Hot Water Slab Leak Detection in Gresham
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 Gresham, OR
Slab leak detection typically 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 for good.
Slab Leak Reroutes in Gresham
Rerouting abandons the leaking line under the slab and runs new pipe through the walls or attic. It avoids breaking concrete and often costs less than direct access under finished floors. We typically use PEX for reroutes because it handles heat and resists hard-water corrosion. This option is a good fit when the slab is covered in tile or hardwood.
Emergency Slab Leak Response in Gresham
A slab leak that is flooding floors or causing water to bubble up through tile needs fast attention. We respond quickly, help you shut off the water and isolate the leaking side if possible. That often lets you keep partial water service until the repair. Then we locate and fix the leak.
Water and Sewer Line Slab Leaks in Gresham, OR
Slab leaks can affect both freshwater supply lines and sewer drain pipes. Our detection services are equipped to identify both types of leaks, which present different challenges. Sewer line leaks often involve foul odors and slow drainage, while water line leaks can appear as wet spots or high water bills in your Gresham, OR home. We have specific methods for each.
Electronic Acoustic Leak Detection in Gresham
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 especially effective for copper and PEX lines commonly found in Gresham homes.
Thermal Imaging for Slab Leaks in Gresham, OR
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 significantly without any physical disruption to your property in Gresham.
