Leak Detection. Catch the Problem Before It Catches You
Hidden leaks can cause serious damage long before you see a single drop. Our leak detection service uses advanced tools to find leaks fast — inside walls, under slabs, and underground — so you can act before a small issue turns into a big repair bill.
What Is Leak Detection?
Finding Hidden Water
Leak detection is the process of locating water leaks that aren’t visible to the naked eye. These leaks can hide behind walls, beneath concrete slabs, or deep underground — and they’re often the cause of rising water bills, mold growth, and structural damage.
The Right Choice
Why Choose USA Plumbing & Drain Cleaning for Leak Detection?
We Use the Right Equipment
Not every plumber has the tools to find a hidden leak without guessing. We invest in professional-grade detection equipment that locates leaks accurately the first time — saving you from unnecessary demo work and repeat visits.
We Don't Just Find It — We Fix It
A lot of detection services stop at the diagnosis. We don't. Once we locate the leak, our licensed plumbers can handle the repair on the spot. You get one team, one call, and a complete solution.
Honest Assessments, No Pressure
We tell you exactly what we found and what your options are. No inflated repair scopes, no scare tactics. Just a clear explanation of the problem and a fair price to fix it.
When You Might Need Leak Detection Service
Don't Wait Long
Leaks don't fix themselves. The longer one goes undetected, the more damage it does. Here are three of the most common reasons homeowners and property managers call us for leak detection.
Your Water Bill Keeps Climbing
Unexplained Usage
A slow, hidden leak can waste hundreds of gallons of water every month without you ever noticing a puddle. If your water bill is creeping up and nothing about your usage has changed, a leak is often the cause.

You're Seeing Signs of Moisture Damage
Wall and Floor Clues
Water stains on ceilings, soft spots in flooring, peeling paint, and musty odors are all signs that water is going somewhere it shouldn't. These symptoms often point to a pipe leak that's been active for longer than you'd expect.

Your Property Has Older Plumbing
Aging Pipe Risk
Older pipes — especially galvanized steel or cast iron — are far more likely to develop pinhole leaks and corrosion over time. If your plumbing hasn't been inspected in years, proactive leak detection can catch a problem before it becomes an emergency.

Our Simple Process
How Our Leak Detection Process Works
We keep things simple. From the first call to the final repair, here's what you can expect when you work with USA Plumbing & Drain Cleaning.
We Assess Your Property
We start by gathering information about your plumbing system and the symptoms you've noticed. This helps us know where to focus and which detection methods make the most sense for your property.
We Locate the Leak
Using acoustic sensors, pressure tests, and thermal imaging where needed, we trace the leak to its exact location. This process is non-invasive and designed to give you a precise answer — not a best guess.
We Repair and Confirm
Once the leak is found, we walk you through the repair options and get to work. After the fix is complete, we verify the leak is fully resolved so you can move forward with confidence.
Frequently Asked Questions
We get a lot of questions about leak detection — and we're happy to answer every one of them. Here are some of the most common ones we hear from customers.
How do I know if I have a hidden leak?
Common signs of a hidden leak include a higher-than-normal water bill, the sound of running water when nothing is on, damp or discolored walls, and musty smells in rooms with plumbing nearby.
Will leak detection damage my walls or floors?
No — our leak detection process is non-invasive. We use listening equipment and imaging technology to locate the leak before any work is done, so we only open walls or floors if a repair actually requires it.
How long does a leak detection service take?
Most leak detection appointments take between one and three hours, depending on the size of the property and where the leak is located. We work efficiently to minimize disruption to your day.
Can a small leak really cause that much damage?
Yes. Even a slow pinhole leak can cause mold growth, wood rot, and structural damage over time. Catching it early almost always means a less expensive repair.
What types of leaks can you detect?
We detect leaks in water supply lines, drain lines, slab leaks under concrete, irrigation lines, and pipes inside walls or ceilings. If water is going somewhere it shouldn’t, we can find it.
How much does leak detection cost?
The cost depends on the size of the property and the complexity of the leak. We provide a clear estimate before any work begins so there are no surprises.
Do I need to be home during the leak detection?
Yes, we do ask that an adult be present during the appointment. Access to your main water shutoff and key areas of the property helps us work faster and more accurately.
