Wet materials should be dried within 24 to 48 hours, as EPA mold guidance recommends, to keep mold from taking hold. No Wisconsin state licence for mold inspection or remediation was found. Confirm the rules with the Wisconsin Department of Health Services, and call (833) 490-5225 as soon as the water is found.
Key takeaways
- EPA mold guidance treats 24 to 48 hours as the window to dry wet materials.
- No state licence for mold inspection or remediation was found for Wisconsin.
- Porous materials that stayed wet longer than that are usually better removed than saved.
- Industry standards such as the ANSI/IICRC S500 and S520 describe the work; they are not a state licence.
How long can wet materials sit before mold becomes a problem?
Dry wet materials within 24 to 48 hours. After that, mold can start, and porous materials are usually removed.
The drying time depends on the material and the moisture readings on the framing. A surface that looks dry can still hold water in the framing behind it.
A technician measures the framing and reports the readings, so the decision about what to keep is based on numbers.
What rules apply to mold work in Wisconsin?
No state licence for mold inspection or remediation was found. Confirm with the Wisconsin Department of Health Services.
Secondary sources report that Wisconsin considered mold legislation, but the outcome was not confirmed, so this page does not state a rule that may not apply.
Never assume a mold problem is either harmless or dangerous without an inspection. Ask for the readings and the plan in writing.
Frequently asked questions
Is a mold smell after a flood always a problem?
It is a sign that material is still damp. A technician will measure the framing and recommend what to remove and what to dry.
Do I need a state-licensed mold company?
