Electronic Acoustic Leak Detection in Lewiston
Our team uses electronic listening devices to pinpoint the exact location of a slab leak.

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 Lewiston homes.
Slab Leak Repair Through Direct Access in Lewiston, ID
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 it can be.
Slab Leak Detection and Repair Cost Comparison in Lewiston, ID
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 for good.
Cost-Effective Slab Leak Detection in Lewiston
Investing in professional slab leak detection with HNV Plumbing is a cost-effective solution compared to the long-term damage of an undetected leak.

Water and Sewer Line Slab Leaks in Lewiston, ID
Slab leaks can affect both freshwater supply lines and sewer drain pipes. Our detection services are set up 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 Lewiston, ID home. We have separate methods for each.
Repiping After Multiple Slab Leaks in Lewiston, ID
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 typically complete a full repipe in two to four days.

Slab Leak Reroutes in Lewiston
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 usually use PEX for reroutes because it handles heat and resists hard-water corrosion. This option is popular when the slab is covered in tile or hardwood.
