Answers to the most common questions about lead pipes, water safety, replacement costs, and available financial programs.
Expert answers from licensed plumbers on identification, health concerns, and every available replacement program.
Homes built before 1986 in Chicago and many surrounding suburbs commonly have lead service lines. The easiest way to check is to inspect the pipe where it enters your basement or crawl space. Lead pipes are dull gray, soft, and will turn shiny silver when scratched with a coin. A magnet will not stick to lead. If you’re unsure, schedule a professional inspection.
Lead service lines often fail due to age or corrosion. Warning signs include:
-
Unexplained drops in water pressure
-
Repeated leaks in the service line
-
Constantly discolored water
-
Visible corrosion at the pipe entry point
If the line breaks, the City of Chicago will replace it for free.
The public side runs from the water main to the property line.
The private side runs from the property line into the home.
A proper replacement removes both sections of lead pipe to eliminate lead exposure.
Most standard homeowner insurance policies do not cover replacement of lead service lines. Some policies may cover water damage from leaks but not the pipe replacement itself. Always check your policy or call your agent.
If your home has a confirmed lead service line, the sooner you replace it, the safer your drinking water will be. Many families choose replacement immediately if children, infants, or pregnant women live in the home. If a grant or subsidy is available, take advantage of it as early as possible.
Yes. Lead can leach into drinking water, especially when pipes corrode or water sits in the line for long periods. Even low levels of lead exposure can affect children’s development and may cause long-term health issues in adults. The safest option is full replacement of the lead service line.
The physical replacement usually takes 4–8 hours. Excavation, installation, reconnection, and site restoration are typically completed in one day. Larger properties or difficult access may require additional time.
Replacement typically ranges from $12,000 to $25,000 depending on pipe length, access, and restoration needs. However, many Chicago homeowners qualify for free or heavily subsidized replacement through city and state programs.
Yes. Chicago’s Equity Lead Service Line Replacement Program provides free full replacements for income-eligible, owner-occupied homes — including both the private and public sides of the line. There are also free replacements for line breaks, daycare facilities, and blocks undergoing water-main upgrades. For more information check out Chicago's Lead-Safe Chicago website.
Chicago offers a permit fee waiver program for homeowners who hire a private contractor — saving thousands. Some suburbs provide rebates or partial reimbursements, and Illinois EPA offers low-interest financing options in certain areas. A professional can help determine which programs you qualify for.
Yes, temporarily. Water service is typically shut off for 2–6 hours while the old pipe is removed and the new copper line is installed. Water is restored the same day.
Most projects require excavation at the parkway and inside your property to reach the old line. After installation, landscaping, soil, and concrete are restored. Contractors will inform you in advance if a sidewalk slab or driveway section needs replacement.
It’s possible but strongly discouraged. Replacing only half of the pipe leaves part of the lead line in place and may actually increase lead levels temporarily. Chicago programs typically require full replacement for safety.
