Call us at 206.792.7495 today for dependable Seattle water leak detection. We will send an experienced plumber to find those hidden leaks and save you money.
Water leaks have a sneaky way of causing trouble long before anyone notices something is wrong. A small drip behind a wall or a slow leak under the floors can quietly soak into wood, weaken drywall, and turn a simple issue into a major repair. By the time a homeowner spots mold growth, warped flooring, or a strange spike in the water meter, the leak has usually been around for a while. It can be frustrating and, honestly, a little overwhelming when you do not know where the water is coming from or how much potential damage has already taken place.
At Gene Johnson Heating, Cooling, Plumbing & Electrical, we help Seattle homeowners and businesses track down hidden leaks and put an end to the problem quickly. We’ve been serving Western Washington for over 45 years with responsive service and a team that takes pride in solving tough plumbing issues the right way. Whether you own a home, a rental property, or a commercial building, our specialists use advanced leak detection techniques and reliable equipment to locate the problem at its source and protect your property.
Our Water Leak Detection Process for Seattle Homeowners
Water leaks can hide in some tricky places, but our trained team follows a detailed process that gives us a clear path from the first inspection to the final repair. We use tools that allow us to locate leaks without unnecessary digging or opening walls unless it is absolutely required.
- Initial assessment inside and outside the home where we gather information about the signs you have noticed, check the water meter for irregular activity, and inspect visible plumbing areas for early indicators of a leak.
- Moisture mapping using sensitive detection tools to measure dampness behind walls, under floors, or around fixtures. These tools help us pinpoint unusual moisture patterns that lead us closer to the source.
- Thermal imaging scans that allow us to see temperature changes behind surfaces, showing where water may be escaping from a water line due to cooling or heating differences. This step is especially helpful for hidden leaks.
- Acoustic leak detection using specialized listening equipment to track the sound of running water inside walls, concrete, or underground pipes. This technique helps us narrow down the exact area to investigate.
- Pressure testing of individual lines to identify which plumbing branch has failing components. We isolate sections of the system and test pressure strength to find problem areas quickly.
- Final confirmation with pinpoint locating tools that allow us to mark the exact location of the leak so repairs can be completed accurately and with minimal disruption to the house.
With this process, we eliminate guesswork and avoid unnecessary damage to your property. Our goal is to detect the leak quickly, give you clear answers, and recommend next steps that make sense for your home or business.
Once the source is identified, you will know exactly where the issue is and what needs to be addressed. We want you to feel confident in the plan before any repair work begins.
Once We’ve Detected the Leak, We Repair It!
Finding the leak is only part of the job, and we never leave clients hanging once the source has been located. Our plumbers handle everything from simple pipe repairs to replacing damaged sections of your water line. Whether the leak is tucked behind drywall, hiding under flooring, or found outside in the yard, we complete the repair with careful workmanship and long-term reliability in mind. You will know what caused the issue, what we fixed, and how to prevent similar problems in the future.
We’re Always Available for Emergency Leak Repairs!
Some leaks cannot wait, especially slab leaks or open pipe leaks that allow water to flow freely into the property. Our team provides emergency plumbing response 24 hours a day, so Seattle homeowners and businesses are not stuck watching water damage spread. If you notice sudden running water, hear a burst pipe, or find water rising where it should not be, we respond quickly with the equipment needed to stop the problem and repair it safely.
How Does Leak Detection Actually Work?
Professional leak detection relies on tools and training rather than guesswork. The process involves identifying moisture, listening for escaping water, and analyzing pressure behavior inside the plumbing system. Our team uses several techniques during an inspection.
These include:
- Moisture meters to measure dampness inside structures
- Infrared thermal imaging to highlight unusual temperature patterns
- Acoustic listening devices for underground or in-wall leaks
- Meter checks to measure unexpected water usage
- Pressure tests that isolate the leaking line
Each tool gives us a piece of the puzzle. By combining them, we locate the leak accurately and explain what is happening before starting repairs.
What Should I Do If I Suspect a Leak in My House?
If you notice early signs of a leak, it is best not to wait. Even a slow drip can cause substantial damage when left untreated. Start by checking the water meter to see if water use increases when no fixtures are running. Make a note of where you see stains, damp spots, or hear unusual noises. Then contact a professional plumber to assess the situation. We can determine whether the leak is minor or if more serious issues like slab leaks or deteriorating pipes are present. Acting early protects your property and may save money on repairs in the long run.
Are Leak Detection Services Worth the Cost?
Many homeowners are surprised by how much water leaks can impact a property. The cost of leak detection is usually far less than repairing extensive water damage later. A hidden leak can wear down floors, walls, and insulation, and sometimes create mold that affects indoor air quality. When you invest in professional leak detection, you benefit from:
- Early discovery of problems before major damage occurs
- Reduced repair costs by catching issues quickly
- Accurate locating, which avoids unnecessary demolition
- Protection of your home’s structure and personal belongings
- Peace of mind knowing the plumbing system is working correctly
Leak detection services provide strong value because they help you save money and avoid larger problems that could disrupt your home or business.

