Whole-House Repiping in Kenner, LA

When an older home suffers its second or third foundation leak, making isolated spot repairs quickly becomes an expensive, short-term gamble. In Jefferson Parish, many slab homes built throughout the 1960s, 70s, and 80s contain subterranean copper networks that have reached the end of their operational design life. Investing in complete repiping Kenner homeowners rely on replaces your compromised underground plumbing with a dependable overhead piping system, permanently eliminating the fear of future under-slab ruptures.

When Repeat Leaks Mean the System Is Failing

Copper pipe degradation rarely happens at just a single point. If an under-slab pipe in your Kenner home developed a pinhole leak due to acidic soil interaction, localized friction, or internal water erosion, the remainder of that underground pipe network has been exposed to the exact same corrosive forces for the exact same number of decades.

Often, when a plumber patches a single spot leak under the slab, restoring full municipal water pressure simply transfers hydrodynamic stress to the next thinnest section of pipe, sparking another leak weeks or months later. If you have already repaired one slab leak, committing to a complete whole house repipe Kenner project is generally far more cost-effective than repeatedly opening concrete floors and repairing water damage.

Polybutylene Replacement and Galvanized Pipe Upgrades

Beyond aging copper, many Kenner homes constructed between the late 1970s and mid-1990s were fitted with gray polybutylene plastic piping. Polybutylene reacts poorly with municipal water disinfectants, leading to micro-fractures in plastic fittings and sudden catastrophic bursts. Similarly, legacy galvanized iron lines suffer severe internal rust scaling, restricting water volume and releasing rusty flakes into faucets.

Our specialized repiping services include full polybutylene replacement Kenner homeowners can trust, as well as galvanized pipe decommissioning, upgrading the entire domestic water delivery system to current building codes.

PEX Versus Copper: Choosing the Right Modern Material

Homeowners undertaking a repipe can choose between two proven plumbing materials:

Order of Work: Room-by-Room Process

A whole-house repiping project follows an orderly, systematic workflow designed to minimize disruption to your everyday routine:

1. Protection and Preparation: Technicians lay protective drop cloths and plastic sheeting across flooring and furniture along all working pathways.
2. Overhead Trunk Installation: Main hot and cold supply lines are run through the attic or ceiling cavities from the water heater and main service entry.
3. Precision Wall Drops: Small, neat drywall access cuts are made behind fixtures in kitchens, bathrooms, laundry rooms, and hose bibs to drop new supply lines to each valve.
4. Manifold Integration and Shutoff Valves: Brand new, quarter-turn ball valves and braided stainless steel supply lines are connected to every sink, toilet, and appliance.
5. Pressure Testing and Changeover: The entire new overhead system is subjected to a comprehensive air and water pressure test. Once verified leak-free, the municipal connection is switched over, and the old sub-slab lines are permanently drained and abandoned.
6. Drywall Restoration: All drywall cuts are professionally patched, taped, mudded, and textured, leaving your living space clean and orderly.

Jefferson Parish Permits and Code Inspections

Repiping a home represents a substantial capital improvement. We handle the entire permitting process with the Jefferson Parish Department of Inspection and Code Enforcement, coordinating official on-site inspections to ensure full compliance with the Louisiana State Uniform Construction Code.
