You Might Have A Leak If...
A hidden leak rarely announces itself clearly, these are the real warning signs, and noticing more than one at the same time is a stronger signal than any single one alone. None of these guarantee a leak, but together they're worth a proper look before the damage becomes visible.
Unexplained High Water Bill
A bill that jumped with no obvious change in usage is the most common leak indicator we see.
Sound Of Running Water
Hearing water when every fixture is off often means a leak somewhere in the wall or slab.
Warm Spot On The Floor
A warm patch on an otherwise cool floor can mean a hot water line leaking under the slab.
Mold Or Musty Smell
A persistent musty smell with no visible source often traces back to a slow leak inside a wall.
Non-Invasive Detection
We find the leak before opening anything, not the other way around.
Electronic Acoustic Detection
Specialized listening equipment pinpoints the leak's location through walls, floors, and slabs.
Pressure Testing
Isolating sections of the plumbing system to confirm exactly where pressure is being lost.
Thermal Imaging
Temperature differences can reveal a hot water line leak invisible to the eye.
Minimal Access Points
Once located, we open only what's needed to reach the leak, not the whole wall or floor.
A Leak Detection Visit
We start with the symptoms you've noticed, a sound, a wet spot, a water bill spike, since that narrows where to begin listening. Acoustic detection equipment can pick up the specific sound water makes escaping a pressurized line, even through concrete or drywall, and pressure testing isolated sections of your plumbing confirms which part of the system is actually losing pressure.
Once we have a strong location, we'll mark it and explain what repair options exist before opening anything, so you understand the plan before any wall or floor gets touched.
Suspect A Hidden Leak?
Don't wait for it to get worse, call and we'll find it without guesswork.
The Cost Of Waiting
A slow, undetected leak doesn't just waste water, it can undermine a slab foundation, feed mold growth inside a wall cavity, or slowly corrode a section of pipe until it fails completely. Finding it early with proper detection equipment is almost always cheaper than dealing with what a leak causes after months of going unnoticed.
Where Leaks Tend To Hide In Sterling
All leak repairs, once located, are completed to Uniform Plumbing Code (UPC) standards, the same code our technicians follow on every job across Sterling.
Sterling's mixed-era construction means leak detection often starts with a different assumption depending on the home. In older sections, we're usually chasing a failing joint in aging galvanized or copper supply line.
In newer construction, a leak is more likely tied to a fitting or connection issue on PEX line rather than the pipe material itself failing. Knowing your home's approximate age before we arrive helps us bring the right detection approach.
What Leak Detection Typically Costs
Detection itself costs far less than the water damage a missed leak eventually causes.
Detection only. Repair quoted separately once the leak is located.
Catching a leak early through proper detection, rather than waiting for it to become visible, is consistently the cheaper and less disruptive path for homeowners.
Water Meter Running And You Can't Find The Leak?
Check the meter with every fixture, appliance and ice maker off. If the dial or flow indicator still moves, water is escaping between the meter and your fixtures. A bill that keeps creeping up, a soft spot in the yard or a stain on the ceiling points the same way.
If a plumber already looked and came up empty, that is a common reason people call us. We isolate the line with pressure testing, then narrow it with acoustic listening, plus thermal imaging when a hot line is suspected. The dispatcher gives a clear quote before any repair starts.
Can you fix it too?
Yes. The same licensed team repairs the leak once it is marked, so you do not need a second company.
Under concrete or a driveway
We locate it first, then talk through access, including trenchless options where they fit.
Rentals and small multifamily
Duplexes and triplexes take longer to isolate unit by unit. Tell the dispatcher how many units share the line.
House on the market
If an inspection flagged moisture or a buyer is waiting, say so on the call so scheduling can reflect it.
Leak Detection Questions
What Sterling homeowners ask before scheduling a leak detection visit, especially about how invasive it will be.
Will you have to cut into my wall or floor?
Detection itself is non-invasive. We only open what's needed once the leak is precisely located, minimizing repair work afterward.
How accurate is electronic leak detection?
Very, in most cases we can pinpoint a leak's location within inches before any exploratory opening is made.
What if it turns out to be a slab leak?
We'll walk you through repair options, including trenchless approaches, once the leak is confirmed and located.
Do you offer camera footage of the leak location?
We can show you the detection readings and explain what they mean, though the leak itself isn't visible until the repair opens that section.
My water meter keeps running with everything off. Is that a leak?
Usually yes. When every fixture is off and the meter still moves, water is leaving the system somewhere. It may be inside the house, under the slab, or in the line from the meter to the home. A detection visit narrows it down.
Why is my water bill so high when nothing changed?
A slow leak can run for weeks before anything looks wet. Compare recent bills and check the meter with everything off. If usage stays high, book detection before the damage spreads.
A plumber already looked and could not find the leak. Can you?
Often we can. We test sections of the line to narrow the search instead of guessing. Tell us what the earlier plumber checked so we do not repeat it.
Can you find a leak between the meter and the house?
Yes. Buried supply lines are a common hidden source. A wet patch of yard or unusually green grass above the line is a typical clue. Our water line repair page covers replacement options.
Do you check rentals or small commercial buildings?
We handle multi-unit homes and small commercial properties in Sterling. Describe the building on the call. Our commercial plumbing page explains how larger sites are handled.

Where We Work In Sterling
Leak detection requests come from every Sterling neighborhood, from Sterling Park and Sugarland Run to Lowes Island. A water bill that climbs with no change in use is the most common first sign, and homes backing up to the Sugarland Run creek or sitting near the Potomac add groundwater to the list of things we rule out.
