Jefferson Parish

Mold Removal in Gretna, 1,378 Pre-War Houses and a Rental Majority

Send what you are seeing and we will tell you whether it is a leak, a cold surface the air conditioning is making, or nothing worth paying anyone for. Gretna holds the highest pre-war share in Jefferson Parish, 1,378 of its 8,352 homes built in 1939 or earlier, and just over half its occupied homes are rented, so the first question here is often who is responsible rather than what is behind the wall.

Tell us what you can see or smell, roughly where in the house it is, and whether the house is raised or on a slab. Those three things narrow it more than the size of the patch does, because they point at how the water is arriving rather than where it ended up.

Six quick questions, then your details. It takes under a minute, and the answers are what a local assessor would ask first.

Question 1What are you dealing with?
Question 2Is the house raised, or on a slab?

This is the question that splits the job in this metro, and the two answers have almost nothing in common. A raised house has a vented space underneath that pulls in outside air, so the problem is usually the floor system. A slab house has its plumbing cast into the concrete, so the problem is usually a leak you cannot see reaching the bottom of the wall. Answer with whatever you know.

Question 3Where do you think the water is coming from?

Worth knowing before you answer: in this climate a wall can get wet with no leak at all. The mean dew point at the airport is 75.2F in July, which is at or above the temperature air conditioning holds a wall at, so the room's own cooled surfaces can pull water straight out of the air. If none of the leak answers fit, that is genuinely useful information and not a wasted question.

Question 4Is anything still wet?

EPA guidance gives wet material roughly 24 to 48 hours before growth starts, which is why the date matters more than anything else here. One local caution: opening the windows to dry a room out does not work here in summer, because the outside air is carrying more water than the room is.

Question 5What is your position at the property?

It changes who we talk to and what has to be put in writing. Worth knowing if you rent: a landlord's own maintenance staff are exempt from the mold remediation license under Louisiana law, so work handled in house was not done by anyone the state was holding to it.

Question 6How soon do you want someone out?

Where is the property?

Planning

Gretna runs its own permits, and its flood map starts in 1970

Gretna runs its own permitting and its own floodplain administration, separately from unincorporated Jefferson Parish, and holds Community Rating System Class 5 for a 25 percent discount inside the special flood hazard area. Its first flood insurance rate map took effect on August 14, 1970, the earliest date of any community in this service area, and 657 of the city's 753 repeat-loss properties, 87 percent, were built before it. The housing matches that date. 1,378 homes here were finished in 1939 or earlier, the highest pre-war share in the parish, so raised construction over an open or vented space is common and the assembly under the floor is usually the original one. The other thing to settle early is who is asking. Just over half of Gretna's occupied homes are rented, the highest share in this service area, and Louisiana makes it a violation for a mold remediation contractor to fail to give a written report to the person he does the work for. Whether that person is you or your landlord decides who holds the findings afterwards, so tell us which you are when you write and we will tell you what to ask for.

In Gretna that decides who orders the assessment and who ends up holding the written report. It is worth settling before anyone opens a wall.
