Q: When is mold testing necessary to perform?

Mold testing is most often necessary in cases where there are no visible or obvious signs of mold growth, or to validate that an area has been successfully decontaminated. Other circumstances that make mold testing necessary is for court cases where third-party proof is required to support one’s argument, or when a physician may suspect mold in the home or office as being the culprit behind an illness.

Q: How long does mold testing take?

As there are various types of mold tests that can be performed, times for each to be complete will vary. Typically, testing for mold in a residential home can take as little as 5 minutes, or be as extensive as 1-2 hours. Depending on the type of test conducted, turnaround times will also vary. There are some mold tests that are relatively instantaneous, some that can have laboratory analyses completed within a few hours, and others that may take a few weeks due to incubation periods (i.e., viable mold testing).

Understanding Mold: Risks and Prevention

Mold in your home isn’t just an aesthetic issue—it’s a health hazard. Prolonged exposure to mold can lead to a range of health problems, from mild allergic reactions like sneezing and itchy eyes to more serious conditions such as asthma exacerbation and respiratory infections. The key to protecting your health is not just removing mold, but understanding its causes and how to prevent its growth.

Causes of Mold Growth:

Moisture: The primary culprit behind mold growth. Whether it’s from leaky pipes, flooding, or high humidity, mold thrives in damp environments
Lack of Ventilation: Poorly ventilated spaces trap moisture, creating the perfect breeding ground for mold
Organic Material: Mold needs food to grow, and it finds plenty in homes, feeding on wood, drywall, and other organic materials

Prevention Tips:

Control Humidity: Keep indoor humidity levels between 30-50% to inhibit mold growth
Improve Ventilation Ensure adequate ventilation in high-moisture areas like bathrooms and kitchens. Use exhaust fans to help remove moisture
Fix Leaks: Regularly inspect your home for leaks and address them promptly to prevent moisture accumulation
Clean and Dry: Clean and dry any areas affected by water damage within 24-48 hours to prevent mold spores from taking hold

Understanding the risks and taking proactive steps towards prevention can safeguard your home against mold and the health issues it brings.

Why Test Your Home for Mold?

Professional mold testing has several purposes. One of the most common reasons people decide to get a mold test is persistent odors and visible discoloration on walls and other surfaces. Others experience sudden symptoms such as coughing, sneezing, and headaches.

There are many different kinds of mold–black, white, orange, pink, green, etc. It’s extremely difficult to identify just by looking at it. The best way to find out if you have a mold problem is to get a professional mold test.

Getting your home tested for mold will give you important information about the health of your indoor environment. You’ll be able to:

Assess fungal ecology
Confirm the presence of mold
Identify the types of mold present (including black mold)
Locate the source(s) of moisture
Evaluate the extent of the contamination
Assess health risks
Plan a mold remediation
Provide evidence for insurance claims/litigation
Pass clearance testing (to verify job completion)

I already know I have mold. I don’t need a mold test.

Even if you’re sure that you have a mold problem, a mold test will help guide your mold remediation strategy. If you’re hiring a professional mold removal company to do the work, the technicians will use the test results to plan the scope of work and determine appropriate protective measures.

Mold testing can also come in handy when you’re buying a home and want to ensure no hidden mold problems. Standard home inspections typically do not include any testing or analysis for mold. Furthermore, home inspectors are not required to have any mold training or certification. They can easily overlook subtle signs of mold that a certified mold inspector will easily catch.

With an air test for mold, you’ll also find out exactly what type of mold is growing in your home and how bad the contamination is.

The Environmental Relative Moldiness Index

The Environmental Relative Moldiness Index (ERMI) is an indoor air quality testing method developed by the U.S. Environmental Protection Agency (EPA) together with the U.S.

How Does Mold Testing Work?

Mold detection is a broad term that encompasses a physical mold test and the entire process of inspecting for mold. Often this includes a visual inspection of the area or a thermal imaging scan. The mold inspector will look for potential sources of moisture in your homes, such as damaged plumbing and leaking roofs. Basements and crawlspaces are also equally susceptible to moisture buildup and standing water.

During this process, the mold inspector may take a mold test if the situation calls for it. For example:

If there is an odour present in the room but no visible mold growth
If the inspector finds a discolored material and wants to confirm it’s mold
If water damage is uncovered and the indoor air quality needs to be checked

Maintaining healthy indoor air quality

Some homeowners opt to monitor the air quality inside their homes regularly to prevent mold from becoming a major threat. In this case, mold testing is the perfect tool because it’s fast, easy, and gives you an accurate picture of your home’s indoor air quality.

Do mold test kits work?

Unless you are an indoor environmental professional, you should avoid direct contact with mold. Period. DIY mold testing can release potentially toxic mold spores into your air. Not to mention putting yourself at risk of exposure.

In addition, samples collected using at-home mold test kits are often not handled properly, cross-contaminated, and unreliable.

Finally, professional mold services don’t focus just on the testing mold but also on addressing its causes. Your DIY kit may reveal a problem, but it will not tell you the safest and most effective way to get rid of it.

Surface Sampling

The purpose of mold surface sampling is to determine whether or not a suspected surface (visible black spots, water stain, discoloration, etc.) is contaminated with mold—not to assess indoor air quality. Read more: Surface Sampling.
