Before you sign

What to ask a New Lenox contractor first

01
For a slab leak, is a spot repair through the concrete or an overhead reroute proposed, and why that choice?
02
Will a written report with photographs and marked locations be provided, since insurers usually require proof of cause and position?
03
Which detection methods are included — acoustic listening, thermal imaging, tracer gas or a meter isolation test — and in what order?

Local factor

The largest lead service line inventory in the country

Chicago has more lead service lines than any other city in the United States, and under the 2024 federal Lead and Copper Rule Improvements it was granted a 20-year replacement window instead of the standard 10 because of that scale, with reporting indicating the city's own plan runs longer still. Illinois also has its own Lead Service Line Replacement and Notification Act requiring systems to inventory lines and notify property owners. For a homeowner the practical points are that the utility's record for an address may be listed as unknown or simply wrong, that any job which exposes the service line is a free chance to identify the material, and that a partial replacement can temporarily increase lead release - so full-line replacement, coordinated with the utility, is the goal.

Answers first

Leak Detection in New Lenox — common questions

How do I know if I have a hidden leak?

The simplest test: turn off every fixture and appliance that uses water, then watch the water meter's low-flow indicator for 15–20 minutes. Any movement means water is leaving the system somewhere. That test does not tell you where — it tells you that detection is worth paying for.

Is a slab leak an emergency?

It is urgent rather than instantaneous. A slab leak will keep eroding fill under the foundation and driving up the bill for as long as it runs, so it should be located quickly — but you generally have hours to days, not minutes, unless water is entering the living space.

Will detection damage my floor?

Modern detection is designed to avoid that: the point of acoustic, thermal and tracer-gas equipment is to make one small opening instead of several exploratory ones. Ask the contractor what restoration is and is not included before work starts.

Do I need a permit for plumbing work in New Lenox?

Permit requirements around New Lenox are set locally rather than statewide. As a rule, water heater replacement, gas work, sewer laterals and repiping are permitted work, while a like-for-like faucet or disposal swap usually is not. A licensed contractor pulls the permit — if one offers to skip it, that is the signal to stop.

How should a leak detection 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 leak detection 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.
