By Super Green Environmental — Licensed Mold Assessor #MRSA2418, serving Broward, Miami-Dade, and Palm Beach counties
Quick answer: A licensed Florida mold assessor is trained to check moisture levels, HVAC performance, and visible/hidden mold growth in every room of a property — not just the room you’re worried about. Below is what we actually look for, room by room, and why each one matters.
Why Licensing Matters Here
Under Florida Statute 468, anyone performing a mold assessment for pay must hold a state Mold Assessor license, and that license carries a legal obligation: the assessor cannot also perform or profit from remediation on the same property. That’s not a minor technicality — it’s the difference between an inspector who benefits from finding a problem and one who has no reason to exaggerate (or downplay) what they find. You can verify any assessor’s license on the state’s MyFloridaLicense.com. Every finding in this article reflects what a licensed assessor is trained and required to document, not a sales pitch dressed up as an inspection.
Kitchen
- Under the sink — the single most common spot for a slow, unnoticed leak. We check the supply lines, P-trap, and cabinet floor for staining, softness, or a musty smell.
- Behind and under the refrigerator — ice maker lines fail quietly and often go unnoticed for months.
- Around the dishwasher — connection points and the flooring beneath it.
- Ceiling below any second-floor bathroom — a slow upstairs leak often shows up as a kitchen ceiling stain first.
Bathrooms
- Around the tub and shower surround — grout and caulk failures let water behind tile, where it’s invisible until the damage is extensive.
- Behind the toilet and under the vanity — supply line and wax ring leaks.
- Exhaust fan housing — a fan that’s underpowered or rarely used lets humidity sit in the room after every shower, which is one of the most common causes of ceiling mold in Florida bathrooms.
- Window sills, if the bathroom has a window — condensation collects here constantly in humid climates.
HVAC System and Ductwork
This is the one homeowners overlook most, and it’s often the actual source when mold shows up in multiple rooms. We check:
- The drain pan and condensate line for clogs or improper slope — a backed-up line means water sitting inside your air handler.
- Ductwork for condensation, especially in unconditioned attic spaces where a poorly insulated duct can sweat continuously.
- Coil and blower compartment, when accessible, since a system that’s been running with excess moisture can grow mold that then gets circulated through every vent in the house.
Attic and Roofline
- Roof deck and rafters for staining from past or active leaks.
- Ventilation — inadequate attic ventilation traps heat and humidity, which over time promotes mold growth on wood framing even without a leak.
- Insulation for water staining or compression, both signs of past moisture intrusion.
Closets and Low-Airflow Rooms
Any small, enclosed space with limited air circulation is a candidate for elevated humidity, especially closets on exterior walls or above garages. We check for a musty smell, visible spotting on stored fabric or cardboard, and wall moisture readings.
Windows, Doors, and Exterior Walls
Seal failures around windows and doors let humid outside air migrate into wall cavities. We check sills, frames, and the drywall immediately surrounding each opening, since staining here often signals moisture intrusion happening inside the wall, not just on the surface.
Any Area With a Known Water History
If a property has had a prior leak, storm damage, or an insurance claim, that area gets extra attention regardless of whether it looks dry today. Mold can establish behind drywall or under flooring weeks after the original water event, long after the surface looks fine.
What We Document at Every Stop
For each area, a licensed assessor records:
- Moisture meter readings, not just a visual impression
- Visible growth, if any — location, extent, and likely cause
- Whether an air or surface sample is warranted based on what the walkthrough and moisture readings show
That documentation is what separates a licensed assessment from a walkthrough opinion — it’s admissible to insurers, landlords, buyers, and remediation contractors specifically because it’s methodical and independently verifiable.
Frequently Asked Questions
Does every room get an air sample? No. Air sampling is targeted to areas where the walkthrough or moisture readings indicate an actual concern, not applied blanket-wide. A typical assessment includes three to five indoor samples plus one outdoor control sample for comparison.
What if I only have a concern in one room — do you still check the whole property? Yes. Mold problems frequently start somewhere other than where they become visible, so a full walkthrough is standard even for a single-room complaint.
Can a licensed assessor also fix the mold once they find it? No — and that’s by design. Florida law prohibits an assessor’s company from remediating a property it assessed within the previous 12 months. Super Green Environmental never performs remediation, so our findings are never shaped by an incentive to sell you removal work.
How is this different from what a home inspector checks during a real estate inspection? General home inspectors note visible red flags but aren’t licensed to perform mold-specific moisture mapping or air sampling. If a home inspector flags a concern, a licensed mold assessment is the next step to get a documented answer.
