Not guessed
The basics
A small leak is never small for long
A leak the size of a pinhole can waste thousands of gallons a year and feed mold, rot, and foundation problems long before you ever see a drop. The hard part is not fixing a leak, it is finding it without tearing your home apart guessing. That is what professional water leak detection is for, and it is what we do best. We use the right detection equipment to locate the source precisely, so the repair is small, targeted, and done right the first time.
What we find & fix
Leak detection services
If water is going somewhere it should not, our plumbing leak detection tracks it down, wherever it is hiding, in homes, businesses, and pool lines.
Hidden Water Leaks
Drips behind walls, ceilings, and floors found and fixed before they cause real damage.
Slab Leaks
Leaks in the lines beneath your concrete slab pinpointed without jackhammering the whole floor.
Underground Water Line Leaks
Yard, main, and service line leaks located precisely so we dig only where we have to.
Pool & Spa Line Leaks
Losing water from your pool or spa? We detect leaks in pool plumbing, returns, and supply lines.
Pinhole & Pipe Leaks
Tiny corrosion leaks in copper and supply lines tracked down and repaired or repiped.
Toilet & Fixture Leaks
Silent toilet, faucet, and fixture leaks that waste water and run up your bill, found and fixed.
Commercial Leak Detection
Leak detection for restaurants, retail, rentals, and multi-unit buildings, with minimal disruption.
Leak Repair & Repipe
Once we find it, we fix it, from a single spot repair to repiping a failing section of line.
Our technology
How we pinpoint a leak
The right tools mean we find the exact spot instead of guessing, so repairs stay small and your home stays intact.
Acoustic Listening
Sensitive sonic equipment hears water escaping a pressurized pipe, even through concrete, tile, and soil.
Thermal Imaging
Infrared cameras reveal the temperature differences a hidden hot or cold water leak leaves behind a surface.
Video Pipe Camera
A waterproof camera travels inside the line so we can see cracks, breaks, and bad joints with our own eyes.
Pressure Testing
By isolating and pressurizing sections of the system, we confirm exactly which line is losing water.
Tracer Gas
A safe detector gas introduced into the line rises to the surface at the leak, marking buried leaks precisely.
Moisture Meters
Moisture and humidity meters map where dampness is spreading behind walls and under floors to narrow the source.
Catch it early
Signs you have a hidden leak
Notice any of these? It is worth a call. The sooner we find it, the smaller the repair.
Your water bill jumped
A sudden, unexplained increase usually means water is escaping somewhere you cannot see.
Running water you cannot place
Hearing water move when every tap is off is a classic sign of a hidden leak.
Warm spots on the floor
A warm patch on a slab floor can mean a hot water line is leaking underneath it.
Musty smell or mold
A persistent damp, musty odor or new mold and mildew points to moisture feeding it.
Stains, bubbling, or peeling
Water stains on ceilings or walls, or paint and wallpaper bubbling, mean water is getting behind them.
The meter keeps moving
Turn off all water and watch the meter. If it still climbs, water is leaking somewhere on your line.
If you suspect a leak
What to do right now
A few quick steps can limit the damage and help us pinpoint the problem faster.
1
Shut off the water
Turn off your main shutoff valve to stop the flow, especially with a burst pipe or a fast, visible leak.
2
Check the meter
With everything off, watch your water meter. If it keeps moving, water is still escaping somewhere on your line.
3
Protect your space
Move valuables away from wet areas and soak up standing water to limit damage and slow mold growth.
4

Smart leak protection
Stop the next leak automatically
Detection finds today’s leak. A smart water monitor helps you catch the next one the moment it starts. These devices mount on your main line and learn your home’s normal water use, then alert your phone the instant they sense an abnormal flow, a drip, or a drop in pressure. Paired with an automatic shut off valve, the system can close your water on its own, stopping a burst pipe from flooding your home even while you are away. We install and set up smart monitors and shut off valves, and integrate them with the plumbing you already have.
- Real time leak and flow alerts sent straight to your phone
- Automatic whole home shut off the moment a leak is detected
- Freeze, pressure, and unusual usage monitoring
Peace of mind
Ask about a smart water monitor
Especially smart if you travel, own a rental, or have a finished basement. We will recommend the right device and install it clean.

Highly recommend John Brown from Clarksburg Plumbing LLC! Yesterday John flushed and descaled our tankless water heater. We've gotten used to waiting and waiting for service people. That's not the case with John. He arrived pleasantly early for both the initial visit (for a no-cost estimate) and for the actual service call. He was personable, knowledgeable, and very patient with our many questions. He really helped us understand the ins and outs of this new-to-us technology of tankless water heaters. We're already recommending him to our neighbors!

