A sudden spike in your water bill or an unexplained damp spot on your ceiling often points to a plumbing issue that you cannot clearly see. When water escapes your pipes behind walls, under floors, or deep underground, you need specialized hidden leak detection to locate the source without causing unnecessary destruction to your home. Taking immediate action is the most effective way to prevent a minor drip from turning into a major property restoration project.
At Lovett Plumbing, we bring high-level technical proficiency to residential properties across Portland and the surrounding Pacific Northwest communities. By utilizing the same rigorous standards and highly specialized thermal imaging and acoustic locating equipment trusted in large-scale commercial and multifamily environments, we can pinpoint the exact location of the leak accurately and efficiently. Our technicians rely on data, not guesswork, to find where water is escaping your plumbing system.
Our expert team quickly transitions from diagnosis to precision repair, so your property is protected from further structural damage. We focus on clear communication throughout the entire process, making sure you understand exactly what the problem is, where it is located, and how we plan to fix it.
Hidden water leaks take many forms, from a slow drip behind drywall to a cracked pipe beneath your concrete foundation. Our technicians are equipped to find them all.
When water escapes your pipes behind walls, inside ceilings, or under flooring, the damage spreads silently before you ever see a puddle. Our technicians deploy advanced acoustic listening devices, thermal imaging cameras, and moisture meters to trace the exact path of escaping water. This data-driven, non-invasive approach lets us pinpoint the failure precisely, so we only open the wall where the repair is actually needed.
One of the most challenging types of hidden leaks occurs when pipes running beneath your concrete foundation crack or corrode. These are known as slab leaks. Because the water is trapped under thick concrete, the warning signs are often subtle. You might notice a drop in water pressure, feel a warm spot on your flooring, or hear water running when all fixtures are completely shut off. Using acoustic locators and ground microphones, we can listen through the concrete to find the exact point of failure, allowing us to intervene before the slab shifts, cracks, or causes devastating foundational damage.
Ready to locate the exact source of your water issue?
Ignoring a suspected leak, or attempting to find it through trial-and-error demolition, can lead to extensive property damage. Professional water leak detection means accurate answers quickly, protecting your investment and your family.
We have refined our diagnostic approach to ensure maximum accuracy with minimal disruption to your daily life. When you call Lovett Plumbing for leak detection in Portland or the surrounding areas, here is exactly what you can expect.
Our technician arrives promptly, listens carefully to your concerns, and performs a thorough visual inspection. We look for visible signs of water damage, check your water pressure, and inspect your main water meter to confirm active flow when no fixtures are running. This step establishes the baseline severity of the leak.
We deploy advanced tools, such as acoustic listening devices, thermal imaging cameras, or moisture meters, to trace the path of the water. Thermal cameras detect temperature anomalies caused by pooling water behind drywall, while acoustic sensors amplify the sound of water escaping a pressurized pipe. This allows us to locate the issue without tearing up your home.
Once we locate the exact origin of the leak, we mark the area and clearly explain the situation to you. We believe in complete professional accountability, ensuring full transparency before any walls, ceilings, or floors are opened. You will understand the repair strategy before we make a single cut.
With your approval, we perform precision plumbing repairs to fix the damaged pipe. Whether the job requires a minor localized repair, a section replacement, or full repiping, our technicians execute the work to the highest standards. Every repair is backed by our 1-Year Warranty, ensuring the problem is solved for good.

Dan from Gladstone was prompt, courteous, and thorough in diagnosing our plumbing issues and finding a good solution. He was experienced and knowledgeable and offered good advice for maintaining our bath/shower plumbing going forward.

Brandon was a lifesaver. In just two hours, he figured out what our rental maintenance team and another contractor couldn’t. He found the leak was coming from upstairs. He didn’t stop there either. He cleaned up the mess left behind, helped reduce the active leaking, and made sure everything was handled as well as possible on our end.

