Thermal Imaging for Slab Leaks in Auburn, WA
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 clear 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 Auburn.
Post-Tension Slab Leak Detection in Auburn
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 safely or recommend a reroute that avoids the slab entirely.
Repiping After Multiple Slab Leaks in Auburn, WA
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 recurring slab leaks. We can usually complete a full repipe in two to four days.
Non-Invasive Leak Detection in Auburn, WA
Our primary goal is to locate your slab leak with the least amount of disruption possible. We favor non-invasive techniques like acoustic and thermal imaging before considering any intrusive methods. This approach saves your home in Auburn, WA from unnecessary damage, preserves your landscaping and reduces the overall cost and time of the repair process.
Slab Leak Repair Through Direct Access in Auburn, WA
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.
Hot Water Slab Leak Detection in Auburn
Hot water lines leak under slabs more often than cold lines because heat speeds up corrosion and causes expansion and contraction. Signs include warm spots on the floor, a water heater that runs constantly and higher gas or electric bills. Thermal imaging shows the heat pattern spreading through tile or concrete. We confirm with a pressure test and acoustic listening before flagging the spot.

Emergency Slab Leak Detection in Auburn
A sudden drop in water pressure, visible dampness or the sound of running water can indicate an emergency slab leak.
