Mold Assessment in Covington Where Water Perches Above the Fragipan

A survey that checks whether the winter water sitting in Covington's soil is reaching the house, or whether the damp is the summer air instead.

Mold Assessment quote in Covington

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?

Covington's fragipan, drainageways and housing ages

Covington's Census Bureau interior point stands 22.24 feet above sea level under the USGS national elevation dataset, the highest of the sixteen places in this service area and about twenty-eight feet above Kenner's.

The USDA official series description for Savannah, widely mapped in St. Tammany Parish, is a moderately well drained fine-loamy soil with a fragipan, a dense layer of moderately slow permeability, above which a water table is perched at a depth of 1.5 to 3.0 feet below the surface during the wet seasons from January to March.

The USDA official series description for Guyton, mapped along the flood plains and stream terraces of St. Tammany Parish, describes a poorly drained silt loam, very poorly drained where ponded, with slow permeability and a seasonal high water table from the surface to 1.5 feet deep from December through May, and rare, occasional or frequent flooding.

Covington has 4,640 housing units with a median year built of 1991, the newest in this service area, yet 354 of them, 7.6 percent, were built in 1939 or earlier, the fourth highest pre-war share here. 944 units, 20.3 percent of the whole stock, were built between 2010 and 2019.

Local Context

Why Covington high ground still holds water

Covington sits higher than anywhere else we cover, 22.24 feet above sea level, and its ground still holds water close to the surface for part of the year. Savannah, widely mapped in St. Tammany Parish, has a fragipan, a dense layer that water sits on, with a water table perched 1.5 to 3 feet down from January to March. Along the drainageways, Guyton soils carry a seasonal high water table from the surface to 1.5 feet deep from December through May. A Covington survey therefore asks two questions of a damp wall: is winter ground water reaching the foundation, or is summer air condensing on a cooled interior surface, and it measures both.

Deciding

What to note about a Covington lot before the survey

Note how close the lot is to a drainageway or low ground, and whether the yard holds water between December and May. Tell the surveyor whether the house is one of the 354 built before 1940 or one of the 944 built in the 2010s, because an old raised house and a new slab one fail in different places. If water has come in before, the report should document it; Covington has 330 repeat-loss properties despite its height. Inside the city the flood rating is Class 8; the parish outside it is Class 7.

  1. How near the lot is to a drainageway

    Guyton soils along drainageways hold water near the surface from December through May. Proximity changes the whole diagnosis.

  2. Pre-war or 2010s

    354 Covington homes predate 1940 and 944 went up in the 2010s. The age tells the surveyor where to look first.

  3. Whether it has flooded before

    Covington's height has not kept 330 properties from flooding more than once. A history belongs in the report.

Does the yard hold water between December and May?

Tell us where it stands and how close the lot is to a drainageway. On Covington soils that is half the survey.

Questions

Covington survey questions about ground water

Covington is high ground. Why would we have water under the house?

Because height does not stop water sitting in the soil. Savannah soils here carry a perched water table 1.5 to 3 feet down from January to March above a dense fragipan, and Guyton soils along drainageways can be wet from the surface down to 1.5 feet from December through May. Water standing that close to a foundation is something a survey measures at the slab edge or under the floor.

Is testing for mold part of a Covington survey?

Only where a number would change the decision, which is not often. The EPA says sampling is usually unnecessary where growth is visible, and the CDC does not recommend testing. The Covington survey spends its time on the ground, the foundation line and the walls instead.

Next Step

Send the Covington house and what the ground does

The build year and where water sits after rain. A person reads it and says what the survey would cover.
