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.

Tevon, Noah, Markell, and Morrow were sent by Clarksburg Plumbing LLC to repair an outside broken waterline They arrived at the appointed hour and completed the work in about 3 hours. I was very impressed with them and I would like to recommend all four of these very professional and friendly technicians. Clarksburg Plumbing is a fantastic organization; the office staff, Katie and Charlotte, who helped me are the best.

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.

GREAT service and expertise! John and Maddie just installed a water filtration system to our home. The process took one day to install and then they came back from the 48 hour install period to ensure everything was working well. John was familiar and knowledgeable about the water system we bought. Maddie and John kept our space clean, clearly explained how to ensure longevity for our system to last, and the difference it will make in our home. We appreciate their hard work and professionalism. This is our second time using Clarksburg plumbing. We would highly recommend their company to our family and friends.

Franklin and his crew showed up promptly and communicated great with us to help limit disruption with the tenants at 4 of our building. Unfortunately for us a second water main leak occurred the day before. But luckily for us they were able to stay on site another 2 days and knock the second one out, even staying till 8pm to find the line and get it repaired. These will be the guys I request for our next time needs

Seth provided an estimate on 8/25 for upgrading my basement sump pump to a dual system. He explained the setup clearly and promptly reordered the exact Wi-Fi-capable model I requested before installation. Seth and Maddie returned on 8/28 and did a fantastic job. The system works great, and their professionalism was top-notch. Highly recommended!

Katie and the Clarksburg Plumbing team were phenomenal. Katie came highly recommended, and it could not have been a better choice. During an emergency plumbing issue at one of the buildings we service, her team came right out and made it happen. It was a complicated situation, but they handled it from start to finish with great responsiveness, professionalism, and patience throughout the entire process. We greatly appreciate their help and highly recommend them.

The plumber from Clarksburg Plumbing who worked on my broken gas hot water heater was John Brown. John is an amazing plumber. He is extremely energetic, very efficient, has amazing knowledge about plumbing, and is very honest. He is also very friendly, considerate, and took the time to answer all my questions. He diagnosed the problem quickly (which was a defective burner assembly). Then when I showed him the manufacturer's warranty, he took the initiative to immediately call the manufacturer and order all the necessary parts (which were free under the warranty). When the parts were delivered, he made sure to show up the next day and install the parts. As we talked throughout his time in the house, I could see that he has very deep knowledge of plumbing, which gives me confidence that his work is top quality. I also had a problem with very high water pressure in the house. The pressure regulator had to be replaced. John, working with Maddie, did a great job in fixing that as well. After the work, everything was cleaned up completely.

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.
