Thermal Imaging for Slab Leaks in Lake Oswego, OR
Thermal imaging cameras allow us to visualize 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 significantly without any physical disruption to your property in Lake Oswego.

Hot Water Slab Leak Detection in Lake Oswego
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 nonstop 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.
Slab Leak Detection and Repair Cost Comparison in Lake Oswego, OR
Slab leak detection usually costs $150 to $450. Direct access repairs usually run $1,000 to $3,000, including concrete patching but not flooring replacement. Reroutes generally cost $800 to $3,500 depending on distance and access. Full repipes cost more, often $4,000 to $15,000, but end the problem permanently.
Post-Tension Slab Leak Detection in Lake Oswego
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.
Video Pipe Inspection for Sewer Leaks in Lake Oswego, OR
Sewer line issues under a slab can also look like slab leak symptoms. We use high-resolution video cameras to inspect the interior of your drain lines, identifying cracks, blockages or separations. This is vital if the issue isn't a pressurized water line, helping us determine if a sewer line repair is needed instead for your Lake Oswego home.
