Metairie sits just across the parish line from New Orleans, a large, largely mid-century suburb of slab homes built on reclaimed marshland in Jefferson Parish. It shares the metro area’s low, flat, water-rich geography and most of its drain challenges, with a few distinctions of its own — and the local pros in our network serve it with the same standards as the city proper.
Reclaimed marsh and settling ground
Much of Metairie was developed on drained and filled marshland, and that history shapes its plumbing. The soils continue to settle and compact, bending buried sewer laterals into the bellies and low spots that cause recurring stoppages — the same subsidence story as Gentilly and Lakeview across the line. A Metairie home that backs up repeatedly in the same way is a strong candidate for a camera inspection that checks for a bellied or offset line, because that’s a problem cabling can’t solve.
Slab-on-grade, mid-century construction
Metairie’s housing is predominantly slab-on-grade, built from roughly the 1950s onward, which means a mix of older cast iron and clay in the earliest homes and PVC in the newer ones. Drain lines run within or beneath the slab, so under-slab issues call for precise camera locating, while the more common downstream clogs clear through the lateral normally. The mid-century vintage of much of the neighborhood means a lot of laterals are now reaching the age where material problems — scale, cracks, root entry — start to appear.
A separate drainage and sewer system
Metairie and unincorporated Jefferson Parish are served by Jefferson Parish’s own water and drainage systems, separate from the New Orleans Sewerage & Water Board, with their own pumping and their own permitting for sewer work. The practical upshot for homeowners is the same as in the city: drainage depends on pumps, heavy rain can surcharge the system and back water toward low-connected homes, and any sewer lateral work must be done by a licensed plumber pulling the appropriate parish permits.
Grease, roots, and the suburban line
The everyday clog culprits are universal across the parish line. Kitchen grease on flat-running lines is the leading cause of suburban Metairie backups, just as it is in the city, and jetting is the lasting answer for a chronically greasy line. As the neighborhood’s trees have matured, root intrusion into older laterals has become a steady source of recurring stoppages, handled with the same cut-clear-and-seal approach used everywhere in the metro.
Common Metairie & Jefferson Parish calls
- Bellied laterals from reclaimed-marsh subsidence.
- Kitchen grease clogs on flat suburban lines.
- Root intrusion into aging mid-century laterals.
- Storm-driven backups tied to parish drainage surcharge.
- Under-slab line diagnosis with camera locating.
