- TESTING VS. INSPECTION -
HOW TO DETERMINE IF YOU NEED MOLD TESTING
Mold is an unwanted guest that can creep into your home, often causing health problems and damaging the property itself. Whether you're dealing with a minor infestation or suspecting hidden mold in your home, many people assume mold testing is the first step to determine the extent of the problem.
While mold testing can be a helpful tool in identifying mold issues, it’s important to remember that testing is not always necessary. If mold is clearly visible or you can smell it, the best course of action is a mold inspection to identify and remove the moisture source. Mold testing is often most useful when dealing with hidden mold or health concerns and need to pinpoint the exact nature and extent of the problem.
If you are struggling to determine if mold testing is right for your home, the team at Healthy Air USA has the expertise and experience to help guide you.

TYPES OF MOLD TESTS
AIR TESTING
How it Works:
Air testing involves collecting samples of air to measure the concentration of mold spores floating in your home. The samples are analyzed in a lab to identify the types and levels of mold present in the air.
When to Use It:
Air testing is ideal when you suspect mold but cannot see any visible growth. It's also useful for checking how widespread the mold issue is, as mold spores are often carried by air and can travel far from the source of the infestation.
Pros:
- Detects airborne mold spores.
- Helps determine the extent of the mold problem.
- Useful for identifying hidden mold.
Cons:
- Results are not always accurate, as mold spore levels can fluctuate throughout the day.
- Only provides a snapshot of mold levels at the time of sampling.
SURFACE TESTING
How it Works:
Surface testing involves taking samples from visible mold or surfaces where mold growth is suspected. This can be done using swabs, tape, or other methods that collect mold particles from various surfaces like walls, floors, or furniture.
When to Use It:
Surface testing is useful when you’ve noticed visible mold growth and want to identify the specific types of mold present. It can also be used after cleaning or remediation efforts to ensure that all mold has been removed.
Pros:
- Identifies the types of mold on specific surfaces.
- Provides a clear picture of contamination on visible areas.
Cons:
- Only detects mold in the area where the sample is taken.
- May not indicate the presence of airborne mold or mold in hidden areas.
BULK TESTING
How it Works:
Bulk testing involves collecting a piece of material (like a section of drywall or insulation) from the area where mold is suspected. The sample is then analyzed in a lab to assess the amount and type of mold within the material.
When to Use It:
This method is ideal when you need to know the extent of mold contamination within building materials. It’s often used for severe mold problems where significant damage to the structure is suspected.
Pros:
- Provides a comprehensive analysis of mold growth inside materials.
- Useful for determining the depth of the mold problem.
Cons:
- Requires physical damage to materials (like cutting out a piece of drywall).
- Can be more costly and invasive compared to other tests.
CULTURE TESTING
How it Works:
Culture testing involves taking samples (either air or surface samples) and growing the mold in a lab. This method allows the lab to identify specific species of mold, including those that may not have been detectable through other testing methods.
When to Use It:
Culture testing is often used when you need to know the specific species of mold in your home, especially if you’re concerned about toxigenic molds (those that can produce harmful toxins).
Pros:
- Helps identify specific types of mold, including rare or hidden species.
- Can detect molds that don’t easily show up in other tests.
Cons:
- Takes longer to receive results since the mold needs time to grow.
- May not represent all the molds present in the home, as only certain types can grow in lab conditions.
ERMI TESTING
(ENVIRONMENTAL RELATIVE MOLDINESS INDEX)
How it Works:
ERMI testing involves collecting dust samples from your home and analyzing them using advanced DNA-based technology to identify the types of mold present. The test then calculates a moldiness score, which indicates how moldy your home is compared to a national average.
When to Use It:
ERMI testing is a more advanced, comprehensive method that’s often used by homeowners who want a thorough analysis of their home’s mold problem. It’s especially useful for homes with a history of water damage or health concerns related to mold.
Pros:
- Provides detailed information about the types of molds in your home.
- Can detect both living and non-living mold particles.
Cons:
- More expensive than other mold testing methods.
- Results can be complicated to interpret without expert guidance.

COMMON MISCONCEPTIONS ABOUT MOLD TESTING
People often request mold testing for several reasons, but many of these reasons are misguided:
- To determine if mold is present: Mold is naturally present in indoor environments, and testing will almost always detect some amount. The key issue is whether there is mold growth that could harm health or damage property, and testing might not be able to differentiate.
- To identify specific types of mold: Knowing the exact species of mold isn’t necessary for determining how to address the problem. Any visible mold growth requires removal, regardless of the type.
- To find "toxic" mold: All mold has the potential to produce harmful substances, so distinguishing between “toxic” and “non-toxic” molds isn’t as helpful as many assume.
- To link mold to health issues: Mold tests cannot reliably establish a connection between mold and health complaints, as other factors often contribute to indoor air quality concerns.
Healthy Air USA strongly recommends that instead of rushing to mold testing, homeowners and property managers should start by visually inspecting areas for signs of mold or moisture. Mold growth is often visible, or it can be detected through a musty odor. The primary goal should be to locate the source of moisture and address it directly, as mold will not thrive without water.
Focus on Fixing the Root Cause
In most cases, dealing with mold doesn’t require complex testing. Identifying and fixing moisture problems and removing visible mold will typically resolve the issue more effectively than relying on test results. Mold testing may occasionally be useful, but it should never replace thorough visual inspections and proactive moisture management.
By focusing on prevention and remediation, you can save money and avoid unnecessary tests while protecting your home or workspace from the harmful effects of mold.
