What is Whole-House Repiping?

Whole-house repiping, often called a full plumbing replacement or re-piping, is a major home improvement project where all the old water supply lines are removed and new ones are installed. This isn't a spot repair for a single leak; it's a systemic upgrade for your home's entire freshwater distribution system. In New Orleans, this is particularly relevant for homes built before the 1970s, which often contain galvanized steel or even lead pipes that are prone to internal corrosion and failure over decades ^{1 2 3}.

The primary goals of a repipe are to:

• Restore strong, consistent water pressure throughout the home.
• Eliminate the risk of leaks inside walls and under floors.
• Ensure clean, safe drinking water by removing corroded or lead-containing pipes.
• Bring the plumbing up to modern building codes and standards.
• Provide a reliable plumbing foundation that can last for 50 years or more.

The Repiping Process: A Step-by-Step Overview

A professional plumbing replacement is a multi-stage project that requires careful planning and execution. Here's what you can typically expect from start to finish.

1. Inspection and Planning

The process begins with a thorough assessment. A licensed plumber will inspect your current plumbing system to identify the pipe materials (e.g., galvanized, copper, lead), locate the main supply line, and map out the existing layout. They will check for signs of corrosion, leaks, and code violations. This evaluation allows them to design an efficient new system and provide a detailed quote ^{4 5 6}.

2. Obtaining Permits

In New Orleans, repiping a home requires permits from the city to ensure the work complies with local plumbing codes. A reputable plumbing contractor will handle this paperwork, which is essential for both your safety and for future home sales ^{1 7}.

3. Preparing the Home and Creating Access

Before work begins, the crew will move furniture and cover belongings with drop cloths to protect them from dust. Since pipes are hidden inside walls, ceilings, and under floors, strategic access points must be created. Plumbers cut small, precise holes to reach the old plumbing network. The goal is to minimize disruption, but homeowners should expect some drywall and ceiling removal ^{4 8 6}.

4. Removal and Installation

The old pipes are carefully disconnected and removed. Then, the new piping material-such as flexible PEX or rigid copper-is run through the walls and floors, connecting all fixtures (sinks, toilets, showers, appliances) back to the main water line. This stage is the core of the repiping job and requires significant skill to ensure proper sizing and routing ^{5 9 8}.

5. System Testing and Inspection

Once installed, the new system is pressurized with air or water in a "pressure test" to check for any leaks at the connections. This crucial quality-control step ensures the integrity of the installation before the walls are closed up. The work may also be inspected by a city official to verify code compliance ^{4 7}.

6. Patching and Restoration

After the plumbing passes inspection, the access holes in your drywall and ceilings are patched, taped, and sanded. Basic texture matching is usually included, but repainting the patched areas is typically the homeowner's responsibility. The site is then cleaned up, leaving your home fully functional ^{4 6}.

Choosing the Right Piping Material

The material chosen for your new pipes is a major factor in cost, longevity, and installation complexity. Here are the most common options used in New Orleans repiping projects.

PEX (Cross-linked Polyethylene)

PEX has become the most popular choice for whole-house repipes, especially in retrofit situations.

• Pros: It's highly flexible, allowing it to be snaked through walls with fewer access holes and connections, which reduces labor time and cost. It's resistant to scale and corrosion, doesn't pinhole like copper, and performs well in freeze conditions. Installation is faster than with rigid pipes ^{4 10 11}.
• Cons: It cannot be used outdoors (UV light degrades it) and requires special brass or plastic fittings.

Copper

Copper has been the traditional standard for water lines for decades.

• Pros: It is extremely durable, has a long lifespan, and is naturally resistant to bacteria. It can be used indoors and outdoors and is often preferred for its reliability and perceived value ^{10 2 9}.
• Cons: It is significantly more expensive than PEX, both for material and labor. Installation is more labor-intensive, requiring soldering at every joint. It can also be susceptible to pinhole leaks from acidic water over time.

CPVC (Chlorinated Polyvinyl Chloride)

CPVC is another plastic piping option.

• Pros: It is cost-effective, easy to cut and glue, and resistant to corrosion.
• Cons: It becomes brittle over time and can crack if frozen. It is generally less favored for whole-house repipes compared to the flexibility and durability of PEX ^{11 9}.

Project Timeline and Cost Considerations

How Long Does Repiping Take?

For an average-sized New Orleans home, such as a shotgun or camelback, a complete repiping project typically takes 2 to 5 days ^{4 12}. Larger homes, multi-story properties, or those with complex layouts can extend the timeline to 7 to 10 days ⁷. The choice of material also affects duration; a PEX installation is generally faster than copper.

Understanding Repiping Costs in New Orleans

Costs vary widely based on home size, number of bathrooms, material choice, and the complexity of accessing pipes. The figures below are general estimates; always get detailed quotes from local contractors.

• PEX/CPVC Repipe: Generally the most affordable option, with total project costs often ranging from $4,000 to $8,500 for a full repipe of an average home ^{10 3 11}.
• Copper Repipe: A premium option due to material and labor costs, often ranging from $10,000 to $20,000 or more for a full replacement ^{10 3}.
• Overall Range: Partial repipes can start around $1,500, while extensive whole-house repipes, particularly with copper in a large historic home, can exceed $20,000 ^{10 3 12}.

Special Considerations for New Orleans Homes

Repiping in the Crescent City comes with unique challenges and considerations.

• Historic Construction: Many homes have plaster walls, intricate trim, and limited crawlspace access. An experienced plumber will know techniques to minimize damage to these historic features.
• Old Pipe Materials: It's common to find original galvanized steel pipes, which rust shut from the inside, or even lead service lines. Replacing these is a significant health and functional upgrade ^{1 2 3}.
• Local Expertise is Key: Seek out licensed, insured plumbers who have specific experience with New Orleans' housing styles, local codes, and the common issues presented by our climate and aging infrastructure.
