Mold removal and remediation in Orlando, FL

How a Florida mold job runs

Florida licenses mold work, and it keeps the two halves apart. The person who assesses mold for pay needs a mold assessor license. The company that removes it needs a mold remediator license. And whichever company did one half on your house can't do the other half for 12 months. Florida doesn't require you to hire an assessor before remediation, but if you want an independent opinion on how big the job is, that rule is what makes it independent.

In practice most Orlando jobs go one of two ways. A small, obvious job (a closet wall behind a leaking water heater, a bathroom ceiling) goes straight to a remediator, who writes a scope and price. A larger or murkier one (a musty smell with no visible source, a whole AC system, a house after a flood) starts with an assessor, who writes up where the growth is and what caused it, and you take that report to two or three remediators for prices.

What the remediation crew does

1. Containment. Plastic sheeting, and negative air pressure with HEPA filtration on larger jobs, so spores stay in the work area. In a slab house with one central AC, the return and supply vents in the area get sealed so the system doesn't carry spores to every room.
2. Removal. Moldy drywall, baseboards, insulation and carpet pad come out. Porous material with growth in it usually can't be cleaned well enough to keep.
3. Cleaning. Studs, block walls and the slab get scrubbed, sanded where needed, and HEPA vacuumed.
4. Drying. Dehumidifiers and air movers until moisture readings are back to normal. In an Orlando summer that takes the AC running and dehumidifiers, not open windows.
5. Verification. Moisture readings, a visual check, and, if you want it, a post-remediation check by an independent licensed assessor. Rebuild after that, not before.

A mold remediator license doesn't cover work that needs a construction license. Florida's definition says so directly. If the job involves replacing a roof section, plumbing or electrical, that part goes to a licensed contractor for that trade.

Paying twice

The most common mold complaint is the same story told different ways: the mold was removed, the walls were closed up, and a year later it was back. Every version has the same cause. Nobody fixed the water. In Orlando the water is often not a leak at all. It's the air. The airport averages 137 days a year with a dew point of 70°F or more, and a house whose AC is oversized, set high, or off for a month while the owners are away will grow mold on cool surfaces without a single drip. Get the cause written into the scope, and get it fixed, before you pay for removal.

The second complaint is scope. A quote that says "remediate master bedroom closet" with a single price is not a plan. What a fair quote lists.

When you don't need any of this

A patch smaller than 10 square feet, about a 3 by 3 foot area, is outside Florida's license rule, and the EPA says most people can clean it themselves. Homeowners working on their own property are also exempt. How to clean a small patch.
