Warning Signs
Signs You Have a Hidden Water Leak
Not every leak shows itself. Here is what to watch for before it becomes a bigger problem. Our acoustic and thermal detection equipment finds leaks inside walls, under slabs, and underground — without tearing anything open first.
Water meter keeps running after you shut everything off inside
A spinning meter with all fixtures off means active water loss — underground, slab, or supply line failure. Do the meter test right now.
Your utility sent you a high-usage alert
Fort Collins Utilities, WMWD, PA American Water, Snohomish PUD — when they flag unusual consumption, that alert is a confirmed signal, not a reason to wait.
Water bill went up $100 or more with no change in habits
A 1 gallon-per-minute leak wastes 43,000 gallons a month. One detection call pays for itself in the first billing cycle after repair.
Wet spot on ceiling, wall, or floor with no obvious source
Water travels before it appears. The stain on your ceiling is rarely where the leak is. Thermal imaging traces the moisture path to the exact source.
Warm or soft patch on your concrete floor
A warm spot on a slab floor is one of the strongest indicators of a hot-water slab leak. Thermal imaging confirms it in minutes without breaking concrete.
Green patch or weeds growing over your water line in the yard
Underground leaks feed the root zone. A strip of unusually green or thriving vegetation directly over your service line is a classic underground leak sign.
Low water pressure at fixtures throughout the house
Pressure drop across multiple fixtures simultaneously — not just one — usually points to a supply line failure rather than a fixture issue.
Musty smell or damp feeling in a room with no visible moisture
Moisture behind walls and in crawl spaces produces mold within 48–72 hours. A musty smell with no visible source means moisture is inside the structure.
Seeing one of these signs? The longer you wait, the more it costs.

How We Find Leaks
Four Detection Methods. No Guesswork.
We choose the right equipment based on where the leak is and what type of line is involved. No exploratory demolition — we confirm the location first.
01
Acoustic Leak Detection
Ground microphones and listening devices amplify the sound of water escaping a pressurized pipe — through concrete, packed soil, and walls. We hear the leak before we touch anything.
02
Thermal Imaging
Infrared cameras detect temperature differences caused by moisture behind walls or under floors. No cutting, no guessing — we see exactly where the moisture is concentrated.
03
Pressure Testing
We isolate sections of your line and test for pressure drop. This confirms a leak exists and narrows the location precisely before any excavation or wall access happens.
04
Tracer Gas Detection
For deep underground lines, we introduce non-toxic tracer gas into the pipe. It escapes at the leak point, rises to the surface, and our detector picks it up — accurate to within inches.

FAQ
Frequently Asked Questions — Leak Detection
Real questions from homeowners who called us.
This almost always means an underground leak — in your service line between the meter and your foundation, or in buried irrigation lines. There is no visible indoor moisture with these leaks. Acoustic detection and pressure testing locate the source without excavating your entire yard first.
Yes. Acoustic detection, thermal imaging, and tracer gas testing locate leaks inside slabs, behind walls, and underground without any destructive access. We confirm the exact location first. Concrete cutting or wall access only happens after we know precisely where the leak is — never before.
Both. After locating the leak, we give you a clear diagnosis and a fixed price for the repair. Most customers have us handle detection and repair in the same visit. One company, one call — the person who found it fixes it. No coordinating a second crew or waiting another day.
This is one of the most common calls we get. General plumbers often do not carry acoustic or thermal detection equipment. We specialize only in leaks and use equipment built for this job. If another plumber could not locate it, our detection tools can — that is the entire reason we exist.
Residential leak detection typically runs $150 to $400 depending on property size and the number of lines being tested. We quote the detection fee before we start — and in most cases, that cost is applied toward the repair when booked same day.
Most residential visits take one to two hours. Underground and slab jobs with multiple lines may take longer. We give you an expected timeframe when you call so you can plan around it. If we are doing the repair same day, we update the timeline after diagnosis.
