Most homes tell stories. Some whisper. Some groan. Pipes, hidden behind walls and under floors, often do the latter—especially as they age. If you’ve been noticing strange water pressure issues or small leaks cropping up, your home might be trying to get your attention.

At Alexanders Plumbing, we know how stressful plumbing emergencies can be. Repiping is a big step, but understanding the signs and process can help you act before a drip turns into a deluge. Let’s break it down together.

Warning Signs You Need Repiping 🛑

Pipes don’t last forever. Like old shoes, they wear down—sometimes quietly, often with a mess. Here’s how to spot trouble before it becomes a disaster:

  • Low Water Pressure: If your showers feel more like a trickle and your washing machine takes forever to fill, your pipes might be clogged with rust or mineral buildup.
  • Rusty or Discolored Water: Brown or yellow water, especially when you first turn on the tap, is a red flag for corroded pipes.
  • Frequent Leaks: One leak can be a fluke. Two or more? Your pipes could be thinning or splitting behind the scenes.
  • Visible Corrosion: If you can see green, white, or rusty residue on exposed pipes, the rest may be in worse condition.
  • Strange Noises: Banging, rattling, or whistling sounds when you use water often signal pipes that are loose, blocked, or on their last legs.
  • Old Pipe Materials: Homes built before 1970 often used galvanized steel or even lead pipes, both of which are now considered risky and outdated.

Don’t ignore these signs. Repiping could save you from a much bigger emergency plumbing situation down the line.

Repiping Materials (PEX, Copper, and More)

Choosing the right pipe material is like picking the right tires for your car—it affects performance, safety, and longevity.

Common Repiping Options

  • Copper: The classic. Durable, reliable, and lasts for decades. Copper resists bacteria and handles high heat, but it’s pricier and vulnerable to acidic water.
  • PEX (Cross-linked Polyethylene): Flexible and easy to install, PEX bends around corners and through tight spaces with fewer joints. It’s resistant to corrosion and freezing but can’t be used outdoors where UV rays hit.
  • CPVC (Chlorinated Polyvinyl Chloride): Handles both hot and cold water, resists scale and corrosion, but can get brittle with age.
  • PVC (Polyvinyl Chloride): Often used for drain lines, not for hot water supply. Lightweight and affordable.

Factors to Consider

  • Local Codes: Always check your local plumbing codes. Some areas restrict certain materials (for example, PEX may not be allowed everywhere). The Uniform Plumbing Code (UPC) and International Residential Code (IRC) are good references.
  • Water Quality: If your water is acidic or “hard,” it can eat away at copper and clog pipes with mineral deposits. Water softeners or filtration systems may be recommended.
  • Insurance Implications: Upgrading from old, risky pipes (like lead or polybutylene) can sometimes lower your homeowner’s insurance premiums or improve coverage.

The Repiping Process

Repiping isn’t a quick fix—it’s a full home upgrade. Here’s what to expect:

1. Assessment

A licensed plumber inspects your pipes, checking for weak spots, leaks, and outdated materials. Tools like pipe cameras and leak detection equipment help pinpoint issues without tearing up your home.

2. Planning and Permitting

Your plumber maps out the new system, minimizing disruption. Local permits are pulled (as required by law), ensuring everything is up to code and safe for your family.

3. Installation

  • Old pipes are shut off and drained.
  • Small holes are made in walls and ceilings to access the plumbing runs.
  • New pipes (often PEX or copper) are threaded through your home, replacing the old lines.
  • Connections to sinks, toilets, showers, and appliances are carefully tested.

4. Inspection

City or county inspectors may check the work. This protects you—making sure your home is safe, leak-free, and built to last.

5. Restoration

Walls, ceilings, and floors are repaired. Your home is put back together, often looking better than before.

Costs and Financing 💸

Repiping isn’t cheap, but it’s an investment in your home’s safety and value. Here’s what affects the price tag:

  • Home Size: More bathrooms and fixtures mean more pipe.
  • Pipe Material: Copper usually costs more than PEX.
  • Accessibility: Tight crawlspaces or slab foundations can increase labor time.
  • Local Regulations: Permit fees and inspection requirements vary.

For an average single-family home, costs can range from several thousand to over ten thousand dollars, depending on the factors above. Larger homes or those with complex layouts may be higher.

