How repiping is done properly
Repiping & Pipe Repair is handled by independent licensed plumbers in Illinois. This page covers what the work involves, what changes the price, and the Illinois code and permit rules that apply. Published ranges are on the separate repiping costs page. Locally, the biggest markets for it are Chicago, Aurora, Springfield. Requests for it often arrive alongside plumbing inspection.
- 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

| Pressure testing the finished system and reconnecting all fixtures | Temporary lodging or a bypass supply while the house lacks water |
| Mapping the existing system and planning the new pipe routes | Drywall, plaster or tile restoration, texturing and repainting after the work |

Before you sign
Questions to ask before authorizing repiping
- 01
Will every fixture, hose bib and appliance line be reconnected, including the water heater, ice maker and outdoor spigots?
- 02
Is the main shut-off, pressure regulator and service line included, because leaving old components upstream undermines the new system?
- 03
Which pipe material is proposed for the new distribution lines, and how does that material perform with local water chemistry?
- 04
How many days will water be shut off, and will a temporary supply keep at least one bathroom usable overnight?

- What to ask for: the license number, the registered name behind it, and an insurance certificate issued to the property address.
Answers first
Repiping in Illinois — asked and answered
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 information speeds up a repiping callback?
Three things: where the water or problem is showing, whether the supply is shut off, and the property type — slab, crawl space or basement. With those, a pro covering Illinois can triage the urgency and bring the right parts.
How should a repiping quote be compared?
Line by line against scope: what is included, what is excluded, who pulls the permit, and whether haul-away and restoration are inside the number. The cost guides on this site list published third-party ranges so any quote can be sanity-checked.
Who handles the permit for repiping in Illinois?
The licensed contractor pulls the permit — never the homeowner. If a contractor proposes skipping a required permit, treat that as the signal to stop and verify the license.
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.
