Mold Removal in Slidell, Ten Feet Up and 2,577 Repeat Losses
Send the street and what you are looking at, and we will tell you whether this is an assessment, a removal, a drying job or nothing worth paying for. Slidell sits 10.30 feet above sea level on North Shore terrace soils rather than pumped delta clay, and it still carries 2,577 repeat-loss properties, more than Metairie with five times the houses, so nobody here should be told that being out of the bowl settles it.

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.

City of Slidell, or a Slidell address outside it?
The permit desk, the flood rating and the map date are different in each. Tell us the street and we will work out which one you are in.
A Slidell mailing address is not always the city of Slidell
Read the address before anything else. The city of Slidell issues its own permits and holds Community Rating System Class 6 on a first map dated December 16, 1980, while an address with a Slidell mailing address outside the city line falls to St. Tammany Parish, which holds Class 7 on a map that has not been revised since April 21, 1999. Two houses whose envelopes both say Slidell can sit under different offices, different discounts and different flood determinations, so that is the first thing we check. The ground is North Shore ground: Myatt terrace soil, poorly drained but with very slow runoff and formed on level upland flats, not pumped delta clay. Being ten feet up and outside the bowl has not kept the water away. Properties reporting a Slidell address account for 2,577 repeat-loss properties, the second highest count in this service area and more than Metairie, which has five times the housing. On soils like these the water usually arrives at the surface and stays because the ground will not take it away, which makes grading, gutters and where the yard sheds water as much a part of the diagnosis as anything inside the wall.
