| Storm | Date | What was measured in LaPlace |
|---|---|---|
| Hurricane Isaac | Aug 29, 2012 | Lake surge flooding on the west side of Lake Pontchartrain; USGS high-water marks showed maximum water depths of 1 to 3 feet (National Hurricane Center) |
| Hurricane Ida | Aug 29, 2021 | Highest measured mark 8.2 feet above ground; a LaPlace weather station recorded 99 mph sustained winds (National Hurricane Center and National Weather Service) |
Both storms arrived on the same date, nine years apart. Isaac was slow-moving, which prolonged the surge and rain. Ida brought deeper water plus wind damage and long power outages. Some local accounts say about 5,000 LaPlace houses were damaged by flooding in Isaac alone, though that number comes from secondary sources.
Mostly owners, mostly single-family
LaPlace is a census-designated place, so the Census Bureau publishes no yearly estimate for it. The American Community Survey 2020–2024 counts 28,343 residents and shows:
- 77.5% of occupied homes are owner-occupied, the highest share of any town on this site.
- 82.5% are single detached houses, and 5.4% are mobile homes.
- The median home was built in 1985; 21.9% went up in the 2000s.
St. John the Baptist Parish has lost 6.1% of its population since 2020 (Census Bureau 2025 estimate). After a flood, the homeowner usually carries both the flood claim and the remediation decision. That makes flood insurance (NFIP) questions central here.
After the next flood: an order that protects your claim
Document
Photograph and video everything before tear-out. Keep samples of flooring and drywall if your adjuster asks.
Call the adjuster
FEMA says NFIP policyholders should talk to their adjuster before signing a cleaning or remediation contract, and must take steps to limit mold.
Dry fast
EPA says to dry water-damaged areas within 24 to 48 hours. Open up, pull wet carpet, and run fans if you have power.

Compare scope, price and the company's LSLBC license. Combined water damage and mold work runs $2,700 to $10,000 nationally (Fixr, Aug 2025).
Flood damage goes to your flood (NFIP) policy; wind, roof and plumbing damage usually goes to your homeowners policy. Mold coverage depends on the cause and your policy's mold limits. Full price ranges are in the cost guide.
After a storm, watch for these
Verify the LSLBC license. Get a written contract. Avoid large upfront payments, and never pay in cash, gift cards, wire or crypto (FTC, DOJ and CFPB warning, 2024). Under Louisiana law (R.S. 14:202.1), taking payment and doing no work for 45 days can be residential contractor fraud. Be wary of door-knockers offering free mold inspections.
LaPlace mold questions
My LaPlace home flooded in both Isaac and Ida. Do I need to worry about old mold?
It's worth checking. If wet materials from 2012 or 2021 were left in walls or floors and not fully dried, mold can remain hidden. A musty smell, stains at the old water line, or soft drywall are signs. An independent inspection can help find hidden growth before you renovate or sell. Testing is optional; EPA says it's usually unnecessary when mold is visible.
Do I have to use a licensed company after a flood in LaPlace?
For mold remediation projects of about $7,500 and up, Louisiana requires a Mold Remediation license from the LSLBC, and most whole-house flood jobs cross that line. Owners may do their own work on their own property without a license. Look up any company on the LSLBC website before signing.
Can I cancel a mold contract I signed at my kitchen table after a storm?
Sometimes. Louisiana law (R.S. 9:3538) and the FTC Cooling-Off Rule can give a three-day right to cancel a contract signed at home, but there are exceptions, including emergency work you asked for that has already started. Look for the cancellation notice in your contract and read it closely.
