pipes and plumbing - home

If you own an older home, chances are the plumbing system is showing its age. Pipes made from materials like galvanized steel, cast iron, or even lead were common decades ago, but they don’t hold up forever. Over time, these older pipes can corrode, clog, or even leak, putting your home at risk for water damage. That’s why many homeowners eventually need to replace the plumbing in their old house. But how much does it actually cost to repipe a home? Let’s break down what you can expect, especially if you live in Brevard County, FL.

Average Cost to Replace Plumbing in an Old House

The cost to replace plumbing in an old house can vary widely depending on the size of your home, the number of bathrooms, and the type of materials used. On average, homeowners can expect to spend anywhere from $4,000 to $15,000 for a whole-house repipe. For smaller homes with just one bathroom, the cost may fall closer to the $4,000 to $6,000 range. Larger homes with multiple bathrooms and complex layouts often land between $7,000 and $12,000, while big homes over 3,000 square feet can climb to $15,000 or more.

The Biggest Factors That Affect Plumbing Replacement Costs

Several factors determine the total price of a repiping project. The first is the size of your home and the number of fixtures. More bathrooms, sinks, and appliances connected to the plumbing system means more pipe to replace, which increases labor and materials. The second factor is pipe material. PEX piping is one of the most affordable and widely used options today. It typically costs between $1.50 and $3.00 per linear foot installed and is known for its flexibility and resistance to scale and corrosion. CPVC piping is another choice and usually runs from $1.50 to $4.00 per linear foot, but it isn’t as flexible as PEX. Copper piping is durable but the most expensive option, often ranging from $3.00 to $8.00 per linear foot installed.

Labor and accessibility also play a huge role in the final cost. Homes with crawl spaces or basements are easier and cheaper to work on since plumbers have better access to the pipes. Older Florida homes built on slab foundations often require cutting into walls and floors to reach plumbing lines, which increases labor costs and adds to the price of drywall and painting repairs once the project is finished. In addition, older homes may hide surprises like outdated wiring, hidden leaks, or structural issues that can add to the overall expense.

Special Considerations for Old Houses

Replacing plumbing in an older home isn’t always straightforward. Many older houses in Melbourne, Palm Bay, and surrounding areas still have galvanized or cast-iron pipes that are well past their lifespan. Some even contain lead piping, which must be replaced immediately for health reasons. Rerouting pipes to modernize the layout is also common, especially if you’re planning to remodel bathrooms or kitchens. Because these challenges are more likely in older houses, costs can run higher than in newer homes. However, the investment is well worth it since modern plumbing materials like PEX can last 50 years or more.

Plumbing Replacement Costs in Brevard County, FL

In Brevard County, local plumbing companies often recommend PEX repiping because it’s affordable, reliable, and suited to Florida’s climate. For a standard two-bathroom home in Melbourne or Palm Bay, repiping with PEX usually costs between $6,000 and $9,000. Choosing copper, while possible, raises the price significantly to $10,000 to $15,000 or more. Because every house is different, the best way to know what your project will cost is to schedule an inspection and get a detailed estimate from a licensed plumber.

How Long Does a Whole-House Repipe Take?

The good news is that most repiping projects don’t take as long as homeowners expect. For an average home, the process can usually be completed in two to five days. If your plumber also handles drywall repair and painting, the entire project may take a little longer. In general, however, a full repipe can be finished in less than a week, leaving you with a brand-new plumbing system that is safer, more reliable, and built to last for decades.

Frequently Asked Questions About Replacing Plumbing

How do I know if my house needs new plumbing?
Signs include rusty or discolored water, frequent leaks, low water pressure, and pipes that are more than 40–50 years old. If your home still has galvanized or cast-iron pipes, it’s time to consider repiping.

Is PEX better than copper for old houses?
PEX is generally the best option for older homes because it is flexible, easier to install, and resistant to corrosion. Copper is long-lasting but costs significantly more.

Will repiping damage my walls?
Some drywall or tile removal is often necessary to reach pipes, especially in slab foundation homes. A good plumber will keep this damage to a minimum and handle repairs after the repipe.

Does homeowners insurance cover repiping?
In most cases, insurance will not cover the cost of whole-house repiping, though it may cover water damage caused by pipe failure. Always check with your insurance provider for details.

How long does new plumbing last?
PEX and CPVC pipes can last 50 years or more, while copper may last even longer. Choosing high-quality materials and professional installation ensures the best lifespan.
