Understand mold and moisture — clearly, without the fear.
Straightforward, sourced explanations from an independent assessor. In-depth guides here; quick, snippet-style answers in the Answers hub.
Short answer
Mold is a moisture problem first. These guides explain how inspections work, when testing helps, what Florida's assessor/remediator rules mean, and how humidity, HVAC systems, and storms drive indoor mold — so you can make informed decisions.

Field notes
What a mold assessment does and doesn't include
A mold assessment finds the moisture source, documents growth, and tells you what to fix. Here is what it includes, what it leaves out, and why that matters.
AC condensate drain clogs: a quiet mold cause
A clogged AC condensate drain line spills water into closets and walls for weeks before anyone notices. How to spot it, clear it, and know when it caused mold.
Oversized AC: why your Florida home feels humid
An oversized AC cools fast, shuts off, and never runs long enough to dehumidify. Here is why that leaves Florida homes humid and what actually fixes it.
Air sampling vs surface sampling for mold
Air sampling measures what you are breathing. Surface sampling identifies what is growing on a material. Here is when each one earns its cost.
How to read a mold lab report: spore counts
Your mold lab report makes sense once you know the reading order. Here is what spore counts, the outdoor control, and each genus actually tell you.
Musty smell, no visible mold: how we track it
A musty odor with nothing visible means water is sitting somewhere you cannot see. Here is how a Florida inspector narrows it down without guessing.

Florida mold inspection fundamentals

Mold inspection vs. mold testing
Inspection and testing are not the same thing. Here is what each one does, when testing actually helps, and why sampling alone is not an investigation.

Mold assessor vs. mold remediator: why independence matters
Florida separates the roles of assessing mold and remediating it. Here's what each does, why the distinction protects you, and what 'independent' really means.

How does Florida license mold assessors and remediators?
Florida licenses mold assessors and remediators separately and keeps the roles independent.

How much does a mold inspection cost in Port St. Lucie?
What a mold inspection actually costs on the Treasure Coast and what drives the price. Sterling publishes flat pricing: $400 and $700.

“Black mold”: myths and facts
“Black mold” is a colour, not a species, and colour cannot tell you what an organism is or how urgent it is.
Florida humidity and HVAC-related moisture

Florida humidity and indoor mold
Why Florida's climate keeps indoor moisture high, how humidity and HVAC systems contribute, and practical ways to reduce the conditions mold needs.

What causes HVAC mold in Florida homes, and what should you do?
Florida air conditioners run constantly and pull water out of the air — which is exactly why HVAC systems grow mold.
Moisture and building diagnostics
Prevention and next-step education

What is the mold timeline after hurricane flooding?
After a storm floods a Treasure Coast home, mold can begin within 24–48 hours.

How do you prevent mold in a Florida home?
Mold prevention in Florida comes down to controlling moisture — especially humidity.

What to do in the first 48 hours after water damage
A practical guide to the window that decides whether a water event becomes a mold problem — what to do immediately, what to document, and the mistakes that cost.

Post-remediation verification
Sampling and laboratory interpretation

Are DIY mold test kits worth it, or do you need a professional?
Store-bought mold test kits are cheap and easy — and rarely answer the question that matters.

When is air sampling actually useful?
Air sampling is powerful in some situations and close to meaningless in others.

How to read a mold laboratory report
Spore counts, raw counts, genus names, and 'non-detect' — what each part of a mold lab report means, how the outdoor comparison drives the conclusion, and the red.
