Not every water heater leak announces itself. Sometimes it's a musty smell in the utility closet, a warm spot on the garage floor, a water bill creeping upward, or condensation you can't explain. Our leak detection service finds the truth with moisture meters, thermal imaging, and systematic pressure testing — so you fix the real problem instead of replacing parts on a hunch.
Detection matters because the visible drip is often not the actual failure. We've traced "tank leaks" to sweating cold-water pipes, slab moisture wicking up, and condensate from oversized units — each with a very different (and cheaper) fix than a new water heater.
Active leak, no hot water, or gas smell — don't wait. Call Emergency Line
Survey: moisture meter readings across the area map the wet zone.
Thermal scan: infrared imaging reveals hidden hot-water paths behind walls and under slabs.
Confirm: the suspect fitting, valve, or tank section is pressure-tested to prove the source before any repair quote.
Storm-season note: after heavy rain, groundwater and humidity can mimic leak symptoms. Post-storm is our busiest detection season — we sort real plumbing leaks from storm-driven moisture so you only pay for what you actually need.

|---|---|
| Leak detection / service call | $89–$149 |

Ranges are representative market estimates for the DeSoto area and can vary by unit size, access, and parts. Final pricing is confirmed on-site before any work begins. Owner to verify.
Moisture meters, thermal cameras, and isolation testing — we pressurize sections of the system one at a time until the culprit reveals itself.
Very possible, especially on cold-water lines in humid months. Detection distinguishes the two, because the fixes are completely different.
If the tank is young and the leak is hidden, absolutely — finding a $200 fitting leak beats a $2,500 replacement you didn't need.
If the evidence points under the slab rather than at the heater, we'll tell you plainly and refer the right specialist — we don't sell you a water heater for a slab problem.
