You’ve decided your pipes are done. Now the real questions kick in: How long will your home be a construction zone? How much will it cost? And can you still take a shower on Tuesday?
Take a breath. A whole house repipe sounds scarier than it is. Done right, it’s a systematic upgrade, not a demolition, and most of them wrap in just a few days.
Here’s what we’ll walk through:
- The step-by-step repiping process, from inspection to final walkthrough
- A realistic timeline you can actually plan around
- What disruption feels like day to day
- The full cost breakdown and what drives the number
- How to choose the right licensed plumber
We repipe Orange County homes and nothing else at OC Repipes, so this is the honest, insider version. No fluff, just what really happens.
What a Whole House Repipe Means
A whole house repipe replaces all the old hot and cold water supply lines in your home with new piping. Every run, from the water heater to your farthest faucet, gets swapped.
It’s the fix for a whole plumbing system that’s failing, not a single pipe repair. Homeowners reach for it when aging pipes bring frequent leaks, rusty or discolored water, or water pressure drops across the house.
The usual suspects behind a repipe:
- Galvanized steel pipes that corrode from the inside out
- Old copper piping developing pinhole leaks
- Lead pipes posing serious health risks
- Deteriorating pipes with heavy mineral buildup choking water flow
Replacing that existing plumbing with modern materials restores reliable flow and clean water for decades. Most jobs today use PEX piping or copper, which we’ll compare on cost shortly.
The Repiping Process, Step by Step

Modern repiping follows a clear system. A good crew moves through your home methodically, which keeps the timeline predictable and the mess contained.
Here’s how a typical repiping project unfolds:
- In-home inspection: A licensed plumber evaluates your existing pipes, water pressure, and problem areas to set the scope
- Material and layout plan: You pick your pipe material, and the crew maps the new plumbing lines
- Permits: Your contractor pulls the permits required by local building codes
- Water shutoff and access: The main water supply is shut off and small access holes are cut into drywall to reach old lines
- Pipe installation: New water supply lines go in, often run alongside disconnected old pipes for easier access and less demolition
- Pressure testing: The new piping is pressure tested to confirm leak-free operation
- Final inspection: A city inspector signs off that the work meets code
- Drywall repair and cleanup: Walls get patched, surfaces restored, and the site cleaned
Ask whether your crew leaves the old pipes in place or rips them out. Leaving disconnected pipes in the walls means far less demolition, which saves you both time and wall repair costs.
How Long Does It Take?
The question everyone asks first. For most homes, a whole house repipe takes 1 to 5 days, with the average landing around 2 to 4 working days.
Here’s a rough day-by-day picture for a standard home:
| Phase | Typical Time | Disruption Level |
|---|---|---|
| Inspection & planning | Before job starts | None |
| Pipe installation | 1 to 3 days | Moderate noise, wall access |
| Fixture hookups & testing | Same or next day | Low |
| Drywall repair & cleanup | 1 additional day | Minimal |
What stretches the timeline? A few things:
- Home size: More square footage means more pipe and more hours
- Fixture count: Extra bathrooms, sinks, and washing machines add connections
- Access: Two-story homes, slab foundations, and tight pipe walls slow things down
- Layout complexity: Older plumbing systems with odd routing take longer
Bigger or more complex homes may run the full five days. Even then, it’s faster than most homeowners fear.
What the Disruption Actually Feels Like

Here’s the reassuring part. You can usually stay home during a repipe.
Water gets shut off only during active working hours, and in most cases it’s restored by the end of each workday. So you sleep in your own bed with a working shower each night.
What to expect while the crew works:
- Noise: Drilling and cutting during the day, quiet by evening
- Access holes: Small, controlled openings in drywall where pipes run
- Foot traffic: Crews moving through work areas, with safe zones kept clear
- Dust: Manageable with proper containment
That last point separates the pros from the amateurs. A quality crew uses dust control to keep your home livable, and full cleanup should be part of the deal, not an afterthought. At OC Repipes, HEPA dust control and complete cleanup come standard, so jobs run up to 98% cleaner than a typical tear-out.
Whole House Repipe Costs
Repiping costs vary significantly depending on your material, home size, and access, but here’s the honest range.
A whole house repipe typically runs $3,000 to $15,000 or more, with most average homes landing in the middle. Your pipe material is the biggest single lever.
| Cost Factor | PEX | Copper |
|---|---|---|
| Typical whole-house range | $4,000 to $10,000 | $8,000 to $15,000+ |
| 1,500 sq ft home average | Around $5,500 | Noticeably higher |
| Relative cost | 30 to 50% cheaper | Premium |
| Install speed | Faster | Slower (soldered joints) |
A few things beyond material that move your total:
- Labor costs: Usually 40 to 60% of the total bill
- Permits and inspections: Add roughly $50 to $800
- Foundation type: Slab homes cost more when rerouting is needed
- Wall repair: Drywall patch and paint can add 10 to 20% to the job
The value angle: A repipe isn’t just spending. New pipes can boost home value by 2 to 5%, improve water flow rates by up to 60%, and eliminate lead-leaching surfaces for safer water. They also cut future repair costs by ending the leak-patch cycle.

How to Choose the Right Contractor

Not all repipe crews are equal, and this is a job you want done once. A little vetting up front saves you real pain later.
What to look for in a repiping contractor:
- Proper licensing and whole-house repiping experience specifically
- Comprehensive insurance covering the work and your property
- On-site evaluations from at least three licensed contractors
- A detailed estimate that includes permits, drywall repair, and cleanup
- Positive testimonials and real customer reviews
- Transparent, flat-rate pricing with no vague line items
Get the full scope in writing before you sign. The most common billing surprise is drywall repair quietly left out of the base quote. Confirm patching, painting, and cleanup are bundled in.
That all-inclusive approach is exactly how we run things. A repipe from OC Repipes rolls inspection, permits, installation, drywall repair, and cleanup into one clear price, backed by a Lifetime Warranty on workmanship. What we quote is what you pay.
Why Homeowners Repipe in the First Place
Nobody repipes a house for fun. It’s a decision forced by an entire plumbing system that’s quietly turning against you, and understanding the why helps you judge whether you’re actually there yet.
Repiping involves replacing every aging supply line in your home’s plumbing system with new piping material. Not a patch, not a spot fix, but a full reset of the plumbing infrastructure behind your walls.
Here’s what usually pushes homeowners over the edge:
- Frequent repairs: When leaky pipes turn into a monthly ritual, you’re funding an endless patch job on a dying system
- Corroded pipes: Old iron pipes and galvanized lines rust from the inside, and outdated materials only get worse with age
- Water quality issues: Corroded pipes shed rust and sediment into your cold water lines, hurting taste and safety
- The burst pipe threat: Poor quality materials fail without warning, and one burst pipe can flood a room in minutes
Think of the math this way. Chasing leak after leak on the same tired lines is like bailing water from a boat with a growing hole. Each repair costs money, and none of them fix the real problem.
Pro tip: Book a professional plumbing inspection before you commit. A licensed plumber checks your exposed pipes, shut off valves, and plumbing fixtures, then gives you honest cost estimates instead of guesswork. Sometimes a targeted fix buys you time. Sometimes it’s genuinely repipe-a-house territory.
The upside makes the case for itself. Swapping all the plumbing for a new plumbing system built on a flexible piping system ends the costly repairs, restores clean water, and future-proofs your home for decades.
And the disruption fear? Overblown. Modern repiping projects favor leaving old pipes in place over messy pipe removal, which means minimal disruption to your daily life. You weigh the labor and material costs once, then stop bleeding money on repairs that never stick.
