When Hurricane Ida came ashore on August 29, 2021, all power was lost in Jefferson Parish, according to the National Hurricane Center. On the West Bank, water came within a few feet of the top of the levee. For many Marrero homes, the mold that followed likely came from wind and roof damage plus days without air conditioning, not from floodwater. If that matches your house, dry what you can within 24 to 48 hours, as EPA advises, and photograph the damage before anything is torn out.
Marrero homes: older, single-family, owner-occupied
Marrero sits west of the Intracoastal Canal, with Harvey to the east and Westwego to the west. It was once called Amesville and takes its current name from Louis H. Marrero and the Marrero Land Company. Because it is a census-designated place, not a city, there is no yearly Census population estimate. The American Community Survey 2020–2024 counts 32,540 residents.
- Median year built 1972. 69.2% of homes were built before 1980, and 24.9% before 1960.
- 76.8% single detached houses, a higher share than Metairie, Kenner or Gretna.
- 66.1% owner-occupied. Most repair decisions, and insurance calls, fall to the homeowner.
A house built around 1970 has usually had at least one new roof, and often patched plumbing and a replaced AC system. Each of those changes is a spot where water can get in. Attic decking under an old roof leak, the ceiling under an air handler and the wall behind a water heater are common places to start looking. Those are patterns for homes of that age in general, not a survey of Marrero.
How a Marrero mold job usually goes
What a licensed remediation contractor typically does, in order. Details vary by company.
Find the water
Roof leak, AC drain, plumbing or humidity. Removal without fixing the source tends to come back.
Contain the area
Plastic sheeting and negative air keep spores from spreading to the rest of the house.
Remove and clean
Moldy drywall, insulation and carpet usually come out. Framing and decking are cleaned and dried.
Dry and document
You get a written report. Louisiana requires one from a licensed mold remediation contractor.

Before you sign in Marrero
Louisiana requires a Mold Remediation license from the Louisiana State Licensing Board for Contractors (LSLBC) for mold remediation projects of about $7,500 and up (La. R.S. 37:2150.1). Before you sign, look up the company's license on the LSLBC website.
Ask for a written contract with the license number, price and insurance certificates, and avoid large upfront payments. If you also want an inspection, hire a separate company: a Louisiana remediation contractor may not do the mold assessment on the same property.
Typical national ranges, not quotes: attic mold $1,000 to $4,000 (This Old House, Mar 2026); a typical job $1,500 to $9,000 (Fixr, Aug 2025). See the cost guide.
Marrero mold questions
What should I check in a Marrero house after a long power outage?
Start with the places that stay cool and damp: under sinks, behind the refrigerator and washer, closets on outside walls, and the AC closet or air handler. Look up at ceilings for new stains, especially below the roof. If you find growth larger than about 10 square feet, or it is inside the ductwork, get professional quotes.
Is mold from Hurricane Ida roof damage covered by insurance?
It depends. Wind, roof and plumbing damage usually goes to your homeowners policy, and flood damage goes to your flood (NFIP) policy. Mold coverage depends on the cause and your policy's mold limits. Call your insurer before signing a remediation contract, and photograph everything first. No company can promise coverage.
How do I know a Marrero mold company is legitimate?
Look up its license on the LSLBC website before you sign; Louisiana requires a Mold Remediation license for projects of about $7,500 and up. Ask for a written contract with the license number and price, proof of at least $100,000 in liability insurance and workers' comp, and a written report when the work is done.
