You open a cabinet under the sink or pull back a piece of drywall and find something dark and fuzzy where it definitely shouldn’t be. Knowing what to do when you find mold in your home is exactly what this episode covers — calmly, in order, without the panic spiral.
This is Episode 1 of the Mold Remediation Austin Podcast, a four-episode series built for Austin-area homeowners who’ve discovered mold and want clear, honest guidance. By the end of this episode, you’ll have a solid picture of your first 48 hours: what to do immediately, how to assess what you found, and how to decide whether this is something you can handle yourself or something that calls for a professional.
What You’ll Learn
- The single most important thing to do in the first few minutes after finding mold (and why it involves your HVAC)
- Why mold color is not a reliable indicator of danger, and what actually matters instead
- The four questions to ask when assessing what you found: size, location, material, and moisture source
- The EPA guideline for when DIY mold removal is appropriate — and when it isn’t
- How Texas law protects Austin homeowners during the remediation process
- The three questions to ask any mold remediation company before you hire them
Episode Highlights

Stop — before you do anything else. The first few minutes matter. Before you scrub anything or call anyone, there are three things to do: leave the mold undisturbed, turn off your HVAC system, and close off the area. Running your HVAC when mold is present can spread spores through your ductwork into rooms that currently have no problem. It’s one of the most common mistakes homeowners make in the first hour.
What you’re actually looking at. The episode breaks down the four things that actually matter when you’re assessing mold: how big the affected area is, where it’s located in the home, what material it’s growing on, and what the moisture source is. That last one is the most commonly skipped, and it’s the one that determines whether the problem comes back. Mold doesn’t appear from nowhere. Find the water source, or the mold will find its way back.
Your 48-hour plan. The EPA offers a widely cited guideline: if the affected area is smaller than about 10 square feet, roughly a three-by-three-foot patch, it may be appropriate for a careful, healthy adult to handle with the right protective gear. If it’s larger than that, on a porous material, near your air system, or if anyone in the home has respiratory conditions or a compromised immune system, it’s time to call a licensed professional.
The Austin advantage. Texas law requires that mold assessment and mold remediation be performed by separate, independently licensed entities. The same contractor cannot legally do both. What this means in practice: no one who walks through your door to assess the situation has a financial incentive to upsell you on remediation. That’s built into state law, and it’s on your side.
Key Topics Covered
Discovering mold is stressful, but the first 48 hours are more manageable than they feel in the moment. The most important thing you can do right away isn’t cleaning or calling — it’s stopping the conditions that allow the problem to spread. Turning off the HVAC, leaving the mold undisturbed, and closing off the affected area buys you time to assess calmly rather than react in panic.
The widespread fear around “black mold” has been significantly overstated in popular media. Color tells you very little about which mold species you’re dealing with or how serious the situation is. The species most associated with the “toxic black mold” narrative, Stachybotrys chartarum, is just one of hundreds of mold types — and harmful molds come in many colors. What matters is size, location, material, and moisture source. That framework is more useful than color identification and leads to better decisions.
For Austin homeowners specifically, the Texas regulatory environment around mold remediation is worth understanding. The Texas Department of Licensing and Regulation (TDLR) licenses mold assessment and mold remediation separately and prohibits the same company from performing both on the same project. This separation exists to protect homeowners, and knowing about it puts you in a stronger position when evaluating contractors.
