When it comes to mold, most people think about health concerns, property damage, and expensive repairs. We’re here to make the case that traditional mold testing can mean missed contamination and unresolved problems, creating a lingering risk for homeowners. As the industry moves forward, traditional mold testing methods are becoming inadequate.

In this blog, we’ll explore why conventional methods for mold testing aren’t sufficient and the exciting solutions that cutting-edge technologies offer.

Traditional Mold Testing: The Basics

The most common mold testing method used today is spore trap sampling, often conducted with cassette-based air sampling. This method involves pulling air through a cassette to capture airborne mold spores, which are then analyzed in a lab. It’s been the go-to process for decades, but it has critical limitations.

Similarly, surface sampling (like tape or swab tests) is used to detect visible mold on surfaces. While this method can confirm if mold is present, it cannot tell you the extent of the contamination.

1. Limited Coverage of the Home

Many traditional mold tests focus on just a few rooms of a house, usually the areas where visible mold is present or where moisture issues have been reported. But mold is notorious for spreading invisibly through walls, ventilation systems, and attics. Testing only one or two areas means you are likely missing mold in other parts of the home.

Whole-home testing is essential. Advanced technologies, employed by IET, allow for a comprehensive sweep of every room in the property, ensuring no hidden mold goes unnoticed. Airborne spores can travel throughout the entire home, and every room needs to be tested to capture an accurate picture.

2. Lack of Real-Time Data

Traditional methods often require lab results to come back days, or even weeks after the sample is taken. Homeowners and contractors need quick answers, not delays.

IET’s advanced mold testing technologies offer real-time results for the level of contamination. Instant feedback allows contractors and homeowners to take immediate action, addressing mold issues before they escalate.

3. Surface Tests Don’t Tell a Complete Story

While surface testing can confirm the presence of mold on a wall or ceiling, it can’t reveal what’s lurking behind it or if the mold has spread through the air. Mold behind walls or in a ventilation system could be missed entirely.

Note: This is not to say that each test doesn’t have its place in a well-organized IAQ plan. Some situations would even benefit from the use of our technology coupled with the cassette method, like if you have a known allergy. Cassette testing allows us to identify strains of mold present, if captured.

The Impact of Missed Mold

When mold goes undetected, it continues to grow and can cause long-term damage to the structure of the home. Worse, it can lead to health problems for anyone living in the home, including respiratory issues, allergic reactions, and chronic conditions. If you’re a homeowner, contractor, or real estate professional, missing mold can mean liability, health risks, and significant financial costs down the road.

How the Latest Mold Testing Technologies Make a Difference

New, innovative technologies are addressing the shortcomings of traditional mold testing. Here’s how:

Whole-Home Sampling: Testing every room, not just a select few, ensures that no mold is left undetected. Mold doesn’t stay confined to one area, and neither should your testing.

Instant Reports: No more waiting days for lab results. Instant feedback means you can take action as soon as the mold is confirmed.

Cost: Traditional methods are cost prohibitive, so many times one or two rooms are tested to determine if mold is present within the whole structure. This is not always accurate and you may miss something. With our technology, IET is usually able to scan an entire home, accurately assessing the extent of the mold infestation, for the same amount that others charge for one or two rooms.

Why Homeowners, Contractors, and Real Estate Professionals Should Care

Traditional mold testing methods are simply not good enough when you stack them against the latest technology. With airborne spores that travel through ventilation systems, mold that hides behind walls, and the health risks involved, you need more than just a room test and delayed results. Using the old testing methods can leave you with lingering concerns and incomplete answers. If you’re a contractor or real estate professional, ensuring that a property is free of mold can protect your reputation, keep your clients happy, and prevent future headaches.