We had a FANTASTIC experience back in 2023 with Taylor Heating when our furnace decided to retire in the middle of winter. Not only were they only place out of 5 that actually answered their phone, they showed up fast, got us a quote that was very manageable, and got the work done fast. Flash forward to 2026, our water heater decided it was also ready to retire. (20 years for the furnace, and 23 for the water heater – not bad). We didn’t bother trying any other company. I sent in a request via the online form and had a phone call back and an appointment time scheduled within an hour.
Chandler was our tech on Wednesday – he is AWESOME!!! He is very personable, he answered all of our questions, and worked to help us get the best deal. He was able to replace the water heater the same day, so we didn’t have juggle a bunch of appointments – super fast and efficient. I HIGHLY RECOMMEND the Gene Johnson team to anyone looking for quality craftsmanship, manageable pricing, and top tier customer service.

Alex and Nick did a great job installing our new water heater. They worked diligently and efficiently, getting the work done in about 8 hours. They cleaned up well, you could barely tell they were here. Everything is in working order and the new system works great.

Great experience! Joseph was able to quickly fix a difficult and urgent problem. Joseph has a wealth of experience, is very professional and explained the solution step by step – exceeding our expectations. We would ask for Joseph again.

We got notice from our water utility that their system flagged a slow leak in our system. Anna called them, very helpful. We troubleshot as best we could and came up empty. We called Gene Johnson and explained what we knew and didn’t know, scheduling a technician Friday morning. Branson Carr showed up as scheduled, we went over the situation and he started a well organized trouble diagnosis. In the end, he believed that we don’t actually have a leak, but something else. We discussed it together and in the course of breaking the system to smaller units found he couldn’t totally isolate something the utility would believe was a slow leak. Eventually he he believed it was the two valves that were likely the culprit. We had been experiencing episodic low water flow in some of our fixtures, but they came back in time. We explored that with our different background and concluded the apparent slow leak observed by the utility was likely the result of a faulty main supply valve, causing pressure drop in the system, taking some time to recharge to the rated pressure supplied by the utility, mimicking a prolonged slow leak. He recommended replacing the old gate valve with a new ball valve. I asked if we could install a leak detection/shut down capability that is readily available. He did so quickly and we noticed immediate return to the home’s original functionality.
I was very impressed with the advanced features of the monitoring and shut down, even moreso when we learned of it’s remote notices, remote control and monitoring abilities.
Branson is an excellent plumber and diagostician. He worked quickly, spending time with us until he was comfortable with the intricacies of this system.
I definitely will not hesitate to recommend him to others.

Tyler was prompt and professional. There was no upselling just straightforward information. He assessed it, informed us of the water heater failure, and they proceeded to get everything installed in the same day. Great work and easy to recommend.

Noah Amini did an outstanding job. He evaluated our needs and came back 2 days later to put a backflow valve in our sewer line to prevent rats from entering our toilet. Gene Johnson will be called next time I need plumbing work done.

Kathleen Walsh
We have used Gene Johnson Plumbing for many years. We most recently had need for a clogged drain to be unplugged in an upstairs bathroom of a rental property. The appointment was prompt and Jaren was right on time. He communicated very clearly what the job would entail and the related costs. He was professional and got the drain cleared quickly with minimal disruption to our tenants. He discussed what he found in follow-up to clearing the drain and future options that would be of benefit and help to prevent further clogs. The price for his service was reasonable and we highly recommend Gene Johnson Plumbing and will continue to use them for our future plumbing needs.
