About Hushwell
Leak detection in Mount Prospect starts with which water it is. In a house with a basement, a wet floor has three possible sources — the supply, a drain or the sewer, and the ground — and only the supply is a pressurized pipe that can be listened for. Sewer backups and seepage are real problems, but they are not ours to locate, and hearing that on the first call saves a visit. After that, the B-box says whose line it is and the meter in the basement says whether the leak is past it.
Where a house has a basement, water on the floor can come from the supply, a drain, the sewer or the ground. Only the supply is a pipe we listen for, so that gets settled first.

The route
Which water it is and whose side of the B-box, settled before any search is priced.
Tell us when the water shows up
With rain, in dry weather, from the floor drain, or on a wall upstairs. That one answer sorts most calls into supply, sewer or groundwater before a visit is booked, and it costs nothing.
Read the meter in the basement
Every fixture off, then watch the low-flow dial. Turning means a leak in the plumbing past the meter. Still means any supply leak is on the buried stretch before it, or there is none at all.
We isolate, then search
Valves and the meter narrow the house to one section. Then acoustic gear, a thermal camera, a pressure test or tracer gas finds the spot inside that section.
You get the spot marked and written down
A mark on the spot, the reading that found it, and which side of the B-box it falls. The repair comes as a separate written quote, and you are free to give the finding to any licensed plumber.
Before you choose
None of them asks you to take anything on trust; each asks how the answer was reached, which you can check.
Did they ask whether the water comes with rain?
It separates a plumbing leak from groundwater or a sewer backup, and in a village with combined sewers it belongs in the first minute of the call.
Do they know which side of the B-box is yours?
A locate that never settles which side the leak is on can leave you paying to find a fault the village owns.
Is the locate priced apart from the repair?
An estimated $150 to $400 to find it, and a separate written quote to fix it, so the finding can go to any plumber.
Will they say so when it is not a pipe?
Seepage is a foundation job and a backup is a sewer job. Saying so on the phone costs us a visit, which makes it a fair test.
A pipe that split in January often shows itself in April, when the hose goes back on.
Where we work
Mount Prospect and ten of its neighborhoods. What changes street to street is the age of the house, its flood record and who supplies the water.
Questions

Something not covered here?
Put it to us by phone. Plain answers, an estimated range and nothing to sign.
Call (847) 994-0832By narrowing before listening: valves and the meter isolate a section, then the right instrument finds the spot inside it.
Locating usually fits in one visit; the repair is quoted after, once the spot is known.
Typically an estimated $150 to $400, with the repair as a second, separate quote. Where the buried service line is hard to reach, an estimated $300 to $800 is realistic. Nobody has verified a Mount Prospect average, so none is printed here.
Start with which water it is. With every fixture off, watch the low-flow dial on the basement meter: turning means a leak past it. If it is still and water keeps appearing, rain points at the ground, the floor drain at the sewer, and the wall where the service enters at your buried line.
Here the line runs the other way round. The village owns the main and the line out to the B-box; the owner owns it from the B-box to the meter inside the house, and everything after. Illinois American Water customers should ask that utility how its line is split.
