How Much Does Repiping a House Cost? Complete Breakdown

Have you noticed rusty water, leaky pipes, or low water pressure? Maybe your home’s pipes are starting to show their age. Repiping isn’t a project anyone looks forward to—and the costs can feel overwhelming if you don’t know what to expect.

At SDC Plumbing, we handle emergency plumbing and repiping for both homes and businesses, every single day. We know you need clear answers, not surprises.

What is Repiping? 🛠️

Repiping means replacing all—or most—of a building’s water supply pipes. Think of it like swapping out an old, rusty skeleton for a brand-new backbone that keeps water flowing cleanly and safely.

It’s usually necessary if your plumbing is:

• Over 40 years old (especially with galvanized steel or polybutylene)
• Prone to leaks or water discoloration
• Causing low water pressure throughout the property
• Failing safety codes or creating emergency plumbing issues

Repiping can cover cold and hot water lines, and sometimes even gas lines, depending on your building’s needs. For commercial properties, it may include larger diameter pipes for higher volumes.

Factors Affecting Repiping Costs 💡

No two repiping jobs are exactly the same. Here’s what really drives the price up or down:

Pipe Material

• PEX (cross-linked polyethylene): Flexible, affordable, and quick to install.
• Copper: Durable and long-lasting, but pricier. Great for resale value.
• CPVC: Cost-effective, resists corrosion, but can be brittle over time.

House Size & Plumbing Complexity

A small cottage with one bathroom? Much cheaper than a three-story home with multiple kitchens and baths. For commercial clients, costs multiply with the number of fixtures and the complexity of your plumbing layout.

Number of Bathrooms & Fixtures

More toilets, sinks, and showers mean more pipe to lay. Simple math.

Accessibility

Easy access—like exposed basement ceilings—keeps labor down. Pipes buried in thick walls, tight crawlspaces, or under concrete? Expect higher costs.

Regional Labor Rates & Permits

Where you live matters. Urban areas or regions with strict codes (like California or New York) have higher labor costs and permit fees. SDC Plumbing operates nationwide and always factors in your local requirements.

Other Factors

• Home age and construction type
• Need for drywall or flooring repairs after the job
• Emergency plumbing timing (after-hours or weekends)

Average Cost Range

So, what should you budget? Here’s the ballpark—always subject to your location and needs:

Small Homes (1-2 bathrooms)

• Range: $4,000–$8,000

Medium Homes (2-3 bathrooms)

• Range: $8,000–$15,000

Large Homes (4+ bathrooms/multi-story)

• Range: $15,000–$30,000+

Commercial Repiping

• Pricing varies widely based on size, accessibility, type of business, and code requirements. Simple office suites may start around $20,000, while restaurants, apartment buildings, or medical facilities could be much higher.

Tip: These figures cover labor, materials, permits, and basic wall repair. Specialty fixtures, designer finishes, or extensive restoration work will add to your budget.

How to Get an Accurate Estimate

Here’s how to avoid surprises and get real numbers for your project:

1. Request a Site Inspection. Phone quotes can only go so far. SDC Plumbing always recommends a walk-through to see what’s really behind your walls.
2. Ask About Materials. Understand the pros and cons—and cost differences—between PEX, copper, and CPVC for your property.
3. Get a Written Proposal. It should break down materials, labor, permits, and any restoration work.
4. Ask About Timeline. Large repipes can take a week or more; smaller jobs may finish in 1–3 days.
5. Review Local Code Requirements. Some municipalities require specific pipe materials or extra safety checks. SDC Plumbing always follows the latest plumbing code and safety guidelines from authorities such as the International Association of Plumbing and Mechanical Officials (IAPMO).

Frequently Asked Questions

How long does repiping take?

Most homes are finished within one week. Larger or commercial buildings may take longer, especially if complex repairs or after-hours access is needed.

Do I need to move out?

Usually not. SDC Plumbing works in sections, so you’ll have partial water service throughout. For extensive jobs, temporary relocation may make life easier.

Will my walls be ruined?

We aim for minimal disruption, but some drywall cuts are needed. We patch holes, but you may want to budget for full repainting.

Is there a “best” pipe material?

PEX is popular for its affordability and speed, but copper lasts longer and adds value. Your plumber can help weigh the pros and cons for your property.

Local and Seasonal Considerations 🌦️

• Cold Climates: Frozen pipes are more common; insulation is a must.
• Older Neighborhoods: May require careful work to meet local codes or deal with historic materials.
• High Water Table Areas: Sump pump and backflow prevention may be critical.

Budget With Confidence

Repiping is a big step, but it’s an investment in safety, reliability, and property value. Don’t let sticker shock keep you guessing. At SDC Plumbing, we lay out every cost upfront, tailored to your needs—whether you’re a homeowner facing emergency plumbing or a business manager planning upgrades.
