Cost of Replumbing a 3-Bed House: What to Expect in 2025

If you’ve noticed low water pressure, discolored water, or recurring leaks in your home, it might be time to consider a full replumb. For many U.S. homeowners, the cost of replumbing a 3-bed house is a major concern—and understandably so. Replumbing isn’t just a repair; it’s a long-term investment in your home’s safety, efficiency, and value. In this guide, we’ll break down exactly what to expect in 2025, from average costs and material choices to hidden fees and money-saving strategies—all based on real contractor data and industry benchmarks.

How Much Does It Cost to Replumb a 3-Bedroom House?

The average cost of replumbing a 3-bed house in the U.S. in 2025 ranges from $4,500 to $15,000, with most homeowners paying around $8,000–$10,000 for a complete repipe. This wide range depends heavily on three factors:

• Type of piping material (PEX, copper, or PVC)
• Home layout and accessibility
• Labor rates in your region

According to HomeAdvisor’s 2024 Cost Guide and verified contractor data from Angi and Fixr, a typical 1,500–2,200 sq ft, three-bedroom home requires 250–400 linear feet of pipe. Labor alone can cost $45–$75 per hour, often totaling 40–80 hours of work.

💡 Pro Tip: Homes built before 1970 with galvanized steel or polybutylene pipes are high-priority candidates for replumbing due to corrosion and leak risks.

What Factors Influence the Total Cost?

1. Pipe Material Choice

The biggest cost driver is your choice of piping material. Here’s a quick comparison:

Most contractors now recommend PEX for whole-house repiping—it’s 30–50% cheaper than copper and just as reliable for residential use. The U.S. Department of Energy even notes PEX’s energy efficiency due to lower heat loss in hot water lines.

2. Home Age and Layout

Older homes often require wall, floor, or ceiling demolition to access pipes—adding $1,000–$3,000 in drywall repair and painting. A ranch-style 3-bed home with accessible crawl spaces will cost far less than a multi-story house with finished basements.

3. Permits and Inspections

Most cities require plumbing permits for full repipes, costing $100–$500. Skipping this risks failed inspections and lower home appraisal value. Always confirm local codes—some areas (like California) have PEX restrictions you should know before buying materials.

Step-by-Step: What Happens During a Full Replumb?

A professional replumbing job follows a structured process:

1. Inspection & Quote (1–2 days):
   Plumbers use camera scopes to assess pipe condition. They’ll provide a line-item quote showing material, labor, and cleanup costs.
2. Permit Application (2–5 days):
   Your contractor typically handles this. Keep a copy for your records.
3. Shut Off Water & Demolition (1 day):
   Water is turned off. Small access holes (4”–6”) are cut in walls near fixtures. No full wall removal needed in 80% of PEX jobs.
4. Install New Pipes (2–4 days):
   PEX lines are run from the main shutoff to each fixture. A home run (manifold) system is common—it improves water pressure and allows zone control.
5. Pressure Testing (1/2 day):
   Pipes are pressurized to 80–100 PSI for 2+ hours to detect leaks before walls are closed.
6. Patch, Paint & Final Inspection (1–2 days):
   Drywall patches are sanded, primed, and painted. City inspector verifies code compliance.

✅ Real-World Example: In Austin, TX, a 1,800 sq ft 3-bed home repiped with PEX cost $7,200 total—including permits, labor, and drywall repair. The job took 5 days.

How to Save Money Without Cutting Corners

• Bundle with other renovations: If you’re remodeling your kitchen or bathroom, replumb at the same time to avoid double drywall work.
• Choose PEX over copper: Saves $3,000–$6,000 on average.
• Get 3+ quotes: Prices vary widely. A 2024 study by Angi found a 37% average difference between lowest and highest bids.
• Ask about off-season discounts: Winter (Dec–Feb) often brings 10–15% lower rates due to lower demand.

Avoid DIY replumbing. According to the International Code Council, improper installation causes 22% of post-repipe leaks. Even experienced handymen lack certification for pressure testing and code compliance.

Hidden Costs to Watch For

• Asbestos or lead paint abatement (in pre-1980 homes): +$500–$2,000
• Upgrading the main water line: +$1,000–$3,000
• Emergency rerouting (if unexpected rot or pests are found): +$300–$800

Always request a contingency clause in your contract (typically 10% of total cost) to cover unforeseen issues.

FAQ Section

Q1: How long does it take to replumb a 3-bedroom house?

A: Most full repipes take 3 to 7 days, depending on material, access, and crew size. PEX installations are faster than copper due to fewer fittings and no soldering.

Q2: Is replumbing covered by homeowners insurance?

A: Rarely. Insurance typically covers sudden pipe bursts—not aging or corrosion. However, if a leak causes water damage, the repair to stop the leak might be covered, but not the full repipe.

Q3: Can I live in the house during replumbing?

A: Yes, but with limitations. You’ll have no running water for 1–3 days. Plan to use a neighbor’s bathroom or stay elsewhere if you have infants or medical needs.

Q4: Does replumbing increase home value?

A: Yes—by 2% to 5%. According to Zillow, updated plumbing is a top-5 feature buyers notice. It also speeds up sales; 68% of agents say modern plumbing reduces time on market.

Q5: What’s the lifespan of new plumbing?

A: PEX lasts 40–50 years, copper 50–70 years, and PVC 25–40 years. Proper water pressure (under 80 PSI) and pH balance extend pipe life significantly.

Q6: How do I know if I need a full replumb vs. spot repair?

A: Consider a full replumb if:

• Your home has polybutylene pipes (gray, stamped “PB2110”)
• You’ve had 3+ major leaks in 12 months
• Water tests show high metal content (from corroded pipes)
  For isolated issues (one leaky pipe under a sink), a spot repair suffices.

Conclusion

Understanding the cost of replumbing a 3-bed house empowers you to make smart, stress-free decisions. While the upfront price may seem steep, it prevents costly water damage, improves water quality, and boosts your home’s market appeal. With PEX as the modern standard and smart planning, most U.S. homeowners can complete this project for under $10,000—adding decades of peace of mind.
