Tunneling for Foundation Leaks in Bellingham, WA
In some cases, the best way to repair a foundation leak is by tunneling beneath the slab. This method allows our plumbers to reach the damaged pipe directly without breaking through your home's interior flooring. FHN Plumbing is experienced in safe and efficient tunneling, minimizing disruption to your Bellingham, WA home and ensuring a complete repair of the damaged pipe section.
Water Line Reroute in Bellingham
Rerouting abandons the leaking line under the foundation and runs a new line through the attic or walls. This avoids breaking concrete and removes the risk of future leaks under the slab. We typically use PEX for reroutes because it is flexible and resists corrosion. Drywall openings are kept small and neat for easy patching.
Basement Wall Sealing and Waterproofing in Bellingham, WA
For homes with basements in Bellingham, WA, wall leaks can be a significant concern. We offer complete basement waterproofing services, including interior and exterior sealing.
