Pressure Testing & Isolation in Olympia
When a leak is suspected, we can perform pressure tests on individual water lines. By isolating sections of your plumbing system and monitoring pressure gauges, we can confirm the presence of a leak and often determine which particular line is compromised. This step-by-step approach is crucial for homes with complex plumbing layouts, giving you an accurate diagnosis before any excavation in Olympia, WA.

Water and Sewer Line Slab Leaks in Olympia, WA
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 show up as wet spots or high water bills in your Olympia, WA home. We have specific methods for each.
Non-Invasive Leak Detection in Olympia, WA
Our primary goal is to locate your slab leak with the least amount of disruption possible. We prioritize non-invasive techniques like acoustic and thermal imaging before considering any intrusive methods. This approach saves your home in Olympia, WA from unnecessary damage, preserves your landscaping and reduces the overall cost and time of the repair process.
Electronic Acoustic Leak Detection in Olympia
Our team uses electronic listening devices to pinpoint the exact 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 Olympia homes.
Hot Water Slab Leak Detection in Olympia
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 marking the spot.
Repiping After Multiple Slab Leaks in Olympia, 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 repeat slab leaks. We can typically complete a full repipe in two to four days.
Acoustic Slab Leak Detection in Olympia
Our technicians use highly sensitive acoustic listening devices to pinpoint the exact location of a leak under your slab. This method involves listening for the faint 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 Olympia home.

Emergency Slab Leak Response in Olympia
A slab leak that is flooding floors or causing water to bubble up through tile needs quick attention. We respond quickly, help you shut off the water and isolate the leaking side if possible. That often lets you keep some water service until the repair. Then we locate and fix the leak.
