The Illinois picture

Illinois' Lead Service Line Replacement and Notification Act requires every community water supply to inventory its service lines and replace lead ones on a state-mandated schedule. Two practical consequences for homeowners: your municipality can tell you what your line is made of, and full replacement — not partial — is the standard when work happens. Many suburbs coordinate replacements with water-main projects, which is often when the cost-sharing is most generous.

Where we come in

Remodels are where lead lines get discovered — kitchen and bath projects expose the plumbing, and permit inspections check service-line material against the municipal inventory. When that happens on a GS project in Northbrook, we flag it early, point you at the program above before anyone spends your money, run the replacement through our Illinois-licensed plumbing and excavation partners, and restore everything the dig touched.

GS Construction & Remodeling is a licensed general contractor, not a municipal agency. Program details above summarize official municipal sources and change over time — confirm current terms with Northbrook before making decisions based on them.

How do I find out if my Northbrook home has a lead water line?

Does GS Construction replace lead service lines?

Service-line replacement itself is licensed plumbing and excavation work — on GS projects it runs through our Illinois-licensed plumbing and excavation partners, and we handle what comes after: restoring the yard, landscaping edges, and any interior finishes the work touched. If a remodel uncovers a lead line, we flag it and point you at the municipal program before anyone spends your money.

Why do lead lines come up during remodels?

Kitchen and bathroom remodels expose the plumbing where it enters the home, and permit inspections increasingly check service-line material against the municipal inventory Illinois law requires. Finding out mid-project is normal — knowing your village's program before demo day is better.
