Why trenchless is usually the better choice

You skip the trench

An open replacement follows the lateral from the house to the street, through whatever is on top of it: lawn, driveway, walkway, planter beds, sidewalk, sometimes the road. Trenchless work reaches the pipe through the cleanout or a pit at each end. Everything in between stays as it is.

You skip the restoration bill

The cost of a trench is rarely the digging. It is the concrete that goes back, the landscaping that gets replanted, the sidewalk that must meet city standards, and the street cut with its permit and traffic control. Trenchless work is priced on the pipe, not on the property above it.

You skip the week

Most residential lining or bursting jobs finish in a day, with water off for a few hours. An open replacement is days of excavation, inspection and backfill, followed by weeks of restoration.

You skip the joints

Old clay and cast iron laterals fail at the joints, which is where roots enter and where the pipe shifts. A cured liner and a fused HDPE pipe have no joints. That is why lining and bursting are rated in decades, not years.

When digging still wins

A short collapsed section under open lawn may be cheaper to dig and replace than to burst. A line that runs within inches of a foundation footing is not a bursting candidate. A lateral that has lost grade over most of its length may need a new route. A good contractor tells you this from the camera footage instead of selling you a method.
