Whole House Repipe Cost: Top 8 Options & Pricing

If you're dealing with old pipes, low water pressure, or a slab leak, you're probably wondering what a whole house repipe actually costs. In Orange County, pricing varies depending on materials, home size, and who does the work. Below are the top 8 repipe options, starting with our top pick.

1. Repipe OC (Our Top Pick) , Orange County's Trusted Repipe Specialist

 Repipe OC is a full-service repiping company that handles both residential and commercial whole-house repipes in Orange County. They offer a 25-year transferable warranty, free on-site estimates, and 24/7 emergency support. This is the only local contractor we found that explicitly serves both home and commercial properties while providing full price transparency.

We like Repipe OC because they cover what most quotes leave out: drywall repair, permits, and water main replacement are all included. Their team uses PEX pipe, the industry standard for durability and flexibility. And with no hard credit check financing available, a repipe becomes accessible even on a tight budget.

Best for: Homeowners and property managers who want a single provider with a rock-solid warranty and no surprise costs.

Key Takeaway:Repipe OC's 25-year transferable warranty and free estimates make them the safest bet for a whole-house repipe in Orange County.

One caveat: they operate primarily in Orange County, so if you're outside that area, you'll need to look at local options. But for OC residents, this is the gold standard. Check their cost guide for a detailed breakdown .

2. Repiping with PEX Material – Modern, Flexible, Cost-Effective

PEX (cross-linked polyethylene) is the most common repipe material today. It's flexible, resists corrosion. The highest grade of PEX uses an expansion system that creates a strong, leak-resistant joint.

Best for: Homeowners on a budget or those with homes on slab foundations, since PEX can be routed through attics and walls without digging. It's also a top choice for DIYers.

Pro Tip:When comparing PEX quotes, ask for the highest grade of PEX specifically. Confirm the warranty covers both parts and labor , some contractors only cover materials.

A limitation: PEX can be damaged by UV light, so it must be kept out of direct sunlight. It's also not ideal for outdoor exposed runs. But inside your walls, it's proven to last 40, 50 years. Learn more about the repipe process and benefits . According to Wikipedia , PEX has been used in Europe since the 1960s and is now the dominant material in U.S. residential plumbing.

3. Metal Repiping , Traditional Durable Option

Metal repiping costs vary, typically exceeding the cost of PEX. But metal repiping lasts a long time and is naturally antimicrobial. It's also the go-to choice where local codes require metal pipe or if your water is acidic enough to degrade plastic.

Best for: Homeowners who plan to stay in the house long-term and want traditional materials. Also ideal for areas with high UV exposure or where PEX isn't code-compliant.

The downside is labor. This option requires soldering, which takes longer and costs more than PEX expansion joints. On a slab home, those labor hours multiply fast. Some contractors use a hybrid approach: PEX inside walls and metal at the main entry. That's worth asking about. Explore our PEX parts and warranty details .

4. Older Home Repiping , Essential for Older Homes

Older homes often have pipes that rust from the inside out, causing low water pressure, brown water, and frequent leaks. Replacement costs are available on request, but given the age of the pipes, a full repipe is almost always recommended over spot repairs.

Best for: Owners of pre-1960 homes still running original steel lines. If you see rust or experience frequent leaks, it's time.

One honest caveat: repiping a home with older pipes often means dealing with rust debris that can clog new fixtures. A professional repipe includes flushing the system after installation. The 2026 cost guide notes that replacing old pipes is urgent , not optional.

5. DIY Repiping Options , A Cost-Saving Alternative

A DIY repipe can cut labor costs significantly. For a typical home, materials and tools add to the initial investment, but may be worthwhile compared to professional installation. Online tutorials can guide you, but it's a serious weekend project involving drywall cutting, drilling joists, and pressure testing.

Best for: Handy homeowners with experience in light construction and plumbing. If you've never soldered pipes or used an expansion tool, this is risky.

The biggest risk is leaks. One faulty connection can cause thousands in water damage. Plus, most DIY jobs won't have a warranty. If you're not confident, hire a pro.

6. Partial Repiping , Target Specific Areas

If only one section of your home has problem pipes, a targeted repipe can be a cost-effective alternative to a full replacement. Costs vary depending on the scope of work and number of fixtures involved. Common partial jobs include replacing the main water line to the kitchen and bathrooms, or rerouting pipes in a single bathroom during a remodel.

Best for: Homes with isolated pipe failures, or when you're already renovating a specific room and want to upgrade the plumbing there.

But beware: partial repipes can mask bigger problems. If one section of piping has pinhole leaks, the rest is likely aging too. Patchwork fixes often lead to more repairs within a few years. This comparison article explains when a partial repipe makes sense versus a full repipe.

7. Commercial Repiping , Higher Standards, Higher Costs

Commercial repiping costs $6,000 to $25,000 or more, depending on building size, number of floors, and code requirements. Materials often include standard piping materials for drains, and labor rates are higher. Commercial buildings also need proper permits and inspections, which adds time and cost.

Best for: Property managers, landlords, and business owners with multi-unit buildings or commercial spaces needing pipe replacement.

Unique to commercial work: you may need to coordinate with tenants and complete the job during off-hours. Repipe OC offers 24/7 emergency service specifically for commercial clients. If you run a business, downtime is money, so emergency response is critical.

8. Emergency Repiping: When Time Is Money

If a pipe bursts at 2 AM, you need a team that answers the phone. Emergency repiping services cost a premium — rates vary and are typically quoted on an urgent basis, plus time-and-a-half labor. But the alternative is water damage that can run into the tens of thousands. Most emergency repipe teams can stop the leak and start the repipe within hours.

Best for: Anyone facing a sudden leak, slab leak, or burst pipe. If water is spraying, don't wait for business hours.

The downside: emergency services are expensive, and you're often stuck with whatever contractor shows up. That's why having a trusted provider on speed dial matters. Repipe OC offers 24/7 emergency support for both residential and commercial customers, so you get the same warranty and quality even in a crisis.

How to Choose the Right Repipe Option for Your Home

Here's a quick checklist to help you decide:

• Assess your pipes:If you have galvanized steel or polybutylene, plan a full repipe soon. Copper or PEX? Check for leaks or corrosion.

• Get multiple quotes:Ask three contractors for itemized bids that include permit, drywall repair, and water main replacement if needed.

• Compare materials:PEX is cheaper and faster; copper lasts longer but costs more. Choose based on budget and local codes.

• Check warranties:A transferable warranty adds resale value. Repipe OC's 25-year warranty is among the best.

• Consider timing:If you can wait, schedule during the contractor's slow season (winter) for potential discounts.

• Think about upgrades:While the walls are open, consider adding additional plumbing features to save money later.
