How Much Does It Cost to Repipe a House in Chicago, IL? [2026 Data]

Chicago’s higher labor costs push repiping prices slightly above the average nationwide. The average Chicago cost to repipe a house ranges between $1,554 and $15,540, with most homeowners paying around $7,770, depending on factors like pipe material, home layout, and installation complexity. Here’s what to expect from repiping costs in the Windy City. 

House Repiping Cost Factors 

These are the main factors to consider when budgeting to repipe a house in Chicago, IL.

Size

Large homes have more plumbing fixtures and require longer runs for pipes and drain lines, so they cost more to repipe. Additionally, multistory homes cost more to repipe than single-story homes because you'll need more piping material to reach plumbing fixtures between floors.

Materials

There are three main types of plumbing pipe materials: copper, CPVC, and PEX. Costs vary with the material. For instance, copper ranges from $3 to $9 per linear foot, while CPVC costs around $1 to $2 per linear foot.

Remember that local codes can dictate the types of pipes you can use. Your plumber can recommend the best material for your home.

Number of Plumbing Fixtures

Proper piping is required for all of your home's fixtures, including toilets, sinks, and showers. The more fixtures you have, the more piping you'll need. Rough-in plumbing for a bathroom is costly, as getting pipes to precise locations is more labor-intensive than running plumbing behind walls. If you’re changing your home’s layout, expect to pay more for the total cost.

Diameter of Piping 

The size, or diameter, of your pipes also affects costs. Pipes used for waste drainage are wider than pipes designed to carry water. For the same type of piping, larger diameters will be more expensive. However, most drain lines consist of PVC, which is less expensive than copper, so drainpipes should still be more affordable than water supply lines.

Accessibility

If your pipes are in a difficult-to-reach location, expect to pay more for repiping your house. For example, pipes under concrete are more difficult to access than pipes behind drywall, so they cost significantly more to remove and replace.

Inspection Cost

If your municipality requires a permit for repiping, you’ll need an inspection after the work is done to ensure everything is up to code. In most cases, the initial inspection cost is included in the permit fee. However, reinspection costs around $25 to $155 if an issue requires it.

Soil Conditions

The soil around your home can also affect the cost of repiping. For example, clay soil shifts over time, affecting the surrounding plumbing and leading to more costly installations. This is only a factor if you replace buried lines, like water mains, underground pool lines, and sprinkler lines.

Plumbing Pro Costs

Hiring a professional plumber is essential for this project to ensure everything is installed properly and up to code. These are the factors that impact the labor costs on your final bill.

Local Labor Rates

Plumbers across the U.S. charge between $45 and $200 per hour. Plumbers in Chicago typically charge between $45 and $210 per hour due to higher labor demand and operating costs throughout the city.

Permits

Repiping a house requires a plumbing permit from the City of Chicago, which can only be obtained by a licensed plumber. Before work starts, confirm whether permit and inspection costs are included in your plumber’s estimate.

Taxes

Materials used for your home repiping project are subject to Chicago’s combined sales tax rate of 10.25%. These costs will typically be accounted for in your estimate.

Additional Pros to Consider Hiring 

Along with a professional plumber, you may need to hire additional contractors to open and repair walls, ceilings, or flooring after the new piping is installed. Also, if there’s water damage or mold, you might need to bring in a water damage restoration or mold remediation specialist.

Here are some common professionals involved in repiping projects and their typical costs: 

• Water damage repair specialist cost: $1,380–$6,380

• Drywall repair contractor cost: $300–$930

• Ceiling repair contractor cost: $440–$1,730

• Mold remediation specialist cost: $1,220–$3,760

• Flooring repair contractor cost: $500–$3,000

• General contractor cost: $50–$150 per hour

Does Repiping a House Increase Home Value?

The ROI of repiping a house won’t likely show up as a higher selling price on the Chicago market, but it can still play a major role in protecting your resale value and helping your home sell faster.

While buyers might not initially notice worn or damaged pipes, these are frequently flagged during inspections and can quickly become a negotiation point. Buyers may ask sellers to complete repairs before closing, provide credits for future plumbing work, or reduce the purchase price to offset the cost of repiping after move-in. A functional and modern plumbing pipe system tells buyers the home is move-in ready, helping preserve your asking price and close the sale without hurting your bottom line.

How Angi Gets Its Local Cost Data 

To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.

Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.
