Finding Hidden Leaks, Once and For All

You know the signs of a leak: rising water bills, wet spots, musty odors, unexplained moisture, or the sound of running water when nothing’s turned on.

What’s not as obvious, though, is where the leak is actually coming from. That’s because many leaks are hidden behind walls, beneath floors, or underground, quietly causing damage long before they’re visible.

GEM Plumbing & Heating Services, LLC, provides professional leak detection services using advanced methods to locate the problem accurately and efficiently. Our experienced plumbing technicians find the source of the leak with minimal disruption, helping you stop the damage, save water, and restore peace of mind.

Contact us today for service in Rhode Island and Massachusetts. Schedule professional leak detection with GEM today to find the source quickly and protect your home from hidden water damage.

Leaving No Stone Unturned to Find Your Hidden Leak

Leaks are great at hiding, and they usually stay hidden until they cause serious damage.

At GEM, we’re here to help you find your leak before extensive problems develop. We use the top systems and equipment to locate your leak with expert precision, no matter where it’s hiding.

Leaks inside walls or ceilings often go unnoticed until damage appears. Specialized detection tools help locate moisture and pinpoint the source without unnecessary demolition.

Slab and subfloor leaks can cause serious structural damage if left untreated. Careful inspection beneath flooring and concrete surfaces helps uncover hidden leaks early.

Joints, fittings, and aging pipes are common sources of pipe leaks. A thorough inspection of supply and drain lines helps identify weak points and failing connections.

Sinks, toilets, showers, tubs, and appliances are frequent leak locations. Fixtures and surrounding areas are checked closely to find places where moisture may be building up.

Leaks around water heaters, laundry rooms, and mechanical spaces can spread quickly. Valves, connections, and nearby piping are inspected for early signs of trouble.

Exterior water lines and underground pipes can leak without visible signs. Advanced detection methods help locate hidden leaks and prevent water waste or property damage.

Review for David Salvatore from Gem Plumbing and Heating

I recently had the pleasure of working with David Salvatore from Gem Plumbing and Heating on March 31, 2026, when he performed maintenance on my air conditioning systems. The service he provided was exceptional and very thorough. David demonstrated great professionalism, expertise, and efficiency throughout the process.

My overall experience with David was great, and I would highly recommend his services to anyone in need of HVAC maintenance and repairs. Thank you, David, for your excellent work!

Nicole was incredibly knowledgeable, honest, and efficient! I was so thankful that she was able to get here quickly on a Saturday when we had an unknown alarm blaring in our basement. It turned out to be something in our AC unit that was luckily replaceable same day.

Aaron came for a 2nd successful visit. This time to figure out the cause of low/no water pressure in some of our H&C setups for 5 bathroom sinks. He left with 3 sinks H&C flowing freely & demonstrated the need for 2 new faucet installations so Hot H2O could be restored to the remaining sinks. Much appreciated as others had immediately started talking about replacing pipes without investigating less complicated solutions. As before, Aaron was a professional pleasure to have in our home & pricing will be the only holdup for us to continue with the faucet installations. Due to him, I have high hopes for the GEM electrician arriving next week & the HVAC maintenance later this month.

Very professional service. They came the same day and solved the problem quickly and completely. I would definitely use Gem again if I needed plumbing work.
Mark Sutherland
I called GEM because I wanted my ductless AC’s checked to see if they needed any service. Christopher Cennamo came and examined both units and said they were functioning properly but needed a cleaning to remove mold and dirt. The large unit is at the top of a stairwell so access requires a tall ladder. Christopher made the appointment to return to do the cleaning and also to determine why the larger unit was tilting off the wall. He returned today and determined that the larger unit’s mounting bracket was only attached to drywall and not a wooden stud. He and Brody Lott secured the mounting bracket to a stud, ensuring the unit is now securely on the wall. A thorough cleaning of both units was completed including removal of a mouse nest. Christopher told me how to use steel wool in the outside pipe cover to prevent mice from entering which I promptly did. Christopher Cennamo was very professional, thorough, knowledgeable and explained everything. The cleaning was expensive but worth it. Plus he didn’t charge extra to repair the faulty mounting issue because GEM had done the initial install and not done it properly. I highly recommend Christopher Cennamo for any of your heating and cooling jobs.

Signs You May Have a Hidden Water Leak

Some signs of leaks are obvious, and others demand a bit more attention to uncover.

Not sure if you’re dealing with a leak? Look out for some of the most common signs, like:

If your water usage hasn’t changed but your bill has gone up, a hidden leak could be the cause. Even small leaks can waste a surprising amount of water over time.

Damp areas on walls, ceilings, or floors are often signs of a leak behind the surface. Discoloration, bubbling paint, or warped materials should never be ignored.

Persistent musty smells can indicate moisture buildup from a hidden leak. Over time, this trapped moisture can lead to mold growth and indoor air quality concerns.

Hearing water running when no fixtures are in use is a common warning sign. This often points to a leak in a pipe, wall, or underground line.

A sudden or gradual drop in water pressure may signal a leak in your plumbing system. Leaks can reduce the amount of water supply reaching your fixtures and appliances.

Leak Detection FAQs

How does professional leak detection work?

Professional leak detection uses specialized tools and techniques to locate hidden leaks without unnecessary damage to walls or flooring. Technicians may use acoustic listening devices, moisture meters, thermal imaging, and pressure testing to pinpoint the exact source of the leak. Once the leak is located, the technician can recommend the best repair approach.

Do I need leak detection if I don’t see visible water damage?

Yes, leaks can exist long before visible damage appears. Signs such as rising water bills, musty odors, damp areas, or the sound of running water may indicate a hidden leak. Professional leak detection helps locate the problem early so it can be repaired before more serious damage occurs.

Will leak detection require cutting into walls or floors?

Not usually. Professional leak detection uses non-invasive tools to locate the source of a leak without unnecessary cutting into walls or floors. If a repair is needed, only the small area required to access the pipe is opened.

How quickly should I schedule leak detection?

Leak detection should be scheduled as soon as you notice warning signs like rising water bills, musty odors, or unexplained moisture. Early detection helps prevent further damage and wasted water, helping prevent water damage, mold growth, and higher repair costs.

Can leak detection help lower water bills?

Yes, leak detection can help lower water bills by identifying hidden leaks that may be wasting water without your knowledge. Even small leaks can add up to significant water loss over time. Finding and repairing the source helps restore efficient water use and reduce unnecessary costs.
