Every kind of leak we locate and repair
One trade, one job: work out exactly where water or gas is escaping, prove it, then fix it
properly. Pick the situation that sounds like yours.
A water meter that keeps ticking with every tap shut off means water is going somewhere. We find exactly where, before anybody opens a wall.
Under-slab leaks in DeKalb are usually under a basement floor, not under a house. Same physics, same tools, and the same rule: locate first, break concrete once.
The line between your meter and your house is your responsibility, it is buried below the frost line, and it is the leak nobody sees until the water bill or the soggy parkway gives it away.
A sewer line does not leak out under pressure — it leaks out slowly and lets groundwater and roots in. The camera tells you which, and where, and how bad.
Read this first: if you smell gas, do not investigate it. Get everyone out, then call 911 and Nicor Gas from outside.
In a short northern Illinois swim season, a leaking pool wastes water, chemicals and heat all at once — and undermines the deck while it does it.
A wet basement floor has four possible causes and four completely different fixes. Paying for the wrong one is the most common mistake homeowners here make.
Water is running right now. Here is exactly what to do in the next five minutes, then call us.
Finding the leak is half the work. The other half is choosing a repair that lasts longer than the next winter.
Water on the floor by the heater is not automatically a dead tank. Four of the five likely sources are inexpensive fixes.
An irrigation leak is the easiest leak in a DeKalb yard to ignore, because a wet lawn in July looks like a working sprinkler system.
Commercial leaks cost twice: the water and the downtime. Our job is to keep the second number near zero.
How we work a leak call
1
You tell us what you're seeing
Most of the diagnosis starts on the phone. A warm patch on the basement floor, a bill that jumped, a sump running in dry weather and a ceiling stain are four different problems, and knowing which one you have shapes what we bring.
2
We prove there is a leak and size it
A timed meter test with the house isolated, then again with the main closed. Fifteen minutes, and it tells us whether water is escaping inside the building or out in the buried service line.
3
We isolate down to a branch
Hot against cold, upstairs against down, irrigation against domestic. Valves do a lot of work before any instrument comes out of the case.
4
We pinpoint with instruments
Ground and wall microphones, hydrogen-nitrogen tracer gas, thermal imaging, line tracing, correlation and sewer camera — whichever combination the situation calls for.
5
Two methods have to agree
We don’t mark a spot on one reading. When the acoustic peak and the thermal or gas result land on the same square foot, we mark it, photograph it, and show you the evidence.
6
We repair, test and document
Most repairs happen on the same visit. You get photos, the failure mechanism in writing, and a pressure-test result before anything is closed up.
What makes DeKalb plumbing fail
Leak work is local. The failures we see here come from a specific combination of climate, soil, water chemistry and housing stock, and knowing that pattern is most of what makes a locate fast.
Freeze-thaw, not just freeze
January averages a low near 13°F and the record is 27 below. Lines in rim joists, exterior walls, crawl spaces and garages split during a cold snap and then leak days later on the thaw — which is why our busiest week is usually after the cold breaks, not during it.
Clay till that moves
The glacial soil under DeKalb County holds water, swells, and shrinks again in a dry August. That slow seasonal movement stresses buried service lines, sewer laterals and the joints where pipe passes through a foundation. It also spreads leaking water sideways, so what surfaces is rarely above the break.
A century of housing in one city
Galvanized steel near the campus and the older downtown blocks, mid-century copper through the middle ring, CPVC and polybutylene from the 70s and 80s, PEX in everything built off Rich Road, Bethany Road and Dresser Road since the 1990s. Each material fails its own way, and the first question on any job is which one you actually have.
Deep-well water and household softeners
The city draws from deep sandstone wells and treats with ion exchange softening and iron filtration. That handles a lot, but private softeners, aging water heaters and long dead-leg runs still scale and accelerate pinhole corrosion at fittings.

Why homeowners here call us instead of guessing
The alternative to leak detection isn’t nothing — it’s demolition. Opening drywall until water appears, or trenching a lawn on a hunch, costs more than the locate does and frequently misses. Our whole argument is that a locate costs a fraction of the excavation or demolition it replaces, and it does not miss.
- We’ll tell you when you don’t need us. A toilet flapper, a softener stuck in regeneration, a downspout dumping at the foundation — if that’s the answer, you get the answer and a diagnostic charge, not a project.
- We price before we start. Including the after-hours premium, which you hear on the phone rather than on the invoice.
- We document for insurance. Illinois policies turn on sudden versus gradual. Our reports describe the failure mechanism, with dated photos and moisture readings, because that distinction decides claims.
- We stay in our lane. Exterior waterproofing excavation, liner replacement, fire suppression alterations — we’ll refer you rather than stretch into work that isn’t ours.
Leak detection questions from DeKalb homeowners
Shut off every fixture and appliance that uses water, including the ice maker and irrigation, then watch your water meter's low-flow indicator for thirty minutes. Any movement means water is escaping. Close the main shutoff at the house and repeat: if the meter still moves, the leak is in the buried service line. Our step-by-step meter test guide walks through it.
We quote on the call, before we come out, once we know what we are dealing with. The price depends on the size of the property, how much of the system has to be isolated and which instruments the job needs. There are no surprises added afterward, and the detection fee comes off the repair when we carry it out.
Yes, for leak emergencies, every night including holidays. There's a call-out premium for overnight and holiday response and we tell you the number before dispatching, not after arriving.
That's the entire service. Acoustic listening, tracer gas, thermal imaging and pressure isolation are all non-invasive. We only open an access point once two independent methods agree on a location, and that access is a single patch rather than exploratory holes.
Shut the main valve where the service line enters the house, usually on the basement wall facing the street. Open the lowest faucets to drain the pressure. Cut power to the area at the breaker if water is near electrical — only if you can reach the panel safely. Then call us. If the valve won't close, the City of DeKalb Water Division can shut the curb stop at 815-748-2050.
Not first. Leave the building immediately without touching switches or phones indoors, then call 911 and Nicor Gas at 888-642-6748 from outside. They respond 24 hours at no charge and their responsibility runs to the meter. Call us afterward to test, locate and repair the house piping.
Regularly. Apartment buildings and student housing near the NIU campus, retail and restaurants along Lincoln Highway and Sycamore Road, offices, schools and light industrial. We coordinate tenant access, provide certificates of insurance and schedule after hours where a shutdown would be costly.
Yes. Plumbing work in Illinois is licensed work, and we pull permits and schedule inspections with the City of DeKalb's Community Development Department where the job requires it.
