Open guide →Start with Moisture, Not Mold
Mold cannot grow without moisture. Your first job is to find where water is coming from and stop it. This might be a leaky pipe, a roof leak, or high humidity. Fixing the moisture problem is the only way to keep mold from coming back.
If you can't find the source, or if it's inside a wall or ceiling, you may need a professional to help. Don't open up walls or ceilings yourself—you could spread mold spores and make things worse.
- Look for water stains, damp spots, or musty smells.
- Check under sinks, around windows, and near air conditioning units.
- If you use a dehumidifier, empty it often and clean it regularly.
- Don't just paint over a water stain—fix the leak first.
When to Clean It Yourself
You might be able to clean a small area of mold yourself if it's on a hard surface like tile or glass, and if the water came from a clean source like a faucet. The area should be less than about 10 square feet, roughly the size of a small bath mat.
Always wear gloves, goggles, and an N95 mask. Never mix bleach with other cleaners—it can create dangerous fumes. Open windows for fresh air, but don't use a fan that could blow spores around.
- Use water and detergent to scrub mold off hard surfaces.
- Dry the area completely after cleaning.
- Throw away porous items like ceiling tiles or carpet that are moldy.
- Don't try to clean mold inside your HVAC system yourself.
When to Call a Professional
Some situations are too risky or complex for a homeowner. If the mold covers a large area, is in your heating or cooling system, or came from sewage or floodwater, you need a trained professional. Also, if someone in your home has asthma, allergies, or a weak immune system, it's safer to get help.
In Florida, mold assessors and remediators must be licensed. An assessor inspects and tests, while a remediator does the cleanup. They should not be the same company for the same job, to avoid a conflict of interest.
- Mold in HVAC ducts or units needs professional attention.
- Sewage or floodwater mold is a health hazard—don't touch it.
- If you smell mold but can't see it, an assessor can find hidden moisture.
- Always verify a license at myfloridalicense.com before hiring.
Tools to Help You Decide
We have two private tools on this site to help you think through your situation. The Mold Situation Triage asks simple questions to guide you toward the right next step. The Remediation Scope Comparer helps you understand what should be in a professional's plan.
These tools don't collect your information or give medical or legal advice. They are just checklists to help you ask the right questions and feel more confident about your choices.
- Use the Triage tool if you're not sure what to do first.
- Use the Scope Comparer when reviewing quotes from professionals.
- Both tools are private—nothing you enter is saved or shared.
- Always follow up with a licensed professional for a real inspection.

- Do I have the right safety gear (gloves, goggles, N95 mask)?
- Is anyone in the home having health symptoms?
- Is the mold inside the HVAC system?
- Can I see all the mold, or might it be hidden in walls?
- Have I checked Florida licenses for any professional I might hire?
- Do I understand the difference between an assessor and a remediator?
Common questions
What homeowners ask next
Can I just paint over mold?
No. Painting over mold does not kill it or stop it from growing. The mold will eventually come through the paint. You must clean or remove the mold and fix the moisture problem first.
How do I know if a mold professional is licensed in Florida?
Go to myfloridalicense.com and search for the company or individual. Look for a mold assessor or mold remediator license. Make sure the license is active and matches the work they will do.
Is mold testing always necessary?
Not always. If you can see or smell mold, you know it's there. Testing can help identify hidden mold or confirm cleanup is complete, but it should be done by a licensed assessor who follows a standard protocol.
