Leak Detection in Iowa
Leak Detection across Iowa: the 150 ZIP codes and 74 cities we route calls in, and who licenses plumbers in the state.

Free to homeowners in Iowa — the contractor pays us for the introduction, you never do.
Where we listen
Our leak detection coverage in Iowa runs to 150 ZIP codes in 74 cities. Where covered places are small and the service runs are short, a leak that does not show at a fixture is usually within a few meters of the house — under a slab, a porch or a drive — and the meter test that finds it takes minutes rather than a day.

What this site is
AcousticLeak is a referral service, not a contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands. We carry out no work and no leak location, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call. Nothing here is a statement about what your own utility will credit; only your utility can tell you that.Checking a credential in Iowa
Iowa licenses are issued by the Iowa Plumbing and Mechanical Systems Board, which publishes a public search you can use before work begins.

What that coverage looks like
Des Moines alone accounts for 55 of the state's 150 covered ZIP codes, and Polk County for 62. Dense coverage like that is where a leak call is answered quickest; the 18 counties behind it are where the drive time starts to matter, and where locating the leak precisely before anyone is dispatched saves the most.
How a leak detection job goes
A leak you cannot see is found with sound and with pressure, not by digging until something turns up. The meter is isolated and watched, the run is listened along, and the point is marked before any surface is opened. What that is worth is simple arithmetic: the cost of locating is fixed, and the cost of opening the wrong three meters of concrete is not.
What the call asks about leak detection
- Whether the meter moves with every tap in the house shut off — that one test separates a leak from a fitting.
- Where the water is showing, if it is showing at all: a ceiling, a wall, a warm patch on a floor, or only the bill.
- Whether the house is on a slab, a crawl space or a basement, because that decides how the run is reached.
