Black Mold Testing is one of the most common home mold testing requests.

The purpose of air monitoring, or any black mold and toxic test, is to identify the following information: the types of molds present in the environment, the location of the mold and the extent of the mold contamination. Mold air samples and mold air monitoring of any home or business should always be considered if the individuals who are on the property are experiencing health issues, which can possibly be associated with mold and mycotoxin exposure. Air monitoring and air mold testing is also encouraged for mold testing when visible mold growth or evidence of mold contamination is discovered in the ventilation systems. Testing for mold with the use of air sampling will dictate the extent of mold contamination within certain areas of the property. To get most accurate results of the environment, all windows and doors should be closed to the outside and the ventilation system should remain active.


Do you have mold or mildew issues? Is there inactive black mold in your property? Certified Mold Inspections specializes in black mold testing.

All mold testing, whether for black mold, toxic mold or mold can be risky. All mold inspections and testing should be performed by an indoor environmental professional. Sampling methodologies like air mold testing or any mold testing in the home, business, apartment or commercial property should always be conducted when the existence of mold is presented in a particular area of the structure, by a microbial odor, but may not be recognized through a visual mold inspection. When considering conducting mold air sampling, outdoor air mold samples need to be collected to be used as a baseline comparison to the inside mold samples taken. All molds can be considered dangerous even if it is not black mold. It is important to always have a Certified Mold Inspector (CMI) or a Certified Indoor Environmentalist (CIE) perform the mold testing.

The outside baseline mold test or the outdoor mold control air test is very important when assessing whether or not there is an indoor mold issue, such as black mold. When evaluating the results of the air mold samples the following are indications there may be a mold problem:
(a) The outdoor counts are lower than the indoor counts
(b) Certain molds are detected indoors but not present in the outside baseline air mold test


There are several other ways to test for Mold within the indoor environment:

Surface Mold or Swab Mold Testing

When suspect visual mold is observed, a swab mold test will be conducted to test the surface mold. This is collected by swabbing a measured area, utilizing a sterilize swab tip. The mold swab is then transported to the lab in a tightly sealed tube.

Surface Mold Sample or Mold Tape Lift

A mold tape lift sample is conducted by stripping the suspect mold surface with a slide that has a stick adhesive. The mold tape lift sample is then sealed tightly in a bag and transported to the lab.

Bulk Mold Testing

Bulk mold samples are very invasive ways to test for mold growth. They are collected from areas of visible suspect mold growth by removing pieces of the building material. The bulk mold sample is then placed in a zip lock bag and transported to the lab.

Dust Mold Testing

Dust mold sampling is an excellent way to get a very good look at what is happening in the environment over a longer time period. An Environmental Relative Mold Index or ERMI analysis, developed by the EPA, will be conducted to identify a panel of 36 different mold species.

The third party accredited laboratory will analyze the mold samples and identify the types of mold down to the genus level through visual inspection under a microscope. The results of the mold samples are then analyzed by the a Certified Mold Inspectors (CMI) or a Certified Indoor Environmentalists (CIE) and a condition 1,2 or 3 mold condition will be assigned to the environment.

Condition 1 is a normal fungal ecology which is an indoor environment that may have settled spores, fungal fragments or trace of actual growth whose identity, location and quantity are reflective of a normal fungal ecology for a similar indoor environment.

Condition 2 (settled spores) is an indoor environment that is primarily contaminated with settled spores that were dispersed directly or indirectly from a condition 3 area, and which may have traces of actual growth.

Condition 3 (actual growth) is an indoor environment that is contaminated with the presence of actual mold growth and associated spores. Actual growth includes growth that is active or dormant, visible or hidden.
