Replacing plumbing in a manufactured home typically costs $4,000-$12,000 for a whole-home repipe, with an average near $7,500; small partial replacements may cost $1,000-$4,000. Home size, pipe material, access beneath the floor, water-heater connections, and local labor rates drive the final quote.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Partial pipe replacement | $1,000 | $2,500 | $4,000 | One room or a limited supply-line repair |
| Whole-home repipe | $4,000 | $7,500 | $12,000 | Typical single- or double-wide with accessible runs |
| Extensive repipe and restoration | $10,000 | $15,000 | $20,000+ | May include difficult access, drain work, or floor repairs |
| PEX supply pipe | $0.50 | $1.25 | $2.50 | Pipe material per linear foot, excluding installation |
What a manufactured-home repipe usually costs
A plumber may charge $4,000-$8,000 to replace accessible water-supply lines in a typical single-wide and $6,000-$12,000 for a double-wide. A basic job often uses PEX, reconnects existing fixtures, and leaves drains in place. Larger homes, premium materials, concealed routing, or extensive finish repairs can push a quote above $12,000.
Partial work costs less when the problem is isolated. Replacing a short run to a bathroom or kitchen may run $1,000-$2,500, while a more involved partial repipe with several branches may reach $4,000. Supply piping and drain, waste, and vent piping are distinct scopes; replacing both can increase the total substantially.
For budgeting, use roughly $7,500 for an accessible whole-home supply repipe, then adjust for home size and access. Assumptions: U.S. midrange labor rates, standard PEX, existing fixtures reused, and no major subfloor or structural repairs.
How pipe, labor, and access shape the quote
A written estimate should identify which lines are being replaced, the pipe material, access work, fixture reconnections, and cleanup. Prices below are planning ranges, not fixed national rates; a contractor may group several items into one labor charge.
| Quote component | Low | Average | High | Typical scope |
|---|---|---|---|---|
| PEX supply pipe and fittings | $500 | $1,200 | $2,500 | Materials for a whole-home supply repipe |
| Plumbing labor | $2,000 | $4,500 | $7,500 | Routing, connections, pressure test |
| Access and opening work | $300 | $1,000 | $3,000 | Access panels, belly wrap, or limited wall openings |
| Fixtures and water-heater connections | $200 | $700 | $1,800 | Reconnects or replacement shutoff valves |
| Permits and inspection | $0 | $250 | $800 | Varies by jurisdiction and project scope |
| Disposal and patching | $100 | $500 | $2,000 | Old pipe removal and basic surface restoration |
Not every project includes each charge. For example, a contractor might not open finished walls if lines can be routed through a cabinet or under the home. Conversely, damaged insulation, wet belly material, or inaccessible fittings can add labor and restoration charges.
Separate plumbing work from finish restoration in the estimate so the repipe price is easy to compare.
How home width, pipe length, and access change pricing
Home size is a useful starting point, but the number and layout of fixtures matter too. A 600-900-square-foot single-wide with one bathroom usually needs fewer branches than a 1,200-1,800-square-foot double-wide with two bathrooms, laundry, and multiple kitchen or utility connections.
Pipe material also affects the bid. PEX is commonly used for supply lines because it is flexible and can reduce the number of fittings; material may cost about $0.50-$2.50 per linear foot, before labor. Copper can cost $2-$6 per linear foot for pipe alone and often requires more labor. Local code, water chemistry, and contractor practice influence the selection.
Access can be a major price driver. If the plumber can reach lines through a sound underbelly or existing access panels, costs may stay near the lower end. A damaged belly wrap, tight crawl space, blocked route, or need to open walls can add roughly $500-$3,000 or more. Replacing 100-200 linear feet of pipe is not equivalent to replacing the same length in a home with several hard-to-reach fixture branches.
Ask whether the quote includes the belly wrap and insulation repairs, not just the plumbing line work. A repipe may also reveal water damage that cannot be priced accurately until the access area is opened.
Where labor hours rise on a single-wide or double-wide
A straightforward supply repipe may take a two-person crew 1-2 days, or about 16-32 crew-hours. Work that involves extensive access, multiple bathrooms, old shutoff valves, or patching can take 3-5 days. At a plumbing labor rate of about $75-$150 per hour, billed hours can account for several thousand dollars of a total quote.
Manufactured homes can have narrow chases, low underfloor clearance, and factory-installed components that require careful routing. A double-wide may also have plumbing connections across the marriage line between sections. If those joints are difficult to reach or have prior leaks, a plumber may need additional setup and testing time.
