Post-Tension Slab Leak Detection in Longmont
Many newer homes are built on post-tension slabs that use steel cables under high tension. Cutting into one without care is dangerous and can damage the foundation. We locate the cables with scanning equipment before any repair access is opened. This lets us repair the leak without risk or recommend a reroute that avoids the slab entirely.

Emergency Slab Leak Detection in Longmont
A sudden drop in water pressure, visible dampness or the sound of running water can indicate an emergency slab leak. GFR Plumbing offers emergency detection services in Longmont to address urgent situations quickly. We prioritize rapid response to limit water damage and prevent further structural compromise to your property.
Thermal Imaging for Slab Leaks in Longmont, CO
Thermal imaging cameras allow us to see temperature differences on surfaces, which can indicate a hidden water leak. As water escapes a hot water line, it creates a distinct thermal signature on the concrete slab. This technique is particularly useful for hot water line leaks and helps us narrow down the search area quickly without any physical disruption to your property in Longmont.
Acoustic Slab Leak Detection in Longmont
Our technicians rely on highly sensitive acoustic listening devices to pinpoint the exact location of a leak under your slab. This method involves listening for the subtle sound of escaping water, even through concrete. It's particularly effective for pressurized water lines, allowing us to find leaks without unnecessary excavation and minimizing disruption to your Longmont home.
Repiping After Multiple Slab Leaks in Longmont, CO
If your home has had two or more slab leaks, the remaining pipe is likely corroded too. Repiping replaces all supply lines with new PEX or copper run through the walls and attic. It is a bigger project, but it ends the cycle of repeat slab leaks. We can usually complete a full repipe in two to four days.
Commercial Slab Leak Detection in Longmont, CO
Commercial properties in Longmont, CO also face the risk of slab leaks, which can disrupt business operations and lead to serious structural damage. GFR Plumbing offers dedicated detection services for businesses, using the same technology to minimize downtime. We work quickly to locate leaks in offices, retail spaces and other commercial buildings.
Electronic Acoustic Leak Detection in Longmont
Our team uses electronic listening devices to pinpoint the precise location of a slab leak. These highly sensitive microphones can detect the faint sound of water escaping from a pressurized pipe under your foundation. This non-invasive method helps us avoid unnecessary concrete breaking, saving you time and money on repairs. It's particularly effective for copper and PEX lines commonly found in Longmont homes.

Slab Leak Repair Through Direct Access in Longmont, CO
When a single leak is found on otherwise healthy pipe, direct access can be the most affordable repair. We cut a small opening in the floor at the marked spot, repair the pipe and pressure test it. Then we patch the concrete and leave the area ready for flooring. Accurate detection keeps that opening as small as possible.

Frequently Asked Questions About Slab Leak Detection in Longmont
The cost of slab leak detection in Longmont, CO usually ranges from $250 to $700, depending on the complexity of the leak and the time required for detection. This cost covers the professional equipment and expertise needed to accurately locate the leak, which is crucial before any repair work can begin.
Direct repair works well for a single leak on otherwise healthy pipe in an accessible spot. Rerouting is often better under tile or hardwood and avoids future leaks on that line. We help you weigh both.
While the detection process itself typically doesn't require a permit, any subsequent repair work involving the excavation of the slab or significant plumbing alterations will likely require a plumbing permit from the local building department. GFR Plumbing takes care of all necessary permits for repair work.
We stand by the accuracy of our slab leak detection services. While detection itself is a diagnostic service, we make sure our findings are precise. Any subsequent repairs performed by GFR Plumbing come with our standard labor and parts warranties, which will be clearly outlined for you.
GFR Plumbing uses industry-leading brands for our slab leak detection equipment, including but not limited to LeakTronics, FLIR thermal cameras and specialized acoustic sensors. These tools are chosen for their accuracy and reliability in various leak detection scenarios, delivering the best results for your home.
Some homeowner's insurance policies may cover the cost of accessing and repairing the slab leak, particularly if the leak was sudden and accidental. However, coverage often varies, and damage caused by long-term neglect might not be covered. We recommend checking your specific policy details or contacting your insurance provider for clarification.
Common signs of a slab leak include surprisingly high water bills, warm spots on your floor, the sound of running water when no fixtures are in use, visible cracks in the foundation, damp or wet spots on carpets or flooring and a sudden drop in water pressure. Musty odors can also indicate moisture buildup.
Once the slab leak is precisely detected, our technician will provide you with a detailed report and discuss the best repair options. These options may include trenchless repair, re-routing the affected pipe or traditional slab excavation and repair. We will then provide a transparent estimate for the repair work.
