Asbestos Testing FAQs
When Was Asbestos Banned?
Asbestos was never fully banned in the United States. While its use has been heavily regulated since the 1970s, certain products may still legally contain asbestos. This is why it’s critical to remain diligent, especially when working in or renovating older buildings where asbestos-containing materials may still be present.
If you suspect asbestos, testing is the best way to confirm its presence.
Where is asbestos commonly found?
Asbestos can be anywhere! But in Michigan it is commonly found in older insulation (Vermiculite), tiles (particularly 9x9 floor tiles) , roofing, and cement products, especially in homes built before the 1980s.
How can I tell if my home has asbestos?
There is no way to identify asbestos containing materials on your own. The only way to confirm asbestos is through professional testing of suspect materials. This is why it’s so vital to test before you renovate!
Why is asbestos harmful?
Inhaling asbestos fibers can lead to health problems like asbestosis, lung cancer, and mesothelioma.
Can I test for asbestos myself?
DIY asbestos testing can be risky and lead to inaccurate results or exposure to harmful fibers. ETL recommends using certified professionals for safe and reliable sample collection and analysis.
What should I do if asbestos is found?
If you suspect asbestos, avoid disturbing the material unnecessarily. For non-friable materials (like floor tiles or siding), it may be possible to take a sample yourself following strict safety guidelines. However, for friable or easily damaged materials, we recommend contacting a certified professional to ensure safe handling.
ETL offers expert analysis for asbestos samples, whether collected by you or a professional. If you’re unsure about how to proceed, contact us for guidance!
Can Asbestos Be in Homes Built After 1980?
Yes, asbestos-containing materials were still used in construction well into the 1990s and, in some cases, even later. While regulations reduced its prevalence, asbestos has never been fully banned in the U.S., and some materials may still legally contain it.
Is It Safe to Live with Undisturbed Asbestos?
Undisturbed asbestos poses less risk, as the fibers are not easily released into the air. However, it’s important to monitor the material’s condition over time, especially if you’re planning renovations or activities that could disturb it.
What’s the Difference Between Friable and Non-Friable Asbestos?
Friable asbestos easily crumbles under hand pressure, releasing harmful fibers into the air, making it more hazardous. Non-friable asbestos, on the other hand, is more stable and less likely to release fibers unless it is cut, broken, or otherwise damaged.
What Should I Do If I Suspect Asbestos in a Product?
Avoid disturbing the material to minimize the risk of fiber release. For non-friable materials, you may be able to collect a sample yourself following safety guidelines, but for friable or damaged materials, contact a certified professional for inspection and testing.
Mold Testing FAQs
What Are the Signs of Mold in a House?
Common signs of mold in a home include musty odors, visible spots of discoloration on walls or ceilings, signs of water damage, and increased indoor humidity. These indicators often point to the presence of mold, even if it’s not immediately visible. Don’t ignore these signs, as untreated mold can spread quickly and cause structural damage. If you suspect mold, testing can confirm its presence and help determine the next steps.
How Is Mold Testing Done?
Mold testing typically involves collecting surface and air samples to determine the type and level of contamination. Surface samples, often enough for many situations, can be easily collected, and ETL can guide you through this process to ensure accurate results. These samples are analyzed in our lab to identify mold types and help you take the next steps.
For more complex cases, such as when mold may not be visible or air quality is a concern, air sampling may be necessary. Our consulting company, ETC, specializes in this service and can provide professional assessments to detect airborne mold spores and evaluate indoor air quality.
Can Mold Exposure Harm Your Health?
Yes, mold exposure can negatively impact health, particularly for individuals with asthma, allergies, or weakened immune systems. Breathing in mold spores can cause respiratory problems, skin irritation, and allergic reactions. Some molds, like black mold, produce harmful mycotoxins that can pose serious health risks.
When Should I Get Mold Testing?
Mold testing is recommended if you notice visible mold growth, experience persistent health issues like allergies or breathing difficulties, or after water damage. It’s also advisable when purchasing a home or if you detect musty odors.
How Can I Prevent Mold?
Preventing mold involves controlling moisture in your home. Keep indoor humidity levels below 60%, fix leaks promptly, and ensure proper ventilation in damp areas like bathrooms, kitchens, and basements.
Does Bleach Kill Mold?
While bleach can kill surface mold on non-porous materials like tiles, it’s often ineffective on porous surfaces like drywall, wood, or fabrics. Bleach doesn’t penetrate these materials, allowing mold to regrow.
How Fast Does Mold Grow After Water Damage?
Mold can begin to grow within 24 to 48 hours of water exposure. This rapid growth highlights the importance of addressing water damage immediately. Quick cleanup and drying of affected areas can help prevent mold from taking hold. If mold growth has already started, testing can assess the extent of contamination.
Do Different Molds Need Different Treatments?
Yes, different types of mold require specific approaches for effective removal. For example, some molds are more toxic or invasive than others, and they may require advanced containment and remediation techniques. Mold testing identifies the type of mold present, enabling targeted treatment to resolve the issue effectively.
When Is Mold Growth More Likely?
Mold thrives in warm, humid environments and is more likely to grow during humid seasons or in areas with poor ventilation, such as basements and bathrooms. Controlling humidity and ensuring proper airflow can reduce the risk of mold growth in these vulnerable spaces.
Is All Mold That’s Black Considered “Black Mold”?
No, not all black-colored mold is “black mold.” The term typically refers to Stachybotrys chartarum, a specific mold species known for producing harmful mycotoxins. However, many types of mold can appear black or dark in color and may not pose the same health risks.
To determine whether the mold you’ve found is Stachybotrys chartarum or another species, testing is essential. ETL can guide you through collecting surface samples to identify the type of mold present. For more complex situations, ETC, our consulting company, can assist with air sampling and in-depth assessments.
Soot and Ash FAQ's
Why Should I test for Soot and Ash after a wildfire nearby?
Microscopic particles can travel a large distance, and settle in your home, even if you don’t see visible soot or ash. These particles can accumulate in HVAC systems, vents, and porous materials like carpets, curtains, and upholstery.

What is soot and ash testing, and why is it needed?
Soot and ash testing identifies contamination from fires or smoke. It helps assess health risks and property damage and ensures spaces are safe.
How do soot and ash affect air quality?
Soot and ash particles can spread through air and settle on surfaces, causing respiratory problems and contamination. Testing detects these particles and helps insurance adjusters, and remediation firms understand how to clean up properly.
