Quick, low-risk steps
- Stop or identify the moisture source when safe.
- Avoid disturbing a large or hidden affected area.
- Record where and when moisture appears.
- Use Florida's official license lookup to verify professionals.
- Compare containment, removal, cleaning, verification, and rebuilding in quotes.
Moisture Correction
Mold cannot grow without moisture. The first step in any remediation is to find and fix the water source. This could be a leaky pipe, roof damage, high indoor humidity, or flooding. Without correcting the moisture problem, mold will likely return even after thorough cleaning.
A Florida-licensed mold assessor can help identify hidden moisture using tools like moisture meters. They can also recommend steps to dry the area and prevent future growth. Do not attempt to dry large areas yourself if the water is contaminated or the area is extensive.
- Stop active leaks immediately if safe to do so.
- Use dehumidifiers to reduce indoor humidity below 60%.
- Inspect for condensation on windows, pipes, or walls.
- Ensure bathrooms and kitchens have proper ventilation.
- Document moisture issues with photos and notes for your records.
Assessment and Protocol
A mold assessment determines the extent of contamination and the type of mold present. In Florida, only a licensed mold assessor can perform this evaluation. They will inspect the property, possibly take samples, and write a remediation protocol.
The protocol is a detailed plan for the remediator to follow. It outlines containment, removal methods, cleaning procedures, and post-remediation verification criteria. Always ask for a written protocol before work begins.
- Hire a Florida-licensed mold assessor for an independent evaluation.
- The protocol should specify containment levels and PPE requirements.
- Ask if sampling is necessary and what it will reveal.
- Ensure the protocol includes a plan for HVAC isolation if needed.
- Review the protocol with the remediator before signing a contract.
Remediation and Cleaning
Remediation involves containing the mold, removing affected materials, and cleaning surfaces. A Florida-licensed mold remediator must follow the assessment protocol. Containment prevents spores from spreading to clean areas during work.
Cleaning methods vary based on the surface and extent of mold. Non-porous materials can often be cleaned, while porous materials like drywall may need removal. The remediator should use HEPA vacuums and appropriate antimicrobial agents.
- Containment should include plastic sheeting and negative air pressure.
- Removed materials must be bagged and disposed of properly.
- HVAC systems should be isolated to prevent spore spread.
- Content handling includes cleaning or disposing of affected belongings.
- Ask how the remediator will protect unaffected areas of your home.
Post-Remediation Verification and Closeout
After remediation, a post-remediation verification (PRV) confirms the area is clean. In Florida, a licensed mold assessor (not the remediator) should perform this inspection. They check for visible mold, moisture, and may take air or surface samples.
The PRV report documents that mold levels are normal. Only then should rebuilding or renovation begin. Keep all documentation, including the protocol, remediation records, and PRV report, for future reference.
- PRV should be done by an independent licensed assessor.
- The report should compare indoor and outdoor mold levels.
- Do not begin rebuilding until PRV is passed.
- Ask for a written closeout report from the remediator.
- Keep all records for insurance or future property sales.

Common questions
What homeowners ask next
Can I do mold remediation myself?
Small areas (less than about 10 square feet) may be cleaned by homeowners following EPA guidelines. However, if the mold is extensive, in HVAC systems, or caused by contaminated water, hire a licensed professional. Always fix the moisture source first.
How long does mold remediation take?
The time varies based on the size of the affected area, the extent of damage, and the drying time needed. A small job might take a day or two, while a large project could take a week or more. Your remediator should provide a timeline in the scope of work.
Is post-remediation verification required in Florida?
Florida regulations require a mold assessor to perform a post-remediation assessment. This ensures the remediation was successful and the area is safe for occupancy. Always verify the assessor's license before the inspection.