I had Clarksburg Plumbing come out for a minor home plumbing repair. Seth and Maddie were on time, friendly, and professional. They provided a free estimate, and I went ahead with the repair. The repairs took just under 2 hours and I was completely satisfied with the service. I will definitely use Clarksburg Plumbing again in the future. Thanks, Seth and Maddie!

We had a very good experience with Clarksburg this year. A new fresh water pipe from the street and cleaning the waste pipe. From Brady in the office to John Brown and his team on site (Franklin and Chris) everything went smoothly, successfully, and on time. Would highly recomnend!

I recently used Clarksburg Plumbing for a condo repair of my main water turnoff valve and my outside hose bib. It required coordination with DC Water and the condo, and Clarksburg was extremely helpful, professional, and patient in the process. They came out a few times to evaluate and troubleshoot the issues, and then ultimately performed/made the repairs. Garrett and John Brown were the first to help, both very kind, knowledgable and highly skilled, and then Pablo (along with apprentice Tevon) made the final repairs. Not only did they do a great job, explaining everything to me in the process and checking after the water was restored to the condo, they also helped out one of the other owners that was having a sudden, luckily minor issue, as well. It’s a relief to know that I finally have a plumbing company that I can rely on for any future issues.

We had a fire at our house 3-Jul-2025. Our contractor used Clarksburg Plumbing for all of our plumbing needs as we rebuilt our house. Pablo was with us from the beginning until all work on the house was completed a year later. Pablo was the lead plumber from Clarksburg Plumbing. He worked on the plumbing rough-in in December through February this past winter in bitter cold through the end of July 2026 when work was finally completed. Pablo quietly does his work. It’s clear that he is very skilled but he is not arrogant in any way. Rather, he is very engaging, takes suggestions under consideration and employs them as warranted, and is always kind even when I interrupt his work. Pablo represents Clarksburg Plumbing very well. It was my pleasure working with Pablo.

Properly identified the source of my leak after multiple other plumbers/companies couldn’t figure it out. Were thorough in explaining what they were doing, how they arrived to their determination, and gave advice on how to proceed with next steps that were outside their scope of operations. Thanks Pablo and Tevon

We had a severe blockage in our kitchen sink drain, causing water to back up into both the sink and the dishwasher. Seth and Brady arrived on time, quickly identified the issue, and did an excellent job clearing the kitchen drain. They also fixed the dishwasher drain line, which is now working perfectly. They were professional, efficient, and courteous throughout the process. I highly recommend them to anyone needing plumbing services.

Good questions
Leak detection FAQ
What homeowners ask us most about finding and fixing leaks.
How do you find a leak without tearing up my house?
We use non invasive equipment first: acoustic listening devices, thermal imaging, video pipe cameras, pressure testing, and moisture meters. Together they let us pinpoint the leak to a small area, so when we do open a wall or floor, it is one targeted spot instead of guesswork.
What are the signs of a hidden water leak?
The most common are a sudden jump in your water bill, the sound of running water when everything is off, warm spots on a slab floor, musty smells or mold, low water pressure, stains or peeling paint, and a water meter that keeps moving after you shut everything off.
My water bill spiked. Could it be a leak?
Very likely. A jump with no change in your habits usually means water is escaping somewhere. A quick test: turn off all water, then check your meter. If it is still moving, you have a leak, and we can find it.
What is a slab leak?
A slab leak is a leak in a water line running beneath your concrete foundation. Signs include warm spots on the floor, the sound of water under the slab, unexplained high bills, or cracks. We locate them precisely so the repair stays as small as possible.
Can you find a leak in my underground water line?
Yes. Soggy spots in the yard, a drop in pressure, or a spinning meter often point to a buried service line leak. Using acoustic and tracer methods we locate it without digging up the whole lawn, then repair or replace just the failed section.
Do you install smart leak detectors and automatic shut off valves?
We do. A smart water monitor learns your normal usage and alerts your phone to abnormal flow, and an automatic shut off valve can close your water on its own when it senses a leak. It is excellent protection, especially if you travel or have a finished basement.
Do you repair the leak too, or only find it?
Both. We are a full plumbing company, so once we pinpoint the source we make the repair or replace the failing line, all with one team. No need to find a second contractor.
What areas do you serve?
We serve Clarksburg, Germantown, Gaithersburg, Rockville, Damascus, Potomac, North Bethesda, and the surrounding Montgomery and Frederick County area.
