“Trenchless” means repairing a failed sewer line without excavating its full length — one or two access pits instead of a trench through the yard, the driveway, or the roots of the oak that made this neighborhood worth living in. Two methods dominate. They are not interchangeable, and the honest comparison — including when neither wins — is below.

A resin-saturated liner goes into the existing pipe, inflates, and cures into a new jointless pipe inside the old one. Strengths: minimal digging; no joints for roots; handles cracked clay and moderate deterioration well. Limits: the host pipe must hold its shape — collapses can’t be lined; bellies stay bellies (the liner follows the sag); diameter narrows slightly; badly deformed Orangeburg is a footage-based judgment call and often a no.
A bursting head pulls through the old line, fracturing it outward while dragging new HDPE pipe in behind. Strengths: full replacement at full diameter, no dependence on the old pipe’s shape — the right trenchless answer for collapsed lines and far-gone Orangeburg. Limits: needs entry and exit pits, and utility congestion or soil conditions can rule it out.
Open excavation is the right call more often than trenchless marketing admits: full collapses, severe bellies (re-laying pipe at correct slope is the only true fix), shallow lines under plain lawn, short runs. In those cases it’s frequently the cheapest bid. Trenchless earns its premium when what’s above the pipe — concrete, additions, mature trees — costs more than the pipe. The dig option in full: sewer line replacement.
Full-lateral trenchless work commonly quotes $4,000–$15,000 depending on length, depth, method, and access; spot repairs less; excavation varies widest. The sequence that protects you never changes: camera first, then multiple written itemized estimates from licensed plumbing contractors — and a recommendation backed by footage you’ve seen with your own eyes.
