First, the answer
Published third-party data puts repiping in the 1,500–15,000 dollar range nationally — Labor is the majority of a repipe, so house size, stories and how much wall has to be opened matter more to the total than the pipe material itself. Every contractor prices independently, so treat that as a sanity check on a quote rather than a quote itself. The work itself is described under repiping & pipe repair, and the number that ends up on the invoice comes from licensed plumbers in Illinois, not from this page. Local pages start with Lombard.
What the data shows — reported ranges for repiping in Illinois
| Job | Reported range | What pushes it higher |
|---|---|---|
| PEX pipe, per linear foot | $0.40–$2 | Fitting type, oxygen-barrier grades and manifold layouts change the material line. |
| CPVC pipe, per linear foot | $0.50–$1 | Solvent-weld joints and support spacing in hot-water runs add fitting labor. |
| Copper pipe, per linear foot | $2–$8 | Commodity price moves and soldered joints in tight ceiling voids drive this up. |
| Whole-house repipe, published outer bounds | $1,250–$22,000 | Number of bathrooms, stories, slab construction and finished surfaces to reinstate. |
| Mobile home repipe | $1,500–$4,000 | Under-floor access, skirting removal and non-standard pipe sizes on older units. |
| Permits | $50–$500 | Jurisdictions that require separate rough-in and final inspections charge at each stage. |
| Making good drywall afterwards | $300–$900 | Number of access openings, textured finishes and whole-wall repainting rather than patching. |
Not a quote. These are third-party reported ranges, sourced from Angi, "How Much Does It Cost to Repipe a House? [2026 Data]", angi.com/articles/cost-to-repipe-a-house.htm, fetched 2026-08-11. Only a licensed contractor who has seen the job can price it.
Where the money goes — the 6 factors that change the number
Pricing is set independently by each contractor, so this page lists what moves the number rather than a figure.

Number of fixtures, bathrooms and stories
- 02
Pipe material chosen
- 03
Slab versus crawl space versus accessible basement routing
- 04
How much drywall, tile or plaster must be opened and restored
- 05
Whether the water service line and main shut-off are replaced at the same time

Permit and inspection requirements
How it shows up — is repiping actually the fix?
Paying for the wrong job is the most expensive mistake here. These are the signs that point to repiping rather than something else.
- Rusty or discolored water at multiple fixtures
- Repeated pinhole leaks in the same system
- House-wide low water pressure
- Known polybutylene or galvanized steel supply piping
- A pipe has burst after freezing
What the work involves — so a quote can be read line by line
- The existing system is mapped and material and condition documented
- Pipe material and routing are selected (PEX, copper, CPVC)
- Permits are pulled and the work is staged to limit water-off time
- New lines are run, fixtures reconnected, and the system pressure-tested
- Openings are patched and the work is inspected
Repiping cost by city in Illinois
Labor rates, permit fees and travel distance all differ across Illinois, which is why the same job is not the same number in every market.
| City | County | Permit authority |
|---|---|---|
| Repiping in Chicago | Cook County | Chicago Department of Buildings |
| Repiping in Aurora | Kane County | Aurora Building & Permits |
| Repiping in Springfield | Sangamon County | Set locally |
Before anyone touches a pipe
Verify the license. It takes two minutes.
- Who licenses the work: Illinois Department of Public Health (IDPH) together with the local jurisdiction.
- Who pulls the permit: the licensed contractor, never the homeowner.
- What to ask for: the license number, the registered name behind it, and an insurance certificate issued to the property address.
How to avoid overpaying for repiping
- Get the scope in writing before the number: what is being replaced, what is being repaired, what is being left alone.
- Ask whether the price is flat-rate or time-and-materials, and what the diagnostic charge covers.
- Ask whether the permit and inspection fee is inside or outside the figure.
- Ask what happens if the job opens up and turns out to be larger — get the change-order rule up front.
- Confirm the warranty term on parts and on labor separately.
- Verify the license number on the IDPH register before any work starts.
Answers first
Asked and answered — repiping cost in Illinois
How do I know if my house needs repiping?
The usual triggers are the material itself (galvanized steel or polybutylene), repeated pinhole leaks across the system rather than at one spot, and discolored water at multiple fixtures. One leak in one place is a repair; a pattern across the house is a repipe conversation.
PEX or copper?
PEX installs faster, costs less in labor, tolerates freezing better and has fewer joints in walls. Copper has a longer track record and is preferred by some jurisdictions and some buyers. Local code, water chemistry and your resale plans all factor in — ask the contractor to justify the choice for your specific house.
How long does a whole-house repipe take?
For a typical single-family home, commonly a few days of pipe work plus separate drywall repair and inspection. Water is usually off only for part of each working day rather than continuously.
What warranty applies to the work?
Whatever the contractor offers in writing — PlumberIllinois is not a party to the agreement. Ask for labor and parts warranty terms in the quote, and keep the license number with the paperwork.
How does the callback request work?
The 30-second form asks for a name, ZIP and the number to reach you on. The request routes to an independent licensed professional covering that area, and they call you back. Consent for marketing contact is optional — the request goes through with or without it.
Which areas does PlumberIllinois cover?
All of Illinois: the site lists every covered city with real ZIP codes, the county permit authority and nearby coverage, so requests route to a professional already working that area.
Is PlumberIllinois a plumbing company?
No. Independent licensed professionals perform and contract the work directly with you. PlumberIllinois routes the request and links every page to the official Illinois license register.
Does PlumberIllinois charge homeowners anything?
No. PlumberIllinois may be compensated by a partner when a homeowner connects with a professional through the site. That never changes what the contractor charges for the job.
