Quick answer: A professional whole-house repipe follows six steps: (1) inspection & estimate, (2) prep and protecting your home, (3) installing the new water lines, (4) connecting fixtures and testing, (5) permit inspection, and (6) drywall patching and cleanup. The whole process usually takes 1-3 days, and most homeowners stay home throughout.

Worried a whole-house repipe means weeks of chaos and torn-up walls? It doesn’t. A professional repipe is a well-rehearsed process that a skilled crew completes in just a few days with minimal disruption. Here’s exactly what to expect, step by step.

Step 1: Inspection & Free Estimate

A specialist inspects your existing pipes, water pressure, and home layout, then recommends the right material (PEX or copper) and provides a firm, written quote. This is also when you’ll discuss timeline and financing.

Step 2: Prep & Protection

On install day, the crew covers floors and furniture with protective sheeting and identifies the most efficient, least-invasive points to access your pipes. Good prep is what keeps your home clean and the job fast.

Step 3: Installing the New Lines

The team runs brand-new water supply lines throughout the home, making small, strategic wall openings only where needed. This is the core of the job—replacing every worn-out line with fresh PEX or copper.

Step 4: Connecting Fixtures & Testing

New lines are connected to every fixture—sinks, showers, toilets, water heater, and appliances—then the system is pressure-tested to confirm there are zero leaks and full, even water pressure.

Step 5: Permit Inspection

Because repiping must meet code, a permit and city inspection are required. Your licensed contractor handles the paperwork and coordinates the inspection so the work is fully approved and documented.

Step 6: Drywall Patching & Cleanup

Finally, the access openings are patched and textured, and the crew cleans up completely. With a quality repiper, you’re left with new, reliable plumbing and a home that looks the way it did before—minus the failing pipes.

How Long & How Disruptive?

Plan for 1-3 days. Water is only off for part of each day and restored every evening, so most families stay home throughout. Not sure it’s time yet? Review the warning signs of pipe failure or our cost guide.

Frequently Asked Questions

How long does a whole-house repipe take?

Most whole-house repipes are completed in 1 to 3 days, depending on home size, number of bathrooms, and pipe accessibility. Water service is typically restored by the end of each work day.

Do I have to move out during a repipe?

Usually not. Most homeowners stay in their homes during a repipe. Water is only shut off for part of each day, and a good crew protects your living spaces and restores service each evening.

Will a repipe damage my walls?

A repipe requires small, strategic openings in walls to access pipes, but professional crews keep these minimal and patch and texture them as part of the job. Many companies, including ours, include drywall patching so your home is left clean.

Do I need a permit to repipe my home?

Yes. Repiping requires a permit and inspection in San Jose to ensure the work meets code. A licensed repipe contractor handles the permitting and coordinates the inspection for you.
