Questions About Drying Out After a Leak: First Steps Before Mold Sets In

What is the first thing I should do if I notice this in my home?

For drying out after a leak, the area should be left alone while you note where it is, whether the surface feels damp, and take a photograph. Then set up a mold inspection, so a trained person can check the moisture behind it. In a home dealing with drying out after a leak, leave suspected growth alone rather than scrubbing or disturbing it, since that can spread spores and make the problem harder to assess.

Should I try to clean a small area myself?

EPA guidance draws the line at about 10 sq ft: small, contained spots are sometimes handled by homeowners, and anything larger is a job for a professional. Rather than attempting it yourself, ask a professional if the area is damp, spreading, or behind a wall or under flooring.

Does Louisiana's climate make this more likely?

A warm, humid climate and frequent heavy rain give indoor moisture plenty of opportunity in Louisiana, especially after storms and flooding. In a home dealing with drying out after a leak, homes close to water deal with heavier ambient moisture.

Your Next Step

If this guide matches what you found at home, the next step is a visit — not a guess. Call and describe what you found, and the visit is arranged from what you describe. The Mold Removal page explains what that service covers, and the mold remediation page explains how the full sequence works when mold has spread to more than one room.

Do not enter flooded rooms while you wait, and if water is leaking, turn off the shut-off valve for that fixture where you can reach it safely from dry ground.

Keep the guides on this site bookmarked: the first guide, the signs guide, and the preparation guide cover the checks worth repeating — after moving in, and after bringing used fixtures home.

Mold help is available across Louisiana. See mold remediation in Robeline, LA for one local example, or find your town on the service areas page.
