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.

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

Call us

Reach out and we will pinpoint the leak with our detection equipment and repair it, with as little cutting or digging as possible.

Spotting one of these signs?

The sooner we pinpoint the leak, the smaller the repair. Let’s take a look today.

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.

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 needed a water valve installed for my new fridge and a new faucet installed in upstairs bathroom. Seth was amazing. He came out and really listened to me and my concerns. We even called the company that was going to deliver my new fridge so he would have a better understanding of what he needed to do his job. It made me feel at ease with the whole process. He is even coming back later in the week to install new fridge once it’s delivered. I will absolutely call them again.

We had a pinhole leak suddenly appear in our outdoor hose bib, and Clarksburg Plumbing was able to provide next-day service, which we really appreciated. Our technician, John Brown, arrived right on time after giving us a 30-minute courtesy call. John quickly diagnosed the problem, explained everything clearly, and provided an accurate assessment of what needed to be done. He completed the repair in under two hours, and the quality of his work was excellent. Before leaving, he even took the time to share some helpful tips on how to prevent similar issues in the future. John was friendly, professional, knowledgeable, and efficient from start to finish. We couldn’t have asked for a better service experience. I highly recommend Clarksburg Plumbing and especially John Brown for anyone needing reliable, high-quality plumbing work.

Seth was absolutely amazing! He was very courteous and knowledgeable about his profession. He arrived on time and worked the entire time. He kept me in the loop the entire way as to what he was doing. He diagnosed two leaks within our toilet system and readily fixed them. Clarksburg Plumbing should be honored to have such an amazing employee as him.

Good questions

Leak detection FAQ

What homeowners ask us most about finding and fixing leaks.

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.

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.

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.

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.

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.

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.

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.

We serve Clarksburg, Germantown, Gaithersburg, Rockville, Damascus, Potomac, North Bethesda, and the surrounding Montgomery and Frederick County area.