Before approving the job, ask whether the labor estimate is based on a fixed project price or an hourly rate, how many workers are expected, and what conditions trigger extra charges. A fixed bid can still include exclusions, so the scope should spell out fixture reconnections, pressure testing, and cleanup.
Compare the assumed crew-hours and access plan, not only the bottom-line labor charge.
How regional rates shift manufactured-home plumbing prices
Labor and permit costs vary by location. In lower-cost rural markets, a standard repipe may come in about 10%-20% below a national midrange estimate, though travel distance or limited contractor availability can offset that difference. Large metro areas and high-cost coastal markets may run 15%-35% higher, especially where licensed plumber rates and disposal fees are elevated.
Climate affects the work as well. In colder regions, freeze-damaged lines and the need to protect exposed piping can add scope. In hot or humid areas, deteriorated underbelly material or moisture damage may need repair. These conditions are site-specific; they do not automatically make a repipe more expensive.
Request quotes from contractors familiar with manufactured homes in the same county or service area. Confirm licensing requirements, insurance, and whether the estimate covers local inspection fees. If a contractor must travel a long distance, the quote may include a service or mobilization charge.
Use local written bids for the final budget because regional adjustments can change a national range by thousands of dollars.
Three repipe examples show where the money goes
These examples illustrate common scope differences. They assume standard PEX supply lines and existing fixtures; local pricing and hidden damage can change totals.
| Scenario | Work included | Estimated total | Cost context |
|---|---|---|---|
| Small single-wide, 700 sq. ft. | One bathroom and kitchen supply lines, 1-2 days | $4,000-$6,000 | About $5-$9 per sq. ft., with accessible runs |
| Double-wide, 1,400 sq. ft. | Two bathrooms, kitchen, laundry, 2-3 days | $7,000-$11,000 | About $5-$8 per sq. ft., standard PEX routing |
| Older home with damaged underbelly | Supply repipe, access work, belly repair, limited patching | $10,000-$16,000 | Added restoration and difficult access |
Square-foot rates are a comparison tool, not a reliable stand-alone bid method. A smaller home with a long, complicated pipe route can cost more per square foot than a larger home with accessible branches. The quote should list actual fixtures and lines covered.
Check the fixture count and access assumptions behind any per-square-foot estimate.
When permits and drain replacement add another charge
Some jurisdictions require a plumbing permit or inspection for a whole-home repipe, while minor repairs may be exempt. Permit and inspection charges commonly range from $0-$800, depending on local rules and project scope. A licensed plumber can verify requirements, but the homeowner should confirm whether the fee is included in the estimate.
Supply-line replacement does not necessarily include drain replacement. If aging drain, waste, and vent lines are also failing, adding that work may raise the project by $2,000-$8,000 or more, depending on pipe type, access, and how much of the system is involved. A sewer connection or underground line repair is usually a separate scope.
Code-required shutoff valves, pressure regulation, or other safety upgrades may add $100-$1,000 or more, depending on the number of locations and work required. Do not assume every older component must be replaced; ask the plumber to identify which items are required, damaged, or optional.
Have the estimate distinguish required code work from optional upgrades and separate supply piping from drains.
Which scope choices can lower the replacement bill
Replacing only the failed section can save money when the remaining lines are in good condition and the leak is clearly isolated. A partial repair may cost $1,000-$4,000, but repeated leaks, widespread corrosion, or brittle lines can make a whole-home repipe more economical than paying for multiple service calls. Ask for both repair and replacement options when the condition supports either choice.
Keep the scope focused. Reusing serviceable faucets, toilets, and water-heater equipment avoids replacement charges that are not necessary to restore the piping. Standard PEX is generally less expensive than copper, but the choice should fit local code and the home’s installation conditions. Avoid paying for premium fixtures or unrelated remodeling within a plumbing bid.
Clear access to cabinets, utility areas, and existing panels before the crew arrives. Confirm whether the homeowner can remove stored items or handle simple cleanup, but leave pipe work and regulated plumbing tasks to qualified workers. Compare at least three itemized bids that describe the same fixture count, pipe material, and restoration allowance.
Schedule nonemergency work when contractors have availability, if leaking conditions allow it. Emergency or after-hours service can add roughly $150-$500 or more in fees, and active water damage may make waiting unsafe. Ask what is included in the warranty and whether labor or materials are covered separately.
The largest controllable savings usually come from matching the repair scope to the actual pipe condition and comparing equivalent bids.