Right before Christmas, we discovered a leaking water main when our water bill was more than 3x the same period last year. On short notice, Lovett was able to get Doug out to make an initial assessment, then Brian got me an estimate without delay. Foreman Steven showed up Monday morning and was able to head off potential delays by thinking creatively. He set things up nicely so that we had water running again by late Tuesday morning!

Lovett was dispatched to fix a leaky bathtub faucet in our rental home, and the service I received was top notch! Jill reached out to me quickly and was able to schedule us for the next day. Our plumber Cameron was friendly, gave us heads-up when he would be here so I could secure our furry friends, and was able to resolve the issue no problem! I definitely would recommend Lovett for your plumbing needs.

I had a kitchen sink issue. Lovett came out, and Greg was my tech. Very smart and informative. He was efficient and clean. He answered questions. And my sink was cleared up in an hour. I was so thankful for the service and reasonable price. I will use them again for any bigger projects that might come my way. I recommend this Company fully.

I hadn’t lived in my new place for ten days when a pipe broke. Dan came first thing the next morning, cut a 5×10 hole in the wall and capped off the pipe – problem solved! He also took the time to turn down the heat on my hot water heater, and explain the plumbing system to me. I wish I could give him another star.

I had a major issue with my well system and was completely without water. After calling many companies who all said they couldn’t help, I reached Ken Williams at Lovett. Ken was immediately attentive, kind, and incredibly knowledgeable. He helped me troubleshoot the problem and quickly got their equipment scheduled and out here to get the repair underway. His professionalism and genuine care made all the difference.

Tyler came out today to inspect/replace my garbage disposal and it was such a great experience! He made the interaction very personable. He also explained different things about the process along the way and I really appreciated that along with how clean he was. He wore shoe covers and completely cleaned up the underneath of my sink as well as the yuckies in the bottom of my sink. Overall, I highly recommend!!

We use specialized, non-invasive technology rather than breaking through drywall to search for the issue. This includes acoustic sensors to listen for the vibration of escaping water, thermal imaging cameras to detect temperature anomalies caused by moisture behind walls, and electronic pipe locators to trace your plumbing lines accurately.
Common indicators of a leak beneath your foundation include a sudden increase in your water bill, the sound of running water when all fixtures are turned off, unexplained warm or damp spots on your flooring, and low water pressure. If you notice these, our slab leak detection services can pinpoint the exact location under the concrete.
We offer a 24/7 emergency response for urgent situations. A severe leak can cause rapid damage, so our dispatch team prioritizes active water emergencies across Portland, Beaverton, Vancouver, and our wider PNW service area to get a technician to your home quickly.
Our goal is always minimal disruption. By using commercial-grade diagnostic equipment, we can accurately locate the hidden leak first. This means if we do need to access a pipe behind a wall or under a slab, we only open the exact area necessary for the repair, saving you from widespread demolition.
Yes. Every repair we complete is backed by professional accountability and our 1-Year Warranty. Once we fix the source of the leak, you can trust the integrity of your plumbing system moving forward.
A sudden, unexplained increase in your water bill is one of the most reliable signs of a hidden leak. You can verify it yourself by turning off every fixture and appliance that uses water, then watching your water meter for five to ten minutes. If the meter dial or digital display is still moving, water is escaping somewhere in your system. Call us to track down the source.
Shut off the main water supply to your home immediately. Your main shutoff is typically near the water meter or where the supply line enters the house. Stopping the flow limits damage while you wait for a plumber. Once the water is off, note any visible wet spots, stains, or sounds you heard, as this information helps our technician narrow down the location quickly.
Yes, in most cases. We use acoustic ground microphones and electronic listening devices to hear the specific sound of water escaping a pressurized pipe through the concrete slab. This lets us mark the precise point of failure before any concrete is touched. We only break through the slab at the exact spot where the repair is needed, not across a wide search area.
Most residential leak detection visits take one to three hours, depending on the size of the home and how many plumbing lines need to be tested. Simple in-wall leaks are often located quickly. Slab leaks or suspected underground line failures may take longer because we methodically work through the plumbing system with multiple diagnostic tools to confirm the exact source before recommending a repair.
