Fast Leak Detection That Prevents Damage
We find hidden water leaks quickly to protect your home, lower waste, and stop costly repairs.
Service Details
At JAC's Plumbing, we help homeowners and light commercial property owners in Denver find hidden leaks before they turn into expensive damage. Leak detection is one of the most important plumbing services we provide because many water problems start out of sight. A small leak behind a wall, under a slab, in a ceiling, or along a water line can waste water for weeks before you notice it. By the time stains, warped flooring, mold, or a high water bill show up, the damage may already be growing. Our job is to locate the source quickly, explain what we find clearly, and help you take the next step with confidence.
Hidden plumbing leaks can come from many places. We commonly find leaks in water supply lines, drain pipes, pipe fittings, shut-off valves, toilets, faucets, hose bibs, water heater connections, and main water lines. In some properties, the problem shows up as damp drywall, bubbling paint, musty smells, warm spots on the floor, low water pressure, or the sound of running water when everything is turned off. In other cases, the only warning sign is a sudden spike in the water bill. If you have noticed any of these issues, it is smart to schedule leak detection right away.
Our leak detection service is designed to be thorough and practical. We start by listening to what you have noticed around the property. Then we inspect the plumbing system and the areas where the issue appears to be showing up. We work to narrow down the location of the leak with as little disruption as possible. The goal is simple: find the problem fast, prevent more water loss, and reduce unnecessary damage to walls, floors, cabinets, and foundations.
When we perform leak detection, we are looking for both obvious and hard-to-find plumbing issues. That includes active leaks, slow pinhole leaks, pressure-related leaks, worn connections, aging pipes, and hidden moisture problems that may point back to a plumbing failure. In older homes around Denver, plumbing materials, shifting conditions, and normal wear over time can all increase the chance of a hidden leak. Catching the issue early can help you avoid larger repairs later.
One of the biggest benefits of professional leak detection is that it helps prevent guesswork. Instead of cutting into multiple walls or replacing parts that are not actually causing the problem, we focus on locating the source and giving you a clear explanation of what is happening. That saves time, protects your property, and helps you make a better repair decision. If a leak is connected to another plumbing issue, such as a failing water line, drain problem, or water heater connection, we can explain those findings too.
Because we are a small, hands-on plumbing company, our customers get direct communication and straightforward service. JAC's Plumbing has been serving the Denver metro area since 2012, and we bring 13 years of hands-on experience to every job. We are known for high-quality communication, honest recommendations, and upfront flat-rate pricing. If we uncover a leak, we will walk you through the condition of the plumbing, what repair options make sense, and what to expect moving forward.
Leak detection is often the first step in stopping larger property damage. A hidden leak can lead to stained ceilings, damaged insulation, weakened drywall, cabinet damage, flooring problems, mold growth, and even structural concerns if it continues long enough. Water waste is another major issue. Even a small plumbing leak can add up fast on your monthly utility bill. Finding and addressing the source early can protect both your home and your budget.
We also understand that some leaks cannot wait. If you have a sudden loss of pressure, signs of major water intrusion, or an urgent plumbing issue, contact us right away. We offer emergency plumbing service when scheduling allows, and we will do our best to help you act quickly before the damage gets worse.
In many cases, leak detection is tied to other plumbing services. If the problem is related to a water heater, main water line, drain issue, or sewer and water line condition, we have the experience to help with that next step as well. Our team handles water heaters, drain cleaning, and sewer and water line replacements, so you are not left trying to coordinate multiple contractors just to solve one plumbing problem.
If you are dealing with unexplained water, rising utility bills, damp spots, musty odors, or signs of a hidden pipe leak, JAC's Plumbing is ready to help. We serve residential and light commercial customers across the Denver metro area with dependable service and clear answers. Call us at (720) 742-5227 to schedule leak detection today. If you prefer, you can also reach out through our website form to request service. The sooner we find the leak, the sooner you can protect your property and stop the waste.
Our Leak Detection Process
At JAC's Plumbing, we use a clear, proven process to find hidden leaks fast, explain what we find in plain language, and help you stop water damage with confidence.
Call, Triage & Smart Scheduling
When you call JAC's Plumbing, we ask the right questions about water spots, pressure loss, high bills, or slab leak signs to narrow down the issue. We give upfront, flat-rate pricing when possible and schedule fast service in Denver, including emergency help when availability allows.
Non-Invasive Leak Testing
On site, we inspect fixtures, supply lines, drain lines, and exposed piping, then use professional leak detection methods to pinpoint hidden water loss with minimal disruption. If needed, we can pair the visit with camera inspection insights to check related drain or sewer concerns and rule out bigger plumbing issues.
Clear Findings & Repair Plan
Once we locate the leak, we show you what we found, explain the cause, and outline the best next step, whether that is pipe repair, fixture replacement, or line work. Before we leave, we answer your questions, review timing, and make it easy to book the repair so you can protect your home from further damage.

UPDATE - 4/9/26 I’ve now had Jeff and one of his employees, Anthony, back at my house several times since my original review, and they continue to go above and beyond every single time. They’ve handled everything from re-plumbing an entire bathroom remodel, to trimming out a Delta shower system, repairing a main stack drain, and even catching mold that the mold mitigation company completely missed. That alone says a lot about their attention to detail and level of care. Jeff and Anthony are both incredibly knowledgeable, thorough, and easy to work with. They take the time to explain what’s going on, do the job right, and make sure everything is solid before they leave. At this point, I don’t even consider calling anyone else. Jeff and his team are my go-to for anything plumbing-related, and I recommend them without hesitation."

"Look no further. You found the best plumber in Broomfield. Why do I think that? Because I called Jeff to replace a water supply valve for my refrigerator, but he said I didn’t need to. Instead, he suggested I get a wireless water leak detector system and to call him when I really do need the valve replaced. He easily could have told me that I did needed to replace the valve, done the work and made some money. But, he didn’t. He was honest!"
"I hired JACs Plumbing on a recommendation from another plumber to remove all my original galvanized piping/drain lines. Jeff and Abraham were professional and got a difficult job done. They communicate well, kept me updated on scheduling, educated me on how it all worked. They are professionals. Hire them!"
"Jeff came over to check our hot water heater and gave us a lot of helpful information."
"Run, don’t walk to use JAC’s Plumbing. Best in the Colorado front range!"
"This was the second time I have used JAC's. The first was last January when I noticed a leak on the sewer pipe in the utility room. I called and Jeff came out and checked. It was the worst you could imagine. Jeff had to replace the sewer stack and related plumbing. He replace the pipes from the bathroom upstairs, the plumbing to the kitchen sink and the bathroom sink. He was here for hours, polite and informative the entire time. He did a great and professional job and was fair in pricing. I just had him back to finish the supply pipes to bathroom sink. I added on replacing the outdoor faucet. Jeff suggested we replace the faucet for the water main due to corrosion, we agreed. The pipes are 62 years old. We are so glad we did. Again Jeff was polite, professional and we believe very fair. Would we recommend or use JAC's again? In a heartbeat, very pleased."
