How Lab Mold Testing Works
(And Why DIY Kits Fall Short for Metro Detroit Homeowners)
If you’re a homeowner in Metro Detroit, whether you’re in Ferndale, Grosse Pointe, Royal Oak, or somewhere in between, you’ve probably encountered that telltale musty smell in a basement or seen a questionable patch of black fuzz in the bathroom. When that happens, it’s natural to wonder: Do I have mold?
Google will show you plenty of DIY mold test kits claiming to offer fast answers at a low price.
Tempting? Sure. But there’s a big difference between peace of mind—and just thinking you’ve solved the problem.
What Is Professional Mold Testing?
Professional mold testing means your sample is collected or reviewed by trained experts and analyzed by a trusted local lab. In Metro Detroit, labs like ours follow State and Federal guidelines to ensure testing is accurate, unbiased, and reliable, especially if documentation is ever needed for a home sale or insurance claim.
These tests often include:
Air sampling to detect invisible spores
Surface sampling for visible mold
Tape lifts or swabs for material ID
Lab analysis to determine species and spore counts
Why DIY Kits Can Be Misleading
DIY kits may seem convenient, but they often:
Lack context: They can’t tell you how much mold is too much for your family.
Aren’t specific: Many kits don’t identify the type of mold.
Miss airborne spores: Most only test surfaces.
Are easily contaminated: False positives are common.
And even most DIY kits still require lab analysis—meaning you’re often paying for results without the benefit of professional help.

The Unique Challenge of Michigan Basements
In Michigan, especially in older homes, many basements are what’s colloquially known as “Michigan basements.” These are former crawl spaces that have been dug out to create a basement area, often with stone walls and dirt floors. While they provide additional space, they are particularly prone to moisture issues due to their construction and lack of modern waterproofing.
Springtime poses a significant challenge for these basements. The combination of melting snow, heavy rains, and saturated soil can lead to water seeping into these spaces. The porous nature of the stone walls and dirt floors allows moisture to enter easily, creating an ideal environment for mold growth. Homeowners with Michigan basements should be especially vigilant during the spring months to monitor for signs of water intrusion and mold development.
When Should Metro Detroit Homeowners Consider Professional Mold Testing?
You should consider mold testing if:
You’ve had recent water damage (basement flooding, burst pipe, roof leak)
You notice mold smells or visible growth
Someone in the household has new respiratory issues
You’re buying or selling a home in Michigan
You need documentation for insurance, landlords, or legal reasons
