Mold inspection and testing in Orlando

When an inspection is worth paying for

• You smell it but can't find it. A musty smell with no visible growth usually means a wall cavity, the AC air handler or ductwork, or under flooring. Finding the source is the job.
• After water got inside a wall or ceiling. A roof leak, an AC condensate overflow, a supply line behind a vanity. The question is how far the water spread.
• Before you buy. A home inspector notes stains and moisture readings. A mold assessor goes further. Buying a house with mold.
• When you want a second opinion on a big quote. An assessor has no stake in the size of the removal job, and Florida law keeps it that way for 12 months.
• To check a finished job. A post-remediation check by an independent assessor tells you whether the work met the scope.

When it isn't

If you can see the mold and you know why it's there (the ceiling under last month's roof leak), the EPA and the Florida Department of Health both say sampling usually isn't needed to decide to clean it up. The state health department doesn't test homes at all, and says air sampling is costly and best left to experienced professionals. There's no federal or Florida standard for an acceptable level of indoor mold, so a lab number on its own doesn't tell you much.

What a licensed assessor does

Florida's definition is specific: a mold assessment is physical sampling and a detailed evaluation of the building's history and an inspection, to work out the origin, identity, location and extent of mold growth larger than 10 square feet. In plain terms, a good assessment visit includes:

1. A walk-through and history. Leaks, storms, AC service, how the house is cooled and how long it sits closed.
2. Moisture readings. A moisture meter on walls, ceilings and baseboards, and often a thermal camera to spot cool, damp areas.
3. Humidity. Indoor relative humidity in several rooms. In Orlando this is often the finding that matters most.
4. Sampling where it answers a question. Air samples indoors and outdoors for comparison, swab or tape samples of suspect growth, sent to a lab.
5. A written report. What was found, where, the likely moisture source, and what should be removed or cleaned.

The inspection that comes with the removal

Some remediation companies offer to "check for mold" as the first step of selling a job. That's a sales visit, and it can be perfectly useful, but it isn't the independent assessment Florida's rules are built around. If a company does a licensed assessment on your house, it can't do the remediation for 12 months. If it wants to do the remediation, what it gave you was an estimate.
