Sometimes the hardest part of a hidden leak is making sense of the clues. Our diagnostic assessment brings together your symptoms, the plumbing layout, and test results to determine what is happening and where — and explains it in plain language.
A diagnostic assessment is a good starting point when the situation is unclear:
If you are not sure whether you need a slab leak specialist at all, start with our guide to checking for unexplained water usage.
This is our most structured service. Rather than starting with a single tool, it works through the problem step by step:
Moisture readings and thermal images are useful supporting evidence, but neither proves a leak on its own. Thermal camera maker Teledyne FLIR notes that a pattern that looks like moisture does not guarantee water is present, which is why we cross-check results.
Honest about limitations. A diagnostic assessment gives you the best available picture based on the evidence, but some situations — very small or intermittent leaks, for instance — can remain uncertain. If so, we will explain what we found and what further testing could help.
Accurate detection gives you better information before any repair decision.
Useful for repair contractors, property owners, and conversations with your insurer.
Knowing what is not the problem is as valuable as knowing what is.
We explain the evidence and our confidence level — no jargon.
Homeowners and property managers share how our detailed diagnostic findings provided clarity and peace of mind.
“We were caught in a stressful dispute between our HOA, our insurer, and two plumbers who had conflicting theories on what was causing subterranean dampness in our common foundation. Precision conducted a meticulous diagnostic assessment, ruling out exterior drainage and isolating an active pressurized supply branch. Their written diagnostic report provided indisputable proof that resolved the claim immediately.”
“After getting hit with a $400 water bill, I feared the worst. Precision's technician didn't just rush in with one gadget — he systematically checked meter flow, isolated irrigation and interior loops, cross-checked thermal gradients, and confirmed the leak location acoustically. The written explanation was crystal clear with zero high-pressure sales. Top tier professionalism.”
A step-by-step approach from your first call to clear findings.
Tell us what you are noticing, where, and when it started.
We review the symptoms and check fixtures, the water heater, and the meter.
We isolate lines and use suitable equipment to narrow down the leak area.
We explain what we found, how confident we are, and your options.
Common questions about leak location & diagnostic assessment.
Slab leak detection focuses on locating a suspected leak beneath the slab. A diagnostic assessment takes a broader view when the cause is unclear, working through symptoms and test results to determine what is happening — which may or may not be a slab leak.
Ask us when you call about the format of findings for your visit. Written notes are useful for repair contractors, property owners, and insurers.
Thermal imaging can be a helpful supporting tool, particularly for hot-water lines, when conditions suit it. It does not detect water directly, so we treat it as one piece of evidence alongside other methods. Ask us which methods suit your situation.
We work with homeowners, property managers, and commercial property owners. Call to describe the property and the concern so we can confirm scope and scheduling.
That is useful information. We will explain what was ruled out and where the evidence points instead — for example, a fixture, an irrigation line, or a drain — so you know who to call next.
