Signs of a hidden leak

Leak symptoms we track down in Princeton

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.

Unexplained high water bill

A sudden jump with no change in usage is one of the clearest signs water is escaping somewhere you can't see.

Running-water sound with everything off

Hearing water move when no fixture is on usually means a pressurized line is leaking inside a wall or slab.

Warm spot on the floor

A warm patch on the floor often means a hot-water slab leak running under the concrete.

Damp spots, stains & mildew smell

Wet drywall, ceiling stains, or a musty smell point to a leak feeding moisture behind the surface.

Low water pressure

A drop in pressure with no clear cause can mean water is leaking out before it reaches your taps.

Meter moves with no water running

If your water meter keeps spinning while everything is off, you almost certainly have a leak.

Repair or repipe?

Fix the one leak — or repipe? Here's how we decide

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 situationUsually the smart move
A single leak on otherwise sound, modern pipeSpot repair
An accessible fixture, supply, or fitting leakSpot repair
One slab leak with the rest of the system in good shapeRepair / reroute
Repeated pinhole leaks across the houseRepipe
Old, corroding galvanized or failing pipeRepipe
Leaks that keep returning after repairsRepipe

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

What causes leaks in Princeton homes

Local soil and water make some leaks far more common here — knowing the cause helps us find them faster and fix them for good.

Clay soil & slab leaks

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.

Hard water & pinhole leaks

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.

Freeze & pipe stress

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

How much does leak detection & repair cost in Princeton, TX?

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.

Leak detection & repair FAQs

Common questions, answered

How do you find a hidden leak without tearing up my house?
We use non-invasive tools — acoustic listening equipment, thermal imaging, and pressure testing — to pinpoint a leak before opening anything. That means we access only the small spot where the leak actually is, instead of guessing and cutting into walls or slab. Call 877-317-6404.
What are the signs of a slab leak?
Common slab-leak signs are a warm spot on the floor, the sound of running water with everything off, an unexplained jump in your water bill, cracking in the slab or walls, and damp or buckling flooring. If you notice these, call quickly — a slab leak only spreads. Call 877-317-6404.
Do high water bills mean I have a leak?
Often, yes. A sudden, unexplained jump in your water bill is one of the clearest signs of a hidden leak. A quick test: with all water off, check if the meter still moves. If it does, water is escaping somewhere. We can find exactly where. Call 877-317-6404.
Can you detect leaks under a concrete slab?
Yes. Slab leaks are one of the most common leaks we find in Princeton homes. Acoustic and thermal equipment locates the leak under the concrete so we can access just that spot, or reroute the line, rather than breaking up the whole floor. Call 877-317-6404.
Is a slab leak serious?
Yes. Left alone, a slab leak erodes soil under the foundation, raises your water bill, and feeds mold and structural cracking. It rarely fixes itself and usually worsens, so early detection saves both damage and money. Call 877-317-6404.
How much does leak detection and repair cost in Princeton, TX?
It depends on where the leak is, how hard it is to access, and the repair needed, so we locate it first and give upfront, written pricing. Detecting and repairing an accessible leak is the lower end; a slab leak or reroute is more. You approve the price first. Call 877-317-6404.
Should I repair the leak or repipe?
A single leak on otherwise sound pipes is usually a spot repair. But if you're getting repeated pinhole leaks, or the pipes are old and corroding, whole-house repiping is the better long-term fix. We'll show you what we find and recommend honestly. Call 877-317-6404.
How long does leak detection and repair take?
Detection itself is often done within an hour or two. An accessible repair can be same-visit; a slab leak, reroute, or in-wall repair takes longer. We give you a realistic time and an upfront price once we've located the leak. Call 877-317-6404.
Is a water leak an emergency?
Active flooding, a burst pipe, or water near electrical is an emergency — shut off your main water valve and call right away. A slow hidden leak isn't an instant flood but still causes damage daily, so it shouldn't wait either. We offer 24/7 help. Call 877-317-6404.
Will you fix the leak the same visit?
Whenever possible, yes. Many accessible leaks are detected and repaired in one visit. Slab leaks, reroutes, or in-wall repairs may need a scheduled follow-up, but we'll explain the plan and price before starting. Call 877-317-6404.
