reading once the swab is placed into the unit after the suspect area has been lifted. This is a great tool for food industry to insure surfaces being used on a daily basis are free from bacteria and employees are keeping up with their industry standard responsibilities.

Immediate Results

Unable to Identify Molds
Unable to Separate Mold From Bacteria
No Lab Results

Dust Sampling

Is a method of determining whether the surface spore population represents a normal population or is skewed, indicating the possibility of mold growth in an area. Marker spores indicative of mold growth may also be noted

Samples are known to show the “History” of what has been in the air
Direct examination may be immediately analyzed.

Can be difficult to interpret
Results reliant on many difficult to control factors

Cavity Sampling

This method is the same as air sampling, but it used to test behind walls or in cavities. A hose is attached directly to the cassette and then inserted into the wall or cavity for direct area testing.

Samples collected allow to see if there is any potential growth in an unfrozen area.
Will determine if mold exists behind a wall where regular air testing might not be able to trap.

Holes made large enough for the hose to fit into will have to be later repaired by a third party company.

The most common indoor molds are Cladosporium, Penicillium, Aspergillus, Alternaria and Stachybotrys Chartarum. Mold risks and health issues are directly attributed to three sources from mold exposure, Inhalation, Dermal Exposure, and Ingestion. If you suspect you are ill due to exposure to mold in a building, you should probably vacate the home or building, at a minimum until the cause and presence of mold are evaluated and removed and seek the necessary medical attention.
