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.

A terrific, reassuring experience getting me through a broken sewer line emergency which required digging up and replacing 20 ft of cracked, aging sewer line that had a belly. Everyone I worked with at Clarksburg was professional, competent, and efficient. The price was reasonable as well . Special shout out to my excavation crew: Noah, Markell, and Deybis headed by Jason. Thanks to Garrett and Cris who did my initial emergency intervention, snaking and diagnosis, Teyvon, John and Brady who helped with the hydrojetting, camera, and advice on how to prevent recurrence before pipe replacement. On a previous occasion, I had a great experience with Tyler who checked for a toilet leak and caulked. Finally, I greatly appreciated the comforting attention of the excellent reception staff Charlotte and Katie. Much appreciated Clarksburg Plumbing!

I had an absolutely wonderful experience with Clarksburg Plumbing LLC, and especially with Seth. From the moment he arrived, he was professional, respectful, knowledgeable, and quite frankly, a breath of fresh air. I was extremely nervous about the situation because my leak was below the main water shutoff valves, and the water had to be turned off at the street. Seth immediately put me at ease and assured me that everything was going to be okay. Rather than just putting together a temporary solution, he wanted to make sure he ordered the exact parts needed to do the job properly. Seth told me he expected to have the correct part and be able to return on Wednesday to complete the repair. On Tuesday afternoon, the office called to let me know the part had arrived and confirmed that Seth would be back Wednesday morning between 8:00 and noon. Seth was at my door at 8:10 AM! I was genuinely impressed. He completed the repair carefully, explained everything he was doing, and was extremely conscientious about properly turning the water back on, opening the faucets in the house, and making sure everything was working exactly as it should. What impressed me most, though, was Seth himself. He has a wonderfully calm, professional demeanor that made a very stressful situation so much easier for me. I sincerely appreciate the care he took with my home and the respect he showed me throughout the entire process. Clarksburg Plumbing is very fortunate to have someone like Seth representing their company. I would absolutely recommend them and Seth!!

I had a great experience with Tyler when he came out to replace our toilet flushing system. From start to finish, Tyler was incredibly courteous, professional, and knowledgeable. He walked me through what needed to be fixed, answered all my questions patiently, and completed the job efficiently. It’s rare to find such high-quality service and attention to detail. Everything is working perfectly now, and he left the work area completely clean. I highly recommend Tyler for any plumbing needs!

Absolute best plumbers I have ever used. Needed them a few times recently and each time they were so professional, kind and resolved each problem the first time around. This last issue took them several hours to fix. They explained everything along the way and gave a very fair price for a lot of work. They also work very cleanly! I will never use another plumber! I wanted to add a new review but I could not so I am editing my previous one. I had to use Clarksburg Plumbing again today and like last time, they were exceptional. I was fortunate enough to have John and Madeleine as my service technicians. I will always request them going forward. They are kind, professional and knowledgeable! I am sure the company knows how fortunate they are to have them as part of their team!

We thank Clarksburg Plumbing again for superior, high quality and friendly service! ----- Clarksburg Plumbing visited us last week to repair an external spigot that had been leaking. The work involved creating a little inside access panel. Within and without, a nice, neat job by Charlie and his understudy apprentice, Chris. Problem solved and happy campers here! ----- UPDATE: Plumber John Brown presented himself on time and got right to work replacing my Mom's ancient leaky kitchen faucet with a new store-bought one that I provided. During the process, Mr. Brown detected and showed me two other problem areas contributing to the water leaks: a cracked drain pipe and then rusted threads on the sink trap. He efficiently and expertly repaired all three elements to our full satisfaction. Plus, John is a super nice guy, completely honest and classy enough to laugh at all my corny jokes! The next time you need any plumbing work in your home or business, I strongly endorse John Brown and anyone on the Clarksburg Plumbing team! UPDATE 2: John and his understudy Maddie visited, and quickly solved the problem of a pinhole leak in copper tubing leading from our hot water heater. He advised us on other plumbing needs, for which we have scheduled and will otherwise follow-up. Thank you Clarksburg Plumbing for your top quality people - John Brown in particular - and performance.

Thank you to Seth, who came on Wednesday and fixed one of our two toilets and fixed our primary bedroom shower. And thank you to Charlie, who came today and replaced our other toilet and replaced our garbage disposal. You are both lifesavers! Our weekend (and going forward) will be MUCH nicer now that we can use our bathrooms (and garbage disposal) again. Highly recommend Clarksburg Plumbing.

Excellent service today from John Brown and Madeleine S. They were very kind and took time to explain the issue with my dishwasher. I really appreciate their professionalism and efficiency. I would definitely consider using this company again based on my service today!
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.
