The Cost to Replace Plumbing in an Old House

Owning an old house is like holding a piece of history. But along with its charm and character comes the reality of outdated systems that may need attention—especially the plumbing. Mr. Rooter Plumbing explains what you need to know and when to call a plumber.

Why Do Old Houses Need New Plumbing?

Old houses were built with different materials and plumbing standards than today’s modern systems. Pipes in these homes might be made from galvanized steel, lead, or cast iron, which can corrode or break down over time.

When these issues arise, the first step is to call a plumber for an inspection. If you’ve experienced frequent leaks or required multiple plumbing repair services, it’s probably time to consider a full replacement.

What Factors Affect the Cost?

The cost of replacing plumbing in an old house varies widely depending on several factors. Here's what can influence the price:

1. Size of the House

Larger homes naturally have more piping to replace, which means higher costs. A small, single-story home may cost less than a sprawling two-story Victorian house.

2. Type of Plumbing Material

Modern plumbing typically uses materials like PEX or copper. PEX is flexible and cheaper to install, while copper is durable but more expensive. A plumbing service can help you decide which material fits your needs and budget.

3. Access to Pipes

If your old house has pipes hidden behind walls, floors, or ceilings, it will take more effort—and money—to access and replace them. Often seen in basements, exposed piping is much easier to replace and cheaper.

4. Extent of the Replacement

Sometimes, only part of the plumbing, like the kitchen and bathroom pipes, needs replacing. If your entire system needs an overhaul, the cost will naturally increase.

5. Labor Costs

Hiring a skilled plumber is essential for quality work, but it’s not cheap. Labor rates can vary based on location and the complexity of the job.

How Much Does It Usually Cost?

While every project is unique, a general estimate for replacing plumbing in an old house ranges from $5,000 to $15,000. Here’s a breakdown of where the money goes:

  • Materials: Depending on the type of pipes, materials can range from $1 to $10 per linear foot. Copper pipes tend to be on the higher end, while PEX pipes are more affordable.
  • Labor: Plumbers often charge between $50 and $200 per hour, depending on their experience and location. For a full house, labor costs can make up a significant portion of the budget.
  • Permits and Inspections: Most cities require permits for plumbing work, which can cost a few hundred dollars.

Consulting a reliable plumbing service will give you a more accurate estimate based on your specific home.

Is It Worth the Investment?

New plumbing can:

  • Prevent Water Damage: Leaky or burst pipes can cause extensive (and expensive) damage to walls, floors, and personal belongings.
  • Improve Water Quality: Replacing old pipes, especially lead ones, ensures cleaner and safer water for your family.
  • Boost Home Value: If you ever sell your house, having a modern plumbing system can attract buyers and increase its value.

In many cases, the cost of replacing old plumbing pays off in the long run by avoiding constant repairs and emergency calls to plumbing repair services.

Can You Save Money?

Here are a few tips:

  1. Get Multiple Quotes: Get estimates from at least three plumbers. Compare their prices and recommendations.
  2. Plan During Renovations: If you’re already remodeling parts of your house, combine it with plumbing replacement.
  3. Choose Cost-Effective Materials: While copper is durable, PEX piping is more affordable and quicker to install.
  4. Tackle Partial Replacements: If a full replacement isn’t in the budget, replace the worst piping sections first and plan for the rest later.

How Long Does It Take?

Replacing plumbing in an old house isn’t a quick job. Depending on the size of the house and the scope of work, it can take anywhere from a few days to several weeks. A professional plumbing service will often provide a timeline before starting the project.
