True Plumbing offers trenchless sewer line replacement. There are multiple ways to replace sewer lines, but trenchless replacement is by far the best method to reduce the amount of excavation to your lawn, foundation, flooring, and more. By using this process, we avoid digging up large sections of your property and use a sophisticated machine to feed a flexible liner inside the existing pipe that hardens after it's installed. This completely replaces the old pipe and provides a 100% newly sealed pipe.
