About this calculator

Sewer line issues are the most-feared inspection finding — high cost, invasive repair, and often invisible until failure. Modern trenchless methods (CIPP lining, pipe bursting) cost more per foot but preserve landscaping. This calculator gives you a realistic range based on damage type, material, and repair method.

Frequently asked questions

What's the difference between trenchless and trenched sewer repair?
Trenched excavates the entire line, replacing it section by section — $5,000–$13,000 for 60 ft. Trenchless uses CIPP (a liner cured inside the existing pipe) or pipe-bursting (pulls new pipe through the old) — $6,000–$15,000 for 60 ft, but preserves your landscaping. CIPP doesn't fix bellies or collapses; pipe-bursting does.
How much does Orangeburg pipe replacement cost?
Orangeburg (tar-impregnated paper pipe, installed 1945-1972) has a documented ~50-year lifespan and is now 50+ years old. Replacement is mandatory, not optional. Typical cost: $7,000-$18,000 for a 60 ft main with trenchless pipe-burst. Cheaper if trenched and landscaping is bare.
Should I ask the seller to fix sewer line issues before closing?
No — request a seller credit at the upper end of your repair range, then choose your own specialist and method post-close. Sellers tend to pick the cheapest contractor and trenched method; you may prefer trenchless. A credit gives you control.
What's a sewer scope inspection — and do I need one?
A sewer scope sends a camera through your cleanout or roof vent down to the city main, recording video of pipe condition, material, length, and any issues. Cost: $250-600. Recommended for ANY home over 30 years old or with mature trees within 30 feet. Single best preventive purchase in a home inspection.
