We specialize in leaks only — not general plumbing, not HVAC. Every service below uses specialist detection equipment before anything is opened on your property.
Slab Leak Detection — DeKalb
DeKalb's heavy clay (Chicago plain) soil shifts seasonally — swelling and contracting with every moisture cycle. That movement puts constant lateral stress on copper supply lines running under basement foundations. Combine that with the corrosive effect of mineral-heavy water from DeKalb Water District and you get pinhole slab leaks in homes less than 20 years old. We use acoustic listening equipment and thermal imaging to locate the exact failure point before any concrete is cut.
Q: How do I know if I have a slab leak in my DeKalb home?
A: The clearest signs are a warm patch on your floor, running water sounds with everything off, or a high-usage alert from DeKalb Water District. In DeKalb's heavy clay (Chicago plain) conditions, slab leaks are more common than in markets with stable soil. We confirm with a pressure test in under an hour — before touching any concrete.
Underground Leak Detection — DeKalb
The DeKalb Water District meter is spinning but nothing inside is wet. That combination — active meter reading, dry house — almost always means an underground supply line leak between the meter and your foundation. In DeKalb's heavy clay (Chicago plain) conditions, that water drains away immediately without surfacing. Ground microphones, pressure isolation, and tracer gas locate the exact failure point without excavating your full yard.
Q: My DeKalb Water District meter is running but nothing inside is wet — where is the leak?
A: In DeKalb, this almost always means an underground supply line leak — between the meter and your foundation, or in a buried irrigation line. heavy clay (Chicago plain) conditions mean the water drains away without surfacing. Acoustic detection and pressure testing locate it without digging up your property.
Water Main & Service Line Repair — DeKalb
In Illinois, the water service line from the DeKalb Water District meter to your home is your responsibility — and your bill until it's repaired. Main line failures in DeKalb are most common in pre-1950 to 1970s galvanized and copper infrastructure and after periods of heavy clay (Chicago plain) soil movement. We locate the failure point, excavate only what's needed, and repair or replace the damaged section — detection and repair in one visit.
Q: Who owns the water line between the DeKalb Water District meter and my DeKalb home?
A: You do. DeKalb Water District owns the meter, but the service line from the meter to your foundation is the homeowner's responsibility in Illinois. A failure on that line is your repair — and every gallon lost counts against your bill until the repair is completed. We locate the failure and fix it in one visit.
Irrigation Leak Detection — DeKalb
DeKalb irrigation systems run under sustained pressure and fail silently underground — no wet surface, no pooling, just a DeKalb Water District bill that keeps climbing. heavy clay (Chicago plain) soil expansion cracks fittings and flex joints underground without any visible surface sign. We isolate and pressure-test each zone separately to find the failing section, then repair without unnecessary trenching.
Q: How do you find an underground irrigation leak in DeKalb?
A: Zone-by-zone pressure isolation and acoustic detection. In DeKalb's heavy clay (Chicago plain) conditions, irrigation water drains away immediately — no puddle, no obvious wet ground. We test each zone separately, identify which section is losing pressure, then use acoustic equipment to pinpoint the failure before we start digging.
Bathroom, Kitchen & Ceiling Leak Detection — DeKalb
Water stain on the ceiling below an upstairs bathroom. Soft spot in the subfloor next to the kitchen sink. Damp wall behind the shower that won't dry out. In DeKalb's basement construction, these moisture signs usually trace to a supply line fitting failure, a cracked drain connection, or a deteriorated shower pan. Thermal imaging locates the source without cutting walls blindly.
Q: I have a water stain or wet area near my bathroom — what's causing it in DeKalb?
A: In DeKalb's basement construction, bathroom moisture most commonly traces to a supply line fitting failure, a cracked drain connection, or a failed shower pan. Thermal imaging locates the source before we open anything. Call before you tear out tile or drywall — the visible stain is almost never at the actual leak location.
Gas Leak Detection — DeKalb
Natural gas and propane leaks in DeKalb homes occur at meter connections, appliance fittings, and buried supply lines. If you smell gas right now — leave immediately without touching any switches, call 911 from outside. Once the gas company clears the property, call us to locate the exact failure point before service is restored.
Q: What should I do if I suspect a gas leak in my DeKalb home?
A: Leave immediately without touching any switches or appliances. Call 911 from outside your property.

How We Find Leaks Without Tearing Up Your DeKalb Property
Four methods. We choose the right one based on the leak type, location, and DeKalb's specific soil and construction conditions — not a one-size-fits-all process.
Acoustic Leak Detection
Ground microphones amplify the sound of pressurized water escaping through heavy clay (Chicago plain) soil, concrete slab, and wall cavities. We hear the leak before we touch anything on your DeKalb property.
Thermal Imaging
Infrared cameras detect temperature differences caused by moisture behind basement walls and under floors. No cutting, no guessing — we see where the water is concentrated before opening anything.
Pressure Testing
We isolate sections of your supply line or irrigation zones and test for pressure drop. This confirms a leak exists and narrows its location before any excavation happens in DeKalb's heavy clay (Chicago plain) ground.
Tracer Gas Detection
For deep underground supply lines, we introduce non-toxic tracer gas into the pipe. It escapes at the failure point, rises through heavy clay (Chicago plain) soil, and our detector pinpoints the exact location — accurate to within inches.
Non-invasive detection — we find it before we open anything. Detection fee quoted upfront.

Why DeKalb Has Higher Leak Risk Than Most Markets
Northern Illinois's specific combination of soil type, construction era, and climate creates leak conditions that out-of-area services often misdiagnose. Here's what makes DeKalb different.
🌍 Northern Illinois Soil: Heavy clay (Chicago plain)
Chicago and Illinois suburbs have some of the most demanding soil conditions in the country — heavy clay that freezes to depth in winter. Homes in older Chicago neighborhoods commonly have original galvanized service lines from before 1960. Water main breaks are frequent in winter due to frozen ground pressure.
🏗 Construction Type: Basement
DeKalb is a small community with predominantly basement construction. In this construction type, supply line failures hide without visible surface signs until located with acoustic or thermal equipment.
🔧 Pipe Era: pre-1950 to 1970s galvanized and copper
Homes built in the pre-1950 to 1970s galvanized and copper period — common throughout DeKalb — have supply lines at or approaching end of designed service life. These lines corrode from the inside and fail silently before any surface sign appears at the wall or ceiling.
❄ Seasonal Risk in Northern Illinois
Illinois winters are severe — deep ground freezing causes service line breaks and forces emergency leak response throughout the winter months. Understanding this seasonal pattern is what separates a technician who knows DeKalb from one who's never worked in Northern Illinois before.
