Sewer Line Slab Leak Repair in Fargo, ND
Slab leaks aren't always about clean water pipes, since sewer lines can also leak under your foundation. These leaks pose serious health risks and can cause extensive damage. We specialize in detecting and repairing sewer line slab leaks, using camera inspections to identify the exact problem area. Our methods restore proper waste removal and prevent contamination in your Fargo, ND property, following health and safety codes.

Spot Repair Through the Slab in Fargo, ND
When the leak is isolated and the rest of the pipe is in good shape, a spot repair through the slab is a sensible option. We cut a small opening, excavate to the pipe and replace the damaged section. The trench is compacted and the concrete is patched. Flooring is then restored by your preferred contractor.
Commercial Slab Leak Repair in Fargo, ND
Businesses in Fargo also face the risk of slab leaks, which can disrupt operations and lead to costly downtime. HPN Plumbing provides comprehensive commercial slab leak repair services, suited to the specific needs of your business. We work fast to diagnose and fix the problem, so your commercial property in North Dakota can return to normal operations with minimal interruption while staying safe and compliant.
Slab Leak Reroute in Fargo
Rerouting is often the best long-term choice, especially with older copper lines. We abandon the leaking line under the slab and run a new PEX line through the attic and walls. Openings are small and placed where patching is easiest. Reroutes end future leaks in that section of pipe.
Direct Slab Penetration Repair in Fargo, ND
When a slab leak is directly accessible and localized, direct slab penetration is often the most efficient repair method. This involves carefully cutting a small section of your concrete slab to access and repair or replace the damaged pipe section. Our team makes sure the repair is fully compliant with North Dakota plumbing codes and the slab is correctly restored, preventing future issues. We take great care to contain dust and debris during this process in your Fargo home.
Pipe Rerouting and Repiping in Fargo
For more extensive damage, multiple leaks, or pipes that are too old and corroded to repair reliably, pipe rerouting is a long-term solution. This involves abandoning the leaking line under the slab and installing a new pipe through the walls or attic. This method bypasses the problem area entirely, providing a fresh, durable plumbing line. It is a common solution for aging homes in Fargo with original copper or galvanized plumbing.
