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 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.


We test for the presence of SARS-CoV-2, the virus causing COVID-19, using various sampling methods as outlined above.

Mold testing has many benefits. It keeps us healthy by finding potential mold issues early and preventing health problems. Detecting mold early makes it easier and cheaper to deal with. Testing also helps us take action to stop mold problems. After cleaning up mold, testing confirms if it was successful.

In industries like real estate, a mold test gives important information for buying decisions. For those worried about indoor air quality, testing provides peace of mind by showing clear information about mold levels. It also helps plan specific cleanup based on the types and amounts of mold.

Additionally, mold testing is important for legal or insurance reasons, showing we’re careful about safety. Professionals should handle testing for accurate results.

Long-term exposure to mold can cause health problems. Common effects include respiratory issues like allergies, sneezing, coughing, and asthma. Mold exposure may also lead to skin irritation and chronic sinusitis. The severity varies based on factors like the type of mold and an individual’s sensitivity.


Yes, if professionals don’t fix the source of moisture, mold can come back after removal. To prevent its return, make sure to repair leaks, improve ventilation, and control humidity.

Regularly check areas prone to mold, and consider using mold-resistant materials. Keep indoor humidity below 60%, and address issues promptly. While no process guarantees 100% elimination, these steps help reduce the risk of mold returning.

 Professional mold inspection by certified inspectors can range from $300 to $1,500, encompassing a thorough property examination, sample collection, and analysis. Laboratory testing fees, often necessary for accurate results, can range from $30 to $150 per sample.

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.

Differentiating toxic molds from others is challenging since toxicity depends on factors like mold strain, individual sensitivity, and exposure levels. One commonly known toxic mold is Stachybotrys chartarum, often black or dark green and associated with water-damaged areas. However, not all molds with similar colors are toxic, and not all toxic molds are dark-colored.

Professional testing, including air quality and surface sampling, can identify specific mold types present. Symptoms like respiratory issues and headaches may indicate exposure to toxic molds, but these symptoms can also result from non-toxic molds. If mold is suspected, consulting with a certified mold inspector is recommended for accurate identification and appropriate remediation guidance.

Professional mold inspectors collect samples and send them to a laboratory. 

From then timing can be estimated based on the date samples were collected and lab returned results.

Measurements of the concentration of mold spores in the air, typically provides quicker results, often within a 2-3 days. However, the exact timeframe can depend on the laboratory’s processing time and the specific testing method used.
