Slidell homes by the numbers
The Census Bureau 2025 estimate puts Slidell at 28,341 residents, down 1.1% since 2020. The American Community Survey 2020–2024 adds the housing picture:
- Median year built 1979, with 33.2% of homes built in the 1970s.
- 15.4% built in the 2000s, likely including rebuilding after Katrina.
- 68.5% owner-occupied and 72.4% single detached houses.
The city sits about 3 miles north of the lake, and Olde Towne is its historic area. With a third of homes built in the 1970s, many houses here are now around 50 years old.
Water from the lake, the sky and the pipes
Slidell's mold story starts with water, and it has arrived in several ways.
| When | Event | Recorded effect |
|---|---|---|
| Aug 2005 | Hurricane Katrina | Surge over 10 feet in parts of the city; 13 to 16 feet in unincorporated areas to the south and east |
| Aug 2012 | Hurricane Isaac | Lake surge inundated parts of Slidell, Lacombe, Mandeville and Madisonville (National Hurricane Center) |
| Mar and Aug 2016 | Severe storms and flooding | Two FEMA disaster declarations for St. Tammany Parish |
| Aug 2021 | Hurricane Ida | Slidell gauge reached 5.3 feet above mean higher high water |
| 2024 | Tornado | Struck the south of the city |
| Jan 2025 | Winter storm | About 7 inches of snow |
Each kind of water leaves a different pattern. Surge and flash flooding wet the lower walls, flooring and anything under a raised floor. Wind and tornado damage open roofs and let rain into attics and ceilings. A freeze can split a pipe inside a wall. When you ask for quotes, say which one you think happened.
Hiring after a storm in St. Tammany
Storm scam warning
- Verify the company's license on the LSLBC website.
- Get a written contract with the license number, price and insurance certificates.
- No large upfront payment, and never cash, gift cards, wire or crypto (FTC, DOJ and CFPB, 2024).
- Taking payment and not starting work within 45 days can be residential contractor fraud (R.S. 14:202.1).
- A contract signed at home may carry a 3-day right to cancel (R.S. 9:3538 and the FTC Cooling-Off Rule), with exceptions for emergency work you asked for.
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). Smaller jobs, like a patch of bathroom mold under about 10 square feet, are often something an owner can handle, per EPA. Attic jobs run $1,500 to $9,000 in Fixr's national estimate (Aug 2025), not a quote. More in the cost guide.
Slidell mold questions
Is mold in Slidell mostly from flooding?
Flooding is a big source, especially in surge-prone areas near the lake, but not the only one. Slidell's 1970s homes also get mold from roof leaks, AC condensation and aging plumbing. A hard freeze, like the January 2025 storm, can split pipes, and a pipe that leaks inside a wall can go unnoticed. Finding the water source is the first job.
How do I spot a storm contractor scam in Slidell?
Be wary of anyone who knocks on your door after a storm. Verify the LSLBC license, get a written contract, and don't make a large upfront payment. Never pay in cash, gift cards, wire or crypto. In Louisiana, taking payment and not starting work within 45 days can be residential contractor fraud (R.S. 14:202.1).
Should I get a mold test before buying a house in Slidell?
It can make sense for a house with a flood history or a musty smell. An independent inspection with moisture readings, and samples if needed, can find hidden growth. Hire an inspector who has no tie to a remediation company; in Louisiana a remediation contractor may not also assess the same property.
