How Much Does It Cost to Replumb a Mobile Home? [2025 Data]

The average cost of replumbing a mobile home is $1,000, though most homeowners spend between $600 and $1,600. You may consider repiping an older mobile home if it has lead pipes, which can make the drinking water unsafe. If your mobile home is relatively new, you may still need to replace the plumbing to achieve better water pressure, quieter nights, and warmer showers.

Cost to Replumb a Mobile Home by Number of Fixtures

The cost to replumb a mobile home depends on the number of fixtures, which cost between $600 and $1,600 each, depending on location and ease of access. Fixtures include toilets, sinks, dishwashers, refrigerators, bathtubs, showers, and washer hookups. Residential properties are often bid by feature, rather than square footage, unless it involves new construction. 

Cost to Replumb a Mobile Home by Type

The cost of materials will be one of your most significant expenses. Some common pipe materials include:

• CPVC: $0.50–$1 per linear foot

• PVC: $.95–$1.25 per square foot

• PEX: $.50–$2.50 per linear foot

Many experts recommend PEX when replacing your mobile home’s pipes, as it is better able to withstand freezing temperatures.

Additional Cost Factors When Replumbing a Mobile Home

Several additional factors influence the cost of replumbing a mobile home, including the specific items that need to be replaced or repaired, as well as the size of your mobile home. Here’s what to expect. 

Repairing a Drain Line

If your plumbing job requires repairing your drain line, expect to pay anywhere from $225 to $1,170, with an average cost of around $700. Plumbing repair costs depend on the severity of the repair and the type of material used.

Repairing Floors

The average cost of repairing your mobile home flooring will be anywhere between $7 and $30 per square foot. Plumbing in mobile homes is often run through the flooring, so you may need to replace or repair it when running new pipes. Your final cost will depend on the size of the repair and your type of flooring.

Replacing Lead Pipes

If you live in an older mobile home, consider repiping your entire home if your pipes are made of lead, which typically starts at around $2,500. Lead in drinking water can lead to kidney and brain issues, among other health problems, according to the Environmental Protection Agency (EPA). 

If your home contains galvanized steel pipes or polybutylene, you should also consider replacing the entire plumbing system. Galvanized steel corrodes over time and can reduce water pressure.

Accessibility of Your Pipes

In addition to the actual plumbing work, the accessibility of the pipes can also affect your final cost. For example, you might pay higher rates if pros need to cut through insulation or debris. 

Urgency

If you need immediate repiping in your mobile home and can’t wait until a plumber can fit you into their schedule, be prepared to pay emergency plumbing rates. Emergency plumbers may charge anywhere from 1.5 to 3 times the regular rate for the same level of work during evenings, weekends, and holidays.

Mobile Home Plumber Costs

On average, local plumbers charge between $45 and $150 per hour to replumb a mobile home. The labor component is often the largest part of the total cost, accounting for 60% to 75% of the final bill. That said, having a professional take care of things can save you from costly repairs down the line, as pros are specialized in this type of work.

DIY vs. Hiring a Pro to Replumb a Mobile Home

Unless you’re a licensed plumber, handling the pipework in your own home is unwise. If you make even a small mistake, you could face expensive problems in the future. Pipes that aren’t appropriately installed could leak, resulting in water damage and mold. You’ll also need to navigate the proper angle of the pipes to maximize water flow, and choosing suitable pipes, valves, and connections can be a confusing task.

If you opt to handle new plumbing yourself, obtain a permit from your local city or municipality, which often ranges between $50 and $500. This home improvement project requires proper documentation and inspections. That said, we highly recommend hiring a plumber near you instead. 

Reasons to Replumb Your Mobile Home

Here's a look at reasons why you might need to replumb your mobile home:

• Older, corroded mobile home piping can impact drinking water quality. That’s because some older pipes can cause iron, lead, cadmium, and other toxic heavy metals to leach into your water. Corroded pipes will also begin to flake, rust, or develop holes.

• Worn pipes could eventually begin to leak, potentially leading to water damage or mold.

• Replacing your pipes can help balance your water pressure.

• Rattling piping is a sign of loose or deteriorating pipes, which could benefit from replacement.

• Many pipes that were installed before the 1990s contain pollutants and harmful materials that can leak into your home's water supply. Additionally, any type of piping that is more than 50 years old is due for an upgrade.

Questions to Ask a Mobile Home Plumber

When having any plumbing work done, we always recommend getting quotes from at least three qualified contractors to compare prices and timelines. You can also ask the following questions to narrow down your choice: 

• Is your company licensed and insured? Will the actual plumber who comes out to repipe my mobile home also be licensed and insured? How can I check that the plumber is licensed?

• How do you charge for plumbing work: a flat rate or by the hour? What’s the total estimate for this job?

• What is your company’s experience with replumbing mobile homes? Have you worked on other mobile homes in my neighborhood?

• Is your work backed by any type of guarantee? If so, what are the details?

• What permits are required to repipe a mobile home? Does your company handle obtaining the permit, and if so, will that be reflected in your quote?

• How long do you expect this project to take, and will my family be without water during the project's duration?

• How soon can you start the project?

• What do I need to do to prepare my mobile home for this work? Do I need to clear anything out of the way?

• Do you have any recent client testimonials available? 

• Are there any specific challenges you might encounter with mobile home plumbing vs. traditional home plumbing? What hiccups often arise during this kind of work, and how would those impact the final cost?
