Trenchless Sewer Repair vs Traditional: Pros, Cons, and When Each Wins
March 9, 2026
Quick Answer
Trenchless sewer repair can reduce excavation and restore service with less disruption, but it requires the line to be a good candidate. Traditional excavation is sometimes necessary when the line is collapsed, misaligned, or inaccessible for trenchless methods.
Start with inspection
A sewer camera inspection clarifies the cause: roots, offsets, breaks, scale, or collapse.
When trenchless is a great fit
- Localized damage with a viable host pipe
- You want minimal landscape disruption
- Long runs under concrete or hardscape
When excavation may be necessary
- Collapsed or severely misaligned pipe
- Major section replacement needed
- Access limitations prevent trenchless equipment
