| How it works | Repair or replace the pipe through 1–2 small access pits | Dig an open trench along the full line; remove and replace the pipe |
|---|
| Typical timeline | Most jobs done in one day | 3–5 days of digging, plus 1–2 weeks of restoration |
|---|
| Property disruption | Two small pits; yard, driveway, and patio untouched | Trench through everything above the line — lawn, concrete, landscaping |
|---|
| Restoration needed | Minimal — backfill two pits, reseed small patches | Rebuild driveways/patios, replace sod, repair irrigation |
|---|
| Per-foot repair cost | Often higher per foot ($80–$250 estimated range) | Often lower per foot ($50–$150 estimated range) |
|---|
| Total project cost | Frequently lower — no restoration bill | Often higher once restoration is added |
|---|
| Pipe longevity | New HDPE pipe or seamless liner; no joints for roots to enter | New pipe, but joints remain root-entry points over time |
|---|
| Works under structures | Yes — under driveways, patios, additions, and trees | Requires demolishing and rebuilding anything above the line |
|---|
| Best for | Cracked, root-invaded, or deteriorated lines that still have a path | Fully collapsed lines, major reroutes, or pipes that must change direction |
