Signs of a hidden leak
Hidden leaks waste water and damage your home long before you see a puddle. These are the signs worth a call before the damage grows.
A sudden jump with no change in usage is one of the clearest signs water is escaping somewhere you can't see.
Hearing water move when no fixture is on usually means a pressurized line is leaking inside a wall or slab.
A warm patch on the floor often means a hot-water slab leak running under the concrete.
Wet drywall, ceiling stains, or a musty smell point to a leak feeding moisture behind the surface.
A drop in pressure with no clear cause can mean water is leaking out before it reaches your taps.
If your water meter keeps spinning while everything is off, you almost certainly have a leak.

How a leak visit works
Tell us the signs — high bill, warm floor, damp wall — at 877-317-6404 and we'll schedule a visit.
We use acoustic, thermal, and pressure tools to find the exact leak before opening anything.
We confirm the source and location, then give you an upfront written price to approve.
We fix it with minimal damage and confirm the leak is gone and pressure holds.
An active flooding leak gets a fast, 24/7 response. Hidden-leak detection is scheduled so we can locate it accurately — and we give you a realistic window when you call rather than a promise we can't keep.

We locate the leak before cutting, so we open only the spot that needs it.
Less demolition, less mess, and a smaller bill to put your home back together.
You approve a written price after we locate the leak — no surprises.
Burst pipes and flooding leaks get priority before they ruin floors and walls.
We stand behind the repair and confirm the leak is truly gone.
Repair or repipe?
One leak doesn't always mean new pipes. We'd rather do a spot repair when that's the right call. Here's the honest rule of thumb:
| Your situation | Usually the smart move |
|---|---|
| A single leak on otherwise sound, modern pipe | Spot repair |
| An accessible fixture, supply, or fitting leak | Spot repair |
| One slab leak with the rest of the system in good shape | Repair / reroute |
| Repeated pinhole leaks across the house | Repipe |
| Old, corroding galvanized or failing pipe | Repipe |
| Leaks that keep returning after repairs | Repipe |
If repeated leaks or aging pipes point to repiping, we'll show you why and walk through our whole house repiping options. Not sure which you need? We'll find the leak and tell you straight. Call 877-317-6404.
Why leaks happen here
Local soil and water make some leaks far more common here — knowing the cause helps us find them faster and fix them for good.
Princeton's expansive Blackland clay swells and shrinks with wet-dry cycles, shifting the foundation and stressing the pipes beneath the slab. That movement is a leading cause of the slab leaks we detect here.
NTMWD-supplied hard water and mineral buildup wear pipes from the inside, leading to pinhole leaks — especially in older copper and galvanized lines. Repeated pinholes often signal it's time to repipe.
Hard North Texas freezes can crack pipes and pop fittings, sometimes leaving a slow hidden leak that only shows up later as a high bill or damp spot. We trace those back to the source.
Transparent pricing
There's no flat price — it depends on the leak, so we locate it first and give you an upfront written price before any repair. Detecting and fixing an accessible leak is the lower end; a slab leak or reroute is more. What affects the cost:
You approve a written price before we repair — no surprises, and no paying to dig blind. Call 877-317-6404 for detection and a clear estimate.
