When to Call for Mold Remediation (and When an Inspection After Water Damage Makes Sense)
A plain checklist for Houma and Thibodaux property owners deciding whether to handle mold themselves or call a professional.
When should you call for mold remediation?
Call a professional when growth covers more than about 10 square feet, when water sat for more than 24 to 48 hours, when the water was dirty, when a musty smell keeps coming back, or when someone in the home is at higher risk. Those are the cases where hidden growth and health concerns are most likely.
The rest of this guide explains each sign, plus what to do while you wait.
How big is the growth?
Size matters because larger areas usually mean the moisture problem is bigger than it looks. The U.S. EPA suggests that areas larger than about 10 square feet (about a 3 ft by 3 ft patch) are a job for a professional.
Even a small spot can be the visible tip of growth inside a wall, under flooring or behind cabinets, so look for staining, peeling paint, warped baseboards or soft drywall nearby.
How long did the water sit?
If wet drywall, carpet, insulation or wood stayed wet longer than 24 to 48 hours, ask for an inspection. That is the window the EPA gives for drying materials to help prevent mold.
This is why a mold inspection after water damage is often worth it even when nothing is visible yet. Slow leaks, roof leaks after storms and flooded crawl spaces are common in Terrebonne and Lafourche because water can sit unnoticed for days.

Was the water clean or dirty?
Floodwater, sewage backups and water that sat long enough to smell are treated as contaminated. Porous materials touched by that water often need to be removed, not just dried, and cleanup needs protective gear. See sewage & contaminated-water cleanup.
Is there a musty smell with no visible mold?
A persistent earthy or musty smell often points to hidden growth. Note where it is strongest and whether it gets worse when the AC runs, after rain, or in closed rooms. A musty odor investigation or inspection can help find the source.
Is anyone in the home at higher risk?
The CDC notes that people with asthma, allergies, weakened immune systems or chronic lung disease can react more strongly to mold. Infants, older adults and pregnant people are also worth extra caution. If that describes anyone in the home, lean toward calling a professional and talk to a doctor about symptoms.

What should you do while you wait?
- Stop the water source if you can do so safely
- Photograph everything before moving or discarding items
- Run AC or dehumidifiers and keep air moving if materials are only damp
- Avoid disturbing visible growth, which can spread spores
- Do not paint over mold or close up wet walls
- Call your insurer early; see our insurance guide
Questions
Should I get a mold inspection after water damage?
Yes, if materials stayed wet for more than a day or two, if water came from outside or a sewage line, or if you notice a musty smell afterward. An inspection can find hidden moisture before it turns into a larger problem.
Can I clean a small spot of mold myself?
The U.S. EPA says homeowners can often handle a small area (less than about 10 square feet) if the water problem is fixed and no one in the home is at higher risk. Larger areas, hidden growth or contaminated water call for a professional.
How fast does mold start after a leak?
The EPA advises drying wet materials within 24 to 48 hours to help prevent mold growth. After that, the risk rises.
