Mold Test Came Back Positive: What to Do Next
A positive mold test means indoor spore levels are elevated above outdoor baselines — but your next step depends on what species were found, how elevated the counts are, and whether the results point to a concealed moisture problem. Here is a step-by-step action plan from positive test to clearance, including what not to do and how long the process takes.

Mold Test Negative but Still Smell Mold: What's Going On?
A negative mold air test doesn't always mean your home is mold-free — it means airborne spores weren't detected at the specific time and location of sampling. Mold can hide behind walls, go dormant, or simply avoid the test area. Here's why results come back clean when your nose says otherwise, what else could cause the smell, and what to do next.

How to Read Mold Test Results: Spore Counts, Species, and What They Mean
Mold test results compare indoor spore counts to outdoor baselines — there is no universal "safe" number. Understanding what species were found, how their concentrations compare to controls, and which patterns suggest a problem is the key to making sense of your report and deciding what to do next.

How to Find a Qualified Mold Inspector (and Why It Can't Be Your Remediation Company)

Home Mold Test Kits: Why They Miss What Matters
Home mold test kits will almost always show mold -- because mold spores are everywhere -- but they can't tell you whether you actually have a problem. Without an outdoor baseline, spore counts, species identification, or moisture assessment, a store-bought kit gives you a result that looks like an answer but doesn't mean what you think it means.

ERMI Testing vs Standard Air Sampling: Which Mold Test Do You Need?
For most residential mold assessments, standard air sampling is the better choice -- it's faster, more affordable, widely accepted by insurers and courts, and directly measures what you're breathing right now. ERMI testing has a specific niche for long-term exposure screening and species-level identification, but it's often oversold as a superior alternative when it's really a different tool for a different question.

Can Mold Testing Be Wrong? False Positives, False Negatives, and Testing Limitations
Yes -- mold testing can be wrong.

Understanding what causes false negatives and false positives helps you get the most reliable picture of your home's air quality.
