Sewer Line Replacement Cost in Friendswood: Trenchless vs Open Trench
Sewer line replacement is a four-figure plumbing project on the small end and a five-figure one on the large end. Here is honest 2026 Friendswood market pricing by method.
Trenchless Pipe-Bursting: $135 to $225 per foot
Pipe-bursting pulls a new HDPE line through the existing path. Only two small access pits needed. For a typical Friendswood lateral of 50 to 100 feet, total project cost runs $6,750 to $22,500 all-in including permit, access-pit excavation, sod restoration, and 25-year pipe warranty.
CIPP Epoxy Lining: $145 to $215 per foot
CIPP is a liner saturated with epoxy, inflated inside the existing pipe, and cured to form a seamless new pipe-within-a-pipe. Best for lines that are structurally sound but have offset joints or small cracks letting roots in.
Open-Trench Replacement: $85 to $225 per foot
Traditional dig-and-replace. Lower per-foot pipe cost but higher total cost once restoration is counted.
- Per-foot pipe + labor: $85 to $225
- Driveway restoration (if applicable): $1,200 to $4,500
- Sidewalk restoration: $400 to $1,200
- Mature tree root pruning or tree loss: $0 to $3,000+
- Sprinkler system repair after dig: $200 to $800
- Landscape and sod restoration: $600 to $2,500
Spot Repair: $500 to $1,500 per single joint
When a camera inspection shows a single clearly-located failure, a spot repair digs only that joint and replaces 2 to 4 feet of pipe.
Which Method Fits Your Friendswood Property?
- Collapsed clay lateral under mature trees: Pipe-bursting
- Structurally-sound lateral with multiple leaky joints: CIPP lining
- Single, specifically-located failure: Spot repair
- Short lateral (under 20 feet) with no landscape overhead: Open-trench
