Some sewer lines are too far gone to repair. They are collapsed, badly offset, sagging or built from fragile materials. Trenchless sewer replacement installs a completely new line without excavating its full length. By bursting or pulling new pipe through the old path, you get a fresh sewer with fused joints, while your yard, driveway, sidewalk and landscaping stay largely in place.
We camera the line, map the route and decide between replacement methods, usually pipe bursting, splitting or a pull-in approach. Small pits are dug at the ends, new pipe is pulled in, and connections are made and tested. We explain every choice, compare it with lining and tell you honestly when lining is simpler. You receive a written scope before any work starts.
