Mold Remediation in New Orleans, LA

New Orleans Lakefront averages about 60 inches of precipitation a year (NOAA 1991–2020), and about 74% of the city's homes were built before 1980 (Census ACS). Humid air from spring through fall means wet materials do not dry on their own, so most remediation here is a race against time and humidity.

Raised shotguns and Creole cottages

In Uptown, the Irish Channel, Mid-City, and Tremé, many houses stand on piers. Air moves under the floor, but on summer days humid outdoor air meets joists, ducts, and floor insulation cooled by the air conditioning above, and moisture collects on them. Insulation sags, joists darken, and the floor above can smell musty. The crew removes wet insulation, cleans the framing from below, and the moisture plan follows: insulated ducts, a better-sealed floor, or a different insulation approach. Our crawl space mold guide covers the options.

Slab homes after street flooding

In Lakeview, Gentilly, and New Orleans East, homes sit closer to the ground. When a heavy downpour floods the street faster than the drainage system clears it, water can reach flooring and lower walls. Floodwater counts as contaminated, so drywall, insulation, carpet, and pad it touched come out, and the slab and framing are cleaned and dried. See water damage and mold.

Houses closed up after a hurricane

After Hurricane Ida in 2021, all of Orleans Parish lost power. A house shut tight in late-summer heat with no air conditioning can grow mold on walls, furniture, and closets even without a leak. Those jobs are about scale: cleaning surfaces throughout, removing materials that stayed damp, and running dehumidifiers until readings come down.

Doubles and historic homes

In a shotgun double, the other half shares the wall and sometimes the space under the floor, so containment and timing matter. Plaster walls and original trim take more care to protect. Exterior repairs in historic districts may also need review by the Historic District Landmarks Commission.

The Louisiana mold license

Mold remediation worth more than $7,500 must be done by a company holding the Mold Remediation classification from the Louisiana State Licensing Board for Contractors, whose qualifying party has 24 hours of board-approved training. Search the LSLBC database and ask for that classification by name. From August 1, 2026, licensees must carry at least $500,000 in liability insurance. A scope based on an independent mold inspection in New Orleans helps you compare bids.

Price

We have not found a New Orleans price survey we trust; HomeGuide's national figure of about $1,100 to $3,400 for a typical job is the reference. Whole-house cleanups after an outage and slab homes that took water cost more. See the remediation cost guide, and mold testing in New Orleans for the check afterward.

When you call

Say whether the house is raised or on a slab, whether water came in or the house sat closed without power, and where the mold is. The local company on the line explains the next step and the price, and the call costs nothing.

Louisiana licenses mold remediation: jobs over $7,500 need the LSLBC Mold Remediation classification, with 24 hours of training and, from August 1, 2026, $500,000 in liability insurance. Look it up by name in the LSLBC search.
