| Agency | What it says | Checked |
|---|---|---|
| FEMA (Ready.gov) | "Wet carpeting, furniture, bedding and any other items holding moisture can develop mold within 24 to 48 hours." | Checked: September 2026 |
| EPA | "In most cases, mold will not grow if wet or damp items are dried within 24-48 hours." | Checked: September 2026 |
| CDC | "Clean up and dry out your home fully and quickly (within 24–48 hours) after a flood." | Checked: September 2026 |
How long drying takes in a given house depends on the materials, the type of water and the moisture hidden inside walls and floors. Ask a provider what moisture readings it will take rather than relying on a general number.

When Sewage or Floodwater Was Involved
Mold is only part of the risk when the water was sewage or floodwater. FEMA tells people to keep floodwater-contaminated materials separate and to use protective clothing, and FEMA's Ready.gov flood guidance advises that people with asthma and other lung conditions and/or immune suppression should not enter buildings with indoor water leaks or mold growth that can be seen or smelled.
- A sewer backup or a water line problem outside your walls starts with a call to the Town; see who to call first in Collierville.
- Keep children, pets and anyone without protection away from sewage and floodwater.
- Do not wade into contaminated water.
- A professional assessment is appropriate before anyone starts removing materials that sewage or floodwater touched.

Mold Testing: What Health Agencies Say
Tennessee Department of Health guidance says testing for mold is not recommended, and the department notes there are no national standards for safe mold levels. CDC and EPA guidance is similar. A sensible first step is to fix the moisture problem and deal with visible mold before paying for a test.
- Tennessee Department of Health: testing is not recommended, and the department, CDC and EPA do not test or recommend testing homes for mold.
- CDC does not recommend mold testing, and EPA calls sampling unnecessary in most cases where visible mold growth is present.
- National standards: none exist for what counts as a safe level of mold in a home, according to the Tennessee Department of Health.
- Fixing the moisture problem and dealing with visible mold come before any test.
- If a provider proposes testing anyway, ask what decision the results would change before you agree to pay for it.
Insurance rules that apply once mold is part of a claim are summarized in the Tennessee claim rules in the Collierville guide.
Handling Mold-Contaminated Materials Safely
EPA says unsalvageable mold-contaminated materials should be double-bagged in polyethylene bags at least 6 mil thick. Do not take on work that puts you at risk of mold exposure, or of structural or electrical injury. A restoration provider can take on larger or more contaminated jobs. Keep children and pets out of the affected area.
- EPA: double-bag unsalvageable mold-contaminated materials in polyethylene bags at least 6 mil thick.
- FEMA: keep floodwater-contaminated materials separate and use protective clothing.
- Ask the provider to explain how it plans to handle the mold work in your Collierville home.

License and Permit Questions for Mold Work
Tennessee's Board for Licensing Contractors classification form lists S-Mold Remediation as a specialty classification within a contractor license, and environmental specialties require environmental training certificates. The Town of Collierville also says residential projects that exceed $3,000 need a properly licensed contractor, and the State sets the license type by project cost.
- Contractor license types depend on project cost; the thresholds are in the contractor license rules of the Collierville guide.
- Ask any provider which license the job requires and whether it applies to mold work.
- Permit questions go to the Town's Building & Codes Division at 901-457-2310.
- The Town lists its Building Official at 901-457-2320.
- Ask any provider for proof of insurance and any trade license the job requires, and for an itemized written estimate that shows what each line covers.

Documenting Mold and Talking to Your Insurer
Photographs and receipts help if mold becomes part of a claim. TDCI and the Red Cross both recommend documenting damage, and TDCI advises telling your insurer promptly. How your policy treats mold depends on its wording, so ask the insurer what applies to your loss instead of assuming.
- Photograph and video the source of the water, the wet materials and any visible mold before cleanup, when it is safe.
- Keep receipts for temporary repairs and any provider's estimate.
- Tennessee's insurer response rules (rule 0780-01-05-.08) are summarized in the Tennessee claim rules section of the Collierville guide.
- Standard homeowners policies typically exclude flood and backed-up drains or sewers, according to TDCI guidance; your policy wording controls.

If That Did Not Work
If you cannot tell whether mold is growing, or a provider's answers do not settle it, you still have three exits: try again, try another route, or contact an agency. Ask each provider or office what to do while you wait, and keep the affected area protected and out of use.
- Try again: ask the provider what moisture readings it took and what they show, and ask a second provider that serves your ZIP code for its own assessment.
- Try another route: for people with asthma, lung disease or a suppressed immune system, keep them out of buildings with indoor water leaks or mold growth that can be seen or smelled, as FEMA/Ready.gov guidance advises.
