What is a mold test?
Mold testing is the process of inspecting your home for signs of mold growth, identifying the type of mold spores present, and the extent of mold contamination inside the area being monitored. This process typically begins with a visual inspection, where your mold technician will search for visible areas of mold or areas conducive to mold growth, including areas of dampness or water damage.
We analyze the samples in the lab, find mold, and give a detailed report of their findings. This process allows Neptune to assess and address potential mold issues in their environment, contributing to a healthier indoor space. Through Neptune Mold Solutions, you will get unbiased mold testing, that will help us to properly get rid of mold in your home.

How Much Does Mold Testing Cost?
Mold testing for residential properties by certified mold consultants can range anywhere from $300 to $1,500, including a thorough examination of the property, sample collection, and lab analysis. These numbers are rough estimates and are determined by the company you choose. The rates of each inspector may vary.
Air quality testing, focusing on mold spore concentrations, typically costs between $250 and $1,000. Surface testing, which examines specific areas for mold, may range from $100 to $300 per sample.
Sampling Methods
Air Samples
the process of collecting and analyzing air samples to check for different substances like mold. They help assess air quality, identify contaminants, and understand levels of specific particles or gasses. Air sampling is essential for monitoring the environment and studying the indoor air health of the property.
Air-O-Cell Sampler:
This device catches mold spores from the air by making them stick to a special glass slide through a process called impaction. The particles to the coated glass slide allow for a direct view and capture various particles.
Impaction Samples
These samplers hit airborne particles against a surface using a rotating or sliding mechanism. The particles stick to a solid surface like a dish or plate. They are designed for specific particle sizes and are useful for assessing air quality indoors and outdoors.
Spore Traps
Spore traps function by pulling air through a device with a sticky surface to capture mold spores. The sticky surface holds the spores for analysis. These traps are easy to use and offer a sample over time to assess spore concentrations.
Surface Samples
We collect samples from areas of visible mold growth to test for mold contaminates. These methods include bulk sampling, swabbing, or lifting the visible growth using specialized tape. All samples are analyzed in lab to measure the scope of contamination
Tape Lifts
It works by pressing clear tape onto a surface to collect mold spores or particles, with the tape itself serving as the collection medium. It’s simple, easy to use, and directly samples from the surface.
Swab Samples
It works by rubbing a specialized cotton swab on surfaces to collect mold materials. This method is used on irregular surfaces or areas where tape might not stick well. It also allows targeted sampling of specific areas.
Bulk Samples
We collect pieces of material, such as drywall or carpet, which are then analyzed to check for the presence of mold. The actual bulk material serves as the sample. This method is useful for assessing the extent of mold contamination in larger areas, providing information about the composition and severity of the contamination.
Dust Samples
We collect samples from surfaces or settled areas to analyze mold particles. Methods like vacuuming, swabbing, or using tape capture the dust for analysis. This helps understand the mold spores present in a specific environment, informing about indoor air quality, potential health risks
Vacuum Samples
A specialized vacuum with filters is used to collect dust. This method is efficient for collecting various dust particles, including mold spores, and is useful for helping us understand the overall dust composition in an environment
CIRS Samples
CIRS testing, or Chronic Inflammatory Response Syndrome testing, checks for signs of long-term inflammation caused by exposure to environmental toxins like mold. The testing looks at specific markers to identify potential causes of chronic health problems, helping us tailor personalized protocols for the affected home.
qPCR Samples
qPCR (quantitative polymerase chain reaction) is a testing method used to detect and quantify the presence of mold DNA in a given sample. Mold spores contain DNA, and qPCR specifically amplifies and measures the amount of this DNA to determine the concentration of mold in a sample.
COVID SARS Testing
We test for the presence of SARS-CoV-2, the virus causing COVID-19, using various sampling methods as outlined above.
