55% humidity might not sound like much, but in a Florida home it can be the tipping point where mold becomes a concern.
In a recent moisture investigation, our inspector measured indoor humidity at that threshold. The thermostat was set a bit too low with the fan running constantly, which can keep moisture circulating instead of letting the AC remove it. Keeping your thermostat around 78–79° with the fan on Auto helps control humidity, but if readings stay high, it may indicate hidden moisture behind walls or under flooring.
A professional mold assessment can help with:
✔ Humidity and moisture readings throughout the home
✔ Lab-verified mold testing when warranted
✔ Indoor air quality testing for airborne spores
✔ Post-remediation verification (PRV) to confirm cleanup worked
As we head into fall in Fort Pierce, high outdoor humidity and nonstop AC use can reveal hidden moisture issues. Mold Detectives is an independent third-party assessment company—we inspect and test only, never perform cleanup—so your results are unbiased and lab-based.
