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 Lake Bluff, 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 Lake Bluff before making decisions based on them.

- How do I find out if my Lake Bluff home has a lead water line?
-
Review the "Service Line Inventory" document (as of April 2026) posted on the Village website; the Village also sent letters to properties identified with suspected/known lead lines. Residents with concerns who did not receive a letter can contact Village Engineer Jeff Hansen at 847-283-6884; the Village also suggests confirmation by a certified plumber.
- 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.