Financing Options

  • Home Equity Loans: Many homeowners use equity to fund major upgrades.
  • Personal Loans: Unsecured loans can offer fast funding.
  • Insurance: While most policies don’t cover repiping, they may cover water damage from a leak. Always check with your provider.

Plan ahead. Compare your options. The right choice can protect your home and finances.

Choosing a Contractor

Repiping is serious business. You want a licensed, insured plumbing professional—someone who follows local codes and pulls the right permits.

What to Look For

  • Licensing and Insurance: Always ask for proof. It protects you if something goes wrong.
  • Experience: Residential repiping is different from new construction. Choose a contractor who knows the ins and outs of older homes.
  • References: Ask for recent jobs in your area.
  • Clear Communication: A good plumber explains the process and sets clear expectations—no surprises.

The National Association of Home Builders (NAHB) and your local building department are good resources when vetting contractors.


Repiping Safety Checklist

Before you start, here’s a quick safety rundown:

  • Check for lead paint or asbestos in older homes before opening walls.
  • Ask your plumber about local code requirements.
  • Make sure all water and gas lines are properly shut off before work begins.
  • Double-check that your contractor is licensed and insured.
  • Notify your home insurance provider about the upcoming work.

Repiping: DIY vs. Call a Pro

Repiping isn’t a weekend project. It’s like trying to rewire your house in the dark. The risks—water damage, code violations, insurance headaches—are too high for most DIYers.

Call Alexanders Plumbing when:

  • Your pipes are leaking in multiple places.
  • Water pressure issues keep coming back.
  • Your home has lead, galvanized, or polybutylene pipes.

If you’re a licensed plumber yourself, you already know the stakes. For everyone else, trust the pros.

What Pros Do On Arrival

When Alexanders Plumbing arrives, here’s what you can expect:

  • Full inspection of your plumbing system, including hidden lines.
  • Leak detection and pressure testing.
  • Clear explanation of your options, from spot repairs to full repiping.
  • Respect for your home—protective covers, careful cutting, and thorough cleanup.

We’ll help you decide if a patch will do or if it’s time for the full upgrade.

Prevention & Maintenance

Repiping is a long-term fix—but don’t forget about maintenance:

  • Schedule regular inspections, especially in older homes.
  • Look out for small leaks and address them fast.
  • Install water filtration or softening if your area has hard or corrosive water.
  • Insulate pipes in cold climates to prevent freezing and bursting.

The American Water Works Association (AWWA) recommends annual plumbing checkups as part of routine home maintenance.

Costs & Time Factors

Repiping usually takes 2–7 days for a typical home, depending on size, complexity, and material choice. Disruption is minimized, but you may be without water for short periods.

Budget not just for pipes and labor, but also for permits, inspections, and minor restoration.

When It’s an Emergency

Sometimes, repiping can’t wait. Burst pipes, major leaks, or water contamination are emergencies. Call an emergency plumbing service right away—don’t wait for water damage to spread.

Keep your plumber’s number handy. Quick action can prevent thousands in damage and costly insurance claims.

FAQs About Repiping

How do I know if my pipes are safe?
If you’re unsure what material your pipes are made of, ask a professional for an inspection. Pipes installed before 1980 are most at risk.

Will my water be shut off during repiping?
Yes, but only for a portion of the process. Most plumbers restore water service at the end of each workday.

Is repiping covered by insurance?
Most homeowners’ policies do not cover the cost of repiping itself, but they may cover water damage caused by a sudden leak. Check your policy or speak with your provider.

How long do new pipes last?
Modern PEX and copper pipes can last 40–70 years or more with proper installation and maintenance.

Local and Seasonal Considerations 🌦️

Climate matters. In cold regions, pipes are more likely to freeze and burst. In areas with hard water, mineral buildup can speed up pipe failure. Always ask your plumber about local water quality and seasonal risks—these factors can shape your repiping plan.

Local building codes may also require certain materials or insulation standards. Your plumber should pull permits and schedule inspections to keep everything up to date.


Your home is your castle. Don’t let aging pipes undermine its comfort or value. Repiping is a big job, but with the right information and a skilled team, you can face it with confidence.
