What types of mold in homes are actually a concern?

It’s one of the most common questions we hear, especially after a musty smell, visible spots, or water damage.

That’s exactly why we put together this guide, breaking down the most common types of mold found in homes, what they mean, and when it makes sense to get testing:

If you’re looking for a quick answer, here’s what to know:

Some types of mold are of higher concern and typically worth testing:
• Stachybotrys (often called black mold)
• Aspergillus (especially when found in larger amounts indoors)
Others depend more on the situation:
• Penicillium (spreads quickly and often follows water damage)
• Alternaria (commonly found in damp areas like bathrooms or under sinks)
And some are of lower concern but still worth keeping an eye on:
• Cladosporium (can grow on wood, fabrics, and HVAC systems)

Here’s the part most people miss:
It’s not just about the type of mold.
What matters is how much is present, where it’s growing, and what’s causing it.

That’s where testing helps.
A professional mold inspection can:
• Confirm what type of mold is present
• Measure concentration levels
• Identify the moisture source
• Provide clear documentation for next steps

The goal is simple. Give you clear answers so you can move forward with confidence.
